* Updated to Pixi v2.2.0 - see separate change log entry below.
* Cache.getRenderTexture will retrieve a RenderTexture that is stored in the Phaser Cache. This method replaces Cache.getTexture which is now deprecated.
* Cache.autoResolveURL is a new boolean (default `false`) that automatically builds a cached map of all loaded assets vs. their absolute URLs, for use with Cache.getURL and Cache.checkURL. Note that in 2.1.3 and earlier this was enabled by default, but has since been moved behind this property which needs to be set to `true`*before* you load any assets to enable.
* You can now call Tween.to again on a Tween that has already completed. This will re-use the same tween, on the original object, without having to recreate the Tween again. This allows a single tween instance to be re-used multiple times, providing they are linked to the same object (thanks InsaneHero)
* Phaser.Color.valueToColor converts a value: a "hex" string, a "CSS 'web' string", or a number - into red, green, blue, and alpha components (thanks @pnstickne#1264)
* Stage.backgroundColor now supports CSS 'rgba' values, as well as hex strings and hex numbers (thanks @pnstickne#1234)
* Pointer.addClickTrampoline now adds in support for click trampolines. These raise pointer events into click events, which are required internally for a few edge cases like IE11 full screen mode support, but are also useful if you know you specifically need a DOM click event from a pointer (thanks @pnstickne#1282)
* Point.floor will Math.floor both the `x` and `y` values of the Point.
* Point.ceil will Math.ceil both the `x` and `y` values of the Point.
* ScaleManager.scaleSprite takes a Sprite or Image object and scales it to fit the given dimensions. Scaling happens proportionally without distortion to the sprites texture. The letterBox parameter controls if scaling will produce a letter-box effect or zoom the sprite until it fills the given values.
* Phaser.DOM.getBounds is a cross-browser element.getBoundingClientRect method with optional cushion.
* Phaser.DOM.calibrate is a private method that calibrates element coordinates for viewport checks.
* Phaser.DOM.aspect gets the viewport aspect ratio (or the aspect ratio of an object or element)
* Phaser.DOM.inViewport tests if the given DOM element is within the viewport, with an optional cushion parameter that allows you to specify a distance.
* Phaser.DOM.viewportWidth returns the viewport width in pixels.
* Phaser.DOM.viewportHeight returns the viewport height in pixels.
* Phaser.DOM.documentWidth returns the document width in pixels.
* Phaser.DOM.documentHeight returns the document height in pixels.
* TilemapLayers have been given a decent performance boost on canvas with map shifting edge-redraw (thanks @pnstickne#1250)
* A large refactor to how the internal game timers and physics calculations has been made. We've now swapped to using a fixed time step internally across Phaser, instead of the variable one we had before that caused glitchse on low-fps systems. Thanks to pjbaron for his help with all of these related changes.
* We have separated the logic and render updates to permit slow motion and time slicing effects. We've fixed time calling to fix physics problems caused by variable time updates (i.e. collisions sometimes missing, objects tunneling, etc)
* Once per frame calling for rendering and tweening to keep things as smooth as possible
* Calculates a `suggestedFps` value (in multiples of 5 fps) based on a 2 second average of actual elapsed time values in the `Time.update` method. This is recalculated every 2 seconds so it could be used on a level-by-level basis if a game varies dramatically. I.e. if the fps rate consistently drops, you can adjust your game effects accordingly.
* Game loop now tries to "catch up" frames if it is falling behind by iterating the logic update. This will help if the logic is occasionally causing things to run too slow, or if the renderer occasionally pushes the combined frame time over the FPS time. It's not a band-aid for a game that floods a low powered device however, so you still need to code accordingly. But it should help capture issues such as gc spikes or temporarily overloaded CPUs.
* It now detects 'spiraling' which happens if a lot of frames are pushed out in succession meaning the CPU can never "catch up". It skips frames instead of trying to catch them up in this case. Note: the time value passed to the logic update functions is always constant regardless of these shenanigans.
* Signals to the game program if there is a problem which might be fixed by lowering the desiredFps
* Time.desiredFps is the new desired frame rate for your game.
* Time.suggestedFps is the suggested frame rate for the game based on system load.
* Time.slowMotion allows you to push the game into a slow motion mode. The default value is 1.0. 2.0 would be half speed, and so on.
* Time.timeCap is no longer used and now deprecated. All timing is now handled by the fixed time-step code we've introduced.
* Time.now can no longer be relied upon to contain a timestamp value. If the browser supports requestAnimationFrame then `Time.now` will contain the high resolution timer value that rAf generates. Otherwise it will contain the value of Date.now. If you require the actual time value (in milliseconds) then please use `Time.time` instead. Note that all Phaser sub-systems that used to rely on `Time.now` have been updated, so if you have any code that extends these please be sure to check it.
* Game.forceSingleUpdate will force just a single logic update, regardless of the delta timer values. You can use this in extremely heavy CPU situations where you know you're about to flood the CPU but don't want Phaser to get stuck in a spiral.
* Tilemap.createFromTiles will convert all tiles matching the given tile index (or an array of indexes) into Sprites. You can optionally then replace these tiles if you wish. This is perfect for games when you want to turn specific tiles into Sprites for extra control. The Sprites have an optional properties object which they can be populated with.
* Added support for the Wheel Event, which is the DOM3 spec (thanks @pnstickne#1318)
* Wheel Scroll Event (old non-FF) and DOM Mouse Wheel (old FF) are
supported via a non-exported reused wrapper object; WheelEventProxy.
The proxy methods are generated one-time dynamically but only when needed.
* Key.justDown allows you to test if a Key has just been pressed down or not. You can only call justDown once per key press. It will only return `true` once, until the Key is released and pressed down again. This allows you to use it in situations where you want to check if this key is down without using a Signal, such as in a core game loop (thanks @pjbaron#1321)
* Key.justUp allows you to test if a Key has just been released or not. You can only call justUp once per key press. It will only return `true` once, until the Key is pressed down and released again. This allows you to use it in situations where you want to check if this key is up without using a Signal, such as in a core game loop (thanks @pjbaron#1321)
* Device.whenReady is a new signal that you can use to tell when the device is initialized.
* Device.onInitialized is dispatched after device initialization occurs but before any of the ready callbacks have been invoked. Local "patching" for a particular device can/should be done in this event.
* TweenManager.removeFrom method allows you to remove a tween from a game object such as a Sprite (thanks @lewster32#1279)
* Tweens have been completely rewritten. They're now much more flexible and efficient than before:
* When specifying the ease in `Tween.to` or `Tween.from` you can now use a string instead of the Function. This makes your code less verbose. For example instead of `Phaser.Easing.Sinusoidal.Out` and you can now just use the string "Sine".The string names match those used by TweenMax and includes: "Linear", "Quad", "Cubic", "Quart", "Quint", "Sine", "Expo", "Circ", "Elastic", "Back", "Bounce", "Power0", "Power1", "Power2", "Power3" and "Power4". You can append ".easeIn", ".easeOut" and "easeInOut" variants. All are supported for each ease types.
* Tweens now create a TweenData object. The Tween object itself acts like more of a timeline, managing multiple TweenData objects. You can now call `Tween.to` and each call will create a new child tween that is added to the timeline, which are played through in sequence.
* Tweens are now bound to the new Time.desiredFps value and update based on the new Game core loop, rather than being bound to time calculations. This means that tweens are now running with the same update logic as physics and the core loop.
* Tween.timeScale allows you to scale the duration of a tween (and any child tweens it may have). A value of 1.0 means it should play at the desiredFps rate. A value of 0.5 will run at half the frame rate, 2 at double and so on. You can even tween the timeScale value for interesting effects!
* Tween.reverse allows you to instantly reverse an active tween. If the Tween has children then it will smoothly reverse through all child tweens as well.
* Tween.repeatAll allows you to control how many times all child tweens will repeat before firing the Tween.onComplete event. You can set the value to -1 to repeat forever.
* Tween.loop now controls the looping of all child tweens.
* Tween.onRepeat is a new signal that is dispatched whenever a Tween repeats. If a Tween has many child tweens its dispatched once the sequence has repeated.
* Tween.onChildComplete is a new signal that is dispatched whenever any child tweens have completed. If a Tween consists of 4 sections you will get 3 onChildComplete events followed by 1 onComplete event as the final tween finishes.
* Chained tweens are now more intelligently handled. Because you can easily create child tweens (by simply calling Tween.to multiple times) chained tweens are now used to kick-off longer sequences. You can pass as many Tween objects to `Tween.chain` as you like as they'll all be played in sequence. As one Tween completes it passes on to the next until the entire chain is finished.
* Tween.stop has a new `complete` parameter that if set will still fire the onComplete event and start the next chained tween, if there is one.
* Tween.delay, Tween.repeat, Tween.yoyo, Tween.easing and Tween.interpolation all have a new `index` parameter. This allows you to target specific child tweens, or if set to -1 it will update all children at once.
* Tween.totalDuration reports the total duration of all child tweens in ms.
This changes the current scaling behavior as seen in "Game Scaling" (as it
will only scale for the right edge) but also prevents such scaling from
going bonkers in some mobile environments like the newer Android browser.
(Automatic scroll-to-top, albeit configurable, enabled for non-desktop by
default is not a fun situation here.)
To obtain the current semantics on a desktop the bottom should be changed
to 'layout'; although this will result in different behavior depending on
mobile device. To make the sizing also follow mobile zooming they should
be changed to 'visual'.
Also added temp Rectangle re-used for various internal calculations.
* Phaser.DOM now also special-cases desktops to align the layout bounds
correctly (this may disagree with CSS breakpoints but it aligns the with
actual CSS width), without applying a window height/width expansion as
required on mobile browsers.
* Signals have been heavily restructured to cut down on the number that are generated in-game. New signal proxies manage the setting and creation as required, cutting down on the volume of run-time object creation significantly. No user code needs to change, however if you did override Phaser.Signal or Sprite.Events then please be aware of the changes by inspecting the source (and commit #1389 by @pnstickne).
* Game.lockRender is a new property. If `false` Phaser will automatically render the display list every update. If `true` the render loop will be skipped. You can toggle this value at run-time to gain exact control over when Phaser renders. This can be useful in certain types of game or application. Please note that if you don't render the display list then none of the game object transforms will be updated, so use this value carefully.
### Updates
* TypeScript definitions fixes and updates (thanks @clark-stevenson @draconisNoctis)
* The TypeScript definitions have moved to the `typescript` folder in the root of the repository.
* Cache._resolveUrl has been renamed to Cache._resolveURL internally and gained a new parameter. This method is a private internal one.
* Cache.getUrl is deprecated. The same method is now available as Cache.getURL.
* Loader.useXDomainRequest used to be enabled automatically for IE9 but is now always set to `false`. Please enable it only if you know your server set-up / CDN requires it, as some most certainly do, but we're finding them to be less and less used these days, so we feel it's safe to now disable this by default (#1248)
* Game.destroy now destroys either the WebGLRenderer or CanvasRenderer, whichever Pixi was using.
* Particle.Emitter will now automatically set `particle.body.skipQuadTree` to `true` to help with collision speeds within Arcade Physics.
* Particle.Emitter.explode (or `Emitter.start` with the `explode` parameter set to `true`) will immediately emit the required quantity of particles and not delay until the next frame to do so. This means you can re-use a single emitter across multiple places in your game that require explode-style emissions, just by adjusting the `emitter.x` and `emitter.y` properties before calling explode (thanks Insanehero)
* Phaser.Polygon has been refactored to address some Pixi v2 migration issues (thanks @pnstickne for the original implementation #1267)
* Polygon.area is now only calculated when the Polygon points list is modified, rather than on every call.
* Phaser.Polygon can now accept the points list in a variety of formats: Arrays of Points, numbers, objects with public x/y properties or any combination of, or as a parameter list (thanks @pnstickne for the original implementation #1267)
* All of the Input classes now use the more consistent `enabled` property instead of `disabled`. I.e. you can now check `if (input.mouse.enabled)` rather than `if (!input.mouse.disabled)`. The disabled property has been moved to a getter for backwards compatibility but is deprecated and will be removed in a future version (thanks @pnstickne#1257)
* The Input class has been given a minor refactor to tidy things up. Specifically:
* pointerN are aliases to backed pointers[N-1] array. This simplifies (and increases the efficiency of) looping through all the pointers when applicable; also eliminates pointer-existence checks Removes various hard-coded limits (added MAX_POINTERS); changed maxPointers default
* Removed some special-casing from cases where it did not matter
* Removed === false/true, == usage for consistency, changed missing value check to typeof, etc.
* Updated documentation for specificity; added @public\@protected
*@deprecated currentPointers due to odd set pattern; totalCurrentPointers is more appropriate.
(thanks @pnstickne#1283)
* Various ScaleManager fixes and updates (thanks @pnstickne):
* Scale modes can now be set independently
* Switching between fullscreen and normal correctly restores modes
* Alignment does not incorrectly offset in fullscreen mode (#1255)
* NO_SCALE should not not scale (vs previous behavior of having no behavior)
* Correct usage of scaleMode depending on mode
* Fullscreen Mode always scaling to fill screen in Firefox (#1256)
* AudioSprite - removed an unnecessary if-statement (thanks @DaanHaaz#1312)
* ArcadePhysics.skipQuadTree is now set to `true` by default. A QuadTree is a wonderful thing if the objects in your game are well spaced out. But in tightly packed games, especially those with tilemaps or single-screen games, they are a considerable performance drain and eat up CPU. We've taken the decision to disable the Arcade Physics QuadTree by default. It's all still in there and can be re-enabled via `game.physics.arcade.skipQuadTree = false`, but please only do so if you're sure your game benefits from this.
* Phaser.DOM now houses new DOM functions. Some have been moved over from ScaleManager as appropriate.
* Key.justPressed has bee renamed to Key.downDuration which is a much clearer name for what the method actually does. See Key.justDown for a nice clean alternative.
* Key.justReleased has bee renamed to Key.upDuration which is a much clearer name for what the method actually does. See Key.justUp for a nice clean alternative.
* Keyboard.justPressed has bee renamed to Keyboard.downDuration which is a much clearer name for what the method actually does.
* Keyboard.justReleased has bee renamed to Keyboard.upDuration which is a much clearer name for what the method actually does.
* Keyboard.downDuration, Keyboard.upDuration and Keyboard.isDown now all return `null` if the Key wasn't found in the local keys array.
* The Phaser.Device class has been made into a singleton and removed it's dependency on Phaser.Game (thanks @pnstickne#1328)
* ArrayList has been renamed to `ArraySet` (as it's actually a data set implementation) and moved from the `core` folder to the `utils` folder (thanks @pnstickne)
* If you are reloading a Phaser Game on a page that never properly refreshes (such as in an AngularJS project) then you will quickly run out of AudioContext nodes. If this is the case create a global var called `PhaserGlobal` on the window object before creating the game. The active AudioContext will then be saved to `window.PhaserGlobal.audioContext` when the Phaser game is destroyed, and re-used when it starts again (#1233)
* Camera.screenView is now deprecated. All Camera culling checks are made against Camera.view now instead.
* Various CocoonJS related hacks removed thanks to fixes from Ludei directly in CocoonJS! Woohoo :)
* Phaser.HEADLESS check removed from the core game loop. If you need to disable rendering you can now override the Phaser.Game.updateRender method instead with your own.
* Group.forEach fixed against browser de-optimization (thanks @pnstickne#1357)
* Phaser.Signals have been taken on a diet. They have been updated such that there is significantly less penalty for having many unused signals. The changes include:
* * Changing it so there is no dispatch *closure* created. This is a
potentially breaking change for third party code.
* * In the rare case that code needs to obtain a dispatch-closure, the
`boundDispatch` property can be used to trivially obtain a cached
closure.
* * The properties and default values are moved into the prototype; and the
_bindings array creation is deferred. This change, coupled with the
removal of the automatic closure, results in a very lightweight
~24bytes/object (in Chrome) for unbound signals.
* With this change in place Signals now consume less than 50KB / 50KB (shallow / retained memory) for 200 sprites, where-as before they used 300KB / 600KB (thanks @pnstickne#1359)
* Time.elapsedMS holds the number of milliseconds since the last Game loop, regardless of raF or setTimout being used.
* Incorrectly prepared tilemap images (with dimensions not evenly divisible by the tile dimensions) would render incorrectly when compared to the display seen in Tiled. The Phaser tilemap code has been adjusted to match the way Tiled deals with this, which should help if you're using tileset images that contain extra padding/margin pixels. Additional console warnings have been added. However the fact remains that you should carefully prepare your tilesets before using them. Crop off extra padding, make sure they are the right dimensions (thanks @SoulBeaver for the report and @pnstickne for the fix #1371)
* Text.setShadow has had the default `color` value changed from `rgba(0,0,0,0)` to `rgba(0,0,0,1)` so it appears as a black shadow by default - before the alpha channel made it invisible.
* Math.getRandom will now return `null` if random selection is missing, or array has no entries (thanks @pnstickne#1395)
* Array.transposeArray has had a small off-by-one error fixed. It didn't effect the results but meant returned arrays were 1 element bigger than needed (thanks @nextht#1394)
* State.preRender is now sent two parameters: a reference to the Phaser.Game instance and a new parameter: `elapsedTime` which is the time elapsed since the last update.
### Bug Fixes
* Tilemaps in WebGL wouldn't update after the first frame due to a subtle change in how Pixi uploads new textures to the GPU.
* XML files weren't being added to the URL map.
* Cache._resolveURL was causing a Sound double-load in Firefox and causing errors (thanks @domonyiv#1253)
* Loader.json was using the wrong context in IE9 with XDomainRequest calls (thanks @pnstickne#1258)
* Text.updateText was incorrectly increasing the size of the texture each time it was called (thanks @spayton#1261)
* Polygon.contains now correctly calculates the result (thanks @pnstickne@BurnedToast#1267)
* Setting Key.enabled = false while it is down did not reset the isDown state (thanks @pnstickne#1190#1271)
* The Gamepad.addCallbacks context parameter was never actually remembered, causing the callbacks to run in the wrong context (thanks @englercj#1285)
* Animation.setFrame used the wrong frames array if `useLocalFrameIndex` was `false` and a numeric frame ID was given (thanks @Skeptron#1284)
* Fullscreen mode in IE11 now works (thanks @pnstickne)
* Cache.addBitmapData now auto-creates a FrameData (thanks @pnstickne#1294#1300)
* P2.BodyDebug circles were drawing at half widths (thanks @enriqueto#1288)
* FrameData.clone fixed when cloning data using frame names rather than indexes (thanks pjbaron)
* Lots of the Cache getters (such as `Cache.getbitmapData`) would return `undefined` if the asset couldn't be found. They now all consistently return `null` for missing entries (thanks @Matoking#1305)
* Phaser games should now work again from the CocoonJS Launcher.
* Only one of the mouse wheel events is listened to, newest standard first.
This fixes a bug in FF where it would use the default DOMMouseWheel (thanks @pnstickne#1313)
* Stage.smoothed needed to modify the value of PIXI.scaleMode.DEFAULT instead of PIXI.scaleMode.LINEAR (thanks @pixelpicosean#1322)
* Newly created Groups always had zero z index (thanks @spayton#1291)
* Sprite.autoCull now properly works if the camera moves around the world.
* Sprite.inCamera uses a much faster check if auto culling or world bounds checks are enabled and properly adjusts for camera position.
* Camera.totalInView is a new property that contains the total number of Sprites rendered that have `autoCull` set to true and are within the Cameras view.
* Emitter.setScale fixed minX minY order precedence (thanks spayton)
* Group.iterate can now accept undefined/null as the arguments (thanks @pnstickne#1353@tasos-ch #1352)
* When you change State the P2 Physics world is no longer fully cleared. All of the bodies, springs, fixtures, materials and constraints are removed - but config settings such as gravity, restitution, the contact solver, etc are all retained. The P2.World object is only created the very first time you call Physics.startSystem. Every subsequent call hits P2.World.reset instead. This fixes "P2.World gravity broken after switching states" (and other related issues) (#1292 #1289#1176)
* Text.lineSpacing works correctly again. Before no space was added between the lines (thanks @intimidate#1367 and @brejep#1366)
* P2.BodyDebug always lagged behind the position of the Body it was tracking by one frame, which became visible at high speeds. It now syncs its position in the Body.postUpdate which prevents this from happening (thanks @valueerror)
* A State.preRender callback wasn't removed correctly when switching States.
### Pixi 2.1.0 New Features
* unloadFromGPU added to PIXI.BaseTexture
* PIXI.VideoTexture added
* PIXI.RoundedRectangle added
* Ensured all float32arrays use PIXI.Float32Array
* Removed the use of call in updateTransform (as its 10x faster to run the function directly)
* autoResize option added to renderer options (default is false). Pixi no longer automatically changes the style of the canvas.
* Happily removed the IE11 WebGL lock as Pixi now fully supports it :)
* Time.prevTime is a new property that contains the raw value of the game timer from the previous update.
* Sound.fadeTo allows you to fade the Sound to the given volume over the duration specified (thanks @nickryall#1225)
* BitmapData.getFirstPixel will scan the BitmapData and return the color and location of the first non-transparent pixel encountered. You can specify one of 4 scan directions: top to bottom, bottom to top, left to right and right to left.
* BitmapData.getBounds will return a `Rectangle` object that encompasses the full extent of the non-transparent pixels in the BitmapData. This can be useful if you wish to trim away transparent pixels from the sides of a BitmapData down to size before saving.
* Rectangle.scale allows you to scale the width and height of a Rectangle.
* RenderTexture has a new optional parameter: `resolution`
### Updates
* TypeScript definitions fixes and updates (thanks @clark-stevenson)
* Changed the Animation constructor parameter `delay` to `frameRate` as it's a more accurate term of what it should be. Internally nothing changed.
* Circle.getBounds added.
* Ellipse.getBounds added.
* Device.canPlayAudio now supports `opus` files directly, as well as `opus` encoded audio stored in ogg containers (#1232)
* PIXI.AbstractFilter is now bundled by default to support the new `sprite.shader` feature in Pixi v2.
* Changed all typeof comparisons from == to === (thanks @bobbywilson0#1230)
* JSDoc fixes in the Rope class (thanks @Rovanion)
* Filter.update now caches the previous pointer position to avoid flooding the uniform. Also the mouse uniform is now a value between 0 and 1 depending on the position within the game view.
### Bug Fixes
* Fixed a reference error to the Loader.baseURL in Cache._resolveUrl method. This stops the error where Safari would show lots of file load errors but then still load the files (thanks @neurofuzzy#1235)
* Fixed the Filter mouse uniform value population.
* Fixed an issue where audio files with query strings after them would fail the `canPlayAudio` checks (thanks Vithar)
* Input.hitTest now accurately detects hits on the extreme edges of a display object (thanks InsaneHero)
* Button.setSounds now works if given an AudioSprite as the sound source.
### Pixi v2 Specific New Features
* Sprites can now have a custom shader applied to them. Much better performance than filters.
* Renderers now have a resolution. Ideal for working with different pixel density.
* Big refactor of the webGLRenderer and WebGLSpriteBatch renderer.
* Refactor of CanvasRenderer.
* DisplayObject.updateTransform function rewritten with for better performance.
* New Events Class.
* New Constructor for all renderers (including autoDetect)
* Massive Refactor of Graphics (WebGL and Canvas)
* Graphics objects can now be interactive.
* Made removeChild no longer returns error.
* Lots of new functions added to the Matrix class.
* RenderTexture refactored. Now accepts Matrix in the render function.
* AsciiFilter, NoiseFilter and TiltShiftFilter.
* added getChildIndex and setChildIndex methods to DisplayObjectContainer.
## Version 2.1.2 - "Whitebridge" - 9th October 2014
### New Features
* StateManager.unlink will null all State-level Phaser properties, such as `game`, `add`, etc. Useful if you never need to return to the State again.
* Cache.removeImage has a new parameter: `removeFromPixi` which is `true` by default. It will remove the image from the Pixi BaseTextureCache as well as from the Phaser Cache. Set to false if you don't want the Pixi cache touched.
* Group.ignoreDestroy boolean will bail out early from any call to `Group.destroy`. Handy if you need to create a global Group that persists across States.
* Loader can now natively load XML files via `load.xml`. Once the XML file has loaded it is parsed via either DOMParser or ActiveXObject and then added to the Cache, where it can be retrieved via `cache.getXML(key)`.
* Cache now has support for XML files stored in their own container. You can add them with `cache.addXML` (typically this is done from the Loader automatically for you) and get them with `cache.getXML(key)`. There is also `cache.checkXMLKey(key)`, `cache.checkKeys` and `cache.removeXML(key)`.
* Rectangle.aabb is a new method that will take an array of Points and return a Rectangle that matches the AABB (bounding area) of the Points (thanks @codevinsky#1199)
* AudioSprite support is now built into the Loader and SoundManager. AudioSprites are like sprite sheets, only they consist of a selection of audio files and markers in a json configuration. You can find more details at https://github.com/tonistiigi/audiosprite (thanks @codevinsky#1205)
* Point.parse will return a new Point object based on the x and y properties of the object given to Point.parse (thanks @codevinsky#1198)
* Sound.fadeOut(duration) will fade the Sound to a volume of zero over the duration given. At the end of the fade the Sound will be stopped and Sound.onFadeComplete dispatched.
* Sound.fadeIn(duration, loop) will start the Sound playing, or restart it if already playing, set its volume to zero and then increase the volume over the duration given until it reaches 1. At the end of the fade the Sound.onFadeComplete event is dispatched.
* Text.addColor allows you to set specific colors within the Text. It works by taking a color value, which is a typical HTML string such as `#ff0000` or `rgb(255,0,0)` and a position. The position value is the index of the character in the Text string to start applying this color to. Once set the color remains in use until either another color or the end of the string is encountered. For example if the Text was `Photon Storm` and you did `Text.addColor('#ffff00', 6)` it would color in the word `Storm` in yellow.
* Text.clearColors resets any previously set colors from `Text.addColor`.
* If you pass a tinted Sprite to `BitmapData.draw` or `BitmapData.copy` it will now draw the tinted version of the Sprite to the BitmapData and not the original texture.
* BitmapData.shadow(color, blur, x, y) provides a quick way to set all the relevant shadow settings, which are then be used in future draw calls.
* Cache.addBitmapData has a new parameter: `frameData` allowing you to pass a `Phaser.FrameData` object along with the BitmapData.
* Cache.getFrameData has a new parameter: `map` which allows you to specify which cache to get the FrameData from, i.e. `Phaser.Cache.IMAGE` or `Phaser.Cache.BITMAPDATA`.
* Sprite.loadTexture if given a BitmapData as the texture will now query the cache to see if it has any associated FrameData, and if so it will load that into the AnimationManager.
* BitmapData.textureLine takes a Phaser.Line object and an image in the image cache. It then accurately draws the image as a repeating texture for the full length of the line.
* AnimationManager.name will now return the `name` property of the currently playing animation, if any.
* Group.filter takes a predicate function and passes child, index, and the entire child array to it. It then returns an ArrayList containing all children that the predicate returns true for (thanks @codevinsky#1187)
* Cache.checkUrl allows you to check if a resource is in the cache based on an absolute URL (thanks @englercj#1221)
* Cache.getUrl gets a resource from the cache based on the absolute URL it was loaded from (thanks @englercj#1221)
* Sound.allowMultiple allows you to have multiple instances of a single Sound playing at once. This is only useful when running under Web Audio, and we recommend you implement a local pooling system to not flood the sound channels. But it allows for one Sound object to play overlapping times, useful for gun effects and similar (#1220)
### Updates
* TypeScript definitions fixes and updates (thanks @clark-stevenson @englercj@benjamindulau)
* Added the `sourceRect` and `maskRect` parameters back into `BitmapData.alphaMask` as they were accidentally removed in 2.1 (thanks seejay92)
* jsdoc fixes (thanks @danxexe#1209)
* AnimationParser is now using `value` instead of `nodeValue` when parsing atlas XML files, avoiding Chrome deprecation warnings (thanks @valtterip#1189)
* Color.webToColor restored. Converts a CSS rgba color into a native color value.
* Color.createColor now populates the `color` property of the returned object with the results of `Phaser.Color.getColor`.
* Color.createColor now has a `color32` property with the results of `Phaser.Color.getColor32`.
* Color.hexToColor has been optimised to inline the regex and has moved the createColor call so it now populates the color object fully, not just setting the r,g,b properties.
* Keyboard.PLUS and Keyboard.MINUS have been added to the list of key codes (thanks @VictorBjelkholm#1281)
### Bug Fixes
* If Game Objects change their frame, such as with an animated Sprite, and the change goes from a previously trimmed frame to a non-trimmed (full size) one, then the previous trim values were still left active, causing it to glitch (thanks stupot)
* If you called StateManager.start from within a states `init` method which also had a `preload` method it would fail to start the next State.
* StateManager.boot would call start on a State twice if it was added to the game and started before the DOM load had completed. This didn't cause an error but was duplicating function calls needlessly.
* Changing any of the Text properties such as font, lineSpacing and fontSize on a Text object that wasn't already on the display list would cause an updateTransform error. Parent is now checked first in all setters.
* A Timer with a delay value that was a float and not an integer would not loop correctly. Timer delay values are now passed through Math.round to avoid this (thanks @osmanzeki#1196)
* The Loader would incorrectly call `fileComplete` for legacy audio files instead of setting it as a callback, throwing up errors if the audio file failed to load (thanks @spayton#1212)
* The Uint32Array check used in Utils was incorrectly replacing Uint32Array on Safari, causing errors like BitmapData.getPixel32 to fail and other related issues (fixes #1043 and #1197)
* Camera.follow would break if the parent of the Sprite being followed was scaled in any way (thanks @englercj#1222)
* Fixed the 4fv uniform in the Pixelate filter.
## Version 2.1.1 - "Eianrod" - 11th September 2014
Version 2.1.1. of Phaser is an emergency point release. It addresses a potential race condition that could happen in States that tried to change state from the create method but had an empty preloader or pre-cached assets.
## Version 2.1.0 - "Cairhien" - 9th September 2014
### New Features
* Updated to [p2.js 0.6.0](https://github.com/schteppe/p2.js/commit/d1c7a340c42e4d5d1d939fba5fd13c5e49d6abd2) - this was an API breaking change, so please see the p2.js section of this change log specifically if you're using p2 in your game.
* If you are using CocoonJS, please set your game render type to CANVAS and not WEBGL or AUTO. You should also disable any of the ScaleManager screen resizing or margin setting code. By default in this mode CocoonJS will now set 'screencanvas=true' which helps with performance significantly.
* Ninja Physics is no longer included in the build files by default. Not enough people were using it, and not enough contributions were coming in to help polish it up, so we've saved the space and removed it. It's still available in the grunt build files if you require it, but we're deprecating it from the core library at this time. It will make a return in Phaser3 when we move to a modular class system.
* ScaleManager has a new scaleMode called `RESIZE` which will tell Phaser to track the size of the parent container (either a dom element or the browser window if none given) and set the canvas size to match it. If the parent changes size the canvas will resize as well, keeping a 1:1 pixel ratio. There is also a new ScaleManager.setResizeCallback method which will let you define your own function to handle resize events from the game, such as re-positioning sprites for a fluid responsive layout (#642)
* The width and height given to the Phaser.Game constructor can now be numbers or strings in which case the value is treated as a percentage. For example a value of "100%" for the width and height will tell Phaser to size the game to match the parent container dimensions exactly (or the browser window if no parent is given). Equally a size of "50%" would tell it to be half the size of the parent. The values are retained even through resize events, allowing it to maintain a percentage size based on the parent even as it updates.
* Device will now detect for Kindle and PS Vita (thanks @lucbloom)
* Device will now detect for Cordova (thanks @videlais#1102)
* Arcade Physics Body.skipQuadTree is a new boolean that if set to `true` when you collide the Sprite against a Group it will tell Phaser to skip using a QuadTree for that collision. This is handy if this Body is especially large.
* Arcade Physics World.skipQuadTree will disable the use of all QuadTrees in collision methods, which can help performance in tightly packed scenes.
* Loader.useXDomainRequest boolean added. If `true` (the default is `false`, unless the browser is detected as being IE9 specifically) it will use XDomainRequest when loading JSON files instead of xhr. In rare IE edge-cases this may be required. You'll know if you need it (#1131 #1116)
* Added support for Tiled objects type field (thanks @rex64#1111)
* Tile properties are now copied from the Tiled JSON data to the Phaser.Tile objects when parsed (thanks @beeglebug#1126)
* All Images now have a frameData value, even if it's only one frame. This removes lots of engine code needed to check if images are sprite sheets or not, and simplifies game code too (thanks @lucbloom#1059)
* Added a new Phaser.Rope object. This allows for a series of 'chained' Sprites and extends the Rope support built into Pixi. Access it via game.add.rope (thanks @codevinsky#1030)
* Phaser.Device.isAndroidStockBrowser will inform you if your game is running in a stock Android browser (rather than Chrome) where you may wish to scale down effects, disable WebGL, etc (thanks @lucbloom#989)
* Phaser.Camera has a new property `position` which is a Point object that allows you to get or set the camera position without having to read both the x and y values (thanks @Zielak#1015)
* TileSprite now has the `alive` property, which should help with some Group operations (thanks @jonkelling#1085)
* Events.onDestroy is a new signal that is dispatched whenever the parent is being destroyed. It's dispatched at the start of the destroy process, allowing you to perform any additional house cleaning needed (thanks @jonkelling#1084)
* Group.onDestroy is a new signal that is dispatched whenever the Group is being destroyed. It's dispatched at the start of the destroy process, allowing you to perform any additional house cleaning needed (thanks @jonkelling#1084)
* ScaleManager.destroy now removes the window and document event listeners, which are no longer created anonymously (thanks @eguneys#1092)
* Input.Gamepad.destroy now destroys all connected SinglePads and clears event listeners.
* SinglePad.destroy now clears all associated GamepadButton objects and signals.
* Device.node and Device.nodeWebKit are two new properties (thanks @videlais#1129)
* P2.PointProxy.mx and my values are get and set in meters with no pixel conversion taking place.
* P2.InversePointProxy.mx and my values are get and set in meters with no pixel conversion taking place.
* Pointer.dirty is a new boolean that is set by the InputHandler. It tells the Pointer to re-check all interactive objects it may be over on the next update, regardless if it has moved position or not. This helps solve issues where you may have a Button that on click generates a pop-up window that now obscures the Button (thanks @jflowers45#882)
* SoundManager.destroy is a new method that will destroy all current sounds and reset any callbacks.
* StateManager.clearCurrentState now handles the process of clearing down the current state and is now called if the Game is destroyed.
* Game.destroy now clears the current state, activating its shutdown callback if it had one. It also now destroys the SoundManager, stopping any currently running sounds (#1092)
* Animation.onUpdate is a new event that is dispatched each time the animation frame changes. Due to its intensive nature it is disabled by default. Enable it with `Animation.enableUpdate = true` (#902)
* Device now has new features to support detection of running inside a CocoonJS.App (thanks @videlais#1150)
* Support for CocoonJS.App's 'onSuspended' and 'onActivated' events, making it so that the timers and sounds are stopped/started and muted/unmuted when the user swaps an app from the background to the fore or the reverse (thanks @videlais#1152)
* Canvas.removeFromDOM(canvas) will remove a canvas element from the DOM.
* Game.destroy now removes the games canvas element from the DOM.
* ScaleManager.setMinMax(minWidth, minHeight, maxWidth, maxHeight) is a handy function to allow you to set all the min/max dimensions in one call.
* ArcadePhysics.collide and overlap can now accept 2 Arrays of objects to be used in the collision checks (thanks @ctmartinez1992#1158)
* RetroFont has a new property called frameData which contains the Frame objects for each of the letters in the font, which can be used by Sprites.
* Phaser.Canvas.setImageRenderingCrisp now sets `image-rendering: pixelated`, perfect for pixel art, which is now supported in Chrome 38.
* Phaser.Mouse will now add a listener to the `window` to detect `mouseup` events. This is used to detect if the player releases the mouse while outside of the game canvas. Previously Pointer objects incorrectly thought they were still pressed when you returned the mouse over the canvas (#1167)
* Rectangle.centerOn(x,y) allows you to quickly center a Rectangle on the given coordinates.
* Group.addMultiple allows you to pass an array of game objects and they'll all be added to the Group in turn.
* The StateManager will now check if a State has a method called `resize`. If it does, and if the game is running in the RESIZE Scale Mode then this method will be called whenever the game resizes. It will be passed two parameters: `width` and `height` that will match the games new dimensions. Resizing can happen as a result of either the parent container changing shape, or the browser window resizing.
* Rectangle.topRight returns a Point object that represents the top-right coordinate of the Rectangle.
* The grunt script now builds a new version of Phaser without any physics (including Arcade Physics), Tilemaps or Particles. This build is called `phaser-no-physics.js` and works stand-alone. Please note that things like the GameObjectFactory aren't changed, so they will still try and create a Tilemap for example should you ask them to (thanks @eguneys#1172)
* Camera.roundPx is a new boolean. If set to `true` it will call `view.floor` as part of its update loop, keeping its boundary to integer values. Set to `false` to disable this from happening (#1141)
* Phaser.Easing.Default is a new property that is used when a specific type of ease isn't given. It defaults to Linear.None but can be overridden to anything (thanks @alvinsight)
### Updates
* TypeScript definition updates to help fix for the `noimplicitany` option (thanks @Waog#1088)
* TypeScript definitions fixes and updates (thanks @clark-stevenson @englercj@saikobee and @rhmoller)
* All of the Pixi geom classes have been removed from the build file as they aren't needed (the Phaser.Geom classes overwrite them), saving some space in the process.
* Improved consistency of clone methods on geometry classes (thanks @beeglebug#1130)
* Removed Cache.isSpriteSheet method as no longer required (see #1059)
* Added Cache.getFrameCount to return the number of frames in a FrameData.
* Input.setMoveCallback has been removed due to deprecation.
* BitmapData.refreshBuffer has been removed and replaced with BitmapData.update.
* BitmapData.drawSprite has been removed due to deprecation. Use BitmapData.draw instead.
* Pointer.moveCallback has been removed due to deprecation.
* SinglePad.addButton has been removed due to deprecation.
* P2.Body.loadData has been removed due to deprecation.
* P2.World.defaultFriction and defaultRestitution have been removed due to deprecation.
* Canvas.create noCocoon parameter has been removed due to deprecation.
* Color.getColorInfo, RGBtoHexstring, RGBtoWebstring and colorToHexstring has been removed due to deprecation.
* P2.PointProxy.x and y values are now returned in pixels (previously they were returned in meters). See PointProxy.mx/my for meter values.
* P2.InversePointProxy.x and y values are now returned in pixels (previously they were returned in meters). See PointProxy.mx/my for meter values.
* Arcade.overlap and collide are now more consistent about allowing a Group vs. Group or Group vs. Array of Groups set (thanks @pyromanfo#877#1147)
* The Pointer move callbacks are now sent an extra parameter: `fromClick` allowing your callbacks to distinguish between the Pointer just moving, or moving as a result of being pressed down (thanks @iforce2d#1055)
* GamePad and SinglePad onAxisCallback parameters have changed. You are now sent: this (a reference to the SinglePad that caused the callback), the axis index and the axis value in that order.
* If Time.elapsed was > Time.timeCap it would reset the elapsed value to be 1 / 60. It's now set to Time.timeCap and Time.timeCap defaults to `1 / 60 * 1000` as it's a ms value (thanks @casensiom#899)
* Tiled polylines are now imported into the map objects property as well as map collision (#1117)
* Tile.setCollision now adjusts the tiles interesting faces list as well, this allows you to create one-way jump tiles without using custom callbacks on a specific tile basis (thanks @RafaelOliveira#886)
* Stage.offset has been moved to ScaleManager.offset
* Stage.bounds has been removed, you can access it via Stage.getBounds.
* Stage.checkOffsetInterval has been moved to ScaleManager.trackParentInterval
* ScaleManager.hasResized signal has been removed. Use ScaleManager.setResizeCallback instead.
* The World bounds can now be set to any size, including smaller than the game dimensions. Before it was locked to a minimum size of the game canvas, but it can now be anything.
* ScaleManager.orientationSprite has been removed because it never displayed correctly anyway (it would be distorted by the game scale), it will be bought back in a future version by way of a custom orientation state.
* ArcadePhysics.overlap has been updated so that the Body.overlapX/Y properties are set to the amount the two bodies overlapped by. Previously they were zero and only populated during the separation phase, but now the data is available for just overlap checks as well. You can then use these values in your ovrelap callback as required - note that they are changed for every check, so a Sprite overlap tested against 10 other sprites will have the overlapX/Y values updated 10 times in a single collision pass, so you can only safely use the values in the callback (#641)
* Cache.getImage now returns `null` if the requested image wasn't found.
* BitmapData now returns a reference to itself from all of its drawing related methods, allowing for easy function chaining.
* The default size of a BitmapData if no width/height is given has been changed from 100x100 to 256x256.
* Phaser.Text.destroy will now destroy the base texture by default (#1162)
* BitmapData.copyPixels is now called BitmapData.copyRect and the method signature has changed.
* BitmapData.draw method signature has changed significantly.
* Phaser.Canvas.getSmoothingEnabled will return `true` if the given context has image smoothing enabled, otherwise `false`.
* Math.numberArrayStep is a new method that allows you to return an array of numbers from `min` to `max` including an optional `step` parameter (thanks @codevinsky#1170)
* Removed redundant `if` check from StateManager.preUpdate (thanks @FedeOmoto#1173)
### Bug Fixes

* Phaser.Loader was incorrectly getting the responseText from _xhr instead of _ajax on IE9 xDomainRequests (thanks @lardratboy#1050)
* Phaser.Physics.P2.addPolygon now takes a nested array again (thanks @wayfu#1060)
* Fix for previous PR #1028 where the P2.setBoundsToWorld call was overriding setBoundsToWorld in the P2 constructor (thanks @Dumtard#1028)
* Fix for scale issues in CocoonJS using webgl renderer and screencanvas (thanks @txusinho#1064)
* Resolves issue with pixel perfect click / over detection on Sprites that used trimmed image atlases for animations or frames > 0.

* Debug.cameraInfo no longer crashes if the camera bounds are nulled (thanks @wayfu#1143)
* Camera.setBoundsToWorld no longer crashes if the camera bounds are nulled (thanks @wayfu#1143)
* Fixed the resolution uniform type in the SampleFilter (thanks @VictoryRice#1137)
* Calling P2.Body.destroy or ArcadePhysics.Body.destroy wouldn't null the parent sprite body, causing it to error in the next update (thanks @jonathanhooker#1077)
* BitmapFonts are now correctly added to the Cache._bitmapFont array and returned via Cache.getBitmapFont (thanks @prudolfs#1076)
* InputHandler docs updated to avoid Pointer data-type confusion (#1097)
* If you used a single Game configuration object and didn't specify the enableDebug property it would crash on Debug.preUpdate (thanks @luizbills#1053)
* The P2.World.postBroadphaseHandler now checks if the returned pairs array is empty or not before processing it (thanks @wayfu#934)
* Tilemap.hasTile now checks the Tile.index value and will return false if the index is -1 (i.e. a non-active tile) (thanks @elgansayer#859)
* Sound.restart used to cause the Sound to double-up if it was already playing when called. Now correctly stops the sound before restarting it (thanks @wombatbuddy#1136)
* GamePad axis detection now works again properly in Firefox (#1035)
* GamepadButton.justPressed and justReleased now correctly report if the button has just been pressed or released (thanks @padpadpad#1019)
* TilemapParser.getEmptyData now correct adds an empty bodies array into layers. This fixes an issue where p2 couldn't convert a csv map into collision tiles (thanks @sru#845)
* CocoonJS doesn't support mouse wheel events so they've been moved into a conditional check (thanks @videlais#1151)
* ScaleManager window.resize handler would constantly dispatch enterPortrait and enterLandscape events on window resizing, regardless if it actually entered that orientation or not.
* Added Sound._muteVolume which stops Firefox and IE9 crashing if you try to unmute a sound that hasn't yet been muted, which can also happen as a result of a game visibility change (thanks @osmanzeki#1108#1123)
* P2.World.getSprings used to return an empty array, but now returns all the Springs in the world (#1134)
* Tween.generateData would skip the end values in the data array. They are now included as the object in the final array element.
* Rectangle.bottom setter swapped the order of the calculation (thanks @JakeCoxon#1165)
* Phaser.Text wouldn't render the text to its local canvas if you passed the text on the constructor and didn't add it to the display list. If a string is given it now updates the local canvas on creation.
* Signal.removeAll would ignore the context parameter and remove all bindings regardless (thanks @alect#1168)
* P2.Body.addCapsule didn't use to pass the radius value through pxm, but now does so you have to specify it in pixels, not meters.
### p2.js 0.6.0 Changes and New Features
* DistanceConstraint signature changed to take the new localAnchors.
* World.createDistanceConstraint signature changed to include new local anchors (thanks @rhmoller#1169)
* RevoluteConstraint signature changed to include worldPivot.
* P2.Body now uses the new Body.type value instead of Body.motionState, however as P2.Body already have a property called `type` we have left the `motionState` getter/setter in for now.
* World.enableBodySleeping has been removed and replaced with World.sleepMode.
* Phaser P2.Springs are now LinearSprings by default.

* Changed constructor of RevoluteConstraint. Now the local pivots are passed as options instead of direct arguments. See the constraints demo.
* Removed World.prototype.toJSON and .fromJSON.
* Removed properties .enableBodySleeping and .enableIslandSleeping from World instances. The enum .sleepMode can be used instead. See the sleep demo.
* Converted Spring to a base class for the new LinearSpring and RotationalSpring classes. LinearSpring can be used as the old Spring.
* Utils.ARRAY_TYPE can now be overridden by injecting a global called P2_ARRAY_TYPE. Support for GLMAT_ARRAY_TYPE has been removed.
#### Other changes
* Added flag .enableFrictionReduction to Narrowphase.
* Added RevoluteConstraint.prototype.setLimits.
* Added PrismaticConstraint.prototype.setLimits.

* Updated to Pixi.js 1.6.1 which fixes various issues such as IE9 Float32 defs and RenderTexture resizing and rendering.
* TypeScript definitions fixes and updates (thanks @clark-stevenson and @alvinsight)
* GameObjectFactory.spriteBatch now lets you specify `null` as a parameter for the parent and automatically adds the batch to `game.world` as a result. Also fixed jsdocs issues (@petarov #1000)
* Rebuilt the way items are polled for Pointer events (drag, click, move). Now faster and more efficient, especially when some items in the stack require pixel perfect checks.
* InputHandler.checkPointerOver now has a new `fastTest` parameter that forces a skips a pixel perfect check even if enabled.
* InputHandler.checkPointerDown now has a new `fastTest` parameter that forces a skips a pixel perfect check even if enabled.
* The key is now reported when failing to parse a Sprite Sheet (thanks @lucbloom#1026)
* An editorconfig has been added to the core repo. See http://editorconfig.org (thanks @codevinksy#1027)
* Keyboard.processKeyPress now checks if the Keyboard Input handler is disabled or not before processing the key callbacks.
* Physics.bounds now correctly matches World.bounds on system start (thanks @Dumtard#1028)
* Game._codePaused is now set if the Game is manually paused. See discussion: http://www.html5gamedevs.com/topic/6719-codepaused-property/ (thanks @devinb83#1017)
### New Features
* ArrayList.setAll - sets the property to the given value on all members of the list.
* Sprite.loadTexture has a new optional `stopAnimation` boolean parameter which will halt the currently running animation (if any) after changing the texture (based on #1029).
* Animation.updateFrameData allows you to load a new FrameData object into an existing animation, even if currently running (based on #1029)
* AnimationManager.loadFrameData will now update all existing Animations to use the newly loaded FrameData (based on #1029)
* Sprite.loadTexture will store the `smoothed` property of the Sprite and re-apply it once the new texture is loaded.
* Group.checkAll allows you to check if the same property exists across all children of the Group and is set to the given value (thanks @codevinsky#1013)
* Group.checkProperty allows you to check if the property exists on the given child of the Group and is set to the value specified (thanks @codevinsky#1013)
* Phaser.Utils.setProperty will set an Objects property regardless of depth (thanks @codevinsky#1013)
* Phaser.Utils.setProperty will set an Objects property regardless of depth (thanks @codevinsky#1013)
* Phaser.Utils.getProperty will get an Objects property regardless of depth (thanks @codevinsky#1013)
* Debug.preUpdate was still being called in the Game Loop even if enableDebug was set to false (thanks @qdrj#995)
* Phaser.Physics.P2.Body.addPolygon didn't work with a flat array of numbers for the coordinates (thanks @petarov, fix #883)
* Added missing Loader.onPackComplete Signal (thanks @mjeffery#1007)
* QuadTree leveling - Rather than level++ which changes the current nodes level, the subnodes should get the current nodes level+1 (thanks @devinb83#1018)
* Prevented objects with pixel perfect checks from over-riding other higher priority ID items (#983)
* Group.create was not creating with p2 debug flag (thanks @Dumtard#1014)
* World.wrap when using the bounds of the object wouldn't adjust the bounds correctly, meaning wrapping outside the camera failed (thanks @jackrugile#1020)
* Pixi updated worldTransform from an Array to an Object and Phaser Image, BitmapText, Text and Graphics were still using array access to populate the world property, giving it incorrect results (thanks @alvinsight)
* If you add a Tween to the TweenManager and then immediately stop it, it will still exist in the TweenManager (thanks @gilangcp#1032)
* AnimationManager does not update currentFrame on play until second frame (thanks @Dumtard#1041)
* Animation now guards against _frameData being null (thanks @lucbloom#1033)
* Tilemap.swap now accurately swaps from A to B and from B to A (thanks @noidexe#1034)
* BitmapData.resize fixed to update the crop property too, resolves issues with images getting cut off with BitmapData.load.
* OrientationSprite fix as it's not using PIXI.TextureCache anymore (thanks @DarkDev- #1036)
* The PIXI.TextureCache global array is no longer used internally for storing Pixi Texture files. It's not actually a requirement of Pixi to use this and we were running into various issues with texture conflicts in DragonBones tests and issues with shared texture frames between Sprites. It meant we couldn't crop a sprite without cropping all instances unless we created a new texture frame at run-time, which as you can imagine is a huge overhead if you then want to crop an animated Sprite.
After talking with Mat at GoodBoyDigital about the issue it was his idea to just not use the TextureCache at all, and let each Sprite have its own frame. So this is the direction we've taken. We didn't save this for the 2.1 release as it doesn't actually alter the Phaser API at all, but it does change how things are working internally. So if you've got game code hooked directly into the `TextureCache` you need to be aware of this change before updating to 2.0.6.
* The way in which Sprite.crop works has been changed. It will now adjust the dimensions of the sprite itself, remaining at the sprites previous x/y coordinates. Please be aware of this if you use cropped sprites in your game. The change was worth it though as it's significantly more powerful as a result.
### Updates
* Merged Pixi 1.6.0 with Phaser - all of the lovely new Pixi features are in, like complex Graphics objects and masking.
* TypeScript definitions fixes and updates (thanks @clark-stevenson and @Phaiax)
* Documentation fixes (thanks @kay-is #941)
* BitmapData.draw can now also take a Phaser.Sprite, Phaser.Image or BitmapData object as a source type. As a result BitmapData.drawSprite is now depcreated.
* BitmapData.alphaMask can now also take a Phaser.Sprite, Phaser.Image or BitmapData object as a source type.
* BitmapData.alphaMask has 2 new optional parameters: sourceRect and maskRect to give more fine-grained control over where the source and mask are drawn and their size
* BitmapData.alphaMask 'mask' parameter is now optional, if not given it will use itself as the mask.
* BitmapData.alphaMask now calls BitmapData.update after running.
* BitmapData.draw now has two optional parameters: width and height, to let you stretch the image being drawn if needed.
* Group.destroy now removes any set filters (thanks @Jmaharman fix #844)
* RetroFont charsPerRow paramters is now optional. If not given it will take the image width and divide it by the characterWidth value.
* RetroFont now uses Phaser.scaleModes.NEAREST by default for its RenderTexture to preserve scaling.
* Loader.tilemap has renamed the `mapURL` parameter to `url` and `mapData` to `data` to keep it consistent with the other Loader methods.
* Loader.physics has renamed the `dataURL` parameter to `url` and `jsonData` to `data` to keep it consistent with the other Loader methods.
* Stage no longer creates the Phaser.Canvas object, but Game itself does in the setupRenderer method.
* Canvas.create has deprecated the noCocoon parameter as it's no longer required. The parameter is still in the signature, but no longer used in the method.
* Time.add allows you to add an existing Phaser.Timer to the timer pool (request #864)
* Emitter.start has a new parameter: forceQuantity which will force the quantity of a flow of particles to be the given value (request #853)
* Sound.pause will no longer fire a Sound.onStop signal, and the pause values are set before the onPause signal is dispatched (thanks @AnderbergE, fix #868)
* Swapped to using escaped Unicode characters for the console output.
* Frame.setTrim no longer modifies the Frame width and height values.
* AnimationParser doesn't populate the Pixi.TextureCache for every frame any longer. Each display object has its own texture property instead.
* Removed the cacheKey parameters from the AnimationParser methods as they're no longer used.
* Loader.isLoading is set to false if the filelist size is zero.
* Sound.externalNode has had the `input` property dropped from it, bringing it back in line with the AudioNode spec (thanks @villetou, #840)
* The StateManager has a preRenderCallback option, which checks for a preRender function existing on the State, but it was never called. Have decided to add this in, so the core Game loop now calls state.preRender right before the renderer runs (thanks @AnderbergE#869)
* Game.onBlur and Game.onFocus events are now dispatched regardless if Stage.disableVisibilityChange is true or false, so you can respond to these events without your game automatically pausing or resuming (#911)
* Image has been heavily refactored to make use of common code in Phaser.Sprite, cutting the file size down significantly.
* When using the non-minified version of Phaser it will throw a console.warn if you give an invalid texture key to a Sprite, Image or TileSprite (thanks @lucbloom, #990)
### CocoonJS Specific Updates
* Wrapped all touch, keyboard, mouse and fullscreen events that CocoonJS doesn't support in conditional checks to avoid Warnings.
* The SoundManager no longer requires a touch to unlock it, defaults to unlocked.
* Resolved issue where Cocoon won't render a scene in Canvas mode if there is only one Sprite/Image on it.
### New Features
* BitmapData.extract has a new parameter that lets you control if the destination BitmapData is resized before the pixels are copied.
* BitmapData.extract has 4 new parameters: r2, g2, b2, a2 which let you re-color the extract pixels as they are drawn to the new BitmapData.
* BitmapData.load will take a game object or string and resize the BitmapData to match it and then draw the pixels in.
* Keyboard.addCallbacks now has a new parameter for keypress event capture.
* Keyboard.pressEvent stores the most recent DOM keypress event.
* Keyboard.processKeyDown now runs the callback after all the objects have been created and/or updated.
* Keyboard.processKeyUp now runs the callback after all the objects have been created and/or updated.
* Phaser.Keyboard.lastChar will return the string value of the last key pressed.
* Phaser.Keyboard.lastKey will return the most recently pressed Key object.
* RetroFont.updateOffset allows you to modify the offsetX/Y values used by the font during rendering.
* ArcadePhysics.Body has a new boolean property `enable`. If `false` the body won't be checked for any collision or overlaps, or have its pre or post update methods called. Use this for easy toggling of physics bodies without having to destroy or re-create the Body object itself.
* BitmapData.addToWorld will create a new Phaser.Image object, assign the BitmapData to be its texture, add it to the world then return it.
* BitmapData.copyPixels now accepts a Sprite, Image, BitmapData, HTMLImage or string as its source.
* Loader.pack will allow you to load in a new Phaser Asset Pack JSON file. An Asset Pack is a specially structured file that allows you to define all assets for your game in an external file. The file can be split into sections, allowing you to control loading a specific set of files from it. An example JSON file can be found in the `resources\Asset Pack JSON Format` folder and examples of use in the Phaser Examples repository.
* Loader.totalQueuedPacks returns the number of Asset Packs in the queue.
* Loader.totalLoadedPacks returns the number of Asset Packs already loaded.
* Emitter.explode is a new short-cut for exploding a fixed quantity of particles at once.
* Emitter.flow is a new short-cut for creating a flow of particles based on the given frequency.
* Sprite.crop (and Image.crop) has been completely overhauled. You can now crop animated sprites (sprite sheet and texture atlas), you can define the x/y crop offset and the crop rectangle is exposed in the Sprite.cropRect property.
* Sprite.updateCrop is available if you wish to update an externally referenced crop rectangle.
* Sprites and Images now have their own textures objects, they are no longer references to those stored in the global Pixi.TextureCache. This allows you to redefine the texture frame dynamically without messing up any other Sprites in your game, such as via cropping. They still share global Base Textures, so image references are kept to a minimum.
* Sprite.resetFrame will revert the Sprites texture frame back to its defaults dimensions. This is called when you call Sprite.crop with no rectangle, to reset the crop effect, but can be userful in other situations so we've left it as a public method.
* TilemapLayers can now be used with an unbounded camera (a camera that can move beyond the world boundaries). Currently, when an unbounded camera moves outside of the world, tilemaps start acting weird because they only render themselves strictly within the world limits. With this change, the tilemap will continue scrolling and show empty space beyond its edge (thanks @jotson#851)
* TilemapLayer.wrap property - if true the map is rendered as if it is on the surface of a toroid (donut) instead of a plane. This allows for games that seamlessly scroll from one edge to the opposite edge of the world without noticing the transition. Note that the World size must match the Map size (thanks @jotson#851)
* Added PlayStation 3 controller button mappings to Phaser.Gamepad (thanks @wayfu)
* GamepadButton.destroy method added. Called automatically by SinglePad when a controller is disconnected.
* Added Math.factorial (thanks @alvinsight, #940)
* Full Mouse Wheel support added, with new constants and callbacks for mouse wheel movement (thanks @woutercommandeur, #959)
* A Phaser version of the Pixi PixelateFilter was added by @paperkettle#939)
* TileMap.setPreventRecalculate allows you to turn on / off the recalculation of tile faces for tile collision, which is handy when modifying large portions of a map to avoid slow-down (thanks @sivael, #951)
* Group.add has a new optional boolean parameter: `silent`. If set to `true` the child will not dispatch its `onAddedToGroup` event.
* Group.addAt has a new optional boolean parameter: `silent`. If set to `true` the child will not dispatch its `onAddedToGroup` event.
* Group.remove has a new optional boolean parameter: `silent`. If set to `true` the child will not dispatch its `onRemovedFromGroup` event.
* Group.removeBetween has a new optional boolean parameter: `silent`. If set to `true` the children will not dispatch their `onRemovedFromGroup` events.
* Group.removeAll has a new optional boolean parameter: `silent`. If set to `true` the children will not dispatch their `onRemovedFromGroup` events.
* Internal child movements in Group (such as bringToTop) now uses the new `silent` parameter to avoid the child emitting incorrect Group addition and deletion events.
* Camera.updateTarget has had a make-over and now is a lot smoother under certain conditions (thanks @tjkopena, fix #966)
* Signal.removeAll now has a new `context` parameter. If specified only listeners matching the given context are removed (thanks @lucbloom for the idea, #880)
* Animation.next will advance to the next frame in the animation, even if it's not currently playing. You can optionally define the number of frames to advance, but the default is 1. This is also aliased from the AnimationManager, so you can do `Sprite.animations.next()`.
* Animation.previous will rewind to the previous frame in the animation, even if it's not currently playing. You can optionally define the number of frames to rewind, but the default is 1. This is also aliased from the AnimationManager, so you can do `Sprite.animations.previous()`.
* You can now debug render Ninja Physics AABB and Circle objects (thanks @psalaets, #972)
* Phaser.Utils.mixin will mix the source object into the destination object, returning the newly modified destination object.
* You can now use `game.add.plugin` from the GameObjectFactory (thanks @alvinsight, #978)
* Color.getWebRGB will now accept either an Object or numeric color value.
* Rectangle.randomX will return a random value located within the horizontal bounds of the Rectangle.
* Rectangle.randomY will return a random value located within the vertical bounds of the Rectangle.
* Using a Game configuration object you can now specify the value of the `preserveDrawingBuffer` flag for the WebGL renderer. By default this is disabled for performance reasons. But if you need to be able to take screen shots of your WebGL games using toDataUrl on the game canvas then you'll need to set this to `true` (#987)
* Added options to disable horizontal and vertical world wrapping individually (thanks @jackrugile, #988)
* You can now prevent the Debug class from being created or booted by using the Game configuration setting: `enableDebug`. By default it is `true`, set to `false` to prevent the class from being created. Please note you are responsible for checking if this class exists before calling it, but you can do that via `if (game.debug) { ... }` (request #984)
### Bug Fixes
* Sprite.alive property now explicitly defined on the Sprite prototype (thanks @lewster32, #841)
* BitmapData.resize now properly updates the baseTexture and texture dimensions.
* Fixed Gamepad issue that incorrectly checked non-webkit prefix gamepads.
* Phaser.RenderTexture incorrectly passed the scaleMode to Pixi.RenderTexture, causing the renderer to error.
* Sprite animation data wasn't reset when going from a sprite sheet to a single frame in Sprite.loadTexture (thanks @lucbloom, fix #850)
* Timer.ms would report the game time ms value if the Timer hadn't yet been started, instead of 0.
* Timer.seconds would report the game time value if the Timer hadn't yet been started, instead of 0.
* A Canvas style set from a game config object used an incorrect property (thanks @TatumCreative, fix #861)
* Phaser.Line.intersectsPoints fixed for floating point inaccuracy (thanks @woutercommandeur, fix #865 and #937)
* Sound.destroy(true) would call remove on the SoundManager, which in turn would throw a TypeError as it tried to remove the sound events twice (thanks @AnderbergE, fix #874)
* When creating a Sprite or Image using a texture atlas it would set the frame twice, once in loadTexture and once when the initial frame is set. This has been reduced down to just a single setting now.
* BitmapData.getPixel fix for pixels with zero red value (thanks @lstor fix #894)
* If you call ArcadePhysics.collide on a Sprite vs. a Tilemap and provide a custom processCallback, the result was being ignored and the sprite was being separated regardless (thanks @aivins fix #891#890)
* ArcadePhysics.Body.setSize if you set offset x/y values previously and then passed zero values they would be ignored (thanks @casensiom fix #889)
* Sound.onDecoded signal was never dispatched (thanks @j0hnskot, #906)
* stopFullScreen has been changed to run against document instead of the canvas since the cancelFullScreen method is created on the document (thanks @j0hnskot, #863)
* Calling reset on Sprite with a P2 body can result in body.data.world == null.
Calling addToWorld() would previously not check the _toRemove array, which could, if the timing were right, result in a Sprite being revived but then removed from the P2 World -- the result of this being the Sprites data would be in a mixed state causing it to appear visually but not function in the world (thanks @jonkelling, fix #917#925)
* Input.SinglePad was fixed so that the rawpad button array supports Windows and Linux (thank @renatodarrigo, fix #958)
* Key.duration wasn't set to zero after a Key.reset (thanks @DrHackenstein, #932)
* Device.mobileSafari was no longer detecting Mobile Safari, now fixed (thanks @Zammy, #927)
* Rectangle.right when set would set the new width to be Rectangle.x + the value given. However the value given should be a new Right coordinate, so the width calculation has been adjusted to compensate (thanks @cryptonomicon, #849)
* Calling Tween.stop from inside a Tween update callback would still cause the tween onComplete event to fire (thanks @eguneys, #924)
* Group.bringToTop (and consequently Sprite.bringToTop) no longer removes the child from the InputManager if enabled (thanks @BinaryMoon, fix #928)
* Group.sendToBack (and consequently Sprite.sendToBack) no longer removes the child from the InputManager if enabled.
* When adding a new Animation to a Sprite it would incorrectly reset the current Sprite frame to the first frame of the animation sequence, it is now left un-touched until you call `play` on the animation.
* Tween.from now returns a reference to the tweened object in the same way that Tween.to does (thanks @b-ely, fix #976)
* Re-ordered the parameters of Phaser.Physics.Arcade.Body.render which is used by Debug.body so it matches correctly (thanks @psalaets, #971#970)
* Removed hasOwnProperty check from Tween.from because it breaks on extended or inherited Game Objects.

* ArcadePhysics.collideSpriteVsGroup checks if Sprite has a body before carrying on, now safely skips sub-groups or other non-Sprite group children.
* Group.remove now checks the child to see if it's a member of the root Group before removing it, otherwise Pixi throws an Error.
* The Emitter no longer checks if minParticleScale = maxParticleScale for the scale check, allowing for fixed scale particles again.
* The PIXI.AbstractFilter is now included in the Phaser Pixi build by default, allowing for easier use of external Pixi Filters.
* All Game Objects have a new property: destroyPhase (boolean) which is true if the object is in the process of being destroyed, otherwise false.
* If Tween.yoyo was true but repeat was 0 then it wouldn't yoyo. Now if yoyo is set, but not repeat, the repeat count gets set to 1 (thanks @hilts-vaughan, fix #744)
* RandomDataGenerator.integerInRange uses a new method of rounding the value to an integer to avoid distribution probability issues (thanks PhaserFan)

* Keyboard.reset has a new `hard` parameter which controls the severity of the reset. A soft reset doesn't remove any callbacks or event listeners.
* Key.reset has a new `hard` parameter which controls the severity of the reset. A soft reset doesn't remove any callbacks or event listeners.
* InputManager.resetLocked - If the Input Manager has been reset locked then all calls made to InputManager.reset, such as from a State change, are ignored.
* Group.resetCursor will reset the Group cursor back to the start of the group, or to the given index value.
* World.wrap will take a game object and if its x/y coordinates fall outside of the world bounds it will be repositioned on the opposite side, for a wrap-around effect.
* Device.support32bit is a new boolean that sets if the context supports 32bit pixel manipulation using array buffer views or not.
* P2.World now has its own pause and resume methods, so you can pause the physics simulation independent of your game (thanks @georgiee)

* P2.Body.loadPolygon has been updated to correct center of mass issues (thanks @georgiee, fix #749)
* Game checks if window.console exists before using it (should fix IE9 issues when dev tools are closed), however it is still used deeper in Pixi.
* Masks now work when used in RenderTextures / CacheAsBitmap and Filters (pixi.js update)
* Stroked text sometimes got clipped (pixi.js update)
* Polygon.contains now works for coordinates to the left of the polygon (thanks @vilcans, fix #766)
* Game pause/resume could incorrectly increment paused Timers (thanks @georgiee, fix #759)
* Animations resuming from a pause no longer skip frames (thanks @merixstudio, fix #730)
* Tilemap.fill would throw an error if called on a blank tilemap full of null values (thanks @DrHackenstein, fix #761)
* LoaderParser.bitmapFont updated so xml parsing works properly on IE9 (thanks @georgiee)
* Sounds that had been paused via game code would un-mute if the game paused and resumed.
* CSV Tilemap tiles would incorrectly set the Tile layer reference, causing collision to fail (thanks @Chapelin, fix #692)
The following issues were fixed in 2.0.4 approx. 1 hour after official release:
* ScaleManager seeds _check private var with null to avoid later comparison check (thanks @jflowers45, fix #782)
* P2.Body.applyForce should have used pxmi instead of pxm (thanks @Trufi, fix #776)
* P2 fixed creation of RevoluteConstraint by passing maxForce in the options (thanks @woutercommandeur, fix #783)
* Tilemap.getTile and getTileXY used to return `null` in 2.0.3 but returned a Tile object in 2.0.4 (with an index of -1), they now return `null` again.
* Updated to [Pixi.js 1.5.2](https://github.com/GoodBoyDigital/pixi.js/releases/tag/v1.5.2)
* Updated to [p2.js 0.5.0](https://github.com/schteppe/p2.js/releases/tag/v0.5.0)

* Further TypeScript defs tweaks (thanks @clark-stevenson)
* Lowered the default size of SpriteBatch from 10000 to 2000 as this yields faster results on mobile (pixi.js update)
* Fix for 'jagged' strokes on custom fonts (thanks @nickryall, #677)
* The State.update function (and thus the update of any sub-classed Sprites or other objects) is now called before Stage, Tweens, Sound, Input, etc (#662)
* The Phaser jshint process is now running on Travis (thanks @xtian, #656)
* The Phaser Gruntfile is now split up into option tasks (thanks @xtian, #638)
* Key.reset now clears any callbacks associated with the onDown and onUp events and nulls the onHoldCallback if set. Key.reset is called by Keyboard.reset when changing state.
* If you pass `null` to Tilemap.putTile as the tile parameter it will pass the call over to Tilemap.removeTile.
* TypeScript definitions updated for latest changes (thanks @clark-stevenson)
* Keyboard.stop nulls the function references after removing the event listeners (thanks @bmceldowney, #691)
* Tilemap.hasTile allows for multi-layer type parameter (thanks @Raeven0, #680)
* Grunt update to dev dependencies (thanks @xtian, #695)
* Emitter now emits Phaser.Particle objects instead of Phaser.Sprites, which can be extended as required.
* Emitter has had various local properties removed that were already declared in Phaser.Group which it extends.
* PluginManager parent parameter removed as it's redundant. Also most core functions tidied up and jsdocs fixed.
* p2.World.defaultRestitution has been deprecated and is now p2.World.restitution.
* p2.World.defaultFriction has been deprecated and is now p2.World.friction.
* p2.World now uses 4 bodies for the world boundaries, rather than 1 body with 4 shapes. This stops the bounds triggering narrowphase with every single body in the world.
* p2.World bounds are now included in the callback events such as beginContact and impact events.
* Thanks to @STuFF the Classes drop-down list in the API docs now indents the sub-classes.
* Added ability to retrieve a single p2 fixture from the cache (thanks @georgiee, #674)
* Timers can now have a start delay value (thanks @georgiee, #660)
* CacheAsBitmap added to Display Object, so works for Sprite, Image, Button. Allows you to cache complex display hierarchies for speed.

* Added generateTexture function to display objects. Create a texture from the current object display hierarchy for use as a texture elsewhere.
* Added optional FilterArea to display object (for optimisation)
* Graphics chaining functions.
* Added Pointer.positionUp which records the last point at which the pointer left the screen (thanks @Cryszon, #676)
* Phaser.Point.centroid static function added to calculate the centroid or midpoint of an array of points (thanks @lewster32, #675)
* SoundManager.remove(sound) now lets you remove a sound from the SoundManager, destroying it in the process.
* Sound.destroy will remove a sound and all local references it holds, optionally removing itself from the SoundManager as well.
* SoundManager.removeByKey(key) will remove all sounds from the SoundManager that have a key matching the given value.
* ArcadePhysics.Body.hitTest(x, y) will return a boolean based on if the given world coordinate are within the Body or not.
* StateManager.restart allows you to quickly restart the *current* state, optionally clearing the world and cache.
* Tilemap.removeTile(x, y, layer) lets you remove the tile at the given coordinates and updates the collision data.

* Emitter now has minParticleAlpha and maxParticleAlpha values for setting a random alpha on emitted particles.
* Emitter.particleAnchor allows you to control the anchor of emitted Particles. Defaults to 0.5 (same as before) but now under your control.
* Emitter.setAlpha allows you to quickly set the min and max alpha values.
* Emitter.setScale allows you to quickly set the min and max scale values.
* Emitter.blendMode lets you set the blendMode of any emitted Particle (needs a browser that supports canvas blend modes)
* Group.customSort allows you to sort the Group children based on your own sort function.
* Emitter.setScale has a new 'rate' parameter which allows particles to change in scale over time, using any Easing value or timescale.
* Emitter.setScale now allows you to scale the x and y axis of the particles independently.
* Emitter.setAlpha has a new 'rate' parameter which allows particles to change alpha over time, using any Easing value or timescale.
* Emitter.bringToTop and Emitter.sendToBack are booleans that let you optionally set the display order of the Particle when emitted.
* Emitter now calls the Phaser.Particle.onEmit function, which is left empty for you to override and add in custom behaviours.
* p2.World has a new contactMaterial property, which can be configured like a normal P2 Contact Material and is applied when two bodies hit that don't have defined materials.
* Group.remove has a new 'destroy' parameter (false by default), which will optionally call destroy on the item removed from the Group.
* Group.removeAll has a new 'destroy' parameter (false by default), which will optionally call destroy on the items removed from the Group.
* Group.removeBetween has a new 'destroy' parameter (false by default), which will optionally call destroy on the items removed from the Group.
*@georgiee created a new P2.FixtureList class to allow easy access the fixtures of a created P2 Body:
This is especially useful in combination with PhysicsEditor and P2.Body#addPhaserPolygon.
You can configure your whole collision grouping in PhysicsEditor and then you can later change the mask bits easily with this class. You can also access parts (groups) and named fixtures by a group index or a fixture key - both properties can be set in PhysicsEditor with the custom phaser exporter.
Use cases:
* Configure collision bits in PhysicsEditor and you want to change them later.
* Place a sensor in your fixture and access this single fixture later (to disable temporarily)
* Create a small body with threes fixtures (circle, circle + polygon/convex). Now you want that the polygon part to behave like rubber and assign a bouncing (restitution > 1) material. Assign a fixture key in PhysicsEditor and access the fixture like this. (see the image for the fixture I described)
* If you inputEnable = false a gameobject you couldn't re-enable it again using inputEnable = true, only directly via the handler (thanks @nickrall, fix #673)
* Fixed setTexture bug with TilingSprite (pixi.js 1.5.2 bug fix)

* Added properties .allowSleep, .sleepState, .sleepSpeedLimit, .sleepTimeLimit, .lastTimeSleepy as well as methods .sleep, .wakeUp and .sleepTick to Body.
* Updated Device.isConsoleOpen as it no longer works in Chrome. Revised code and documentation accordingly (fix #593)
* Removed State.destroy empty method and replaced with State.shutdown, as that is what the StateManager expects (fix #586)
* P2.removeBody will check if the body is part of the world before removing, this avoids a TypeError from the p2 layer.
* Tilemap.createFromObjects has a new parameter: adjustY, which is true by default. Because Tiled uses a bottom-left coordinate system Phaser used to set the Sprite anchor to 0,1 to compensate. If adjustY is true it now reduces the y value by the object height instead.
* Swapped the order of the _pollGamepads gamepads check, to stop the Chrome 'webkitGamepads is deprecated' error in the console.
* Lots of TypeScript definitions updates (thanks as always to clark for these)
* Removed Device.patchAndroidClearRectBug as it's no longer used internally.
* Math.wrapAngle now supports radians (thanks Cryszon, #597)
* Group.replace will now return the old child, the one that was replaced in the Group.
* Group.destroy has a new parameter: `soft`. A soft destruction won't remove the Group from its parent or null game references. Default is `false`.
* InputHandler.validForInput is a new method that checks if the handler and its owner should be considered for Pointer input handling or not.
* ArcadePhysics.Body now checks the ArcadePhysics.World bounds, not the game bounds.
* ArcadePhysics.Body has reverted to the 1.1.3 method of preUpdate, so you can now position sprites with x/y, drag them, etc, regardless of the Body.moves flag (issue #606)
* ArcadePhysics.World now has setBounds and setBoundsToWorld methods, which are called automatically on world resizing.
* ArcadePhysics.Body no longer sets the offset to match the anchor.
* The StateManager is now responsible for clearing down input, timers, tweens, physics, camera and the World display list.
* Removed the use of Int16Array from all Game Objects, swapped for standard Array. Phaser now runs on Android 2.x and IE9 again (fix #590)
* When creating a Sprite (via Group.create or directly) with exists = false and a P2 body, the body is not added to the world.
* Every Input class now checks to see if it has already been started. If so it doesn't add the listeners again unless they have been nulled.
* Lots of fixes to the TypeScript definitions file (thanks as always to clark-stevenson for his tireless work on these)
* Emitters now bring the particle they are about to emit to the top of the Group before doing so. Avoids particles hidden behind others.
* ArcadePhysics.Body.setSize corrected to take the parameters as positive, not negative values.
* ArcadePhysics.World.seperate will now check gravity totals to determine separation order. You can set World.forceX to true to always separate on X first and skip this check.
* TileSprites now emit outOfBounds and enterBounds events accordingly.
* You can now create multiple blank layers in a Tilemap.
* Device.getUserMedia boolean added, useful if you need access to the webcam or microphone.
* Math.removeRandom allows you to remove (and return) a random object from an array.
* ArcadePhysics.World now has a checkCollision object which can be used to toggle collision against the 4 walls of its bounds.
* Sprite.events.onEnterBounds added. This is dispatched if the Sprite leaves the bounds but then returns. The opposite of onOutOfBounds.
* Timer.removeAll will remove and clear down all events, but keeps the Timer running.
* Group.setAllChildren recursively checks if its children are Groups, and if so recursively applies the value to their children as well (feature #589)
* Time.deltaCap lets you set a cap for the delta timer. It defaults to zero (which is disabled). If you use ArcadePhysics it gets set to 0.2, but you can modify as needed.
* ArcadePhysics.Body has a deltaMax object, which allows you to cap the delta applied to the position to +- this value.
* ArcadePhysics.Body now checks the Sprite scale automatically and adjusts the body size accordingly (fix #608)
* Emitter.particleClass can now be set to any object that extends Phaser.Sprite, which will be emitted instead of a regular Sprite.
* There is a brand new PhysicsEditor export script specifically for Phaser (in the resources folder), and new p2 polygon parsing functions thanks to georgiee.
There is an extensive [Migration Guide](https://github.com/photonstorm/phaser/blob/master/resources/Migration%20Guide.md) available for those converting from Phaser 1.x to 2.x. In the guide we detail the API breaking changes and approach to our new physics system.
* Phaser.Image is a brand new display object perfect for logos, backgrounds, etc. You can scale, rotate, tint, blend an get input events from an Image, but it has no animation or physics body.
* You can now use the hitArea property on Sprites and Image objects. hitArea can be a geometry object (Rectangle, Circle, Polygon, Ellipse) and is used in pointerOver checks.
* InputManager.getLocalPosition(displayObject, pointer, output) will return the local coordinates of the specified displayObject and pointer.
* InputManager.hitTest will test for pointer hits against a Sprite/Image, its hitArea (if set) or any of its children.
* Text has lots of new methods to help style it: Text.fill, Text.align, Text.stroke, etc.
* Text now works happily with font names with spaces in them.
* Text.setShadow applies a drop shadow to the Text being rendered. Control the x, y, color and blur.
* Text.lineSpacing allows you to set additional spacing between each line that is rendered.
* Text.inputEnabled allows you to enable all input events over Text objects: dragging, clicking, etc - anything that works on a Sprite works on Text now too.
* Phaser.Ellipse added. A fully compatible port of the PIXI.Ellipse class, can be used in Sprite/Image hitArea tests.
* Phaser.Polygon added. A fully compatible port of the PIXI.Polygon class, can be used in Sprite/Image hitArea tests.
* InputHandler.pixelPerfectOver - performs a pixel perfect check to see if any pointer is over the current object (warning: very expensive!)
* InputHandler.pixelPerfectClick - performs a pixel perfect check but only when the pointer touches/clicks on the current object.
* TileSprite can now use a frame from a texture atlas or a sprite sheet.
* TileSprites can now be animated. See new example :)
* TileSprites have a new method: autoScroll(x, y) which sets an automatic scroll running (until stopped with TileSprite.stopScroll).
* BitmapText now uses the new XML parser which should work under CocoonJS without clashes.
* BitmapText signature changed so you can support fonts with spaces in their names.
* Loader.bitmapFont now has 2 extra parameters: xSpacing and ySpacing. These allow you to add extra spacing to each letter or line of the font.
* Added the new RetroFont class. This is for rendering fixed-width bitmap fonts into an Image object. It's a texture you can apply to a Sprite/Image.
* Added Cache.updateFrameData which is really useful for swapping FrameData blocks in the cache.
* Loader.physics now lets you load Lime + Corona JSON Physics data, which can be used with Body.loadPolygon and Body.loadData.
* Cache.addPhysicsData and Cache.getPhysicsData allow you to store parsed JSON physics data in the cache, for sharing between Bodies.
* fixedToCamera now works across all display objects. When enabled it will fix at its current x/y coordinate, but can be changed via cameraOffset.
* fixedToCamrea now works for Groups as well :) You can fix a Group to the camera and it will influence its children.
* Tilemap.createCollisionObjects will parse Tiled data for objectgroups and convert polyline instances into physics objects you can collide with in the world.
* Loader can now load JSON files specifically (game.load.json) and they are parsed and stored in the Game.Cache. Retrieve with game.cache.getJSON(key).
* TileSprites can now receive full Input events, dragging, etc and be positioned in-world and fixed to cameras.
* The StateManager now looks for a function called 'resumed' which is called when a game un-pauses.
* Key.onHold added. This event is dispatched every time the browser sends a keydown event and the key is already being held down.
* Stage.smoothed allows you to set if sprites will be smoothed when rendered. Set to false if you're using pixel art in your game. Default is true. Works in Canvas and WebGL.
* Sprite.smoothed and Image.smoothed allows you to set per-Sprite smoothing, perfect if you just want to keep a few sprites smoothed (or not)
* StateManager.start can now have as many parameters as you like. The order is: start(key, clearWorld, clearCache, ...) - they are passed to State.init() (NOT create!)
* Loader.script now has callback (and callbackContext) parameters, so you can specify a function to run once the JS has been injected into the body.
* Phaser.Timer.stop has a new parameter: clearEvents (default true), if true all the events in Timer will be cleared, otherwise they will remain (fixes #383)
* All GameObjects now have a 'destroyChildren' boolean as a parameter to their destroy method. It's default is true and the value propogates down its children.
* Pixi GrayFilter ported over (thanks nickryall #404)
* Animation.speed added. You can now change the animation speed on the fly, without re-starting the animation (feature request #458)
* Brand new Grunt task - creates each core library as its own file and a combined phaser.js.
* New build script now cleanly splits Phaser, Pixi and p2 so they are each UMD wrapped and each available in the global scope (now more requireJS friendly!).
* phaser-no-libs.js allows you to use your own version of p2.js or pixi.js with Phaser. Warning: This is totally unsupported. If you hit bugs, you fix them yourself.
* Group.sendToBottom(child) is the handy opposite of Group.bringToTop()
* Group.moveUp(child) will move a child up the display list, swapping with the child above it.
* Group.moveDown(child) will move a child down the display list, swapping with the child below it.
* Device.windowsPhone is now tested for.
* The Debug panel now works in WebGL mode. Pay attention to the warning at the top of the Debug docs (feature request #499)
* You can now create blank Tilemaps and then populate them with data later.
* A single Animation object now has 3 new events: onStart, onLoop and onComplete.
* Animation.loopCount holds the number of times the animation has looped since it last started.
* Tween.generateData(frameRate) allows you to generate tween data into an array, which can then be used however you wish (see new examples)
* Group.xy(index, x, y) allows you to set the x and y coordinates of a Group child at the given index.
* Group.reverse() reverses the display order of all children in the Group.
* Tweens are now bound to their own TweenManager, not always the global game one. So you can create your own managers now (for you clark :)
* ScaleManager.fullScreenTarget allows you to change the DOM element that the fullscreen API is called on (feature request #526)
* Merged Georges p2 BodyDebug and reformatted for jshint pass. Looks awesome :)
* ArcadePhysics.Body has a new gravityScale property, which is a modifier multiplied against the world gravity value on a Body.
* Line.coordinatesOnLine will return all coordinates on the line using Bresenhams line algorithm.
* Line now has x, y, width, height, top, bottom, left and right properties, so you can effectively get its bounds.
* TilemapLayer.getRayCastTiles will let you get all tiles that hit the given line for further processing.
* Massive thanks to clark-stevenson for doing an amazing job update the TypeScript definitions file.
* Debug.renderRectangle has a new parameter: filled. If true it renders as with fillRect, if false strokeRect.
* Phaser.AnimationParser now sets the trimmed data directly for Pixi Texture frames. Tested across JSON Hash, JSON Data, Sprite Sheet and XML.
* Game.add.renderTexture now has the addToCache parameter. If set the texture will be stored in Game.Cache and can be retrieved with Cache.getTexture(key).
* Game.add.bitmapData now has the addToCache parameter. If set the texture will be stored in Game.Cache and can be retrieved with Cache.getBitmapData(key).
* The InputManager now sets the canvas style cursor to 'inherit' instead of 'default'.
* World.reset now calls Camera.reset which sends the camera back to 0,0 and un-follows any object it may have been tracking.
* Added hostname: '*' to the grunt-connect in Gruntfile.js (fixes #426)
* Device, Canvas and GamePad classes all updated for better CocoonJS support (thanks Videlais)
* BitmapData.alphaMask will draw the given image onto a BitmapData using an image as an alpha mask.
* The new GameObjectCreator (which you access via game.make or State.make) lets you easily create an object but NOT add it to the display list.
* TilemapParser will now throw a warning if the tileset image isn't the right size for the tile dimensions.
* We now force IE11 into Canvas mode to avoid a Pixi bug with pre-multiplied alpha. Will remove once that is fixed, sorry, but it's better than no game at all, right? :(
* Loader.setPreloadSprite() will now set sprite.visible = true once the crop has been applied. Should help avoid issues (#430) on super-slow connections.
* Updated the way the page visibility is checked, should now be more compatible across more browsers.
* Phaser.Input.Key.isUp now defaults to 'true', as does GamepadButton.isUp (#474)
* Vastly improved visibility API support + pageshow/pagehide + focus/blur. Working across Chrome, IE, Firefox, iOS, Android (also fixes #161)
* Pausing the game will now mute audio and resuming will un-mute, unless it was muted via the game (fixes #439)
* ScaleManager has 2 new events: ScaleManager.enterFullScreen and ScaleManager.leaveFullScreen, so you can respond to fullscreen changes directly.
* RandomDataGenerator.integerInRange(min, max) now includes both `min` and `max` within its range (#501)
* Tween no longer copies all the object properties into the `_valuesStart` object on creation.
* Completely empty Tilemaps can now be created. This allows for dynamic map generation at runtime.
* Keyboard.event now stores the most recent DOM keyboard event.
* Animation.stop has a new parameter: dispatchComplete. If true it'll dispatch an Animation.onComplete event.
* TileSprites now have a physics body property and call it in the pre and post updates. As with all physics bodies it's null by default.
* json is now the default tilemap format when not defined (thanks RyanDansie, #528)
* The Particle Emitter now remembers the frames given to it and resets it when a new particle is emitted.
* Game.focusLoss and focusGain methods and onBlur and onFocus Signals added, allowing for more fine-grained control over game pause vs. focus loss.
* Explicitly paused Timer continues if you un-focus and focus the browser window (thanks georgiee)
* Added TimerEvent.pendingDelete and checks in Timer.update, so that removing an event in a callback no longer throws an exception (thanks georgiee)
* Fixed TypeScript defs on lines 1741-1748 (thanks wombatbuddy)
* Previously if you used Sprite.crop() it would crop all Sprites that shared the same base image. It now takes a local copy of the texture data and crops just that.
* Tilemap had the wrong @method signatures so most were missing from the docs.
* Fixed bug where changing State would cause the camera to not reset if it was following an object.
* Tile had 2 properties (callback and callbackContext) that were never assigned, updated to use the proper names (thanks ratkingsimon)
* Fixed an error that would occur if you used InputHandler.onInputUp and the Sprite destroys itself during the event.
* Fixed bug in Math.angleBetween where it was using the coordinates in the wrong order.
* Previously using a Pixel Perfect check didn't work if the Sprite was rotated or had a non-zero anchor point, now works under all conditions + atlas frames.
* If pixelPerfect Input Sprites overlapped each other the pixel check wasn't taken into consieration in the Pointer move method.
* Updated Input.Mouse to use event.button not event.which, so the const reference from input.mouse.button is correct (thanks grimor)
* Text that was fixedToCamera would 'jitter' if the world scrolled. Now works as expected across all fixed objects.
* Fixed a bug where Sound.play wouldn't pick-up the local loop setting if not specified in the parameter.
* Active animations now monitor if the game pauses, and resume normally when the game un-pauses (fixes #179)
* Swapping between tabs will now pause the game correctly on mobile browsers (iOS7+)
* Swapping between tabs will pause and resume tweens correctly, allowing their onComplete events to still fire (fixes #292)
* Fullscreen mode now uses window.outerWidth/Height when using EXACT_FIT as the scale mode, which fixes input coordinate errors (fixes #232)
* Fullscreen mode now works in Internet Explorer and uses the new fullscreen non-prefix call.
* Fixed TilemapParser - would spit out a tileset warning if margin/spacing were set (fix #485, thanks Cybolic)
* AnimationParser.spriteSheet wasn't taking the margin or spacing into account when calculating the numbers of sprites per row/column, nor was it allowing for extra power-of-two padding at the end (fix #482, thanks yig)
* AnimationManager.add documentation said that 'frames' could be null, but the code couldn't handle this so it defaults to an empty array if none given (thanks yig)
* Fixed issue stopping SoundManager.volume from working correctly on a global volume basis (fixes #488)
* Phaser.Timer will no longer create negative ticks during game boot, no matter how small the Timer delay is (fixes #366)
* Phaser.Timer will no longer resume if it was previously paused and the game loses focus and then resumes (fixes #383)
* Tweens now resume correctly if the game pauses (focus loss) while they are paused.
* Tweens don't double pause if they were already paused and the game pauses.
* Buttons are now cleanly destroyed if part of a Group without leaving their InputHandler running.
* You can now safely destroy a Group and the 'destroyChildren' boolean will propogate fully down the display list.
* Calling destroy on an already destroyed object would throw a run-time error. Now checked for and aborted.
* Calling destroy while in an Input Event callback now works for either the parent Group or the calling object itself.
* Loader.replaceInFileList wouldn't over-write the previous entry correctly, which caused the Loader.image overwrite parameter to fail (thanks basoko, fixes #493)
* If the game was set to NO_SCALE and you swapped orientation, it would pause and resize, then fail to resize when you swapped back (thanks starnut, fixes #258)
* Device no longer things a Windows Phone or Windows Tablet are desktop devices (thanks wombatbuddy, fixes #506)
* Sound.onMarkerComplete event is now dispatched when a marker stops. See Sound.onLoop for a looping marker event (thanks registered99, fixes #500)
* Events.onInputUp would be dispatched twice if the Sprite had drag enabled, now only dispatched once (thanks Overbryd, fixes #502)
* You can now load in CSV Tilemaps again and they get created properly (fixes #391)
* Tilemap.putTile can now insert a tile into a null/blank area of the map (before it could only replace existing tiles)
* Tilemap.putTile now correctly re-calculates the collision data based on the new collideIndexes array (fixes #371)
* Circle.circumferencePoint using the asDegrees parameter would apply degToRad instead of radToDeg (thanks Ziriax, fixes #509)
* InputHandler.enableSnap now correctly assigns the snap offset parameters (fixes #515)
* Objects that are 'fixedToCamera' are now still correctly placed even if the camera is scaled (#512)
* Changed the define function calls to use named modules, allows pixi, phaser and p2 to reside in 1 file and still be located by requirejs (thanks brejep, #531)
* Cache.destroy fixed to clear up properly (thanks Dumtard, #537)
* Loader.tileset has been removed as it's no longer required, this was as part of the Tilemap system overhaul.
* TilemapLayers are now created via the Tilemap object itself: map.createLayer(x, y, width, height, tileset, layer, group) and no longer via the GameObjectFactory.
* Tilemap.createFromObjects can now turn a bunch of Tiled objects into Sprites in one single call, and copies across all properties as well.
* Tween.onStartCallback and onCompleteCallback have been removed to avoid confusion. You should use the onStart, onLoop and onComplete events instead.
* Button.forceOut default value has changed from true to false, so Buttons will revert to an Up state (if set) when pressed and released.
* The way the collision process callback works has changed significantly and now works as originally intended.
* The World level quadtree is no longer created, they are now built and ripped down each time you collide a Group, this helps collision accuracy.
* A SAT system has been integrated for Body collision and separation.
* Bodies are no longer added to a world quadtree, so have had all of their quadtree properties removed such as skipQuadtree, quadTreeIndex, etc.
* Body.drag has been removed. Please use the new Body.linearDamping value instead (which is a number value, not a Point object)
* Body.embedded and Body.wasTouching have been removed as they are no longer required.
* Body.customSeparateX/Y have been removed as you should now use Body.customSeparateCallback.
* Body.maxVelocity defaults have been removed from 10,000 to 2000.
* Body.customSeparateCallback allows you to set your own callback when two Bodies need to separate rather than using the built-in method.
* Body.collideCallback allows you to set a callback that is fired whenever the Body is hit on any of its active faces.
* Body.allowCollision has been renamed to Body.checkCollision.
* Body.rebound is a boolean that controls if a body will exchange velocity on collision. Set to false to allow it to be 'pushed' (see new examples).
* Removed Body.deltaAbsX and deltaAbsY as they are no longer used internally.
* Body.screenX and screenY moved to getters, no longer calculated every frame.
* ArcadePhysics now has setBounds and setBoundsToWorld, and you can specify which walls are created or not (left, right, up, down)
* Removed: Debug.renderSpriteTouching, Debug.renderLocalTransformInfo, Debug.renderWorldTransformInfo, Debug.renderSpriteCollision and Debug.dumpLinkedList.
* Body.setSize has been removed. Please use Body.setCircle, setRectangle or setPolygon instead.
* Added Device.silk for detecting a Kindle Fire and updated desktop OS check to exclude Kindles (thanks LuckieLordie)
* TilemapLayers now have debug and debugAlpha values, this turns on the drawing of the collision edges (very handy for debugging, as the name implies!)
* Tweens have a new event: onLoop.
* You can now load any binary file via the Loader: game.load.binary(key, url, callback) - the optional callback allows for post-load processing before entering the Cache.
* Group.set will let you deep set a new propery on a single child of the Group.
* Stage.display property added. A direct reference to the root Pixi Stage object (very useful for RenderTexture manipulation)
* Added Ejecta detection to Device (thanks endel)
* Tweens can now work with relative + and - values. You can do: `tween(sprite).to( { x: '+400' })` and it will add 400 to the current sprite.x value.
* Buttons now properly use their upFrame if set.
* InputHandler now has snapOffsetX and snapOffsetY properties so your snap grid doesn't have to be 0,0 aligned (thanks srmeier)
* Loader.progressFloat contains the actual non-rounded progress value, where-as Loader.progress contains a rounded value. Use progressFloat if you've > 100 files to load.
* Groups can now be added to other Groups as children via group.add() and group.addAt()
* Groups now have an 'alive' property, which can be useful when iterating through child groups with functions like forEachAlive.
* Added a new Project Template "Full Screen Mobile" which you can find in the resources folder. Contains html / css / layout needed for a deployed Phaser game.
* Body.speed - the current speed of the body.
* Body.angle - the current angle the Body is facing based on its velocity. This is not the same as the Sprite angle that may own the body.
* Body.linearDamping - This now replaces Body.drag and provides for a much smoother damping (friction) experience.
* Body.minBounceVelocity - If a Body has bounce set, this threshold controls if it should rebound or not. Use it to stop 'jittering' on bounds/tiles with super-low velocities.
* QuadTree.populate - you can pass it a Group and it'll automatically insert all of the children ready for inspection.
* Input.setMoveCallback allows you to set a callback that will be fired each time the activePointer receives a DOM move event.
* Math.distancePow(x1,y1,x2,y2,power) returns the distance between two coordinates at the given power.
* Physics.collide now supports the 2nd parameter as an array, for when you want to collide an object against a number of sprites that aren't all in the same Group.
* Physics.overlap now supports the 2nd parameter as an array, for when you want to overlap test an object against a number of sprites that aren't all in the same Group.
* Math.reverseAngle - reverses an angle (in radians).
* Math.normalizeAngle - normalises an angle, now in radians only.
* Math.normalizeLatitude - Normalizes a latitude to the [-90,90] range.
* Math.normalizeLongitude - Normalizes a longitude to the [-180,180] range.
* Phaser.Line added to the geometry classes, with full point on line/segment and intersection tests (see new examples)
* Phaser.CANVAS_PX_ROUND is a boolean. If 'true' the Canvas renderer will Math.floor() all coordinates before drawImage, stopping pixel interpolation. Defaults to false.
* Phaser.CANVAS_CLEAR_RECT is a boolean. If 'true' (the default) it will context.clearRect() every frame. If false this is skipped (useful if you know you don't need it)
* Collision now works between Sprites positioned via sprite.x/y, sprite.body.x/y or sprite.body.velocity.
* If you are tweening a sprite and still want physics collision, set `sprite.body.moves = false` otherwise it will fight against the tween motion.
* Game.enableStep will enable core game loop stepping. When enabled you must call game.step() directly (perhaps via a DOM button?), very useful for debugging!
* Debug.renderPhysicsBody(body, color) is extremely useful for debugging the new physics bodies. Will draw the outline + points in the color given.
* Debug.renderBodyInfo(sprite, x, y, color) will display lots of Sprite body data.
* Sprite.events.onBeginContact will be fired when a Body makes contact with another Body. Once contact is over an onEndContact event will be dispatched.
* Updated to latest Pixi.js dev branch build (pre 1.4 release)
* When a Sprite is destroyed any active filters are removed at the same time.
* Updated Pixi.js so that removing filters now works correctly without breaking the display list.
* Phaser.Canvas.create updated so it can be given an ID as the 3rd parameter (can also be set via new Game configuration object).
* Updated display/fullscreen example to reflect new full screen change.
* Loads of updates to the TypeScript definitions files - games fully compile now and lots of missing classes added :) (thanks Niondir)
* Removed 'null parent' check from Group constructor. Will parent to game.world only if parent value is undefined.
* The tutorials have now been translated into Spanish - thanks feiss :)
* separateY updated to re-implement the 'riding platforms' special condition (thanks cocoademon)
* SoundManager.onSoundDecode now dispatches the key followed by the sound object, also now dispatched by the Cache when doing an auto-decode on load.
* Switch method of using trimmed sprites to support scaling and rotation (thanks cocoademon)
* Most of the GameObjectFactory functions now have a group parameter, so you can do: game.add.sprite(x, y, frame, frameName, group) rather than defaulting to the World group.
* Group.countLiving and countDead used to return -1 if the Group was empty, but now return 0.
* Text can now be fixedToCamera, updated world/fixed to camera example to show this.
* ArcadePhysics.overlap and collide now recognise TileSprites in the collision checks.
* Lots of documentation fixes in the Tween class.
* Tweens fire an onLoop event if they are set to repeat. onComplete is now only fired for the final repeat (or never if the repeat is infinite)
* Pointer used to un-pause a paused game every time it was clicked/touched (this avoided some rogue browser plugins). Now only happens if Stage.disableVisibilityChange is true.
* Input doesn't set the cursor to default if it's already set to none.
* You can now collide a group against itself. This will check all children against each other, but not themselves (thanks cocoademon)
* RenderTexture.render / renderXY has a new parameter: renderHidden, a boolean which will allow you to render Sprites even if their visible is set to false.
* Added in prototype.constructor definitions to every class (thanks darkoverlordofdata)
* Group.destroy has a new parameter: destroyChildren (boolean) which will optionally call the destroy method of all Group children.
* Button.clearFrames method has been added.
* Device.quirksMode is a boolean that informs you if the page is in strict (false) or quirks (true) mode.
* Canvas.getOffset now runs a strict/quirks check and uses document.documentElement when calculating scrollTop and scrollLeft to avoid Chrome console warnings.
* The Time class now has its own Phaser.Timer which you can access through game.time.events. See the new Timer examples to show how to use them.
* Added StateManager.getCurrentState to return the currently running State object (thanks Niondir)
* Removed the console.log redirect from Utils as it was messing with Firefox.
* Body.acceleration is now much smoother and less eratic at high speeds.
* Removed ArcadePhysics binding to the QuadTree, so it can now be used independantly of the physics system.
* Removed ArcadePhysics.preUpdate and postUpdate as neither are needed any more.
* Body.bottom and Body.right are no longer rounded, so will give accurate sub-pixel values.
* Fixed lots of documentation in the Emitter class.
* The delta timer value used for physics calculations has had its cap limit modified from 1.0 to 0.05 in line with the core updates.
* Phaser.Math.min enhanced so you can now pass in either an array of numbers or lots of numbers as parameters to get the lowest.
* Phaser.Math.max added as the opposite of Math.min.
* Phaser.Math.minProperty and maxProperty added. Like Math.min/max but can be given a property an an array or list of objects to inspect.
* Added 'full' paramter to Body.reset, allowing you to control if motion or all data is reset or not.
* Exposed Group.pivot and Sprite.pivot to allow you to directly set the pivot points for rotation.
* Swapped to using the native and faster Array.isArray check.
* Added callback context parameter to Tween.onUpdateCallback(callback, context) to avoid having to bind or create anonymous functions.
* Updated TweenManager.removeAll so it flags all tweens as pendingDelete rather than nuking the array, to avoid tween callback array size errors (thanks DarkDev)
* Cache.getImageKeys returned __missing in the array, now excluded.
* Fixed Group.scale so you can now scale a Group directly.
* Removed World.scale as it was preventing Group.scale from working - you can still scale the world, but you'll need to factor in Input changes yourself.
* Moved 'dirty' flag for Tilemap to a per-layer flag. Fixes #242
* Group.length now returns the number of children in the Group regardless of their exists/alive state, or 0 if the Group has no children.
* Switch Camera.setBoundsToWorld to match world.bounds instead of world (thanks cocoademon)
* Fixed an issue where passing null as the Group parent wouldn't set it to game.world as it should have (thanks tito100)
* Phaser.Filter. A new way to use the new WebGL shaders/filters that the new version of Pixi supports.
* Phaser.BitmapData object. A Canvas you can freely draw to with lots of functions. Can be used as a texture for Sprites. See the new examples and docs for details.
* The entire Phaser library has been updated to match the new JSHint configuration.
* Added a .jshintrc so contributions can be run through JSHint to help retain formatting across the library (thanks kevinthompson)
* Added a new in-built texture. Sprites now use __default if no texture was provided (a 32x32 transparent PNG) or __missing if one was given but not found (a 32x32 black box with a green cross through it)
* Loader can now load JavaScript files. Just use game.load.script('key', 'url') - the file will be turned into a script tag in the document head on successful load.
* RenderTexture.render now takes a Phaser.Group. Also added renderXY for when you don't want to make a new Point object.
* Physics.overlap now supports Sprites, Groups or Emitters and can perform group vs. group (etc) overlap checks with a custom callback and process handler.
* Added Sound.externalNode which allows you to connect a Sound to an external node input rather than the SoundManager gain node.
* Added SoundManager.connectToMaster boolean. Used in conjunction with Sound.externalNode you can easily configure audio nodes to connect together for special effects.
* scrollFactorX/scrollFactorY have been added to TilemapLayers (thanks jcd-as)
* Phaser.Game parent can now be an HTMLElement or a string (thanks beeglebug)
* Now using the latest version of Pixi.js. Which means you can use all the sexy new WebGL filters :)
* Sprite.animations.getAnimation will return an animation instance which was added by name.
* Added Mouse.button which is set to the button that was pressed: Phaser.Mouse.LEFT_BUTTON, MIDDLE_BUTTON or RIGHT_BUTTON (thanks wKLV)
* Added Mouse.pointerLock signal which you can listen to whenever the browser enters or leaves pointer lock mode.
* StageScaleMode.forceOrientation allows you to lock your game to one orientation and display a Sprite (i.e. a "please rotate" screen) when incorrect.
* World.visible boolean added, toggles rendering of the world on/off entirely.
* Polygon class & drawPolygon method added to Graphics (thanks rjimenezda)
* Added Group.iterate, a powerful way to count or return children that match a certain criteria. Refactored Group to use iterate, lots of repeated code cut.
* Added Group.sort. You can now sort the Group based on any given numeric property (x, y, health), finally you can do depth-sorting :) Example created to show.
* Enhanced renderTexture so it can accept a Phaser.Group object and improved documentation and examples.
* Device.littleEndian boolean added. Only safe to use if the browser supports TypedArrays (which IE9 doesn't, but nearly all others do)
* You can now call game.sound.play() and simply pass it a key. The sound will play if the audio system is unlocked and optionally destroy itself on complete.
* Mouse.capture is a boolean. If set to true then DOM mouse events will have event.preventDefault() applied, if false they will propogate fully.
* The object returned by Math.sinCosGenerator now contains a length property.
* Lots of documentation fixes and updates across nearly all files. Tilemap now documented for example and lots of instances of 'Description' filled out.
* ArcadePhysics.updateMotion applies the dt to the velocity calculations as well as position now (thanks jcs)
* RequestAnimationFrame now retains the callbackID which is passed to cancelRequestAnimationFrame.
* Button now goes back to over state when setFrames used in action (thanks beeglebug)
* plugins now have a postUpdate callback (thanks cocoademon)
* Tided up the Graphics object (thanks BorisKozo)
* If running in Canvas mode and you have a render function it will save the context and reset the transform before running your render function.
* Sprite will now check the exists property of the Group it is in, if the Group.exists = false the Sprite won't update.
* If you specify 'null' as a Group parent it will now revert to using the World as the parent (before only 'undefined' worked)
* Skip preupdate/update for PIXI hierarchies in which an ancestor doesn't exist (thanks cocoademon)
* Loader.audio can now accept either an array of URL strings or a single URL string (thanks crazysam + kevinthompson)
* MSPointer updated to support IE11 by dropping the prefix from the event listeners.
* Device.cocoonJS added to detect if the game is running under Cocoon or a native browser.
* Loader now uses a new queue system internally, meaning you can have assets with the same key spread across different types.
* New: You'll now find a complete Basic project Template in the resources/Project Templates folder. Will add more complex ones soon.
* New: Phaser.Button now has the ability to set over/out/up/down sound effects so they play automatically based on those events.
* New: Added init method to plugins, to be called as they are added to the PluginManager (thanks beeglebug)
* New: Physics.Body now has a center property (issue 142, thanks MikeMnD)
* New: Lots of fixes across Full Screen Mode support. Input now works, scaling restores properly, world scale is correct and anti-alias support added.
* New: Added Group.cursor. This points to the first item added to a Group. You can move the cursor with Group.next() and Group.previous().
* New: Added Tween.isTweening(object) to check if an object is currently being tweened or not (thanks mikehamil10)
* New: Added getMagnitude, setMagnitude, normalize and isZero methods to Point (thanks beeglebug)
* New/Change: Group.callAll now supports nested functions and a context, making it really powerful!
* Updated: Fixed a few final bugs in the Sprite body and bounds calculations, in turn this resolved the Tilemap collision issues in the 1.1 release.
* Updated: Finished documentation for the Phaser.Button class.
* Updated: Fixed the Invaders game sample and enhanced it.
* Updated: Fixed the Star Struck game sample and enhanced it.
* Updated: If you pause an Animation, when you next play it it'll resume (un-pause itself).
* Updated: hexToRGB now accepts short hex codes (#EEE) (thanks beeglebug)
* Updated: State functions (preload, update, render, etc) are now passed the current game as a parameter (thanks beeglebug)
* Updated: If your game is running in Canvas (not WebGL) you can now set Stage.backgroundColor to rgba style CSS strings, allowing for semi-transparent game backgrounds.
* Updated: event.preventDefault() has been added to all Mouse event handlers.
* Updated: Sprite.deltaX/Y removed due to non-use. prevX/Y values moved to Sprite._cache.prevX/Y.
* Updated: Due to missing extends parameter the Sprite prototype was picking up functions from classes it never meant to (Button, TilemapLayer), now fully isolated.
* Fixed issue 135 - Added typeof checks into most ArcadePhysics functions to avoid errors with zero values.
* Fixed issue 136 - distanceTo using worldX/Y instead of x/y.
* Fixed lots of examples where the cursor keys / space bar were not locked from moving the browser page (if you find any more, please tell us!)
* Fixed issue 149 - Starling XML files now load properly again, also created an Example to show use of them (thanks haden)
* Fixed an issue where if the Starling XML file didn't contain a frameX/Y value it would crash on import.
* Fixed the Multiple Animations Example - it's now a lovely underwater scene :)
* Fixed issue 141 - If a Sprite is dragged and you release the Pointer while not over the Sprite, it will think it's still over it (thanks Paratron)
* Fixed issue 88 - Incorrect game.input.x/y values on click with scaled stage (thanks DrHackenstein)
* Fixed issue 143 - Entering full screen mode made the Input x/y coordinates go wrong.
* JSDoc is go! We've added jsdoc3 blocks to every property and function, in every file and published the API docs to the docs folder.
* Brand new Example system (no more php!) and over 150 examples to learn from too.
* New TypeScript definitions file generated (in the build folder - thanks to TomTom1229 for manually enhancing this).
* New Grunt based build system added (thanks to Florent Cailhol)
* New: Phaser.Animation.generateFrameNames - really useful when creating animation data from texture atlases using file names, not indexes.
* Added Sprite.play as a handy short-cut to play an animation already loaded onto a Sprite.
* Added Canvas.setUserSelect() to disable touchCallouts and user selections within the canvas.
* Added Keyboard.addKey() which creates a new Phaser.Key object that can be polled for updates, pressed states, etc. See the 2 new examples showing use.
* Added Button.freezeFrames boolean. Stops the frames being set on mouse events if true.
* Extended the Loader 404 error to display the url of the file that didn't load as well as the key.
* New: Direction constants have been added to Sprites and adjust based on body motion.
* Brand new Sprite.update loop handler. Combined with the transform cache fix and further optimisations this is now much quicker to execute.
* Added Keyboard.createCursorKeys() which creates an object with 4 Key objects inside it mapped to up, down, left and right. See the new example in the input folder.
* Added Body.skipQuadTree boolean for more fine-grained control over when a body is added to the World QuadTree.
* Re-implemented Angular Velocity and Angular Acceleration on the Sprite.body and created 2 new examples to show use.
* Added Sprite.fixedToCamera boolean. A Sprite that is fixed to the camera doesn't move with the world, but has its x/y coordinates relative to the top-left of the camera.
* Added Group.createMultiple - useful when you need to create a Group of identical sprites for pooling, such as bullets.
* Added Group.total. Same as Group.length, but more in line with the rest of the Group naming.
* Added Sprite.outOfBoundsKill boolean flag. Will automatically kill a sprite that leaves the game World bounds (off by default).
* Lots of changes and fixes in ArcadePhysics, including:
* Functions with "mouse" in the title have been updated to "pointer" to more accurately reflect what they do.
* New velocity functions: moveToObject, moveToPointer, moveToXY
* New acceleration functions: accelerateToObject, accelerateToPointer, accelerateToXY
* New distance functions: distanceBetween, distanceToXY, distanceToPointer
* New angle functions: angleBetween, angleToXY, angleToPointer
* velocityFromAngle and velocityFromRotation added with examples created.
* Added killOnComplete parameter to Animation.play. Really useful in situations where you want a Sprite to animate once then kill itself on complete, like an explosion effect.
* Added Sprite.loadTexture(key, frame) which allows you to load a new texture set into an existing sprite rather than having to create a new sprite.
* Added Sprite.destroy back in again and made it a lot more robust at cleaning up child objects.
* Added 'return this' to all the core Loader functions so you can chain load calls if you so wish.
* Added Text.destroy() and BitmapText.destroy(), also updated Group.remove to make it more bullet-proof when an element doesn't have any events.
* Added Phaser.Utils.shuffle to shuffle an array.
* Added Graphics.destroy, x, y and updated angle functions.
* Added AnimationManager.refreshFrame - will reset the texture being used for a Sprite (useful after a crop rect clear)
* Added Physics.overlap(sprite1, sprite2) for quick body vs. body overlap tests with no separation performed.
* On a busy page it's possible for the game to boot with an incorrect stage offset x/y which can cause input events to be calculated wrong. A new property has been added to Stage to combat this issue: Stage.checkOffsetInterval. By default it will check the canvas offset every 2500ms and adjust it accordingly. You can set the value to 'false' to disable the check entirely, or set a higher or lower value. We recommend that you get the value quite low during your games preloader, but once the game has fully loaded hopefully the containing page will have settled down, so it's probably safe to disable the check entirely.
* Added Rectangle.floorAll to floor all values in a Rectangle (x, y, width and height).
* Renamed Phaser.Text.text to Phaser.Text.content to avoid conflict and overwrite from Pixi local var.
* Renamed Phaser.Text.style to Phaser.Text.font to avoid conflict and overwrite from Pixi local var.
* Phaser.Button now sets useHandCursor to true by default.
* Change: When you start a new State all active tweens are now purged.
* When the game boots it will now by default disable user-select and touch action events on the game canvas.
* Moved LinkedList.dump to Debug.dumpLinkedList(list)
* Phaser.Animation.Frame is now Phaser.Frame
* Phaser.Animation.FrameData is now Phaser.FrameData
* Phaser.Animation.Parser is now Phaser.AnimationParser (also the file has renamed from Parser.js to AnimationParser.js)
* Phaser.Loader.Parser is now Phaser.LoaderParser (also the file has renamed from Parser.js to LoaderParser.js)
* Change: We've removed the scrollFactor property from all Game Objects. Sorry, but the new Camera system doesn't work with it and it caused all kinds of issues anyway. We will sort out a replacement for it at a later date.
* Change: World now extends Phaser.Group. As a result we've updated GameObjectFactory and other classes that linked to it. If you have anywhere in your code that used to reference world.group you can just remove 'group' from that. So before, world.group.add() is now just world.add().
* Change: The Camera has been completely revamped. Rather than adjusting the position of all display objects (bad) it now just shifts the position of the single world container (good!), this is much quicker and also stops the game objects positions from self-adjusting all the time, allowing for them to be properly nested with other containers.
* Made Sprite.body optional and added in checks, so you can safely null the Sprite body object if using your own physics system and not impact rendering.
* Moved the Camera update checks to World.postUpdate, so all the sprites get the correct adjusted camera position.
* The default Game.antialias value is now 'true', so graphics will be smoothed automatically in canvas. Disable it via the Game constructor or Canvas utils.
* Phaser.Group now automatically calls updateTransform on any child added to it (avoids temp. frame glitches when new objects are rendered on their first frame).
* Complete overhaul of Physics.Arcade.Body - now significantly more stable and faster too.
* Updated ArcadePhysics.separateX/Y to use new body system - much better results now.
* Added World.postUpdate - all sprite position changes, as a result of physics, happen here before the render.
* Added Animation.paused - can be set to true/false.
* Added support for Body.maxVelocity (thanks cocoademon)
* InputHandler now creates the _pointerData array on creation and populates with one empty set of values, so pointerOver etc all work before a start call.
* Removed the callbackContext parameter from Group.callAll because it's no longer needed.
* Updated Group.forEach, forEachAlive and forEachDead so you can now pass as many parameters as you want, which will all be given to the callback after the child.
* Updated build script so it can be run from the command-line and includes UMD wrappers (thanks iaincarsberg)
* World.randomX/Y now returns values anywhere in the world.bounds range (if set, otherwise 0), including negative values.
* Updated InputHandler to use Math.round rather than Math.floor when snapping an object during drag.
* If you didn't provide the useNumericIndex parameter then AnimationManager.add will set the value by looking at the datatype of the first element in the frames array.
* Group.create now sets the visible and alive properties of the Sprite to the same value as the 'exists' parameter.
* World.randomX/Y now works with negative World.bounds values.
* Tweens .to will now always return the parent (thanks powerfear)
* You can now pass a PIXI.Texture to Sprite (you also need to pass a Phaser.Frame as the frame parameter) but this is useful for Sprites sharing joint canvases.
* Group.alpha is now exposed publically and changes the Group container object (not the children directly, who can still have their own alpha values)
* Device.webGL uses new inspection code to accurately catch more webGL capable devices.
* Debug.renderSpriteBody updated to use a the new Sprite.Body.screenX/Y properties.
* Additional checks added to AnimationManager.frame/frameName on the given values.
* You can now null a Sprite.crop and it will clear down the crop rect area correctly.
* Phaser.Time physicsElapsed delta timer clamp added. Stops rogue iOS / slow mobile timer errors causing crazy high deltas.
* Animation.generateFrameNames can now work in reverse, so the start/stop values can create frames that increment or decrement respectively.
* Loader updated to use xhr.responseText when loading json, csv or text files. xhr.response is still used for Web Audio binary files (thanks bubba)
* Input.onDown and onUp events now dispatch the original event that triggered them (i.e. a MouseEvent or TouchEvent) as the 2nd parameter, after the Pointer (thanks rezoner)
* Updated Sprite.crop significantly. Values are now cached, stopping constant Texture frame updates and you can do sprite.crop.width++ for example (thanks haden)
* Change: Sprite.crop needs to be enabled with sprite.cropEnabled = true.
* Sprite.loadTexture now works correctly with static images, RenderTextures and Animations.
* Lots of fixes within Sprite.bounds. The bounds is now correct regardless of rotation, anchor or scale of the Sprite or any of its parent objects.
* QuadTree bug found in 1.0.5 now fixed. The QuadTree is updated properly now using localTransform values.
* Fixed the Bounce.In and Bounce.InOut tweens (thanks XekeDeath)
* Fixed an issue in Animation.update where if the game was paused it would get an insane delta timer throwing a uuid error.
* Added PixiPatch.js to patch in a few essential features until Pixi is updated.
* Fixed issue in Animation.play where the given frameRate and loop values wouldn't overwrite those set on construction.
* Fixed small bug stopping Tween.pause / resume from resuming correctly when called directly.
* Fixed an issue where Tweens.removeAll wasn't clearing tweens in the addition queue.
* Fixed Particle Emitters when using Emitter width/height (thanks XekeDeath)
* Made animation looping more robust when skipping frames (thanks XekeDeath)
* Fix for incorrect new particle positioning (issue #73) (thanks cottonflop)
* Fixed issue in Sound.play where if you gave a missing marker it would play the whole sound sprite instead.
* Button.setFrames will set the current frame based on the button state immediately.
* Loaded.setPreloadSprite now rounds the width/height values and starts from 1. This fixes canvas draw errors in IE9/10 and Firefox.
* Fixed issue causing Keyboard.justPressed to always fire (thanks stemkoski)
* Fixed bug in LinkedList#remove that could cause first to point to a dead node (thanks onedayitwillmake)
* Fixed Cache.addDefaultImage so the default image works in Canvas as well as WebGL. Updated to a new image (32x32 black square with green outline)
* Fixed a bug in the Sprite transform cache check that caused the skew/scale cache to get constantly invalidated - now only updates as needed, significant performance increase!
* Fixed typo in StageScaleMode so it's not pageAlignVeritcally any longer, but pageAlignVertically.
* Fixed issue in Group.countLiving / countDead where the value was off by one (thanks mjablonski)
* Fixed issue with a jittery Camera if you moved a Sprite via velocity instead of x/y placement.
* Fixed the RandomDataGenerator.sow method so if you give in the same seed you'll now get the same results (thanks Hsaka)
* Fixed Issue #101 (Mouse Button 0 is not recognised, thanks rezoner)
* Fixed an issue where creating an animation with just one frame with an index of zero would cause a UUID error (thanks SYNYST3R1)
* Fixed Rectangle.union (thanks andron77)
* Fixed Sound.resume so it now correctly resumes playback from the point it was paused (fixes issue 51, thanks Yora).
* Fixed issue 105 where a dragged object that was destroyed would cause an Input error (thanks onedayitwillmake)
* Fixed Issue 111 - calling Kill on a Phaser.Graphics instance causes error on undefined events.
* Game.destroy will now stop the raf from running as well as close down all input related event listeners (issue 92, thanks astrism)
* Pixel Perfect click detection now works even if the Sprite is part of a texture atlas.
* Added check into Pointer.move to always consider a Sprite that has pixelPerfect enabled, regardless of render ID.

* Fixed issue in FrameData.getFrameIndexes where the input array was being ignored.
* Added Math.numberArray - Returns an Array containing the numbers from min to max (inclusive), useful for animation frame construction.
* Fixed a horrendously sneaky bug: If a new tween was created in the onComplete callback of a tween about to be deleted, it would get automatically spliced.
* Added a pendingDelete property to Tween to stop tweens that were removed during a callback from causing update errors during the TweenManager loop.
* Added Group.length property.
* Added explicit x/y attributes to Phaser.Text to make it work with the camera system (thanks cocoademon).

* Removed Group.sort dummy entry until it's working.
* Removed ArcadePhysics.postUpdate.
* Updated Sprite.update to set renderable to false when the object goes out of Camera, not 'visible' false, otherwise it stops the transform being updated by Pixi.

* Small fix to Phaser.Canvas to stop it from setting overflow hidden if the parent DOM element doesn't exist.
* Added Loader.setPreloadSprite(sprite, direction) - this will automatically apply a crop rect to the Sprite which is updated in line with the load progress.
* A lot of changes inside the StateManager. State functions are now passed through link() which automatically creates the key Game properties (load, input, etc)
* Fixed a bug in getFrameByName that wouldn't return the first frame in the array.
* Updated Phaser.Rectangle.intersects to use x and y instead of left and top so it can be used to check Physics bodies overlapping.
* Fixed issue in Cache where the Frame index wasn't being set correctly (thanks Cameron)
* Fixed issue in Sprite where boundsY wasn't set (thanks Cameron)
* For some reason there were 2 copies of the Canvas class in the build file - fixed, a few KB saved :)

* Heavily optimised Group so it no longer creates any temporary variables in any methods.
* Added Game.renderer which can be HEADLESS, CANVAS or WEBGL (coming soon)
* Added Sprite.render which is a reference to IRenderer.renderSprite, but can be overridden for custom handling.
* Refactored QuadTree so it no longer creates any temporary variables in any methods.
* The Sprite Renderer now uses a single setTransform for scale, rotation and translation that respects the Sprite.origin value in all cases.

* Added 2 new State functions: loadRender and loadUpdate, are called the same as render and update but only during the load process
* Fixed Input.stopDrag so it fires an onInputUp event as well from the sprite.
* Added support for a preRender state - very useful for certain types of special effects.
* Cameras are now limited so they can never be larger than the Game.Stage size.
* Added a new Button Game Object for easily creating in-game UI and menu systems.
* Fixed bug where Sprite.alpha wasn't properly reflecting Sprite.texture.alpha.
* Fixed bug where the hand cursor would be reset on input up, even if the mouse was still over the sprite.
* Fixed bug where pressing down then moving out of the sprite area wouldn't properly reset the input state next time you moved over the sprite.

* Fixed the CircleUtils.contains and containsPoint methods.
* Fixed issue with Input.speed values being too high on new touch events.
* Added Sprite.bringToTop()
* Added Stage.disableVisibilityChange to stop the auto pause/resume from ever firing.

* Added references to all the event listener functions so they can be cleanly destroyed.
* Fixed interesting Firefox issue when an audio track ended it fired another 'canplaythrough' event, confusing the Loader.
* Added the new PluginManager. Moved all the Camera FX over to plugins. Everything will be a plugin from now on.
* Added Sprite.transform.centerOn(x,y) to quickly center a sprite on a coordinate without messing with the sprite origin and regardless of rotation.
* Added Input.pollRate - this lets you limit how often Pointer events are handled (0 = every frame, 1 = every other frame, etc)
* Renamed the 'init' function to 'preload'. It now calls load.start automatically.
* Added CanvasUtils class, including ability to set image rendering, add a canvas to the dom and other handy things.
* Virtually every class now has documentation - if you spot a typo or something missing please shout (thanks pixelpicosean).
* Grunt file updated to produce the new Special FX JS file (thanks HackManiac).

* Added Basic.ignoreGlobalUpdate - stops the object being updated as part of the main game loop, you'll need to call update on it yourself
* Added Basic.ignoreGlobalRender - stops the object being rendered as part of the main game loop, you'll need to call render on it yourself
* Added forceUpdate and forceRender parameters to Group.update and Group.render respectively. Combined with ignoreGlobal you can create custom rendering set-ups

* Added Camera black list support to Sprite and Group along with Camera.show, Camera.hide and Camera.isHidden methods to populate them.
* Added GameMath.rotatePoint to allow for point rotation at any angle around a given anchor and distance
* Updated World.setSize() to optionally update the VerletManager dimensions as well
* Updated Sprite.inCamera to correctly apply the scrollFactor to the camera bounds check
* Added Loader.crossOrigin property which is applied to loaded Images
* Added AnimationManager.destroy() to clear out all local references and objects
* Added the clearAnimations parameter to Sprite.loadGraphic(). Allows you to change animation textures but retain the frame data.
* Added the GameObjectFactory to Game. You now make Sprites like this: game.add.sprite(). Much better separation of game object creation methods now. But you'll have to update ALL code, sorry! (blame JesseFreeman for breaking your code and coming up with the idea :)
* Added GameObjectFactory methods to add existing objects to the game world, such as existingSprite(), existingTween(), etc.
* Added the GameObjectFactory to Phaser.State
* Added new format parameter to Loader.addTextureAtlas defining the format. Currently supported: JSON Array and Starling/Sparrow XML.

* Updated the PauseScreen to show a subtle animation effect, making it easier to create your own interesting pause screens.
* Modified Game so it splits into 3 loops - bootLoop, pauseLoop and loop (the core loop).
* Updated the BootScreen with the new logo and new color cycle effect.
* Added Game.isRunning - set to true once the Game.boot process is over IF you gave some functions to the constructor or a state.
* Fixed small bug in Signal.removeAll where it could try to shorten the _bindings even if undefined.
* Added the new FXManager which is used for handling all special effects on Cameras (and soon other game objects).
* Removed Flash, Fade and Shake from the Camera class and moved to the new SpecialFX project.
* SpecialFX compiles to phaser-fx.js in the build folder, which is copied over to Tests. If you don't need the FX, don't include the .js file.
* The project is now generating TypeScript declaration files and all Tests were updated to use them in their references.
* Fixed a bug in Flash, Fade and Shake where the duration would fail on anything above 3 seconds.
* Fixed a bug in Camera Shake that made it go a bit haywire, now shakes correctly.
* Added new Scanlines Camera FX.
* Fixed offset values being ignored in GeomSprite.renderPoint (thanks bapuna).
* Added new Mirror Camera FX. Can mirror the camera image horizontally, vertically or both with an optional fill color overlay.
* Added Camera.disableClipping for when you don't care about things being drawn outside the edge (useful for some FX).
* Updated TilemapLayer so that collision data is now stored in _tempTileBlock to avoid constant array creation during game loop.
* TilemapLayer.getTileOverlaps() now returns all tiles the object overlapped with rather than just a boolean.
* Tilemap.collide now optionally takes callback and context parameters which are used if collision occurs.
* Added Tilemap.collisionCallback and Tilemap.collisionCallbackContext so you can set them once and not re-set them on every call to collide.
* Collision.separateTile now has 2 extra parameters: separateX and separateY. If true the object will be separated on overlap, otherwise just the overlap boolean result is returned.
* Added Tile.separateX and Tile.separateY (both true by default). Set to false if you don't want a tile to stop an object from moving, you just want it to return collision data to your callback.
* Added Tilemap.getTileByIndex(value) to access a specific type of tile, rather than by its map index.
* Added TilemapLayer.putTile(x,y,index) - allows you to insert new tile data into the map layer (create your own tile editor!).
* TilemapLayer.getTileBlock now returns a unique Array of map data, not just a reference to the temporary block array
* Added TilemapLayer.swapTile - scans the given region of the map for all instances of tileA and swaps them for tileB, and vice versa.
* Added TilemapLayer.replaceTile - scans the given region of the map and replaces all instances of tileA with tileB. tileB is left unaffected.
* Added TilemapLayer.fillTiles - fills the given region of the map with the tile specified.
* Added TilemapLayer.randomiseTiles - fills the given region of the map with a random tile from the list specified.
* Added fun new "map draw" test - rebound those carrots! :)
* Changed SoundManager class to respect volume on first play (thanks initials and hackmaniac)
* Large refactoring. Everything now lives inside the Phaser module, so all code and all tests have been updated to reflect this. Makes coding a tiny bit more verbose but stops the framework from globbing up the global namespace. Also should make code-insight work in WebStorm and similar editors.
* Added the new GeomSprite object. This is a sprite that uses a geometry class for display (Circle, Rectangle, Point, Line). It's extremely flexible!
* Added Geometry intersection results objects.
* Added new Collision class and moved some functions there. Contains all the Game Object and Geometry Intersection methods.
* Can now create a sprite animation based on frame names rather than indexes. Useful when you've an animation inside a texture atlas. Added test to show.
* Added addKeyCapture(), removeKeyCapture() and clearCaptures() to Input.Keyboard. Calls event.preventDefault() on any keycode set to capture, allowing you to avoid page scrolling when using the cursor keys in a game for example.
* Added new Motion class which contains lots of handy functions like 'moveTowardsObject', 'velocityFromAngle' and more.
* Tween Manager added. You can now create tweens via Game.createTween (or for more control game.tweens). All the usual suspects are here: Bounce, * Elastic, Quintic, etc and it's hooked into the core game clock, so if your game pauses and resumes your tweens adjust accordingly.
* Added ability to set Sprite frame by name (sprite.frameName), useful when you've loaded a Texture Atlas with filename values set rather than using frame indexes.
* Updated texture atlas 4 demo to show this.
* Fixed a bug that would cause a run-time error if you tried to create a sprite using an invalid texture key.
* Added in DynamicTexture support and a test case for it.
