Change Log
==========

Version 1.1.4 - "Kandor" - February 5th 2014
--------------------------------------------

Significant API changes:

* 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.


New features:

* Phaser.Timer is now feature complete and fully documented. You can create Phaser.TimerEvents on a Timer and lots of new examples have been provided.
* Gamepad API support has been added with lots of new examples (thanks Karl Macklin)
* Phaser.Game constructor can now be passed a single object containing all of your game settings + Stage settings. Useful for advanced configurations.
* The width/height given to Phaser.Game can now be percentages, i.e. "100%" will set the width to the maximum window innerWidth.
* Added a stage.fullScreenScaleMode property to determine scaling when fullscreen (thanks oysterCrusher)
* Added support for margin and spacing around a frame in Loader.spritesheet.
* Added Device.vibration to check if the Vibration API is available or not.
* Added Device.trident and Device.tridentVersion for testing IE11.
* 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!
* Game.disableStep turns core update loop stepping off.
* 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.

Updates:

* 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)


Bug Fixes:

* 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)
* Fixed Pixi bug (#425) incorrect width property for multi-line BitmapText (thanks jcd-as)
* Tween.onStart is now called when the tween starts AFTER the delay value, if given (thanks stevenbouma)
* Sprites that are fixedToCamera can now be input dragged regardless of world position (thanks RafaelOliveira)
* RenderTexture now displays correctly in Canvas games.
* Canvas.addToDOM is now more robust when applying the overflowHidden style.
* Fixed Pixi.StripShader which should stop the weird TileSprite GPU issues some were reporting (thanks GoodboyDigital)
* Patched desyrel.xml so it doesn't contain any zero width/height characters, as they broke Firefox 25.
* Cache.addSound now implements a locked attribute (thanks haden)
* Sound now checks for CocoonJS during playback to avoid readyState clash (thanks haden)
* Buttons now clear previously set frames correctly if you call setFrames.
* Sounds will now loop correctly if they are paused and resumed (thanks haden)
* InputHandler.checkBoundsRect and checkBoundsSprite now take into account if the Sprite is fixedToCamera or not.
* Removed the frame property from TileSprites as it cannot use them, it tiles the whole image only, not just a section of it.
* Fixed WebGLRenderer updateGraphics bug (thanks theadam)
* Removed duplicate Timer.create line (thanks hstolte)
* Fixed issue with the camera being slightly out of sync with 'fixedToCamera' sprites.
* 1px camera jitter issue fixed where map is same size, or smaller than the game size.


Version 1.1.3 - "Arafel" - November 29th 2013
---------------------------------------------

New features:

* 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.
* PluginManager.remove, added PluginManager.removeAll (thanks crazysam)
* 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.

Updates:

* 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.

Bug Fixes:

* Lots of fixes to the TypeScript definitions file (many thanks gltovar)
* Tilemap commands use specified layer when one given (thanks Izzimach)
* Mouse.stop now uses the true useCapture, which means the event listeners stop listening correctly (thanks beeglebug)
* Input Keyboard example fix (thanks Atrodilla)
* BitmapText.destroy now checks if it has a canvas before calling parentNode on it.
* Group.swap had a hellish to find bug that only manifested when B-A upward swaps occured. Hours of debugging later = bug crushed.
* Point.rotate asDegrees fixed (thanks BorisKozo)
* ArcadePhysics.separateTile wasn't returning the value, so the custom process callback wasn't getting called (thanks flameiguana)
* StageScaleMode.forceOrientation now correctly stores the forcePortrait value (thanks haden)
* Fixes to Math and Loader (thanks theJare)
* Tween - isRunning not reset when non-looped tween completes (thanks crazysam + kevinthompson)
* Math.normalizeAngle and Math.wrapAngle (thanks theJare)
* Device.isTouch modified to test maxTouchPointers instead of MSPointer.
* InputHandler.checkPointerOver now checks the visible status of the Sprite Group before processing.
* The Sprite hulls (used for tile collision) were not being updated in sprite->sprite separations (thanks jcs)
* Plugins that had a postUpdate but no Update weren't being marked as active (thanks crazysam)
* StateManager.onPausedCallback function is not called when the game is paused (thanks haden)
* Fix for 'jitter' in scrolling where tilemaps & sprites are one frame off (thanks jcs)


Version 1.1.2 - November 1st 2013
---------------------------------

* 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.


Version 1.1.1 - October 26th 2013
---------------------------------

* Quick patch to get Phaser.AUTO working again on Firefox / Android.
* Any key added via addKey now automatically adds it to the capture list.


Version 1.1 - October 25th 2013
-------------------------------

What's New:

* 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).

What's changed:

* 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).

What has been updated:

* 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 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 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)

Version 1.0.5 - September 20th 2013
-----------------------------------

* 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).
* Fixed issue stopping multiple animations from playing, only the most recent would play (frames array was being overwritten, thanks Legrandk)
* Updated Debug.renderSpriteBounds() so it doesn't use the deprecated Sprite.worldView any more (thanks MikeMnD)
* Added 2 new properties to the Text object: Text.text and Text.style, both are getter/setters and don't flag dirty unless changed, so safe for core loop use.
* Removed the exists check from Group.callAll, it now runs on all children (as the name implies)
* Added Group.callAllExists - you can now call a function on all children who have exists = the provided boolean.
* Finished off the Breakout example game - now fully playable, proper rebound, scoring, lives, etc.
* 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.
* BUG: There is a known issue where the wrong rect coordinates are given to the QuadTree if the Sprite is a child of a Group or another Sprite which has an x/y offset.


Version 1.0.4 - September 18th 2013
-----------------------------------

* 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 :)

-----------------------------------

* FrameData.getFrameIndexes and getFrameIndexesByName refactored into a more versatile getFrames function.
* Various fixes to looping parameters in the Sound system.
* Documentation started across most classes. Keep track of progress in the Docs folder.
* Optimised AnimationManager.add so it will only get the required frames rather than all of them and is now faster at parsing the frame data.
* Fixed Phaser.Text and Phaser.BitmapText so they now render correctly and added several Text examples.


Version 1.0.2 - September 16th 2013
-----------------------------------

* Added optional parameter to Animation.stop: resetFrame. If true the animation will be stopped and then the current frame reset to the first frame in the animation.
* Fixed an issue causing 'explode' particle bursts to ignore the quantity parameter.
* Added 'collideWorldBounds' to Emitter.makeParticles function.
* Added Emitter.angularDrag

* Added in lots of Particle examples
* Added in the start of a Breakout game
* Added in the start of a Platformer game

* 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.

* 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.

* Added support for pagehide and pageshow events to Stage, hooked in to the pause/resume game methods.
* Extended Device audio checks to include opus and webm.
* Updated Loader and Cache so they now support loading of Audio() tags as well as Web Audio.
* Set Input.recordPointerHistory to false, you now need to enable the pointer tracking if you wish to use it.

* 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
* Fixed Loader.progress calculation so it now accurately passes a value between 0 and 100 to your loader callback
* Added a 'hard reset' parameter to Input.reset. A hard reset clears Input signals (such as on a state swap), a soft (such as on game pause) doesn't
* Added Device.isConsoleOpen() to check if the browser console is open. Tested on Firefox with Firebug and Chrome with DevTools
* Added delay parameter to Tween.to()

* Added the GameObjectFactory to Phaser.State
* Added new format parameter to Loader.addTextureAtlas defining the format. Currently supported: JSON Array and Starling/Sparrow XML.


Version 0.9.5
-------------

* Moved the BootScreen and PauseScreen out of Stage into their own classes (system/screens/BootScreen and PauseScreen).
* 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)


Version 0.9.4
--------------

* Added Tilemap.getTile, getTileFromWorldXY, getTileFromInputXY
* Added Tilemap.setCollisionByIndex and setCollisionByRange
* Added GameObject.renderRotation boolean to control if the sprite will visually rotate or not (useful when angle needs to change but graphics don't)
* Added additional check to Camera.width/height so you cannot set them larger than the Stage size
* Added Collision.separateTile and Tilemap.collide
* Fixed Tilemap bounds check if map was smaller than game dimensions
* Fixed: Made World._cameras public, World.cameras and turned Game.camera into a getter for it (thanks Hackmaniac)
* Fixed: Circle.isEmpty properly checks diameter (thanks bapuna)
* Updated Gruntfile to export new version of phaser.js wrapped in a UMD block for require.js/commonJS (thanks Hackmaniac)


Version 0.9.3
-------------

* Added the new ScrollZone game object. Endlessly useful but especially for scrolling backdrops. Created 6 example tests.
* Added GameObject.hideFromCamera(cameraID) to stop an object rendering to specific cameras (also showToCamera and clearCameraList)
* Added GameObject.setBounds() to confine a game object to a specific area within the world (useful for stopping them going off the edges)
* Added GameObject.outOfBoundsAction, can be either OUT OF BOUNDS STOP which stops the object moving, or OUT OF BOUNDS KILL which kills it.
* Added GameObject.rotationOffset. Useful if your graphics need to rotate but weren't drawn facing zero degrees (to the right).
* Added shiftSinTable and shiftCosTable to the GameMath class to allow for quick iteration through the data tables.
* Added more robust frame checking into AnimationManager
* Re-built Tilemap handling from scratch to allow for proper layered maps (as exported from Tiled / Mappy)
* Tilemap no longer requires a buffer per Camera (in prep for WebGL support)
* Fixed issues with Group not adding reference to Game to newly created objects (thanks JesseFreeman)
* Fixed a potential race condition issue in Game.boot (thanks Hackmaniac)
* Fixed issue with showing frame zero of a texture atlas before the animation started playing (thanks JesseFreeman)
* Fixed a bug where Camera.visible = false would still render
* Removed the need for DynamicTextures to require a key property and updated test cases.
* You can now pass an array or a single value to Input.Keyboard.addKeyCapture().


Version 0.9.2
-------------

* Fixed issue with create not being called if there was an empty init method.
* Added ability to flip a sprite (Sprite.flipped = true) + a test case for it.
* Added ability to restart a sprite animation.
* Sprite animations don't restart if you call play on them when they are already running.
* Added Stage.disablePauseScreen. Set to true to stop your game pausing when the tab loses focus.


Version 0.9.1
-------------

* Added the new align property to GameObjects that controls placement when rendering.
* Added an align example to the Sprites test group (click the mouse to change alignment position)
* Added a new MicroPoint class. Same as Point but much smaller / less functions, updated GameObject to use it.
* Completely rebuilt the Rectangle class to use MicroPoints and store the values of the 9 points around the edges, to be used
for new collision system.
* Game.Input now has 2 signals you can subscribe to for down/up events, see the Sprite align example for use.
* Updated the States examples to bring in-line with 0.9 release.

Version 0.9
-----------

* 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.


Version 0.8
-----------

* 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.


Version 0.7
-----------

* Renamed FullScreen to StageScaleMode as it's much more fitting. Tested across Android and iOS with the various scale modes.
* Added in world x/y coordinates to the input class, and the ability to get world x/y input coordinates from any Camera.
* Added the RandomDataGenerator for seeded random number generation.
* Setting the game world size now resizes the default camera (optional bool flag)


Version 0.6
-----------

* Added in Touch support for mobile devices (and desktops that enable it) and populated x/y coords in Input with common values from touch and mouse.
* Added new Circle geometry class (used by Touch) and moved them into a Geom folder.
* Added in Device class for device inspection.
* Added FullScreen class to enable full-screen support on mobile devices (scrolls URL bar out of the way on iOS and Android)


Version 0.5
-----------

* Initial release
