* @overview
*
* Phaser - http://phaser.io
*
* v2.4.9 "Four Kings" - Built: Fri Jun 10 2016 16:18:53
*
* By Richard Davey http://www.photonstorm.com @photonstorm
*
* Phaser is a fun, free and fast 2D game framework for making HTML5 games
* for desktop and mobile web browsers, supporting Canvas and WebGL rendering.
*
* Phaser uses Pixi.js for rendering, created by Mat Groves http://matgroves.com @Doormat23
* Phaser uses p2.js for full-body physics, created by Stefan Hedman https://github.com/schteppe/p2.js @schteppe
* Phaser contains a port of N+ Physics, converted by Richard Davey, original by http://www.metanetsoftware.com
*
* Many thanks to Adam Saltsman (@ADAMATOMIC) for releasing Flixel, from which both Phaser
* and my love of framework development originate.
*
* Follow development at http://phaser.io and on our forum
*
* "If you want your children to be intelligent, read them fairy tales."
* "If you want them to be more intelligent, read them more fairy tales."

/**
* Signals are what Phaser uses to handle events and event dispatching.
* You can listen for a Signal by binding a callback / function to it.
* This is done by using either `Signal.add` or `Signal.addOnce`.
*
* For example you can listen for a touch or click event from the Input Manager
* by using its `onDown` Signal:
*
* `game.input.onDown.add(function() { ... });`
*
* Rather than inline your function, you can pass a reference:
*
* `game.input.onDown.add(clicked, this);`
* `function clicked () { ... }`
*
* In this case the second argument (`this`) is the context in which your function should be called.
*
* Now every time the InputManager dispatches the `onDown` signal (or event), your function
* will be called.
*
* Very often a Signal will send arguments to your function.
* This is specific to the Signal itself.
* If you're unsure then check the documentation, or failing that simply do:
*
* `Signal.add(function() { console.log(arguments); })`
*
* and it will log all of the arguments your function received from the Signal.
*
* Sprites have lots of default signals you can listen to in their Events class, such as:
*
* `sprite.events.onKilled`
*
* Which is called automatically whenever the Sprite is killed.
* There are lots of other events, see the Events component for a list.
*
* As well as listening to pre-defined Signals you can also create your own:
*
* `var mySignal = new Phaser.Signal();`
*
* This creates a new Signal. You can bind a callback to it:
*
* `mySignal.add(myCallback, this);`
*
* and then finally when ready you can dispatch the Signal:
*
* `mySignal.dispatch(your arguments);`
*
* And your callback will be invoked. See the dispatch method for more details.

/**
* DeviceButtons belong to both `Phaser.Pointer` and `Phaser.SinglePad` (Gamepad) instances.
*
* For Pointers they represent the various buttons that can exist on mice and pens, such as the left button, right button,
* middle button and advanced buttons like back and forward.
*
* Access them via `Pointer.leftbutton`, `Pointer.rightButton` and so on.
*
* On Gamepads they represent all buttons on the pad: from shoulder buttons to action buttons.
*
* At the time of writing this there are device limitations you should be aware of:
*
* - On Windows, if you install a mouse driver, and its utility software allows you to customize button actions
* (e.g., IntelliPoint and SetPoint), the middle (wheel) button, the 4th button, and the 5th button might not be set,
* even when they are pressed.
* - On Linux (GTK), the 4th button and the 5th button are not supported.
* - On Mac OS X 10.5 there is no platform API for implementing any advanced buttons.
*

* The Text Bounds is a rectangular region that you control the dimensions of into which the Text object itself is positioned,

* set through the setters `Text.boundsAlignH` and `Text.boundsAlignV`. Bounds alignment is independent of text alignment.
*
* For example: If your game is 800x600 in size and you set the text bounds to be 0,0,800,600 then by setting boundsAlignH to
* 'center' and boundsAlignV to 'bottom' the text will render in the center and at the bottom of your game window, regardless of
* how many lines of text there may be. Even if you adjust the text content or change the style it will remain at the bottom center
* of the text bounds.
*
* This is especially powerful when you need to align text against specific coordinates in your game, but the actual text dimensions
* may vary based on font (say for multi-lingual games).
*
* If `Text.wordWrapWidth` is greater than the width of the text bounds it is clamped to match the bounds width.
*
* Call this method with no arguments given to reset an existing textBounds.
*
* It works by calculating the final position based on the Text.canvas size, which is modified as the text is updated. Some fonts
* have additional padding around them which you can mitigate by tweaking the Text.padding property. It then adjusts the `pivot`
* property based on the given bounds and canvas size. This means if you need to set the pivot property directly in your game then
* you either cannot use `setTextBounds` or you must place the Text object inside another DisplayObject on which you set the pivot.

/**
* BitmapText objects work by taking a texture file and an XML or JSON file that describes the font structure.
* It then generates a new Sprite object for each letter of the text, proportionally spaced out and aligned to
* match the font structure.
*
* BitmapText objects are less flexible than Text objects, in that they have less features such as shadows, fills and the ability
* to use Web Fonts, however you trade this flexibility for rendering speed. You can also create visually compelling BitmapTexts by
* processing the font texture in an image editor, applying fills and any other effects required.
*
* To create multi-line text insert \r, \n or \r\n escape codes into the text string.
*
* If you are having performance issues due to the volume of sprites being rendered, and do not require the text to be constantly
* updating, you can use BitmapText.generateTexture to create a static texture from this BitmapText.
*
* To create a BitmapText data files you can use:
*
* BMFont (Windows, free): http://www.angelcode.com/products/bmfont/
* Glyph Designer (OS X, commercial): http://www.71squared.com/en/glyphdesigner
* Littera (Web-based, free): http://kvazars.com/littera/
*
* For most use cases it is recommended to use XML. If you wish to use JSON, the formatting should be equal to the result of
* converting a valid XML file through the popular X2JS library. An online tool for conversion can be found here: http://codebeautify.org/xmltojson
*
* If you were using an older version of Phaser (< 2.4) and using the DOMish parser hack, please remove this. It isn't required any longer.

/**
* A TileSprite is a Sprite that has a repeating texture. The texture can be scrolled and scaled independently of the TileSprite itself.
* Textures will automatically wrap and are designed so that you can create game backdrops using seamless textures as a source.
*
* TileSprites have no input handler or physics bodies by default, both need enabling in the same way as for normal Sprites.
*
* You shouldn't ever create a TileSprite any larger than your actual screen size. If you want to create a large repeating background
* that scrolls across the whole map of your game, then you create a TileSprite that fits the screen size and then use the `tilePosition`
* property to scroll the texture as the player moves. If you create a TileSprite that is thousands of pixels in size then it will
* consume huge amounts of memory and cause performance issues. Remember: use `tilePosition` to scroll your texture and `tileScale` to
* adjust the scale of the texture - don't resize the sprite itself or make it larger than it needs.
*
* An important note about texture dimensions:
*
* When running under Canvas a TileSprite can use any texture size without issue. When running under WebGL the texture should ideally be
* a power of two in size (i.e. 4, 8, 16, 32, 64, 128, 256, 512, etch pixels width by height). If the texture isn't a power of two
* it will be rendered to a blank canvas that is the correct size, which means you may have 'blank' areas appearing to the right and
* bottom of your frame. To avoid this ensure your textures are perfect powers of two.
*
* TileSprites support animations in the same way that Sprites do. You add and play animations using the AnimationManager. However
* if your game is running under WebGL please note that each frame of the animation must be a power of two in size, or it will receive
* additional padding to enforce it to be so.

/**
* Phaser has one single cache in which it stores all assets.
*
* The cache is split up into sections, such as images, sounds, video, json, etc. All assets are stored using
* a unique string-based key as their identifier. Assets stored in different areas of the cache can have the
* same key, for example 'playerWalking' could be used as the key for both a sprite sheet and an audio file,
* because they are unique data types.
*
* The cache is automatically populated by the Phaser.Loader. When you use the loader to pull in external assets
* such as images they are automatically placed into their respective cache. Most common Game Objects, such as
* Sprites and Videos automatically query the cache to extract the assets they need on instantiation.
*
* You can access the cache from within a State via `this.cache`. From here you can call any public method it has,
* including adding new entries to it, deleting them or querying them.
*
* Understand that almost without exception when you get an item from the cache it will return a reference to the
* item stored in the cache, not a copy of it. Therefore if you retrieve an item and then modify it, the original
* object in the cache will also be updated, even if you don't put it back into the cache again.
*
* By default when you change State the cache is _not_ cleared, although there is an option to clear it should
* your game require it. In a typical game set-up the cache is populated once after the main game has loaded and
* then used as an asset store.

/**
* Adds a Sprite Sheet to the current load queue.
*
* The file is **not** loaded immediately after calling this method. The file is added to the queue ready to be loaded when the loader starts.
*
* To clarify the terminology that Phaser uses: A Sprite Sheet is an image containing frames, usually of an animation, that are all equal
* dimensions and often in sequence. For example if the frame size is 32x32 then every frame in the sprite sheet will be that size.
* Sometimes (outside of Phaser) the term "sprite sheet" is used to refer to a texture atlas.
* A Texture Atlas works by packing together images as best it can, using whatever frame sizes it likes, often with cropping and trimming
* the frames in the process. Software such as Texture Packer, Flash CC or Shoebox all generate texture atlases, not sprite sheets.
* If you've got an atlas then use `Loader.atlas` instead.
*
* The key must be a unique String. It is used to add the image to the Phaser.Cache upon successful load.
*
* Retrieve the file via `Cache.getImage(key)`. Sprite sheets, being image based, live in the same Cache as all other Images.
*
* The URL can be relative or absolute. If the URL is relative the `Loader.baseURL` and `Loader.path` values will be prepended to it.
*
* If the URL isn't specified the Loader will take the key and create a filename from that. For example if the key is "alien"
* and no URL is given then the Loader will set the URL to be "alien.png". It will always add `.png` as the extension.
* If you do not desire this action then provide a URL.
*
* @method Phaser.Loader#spritesheet
* @param {string} key - Unique asset key of the sheet file.
* @param {string} url - URL of the sprite sheet file. If undefined or `null` the url will be set to `<key>.png`, i.e. if `key` was "alien" then the URL will be "alien.png".
* @param {number} frameWidth - Width in pixels of a single frame in the sprite sheet.
* @param {number} frameHeight - Height in pixels of a single frame in the sprite sheet.

* [Shoebox](http://renderhjs.net/shoebox/)
*
* If using Texture Packer we recommend you enable "Trim sprite names".

*
* You can choose to either load the data externally, by providing a URL to an xml file.
* Or you can pass in an XML object or String via the `atlasData` parameter.
* If you pass a String the data is automatically run through `Loader.parseXML` and then immediately added to the Phaser.Cache.
*
* If URLs are provided the files are **not** loaded immediately after calling this method, but are added to the load queue.
*
* The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.
*
* Retrieve the file via `Cache.getImage(key)`. XML files are automatically parsed upon load.
* If you need to control when the XML is parsed then use `Loader.text` instead and parse the XML file as needed.
*
* The URLs can be relative or absolute. If the URL is relative the `Loader.baseURL` and `Loader.path` values will be prepended to it.
*
* If the textureURL isn't specified then the Loader will take the key and create a filename from that.
* For example if the key is "player" and textureURL is null then the Loader will set the URL to be "player.png".
* The same is true for the atlasURL. If atlasURL isn't specified and no atlasData has been provided then the Loader will
* set the atlasURL to be the key. For example if the key is "player" the atlasURL will be set to "player.xml".

/**
* The Sound Manager is responsible for playing back audio via either the Legacy HTML Audio tag or via Web Audio if the browser supports it.
* Note: On Firefox 25+ on Linux if you have media.gstreamer disabled in about:config then it cannot play back mp3 or m4a files.
* The audio file type and the encoding of those files are extremely important. Not all browsers can play all audio formats.
* There is a good guide to what's supported here: http://hpr.dogphilosophy.net/test/
*
* 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.
*
* Mobile warning: There are some mobile devices (certain iPad 2 and iPad Mini revisions) that cannot play 48000 Hz audio.
* When they try to play the audio becomes extremely distorted and buzzes, eventually crashing the sound system.
* The solution is to use a lower encoding rate such as 44100 Hz. Sometimes the audio context will
* be created with a sampleRate of 48000. If this happens and audio distorts you should re-create the context.

/**
* @classdesc
* The ScaleManager object handles the the scaling, resizing, and alignment of the
* Game size and the game Display canvas.
*
* The Game size is the logical size of the game; the Display canvas has size as an HTML element.
*
* The calculations of these are heavily influenced by the bounding Parent size which is the computed
* dimensions of the Display canvas's Parent container/element - the _effective CSS rules of the
* canvas's Parent element play an important role_ in the operation of the ScaleManager.
*
* The Display canvas - or Game size, depending {@link #scaleMode} - is updated to best utilize the Parent size.
* When in Fullscreen mode or with {@link #parentIsWindow} the Parent size is that of the visual viewport (see {@link Phaser.ScaleManager#getParentBounds getParentBounds}).
*
* Parent and Display canvas containment guidelines:
*
* - Style the Parent element (of the game canvas) to control the Parent size and
* thus the Display canvas's size and layout.
*
* - The Parent element's CSS styles should _effectively_ apply maximum (and minimum) bounding behavior.
*
* - The Parent element should _not_ apply a padding as this is not accounted for.
* If a padding is required apply it to the Parent's parent or apply a margin to the Parent.
* If you need to add a border, margin or any other CSS around your game container, then use a parent element and
* apply the CSS to this instead, otherwise you'll be constantly resizing the shape of the game container.
*
* - The Display canvas layout CSS styles (i.e. margins, size) should not be altered/specified as
* they may be updated by the ScaleManager.
*
* @description
* Create a new ScaleManager object - this is done automatically by {@link Phaser.Game}

/**
* A Video object that takes a previously loaded Video from the Phaser Cache and handles playback of it.
*
* Alternatively it takes a getUserMedia feed from an active webcam and streams the contents of that to
* the Video instead (see `startMediaStream` method)
*
* The video can then be applied to a Sprite as a texture. If multiple Sprites share the same Video texture and playback
* changes (i.e. you pause the video, or seek to a new time) then this change will be seen across all Sprites simultaneously.
*
* Due to a bug in IE11 you cannot play a video texture to a Sprite in WebGL. For IE11 force Canvas mode.
*
* If you need each Sprite to be able to play a video fully independently then you will need one Video object per Sprite.
* Please understand the obvious performance implications of doing this, and the memory required to hold videos in RAM.
*
* On some mobile browsers such as iOS Safari, you cannot play a video until the user has explicitly touched the screen.
* This works in the same way as audio unlocking. Phaser will handle the touch unlocking for you, however unlike with audio
* it's worth noting that every single Video needs to be touch unlocked, not just the first one. You can use the `changeSource`
* method to try and work around this limitation, but see the method help for details.
*
* Small screen devices, especially iPod and iPhone will launch the video in its own native video player,
* outside of the Safari browser. There is no way to avoid this, it's a device imposed limitation.
*
* Note: On iOS if you need to detect when the user presses the 'Done' button (before the video ends)
* then you need to add your own event listener
