*
* Phaser - http://phaser.io
*
* v2.0.6 "Jornhill" - Built: Wed Jun 11 2014 14:38:21
*
* 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.
*

/**
 A RenderTexture is a special texture that allows any pixi displayObject to be rendered to it.

 __Hint__: All DisplayObjects (exmpl. Sprites) that render on RenderTexture should be preloaded.
 Otherwise black rectangles will be drawn instead.

 RenderTexture takes snapshot of DisplayObject passed to render method. If DisplayObject is passed to render method, position and rotation of it will be ignored. For example:

    var renderTexture = new PIXI.RenderTexture(800, 600);
    var sprite = PIXI.Sprite.fromImage("spinObj_01.png");
    sprite.position.x = 800/2;

    sprite.anchor.x = 0.5;
    sprite.anchor.y = 0.5;
    renderTexture.render(sprite);

 Sprite in this case will be rendered to 0,0 position. To render this sprite at center DisplayObjectContainer should be used:

    var doc = new PIXI.DisplayObjectContainer();
    doc.addChild(sprite);
    renderTexture.render(doc);  // Renders to center of renderTexture

*
* 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.

*
* * 'Over' - when the Pointer moves over the Button. This is also commonly known as 'hover'.
* * 'Out' - when the Pointer that was previously over the Button moves out of it.
* * 'Down' - when the Pointer is pressed down on the Button. I.e. touched on a touch enabled device or clicked with the mouse.
* * 'Up' - when the Pointer that was pressed down on the Button is released again.
*
* You can set a unique texture frame and Sound for any of these states.
*
* @constructor
* @extends Phaser.Image
*
* @param {Phaser.Game} game Current game instance.
* @param {number} [x=0] - X position of the Button.
* @param {number} [y=0] - Y position of the Button.
* @param {string} [key] - The image key as defined in the Game.Cache to use as the texture for this Button.
* @param {function} [callback] - The function to call when this Button is pressed.
* @param {object} [callbackContext] - The context in which the callback will be called (usually 'this').
* @param {string|number} [overFrame] - This is the frame or frameName that will be set when this button is in an over state. Give either a number to use a frame ID or a string for a frame name.
* @param {string|number} [outFrame] - This is the frame or frameName that will be set when this button is in an out state. Give either a number to use a frame ID or a string for a frame name.
* @param {string|number} [downFrame] - This is the frame or frameName that will be set when this button is in a down state. Give either a number to use a frame ID or a string for a frame name.

    * Checks for collision between two game objects. You can perform Sprite vs. Sprite, Sprite vs. Group, Group vs. Group, Sprite vs. Tilemap Layer or Group vs. Tilemap Layer collisions.
    * The second parameter can be an array of objects, of differing types.
    * The objects are also automatically separated. If you don't require separation then use ArcadePhysics.overlap instead.
    * An optional processCallback can be provided. If given this function will be called when two sprites are found to be colliding. It is called before any separation takes place,
    * giving you the chance to perform additional checks. If the function returns true then the collision and separation is carried out. If it returns false it is skipped.
    * The collideCallback is an optional function that is only called if two sprites collide. If a processCallback has been set then it needs to return true for collideCallback to be called.
    * NOTE: This function is not recursive, and will not test against children of objects passed (i.e. Groups or Tilemaps within other Groups).
