* @overview
*
* Phaser - http://www.phaser.io
*
* v1.1.4 - Built at: Wed Feb 05 2014 16:54:13
*
* By Richard Davey http://www.photonstorm.com @photonstorm
*
* A feature-packed 2D HTML5 game framework born from the smouldering pits of Flixel and
* constructed via plenty of blood, sweat, tears and coffee by Richard Davey (@photonstorm).
*
* Phaser uses Pixi.js for rendering, created by Mat Groves http://matgroves.com/ @Doormat23.
*
* Follow Phaser development progress at http://www.photonstorm.com
*
* Many thanks to Adam Saltsman (@ADAMATOMIC) for releasing Flixel, from which both Phaser
* and my love of game development originate.

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

 __Hint__: All DisplayObjects (exmpl. Sprites) that renders 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.position.y = 600/2;
    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

* @class Phaser.Sprite
*
* @classdesc Create a new `Sprite` object. Sprites are the lifeblood of your game, used for nearly everything visual.
*
* At its most basic a Sprite consists of a set of coordinates and a texture that is rendered to the canvas.
* They also contain additional properties allowing for physics motion (via Sprite.body), input handling (via Sprite.input),
* events (via Sprite.events), animation (via Sprite.animations), camera culling and more. Please see the Examples for use cases.
*
* @constructor
* @param {Phaser.Game} game - A reference to the currently running game.
* @param {number} x - The x coordinate (in world space) to position the Sprite at.
* @param {number} y - The y coordinate (in world space) to position the Sprite at.
* @param {string|Phaser.RenderTexture|Phaser.BitmapData|PIXI.Texture} key - This is the image or texture used by the Sprite during rendering. It can be a string which is a reference to the Cache entry, or an instance of a RenderTexture or PIXI.Texture.
* @param {string|number} frame - If this Sprite is using part of a sprite sheet or texture atlas you can specify the exact frame to use by giving a string or numeric index.
