* @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
* @extends PIXI.Sprite
* @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.
