* It can still rotate, scale, crop and receive input events. This makes it perfect for logos, backgrounds, simple buttons and other non-Sprite graphics.
*
* @constructor
* @param {Phaser.Game} game - A reference to the currently running game.
* @param {number} x - The x coordinate of the Image. The coordinate is relative to any parent container this Image may be in.
* @param {number} y - The y coordinate of the Image. The coordinate is relative to any parent container this Image may be in.
* @param {string|Phaser.RenderTexture|Phaser.BitmapData|PIXI.Texture} key - The texture used by the Image during rendering. It can be a string which is a reference to the Cache entry, or an instance of a RenderTexture, BitmapData or PIXI.Texture.
