/**
 * @classdesc
 * A Texture Source is the encapsulation of the actual source data for a Texture.
 * This is typically an Image Element, loaded from the file system or network, or a Canvas Element.
 *
 * A Texture can contain multiple Texture Sources, which only happens when a multi-atlas is loaded.
 *
 * @class TextureSource
 * @memberOf Phaser.Textures
 * @constructor
 * @since 3.0.0
 *
 * @param {Phaser.Textures.Texture} texture - The Texture this TextureSource belongs to.
 * @param {(HTMLImageElement|HTMLCanvasElement)} source - The source image data.
 * @param {integer} [width] - Optional width of the source image. If not given it's derived from the source itself.
 * @param {integer} [height] - Optional height of the source image. If not given it's derived from the source itself.
