 * @classdesc
 * WebGLRenderer is a class that contains the needed functionality to keep the
 * WebGLRenderingContext state clean. The main idea of the WebGLRenderer is to keep track of
 * any context change that happens for WebGL rendering inside of Phaser. This means
 * if raw webgl functions are called outside the WebGLRenderer of the Phaser WebGL
 * rendering ecosystem they might pollute the current WebGLRenderingContext state producing
 * unexpected behavior. It's recommended that WebGL interaction is done through
 * WebGLRenderer and/or WebGLPipeline.
