/**
 * @classdesc
 * BitmapMaskPipeline handles all bitmap masking rendering in WebGL. It works by using
 * sampling two texture on the fragment shader and using the fragment's alpha to clip the region.
 * The config properties are:
 * - game: Current game instance.
 * - renderer: Current WebGL renderer.
 * - topology: This indicates how the primitives are rendered. The default value is GL_TRIANGLES.
 *              Here is the full list of rendering primitives (https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Constants).
 * - vertShader: Source for vertex shader as a string.
 * - fragShader: Source for fragment shader as a string.
 * - vertexCapacity: The amount of vertices that shall be allocated
 * - vertexSize: The size of a single vertex in bytes.
 *
 * @class BitmapMaskPipeline
 * @extends Phaser.Renderer.WebGL.WebGLPipeline
 * @memberOf Phaser.Renderer.WebGL.Pipelines
 * @constructor
 * @since 3.0.0
 *
 * @param {object} config - Used for overriding shader an pipeline properties if extending this pipeline.
