/**
 * @classdesc
 * Experimental WebGL vector renderer. Supports polygons, lines and points:
 *  Polygons are broken down into triangles
 *  Lines are rendered as strips of quads
 *  Points are rendered as quads
 *
 * You need to provide vertex and fragment shaders as well as custom attributes for each type of geometry. All shaders
 * can access the uniforms in the {@link module:ol/webgl/Helper~DefaultUniform} enum.
 * The vertex shaders can access the following attributes depending on the geometry type:
 *  For polygons: {@link module:ol/render/webgl/PolygonBatchRenderer~Attributes}
 *  For line strings: {@link module:ol/render/webgl/LineStringBatchRenderer~Attributes}
 *  For points: {@link module:ol/render/webgl/PointBatchRenderer~Attributes}
 *
 * Please note that the fragment shaders output should have premultiplied alpha, otherwise visual anomalies may occur.
 *
 * Note: this uses {@link module:ol/webgl/Helper~WebGLHelper} internally.
