 * Registers canvases with Canvas2DRenderingContexts and renders them
 * all in the same WebGLRenderingContext, spitting out textures to apply
 * to the canvases. Creates a fullscreen WebGL canvas that is not added
 * to the DOM, and on each frame, renders each registered canvas on a portion
 * of the WebGL canvas, and applies the texture on the registered canvas.
 *
 * In the future, can use ImageBitmapRenderingContext instead of
 * Canvas2DRenderingContext if supported for cheaper transfering of
 * the texture.
