// There are two levels of delegation in this file:

//   1. GLES2Context delegates to GLES2ContextInternal. This is done

//

//   2. GLES2ContextInternal delegates to an implementation of

//      WebGLES2Context. This is done so we have a place to inject an

//      implementation which creates the GL ES context.
