+// There are two levels of delegation in this file:
+//
+//   1. GLES2Context delegates to GLES2ContextInternal. This is done
+//      so that we have some place to store data members common among
+//      implementations.
+//
+//   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.
