That's a good point Robert,

If the GLContext work that steve and felipe did become an actual thing, 
this would help that cause become cross platform.
Angle also is strictly es2, and I haven't looked at prism es2 in a while 
but I think we use GL2 calls for desktop in some cases. We would have to 
address those cases (if even possible) before any work started.
