Well, as of right now, ES and EGL are just spike tests in PyOpenGL. Once 
they are working, it sounds like it might be possible to make ANGLE 
work.  You'd need a layer that enabled ANGLE in your application, it 
looks like it basically just has some EGL entry points that let you 
connect to a Win32 Direct3D context... so you likely need some stubs to 
make that context available before you start doing the EGL operations.  
It doesn't really seem like something that should be *in* PyOpenGL, 
though.  That is, you'd expect to see the EGL, and OpenGL-ES code in 
PyOpenGL and then a small shim that worked with ANGLE (likely having to 
deliver the ANGLE libraries with it).

HTH,
Mike
