To attempt to work around this, I've moved all of PyOpenGL to using a 
pattern where entry points are resolved only when they are first used. 
If I'm right about what Optimus is doing, that *should* give us the 
right entry points, as they should be looked up in the context after 
Optimus has swapped them out for its own entry points.

No way to tell without actually testing, though.

Thanks,
Mike
