The spec gives a small list of things that can occur inside a Begin/End
block. In the 3.0 spec, these commands are listed in section 2.6.3.
Only commands that set immediate mode vertex data are allowed. Nothing
that sets or gets state is allowed.
In any case, thanks for fixing this and the UseProgram bug.
