Please find attached my test program. I guess I can only point that
above call is not mentioned in OpenGL 2.0 specification:
There is really great deal of confusion regarding what actually
constitutes OpenGL 2.0, hopefully upcoming Mesa 7.0 release (that will
advertise OpenGL 2.1 support) will stabilize these things...
Anyway, kudos for your great work on PyOpenGL!
