Summary: regression: multitexturing broken in 3.0.0

Initial Comment:
I've been trying to track down a regression in multitexturing that happens on Windows with PyOpenGL3. I get the same issue with Python2.5 and Python2.6, and it goes away when I test on Python2.5 with PyOpenGL 2.0.2.01. I don't get this error on Linux.

Running the old NeHe demo "lesson6-multi.py" I found in a local copy of PyOpenGL-2.0.1.09 (in PyOpenGL-2.0.1.09/OpenGL/Demo/NeHe/), I get this traceback:

Z:\test>c:\python25\python lesson6-multi.py

Message:
Have just tested with the Demo/NeHe/lesson6-multi.py from PyOpenGL 2.0.1.09
with PyOpenGL 3.0.1 (about to be released).  Works as expected.  We also
have a PyOpenGL-Demo package which includes the updated version of the
demo, which works fine.  We have lots of other scripts that use
multi-texturing, both with the legacy and shader APIs.
