Running:

print 'Max texture image units ', glGetInteger(GL_MAX_TEXTURE_IMAGE_UNITS)

Produces the following error:

Message:
Wow, there were a *lot* of bugs hiding behind that one.  Any non-extension
glGet constant over about GL 1.1 was going to raise an error.  I've updated
the code to have all GL 2.1 constants, but there's going to be 3.0, 3.1 and
3.2 constants missing.  Need to get a better mechanism for determining what
can be used with glGet to make this automatic.

3.0.1 should have the fix for the particular bug here.
