This begs a question or two:

1) why does Mesa not barf on NULL textures to glTexImage2D()?

... Looking at the source it seems this is allowed.

2) where does the spec spell out when NULL pointers should or should
not generate errors

Daniel and I looked in the Red and Blue books, and the Spec, but
didn't see anything, offhand.
