There is something very strange going on, because I cannot see any
difference between how create_from_gl_buffer and create_from_gl_texture are
declared, and yet:
seanl@michiru ~/project/voxel (git)-[master] % python noisetest.py
Traceback (most recent call last):

There is, however, a mangled version of create_from_gl_texture, and NOT for
create_from_gl_buffer:
