As it stands, this would begin advertising the ARB_texture_buffer_object
extension on 3.1.  I don't think we want to do that, since the extension
specs luminance/alpha bits, and we don't support those.

If you changed ARB_texture_buffer_object to GLL in extensions.c, I would
be fine with this change.
