I ran into a small typo in the modified FBConfig code:

s/GLX_BIND_TO_TEXTURE_RGB[A]_EXT/GLX_TEXTURE_FORMAT_RGB[A]_EXT

Patch attached.

Other than that, I everything looks fine.  The check for 
SGIX_fbconfig should really be a check for version 1.3 to be 
correct, but that might anger anyone who's GLX provider doesn't 
report 1.3 yet.

Thanks,
