This matter won't go away if we ignore it. We will never get full OpenGL
3.0+ compliance if we don't merge in the floating branch.

Attached you will find a patch against Marek's floating branch to hide
the patented extensions behind a configure switch. Please ACK if you
think we could merge in floating or give some opinion why you think we
couldn't merge.
