FWIW we ignore these (IMHO silly) version requirements on almost every
extension that has them. I know I've personally added support for
EXT_polygon_offset_clamp into compat contexts, whereas the ext
specifies GL 3.3 minimum.
I'll give it a shot on NVIDIA and see what happens... my tests might
require GL 3.2 because I didn't want to deal with the various
differences that happen otherwise.
