Well it's a somewhat advanced feature because it's only required by GL
3.3, and the functionality is not present in DX10.
Personally I'm not really against requiring drivers to implement this
(though I'd like to hear more opinions), however whoever introduces this
feature should then also try to unbreak the drivers.
