--- Comment #21 from Henri Verbeet hverbeet@gmail.com 2009-08-26 06:03:12 --- That's what Fabian's patch does, although only for a limited number of cases. I'm not necessarily opposed to such a patch, but it would have to be done properly, and I'm not sure if that's worth the effort. EXT_provoking_vertex should be trivial to implement for drivers, and the amount of applications affected by this is rather limited.
