This causes the glean clipFlat test to fail with softpipe. The gallium softpipe driver _does_ implement the "quad follows provoking vertex" convention. I don't have time right now to update the softpipe driver so this patch will have to wait a while. Maybe someone else can look at it sooner. -Brian ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
