2010-05-05gallium: rework provoking vertex codeBrian Paul
Builds on commit ddb0e18f6c5582d4d2cc59ffd16ad9c4639ed059 and fixes regressions in glean clipFlat test. We assume that Gallium drivers observe flatshade_first for all triangles and that all the assorted per-triangle calls in the 'draw' module also follow flatshade_first. Everything else builds on those rules. Gallium does not use follow flatshade_first for GL quads, quad strips and polygons; the "last" vertex is always the provoking vertex for those prims. So now there are separate QUAD_FIRST_PV and QUAD_LAST_PV macros in the draw primitive decomposition code instead of one QUAD macro.

Based on John Lawless' feedback.
