[Mesa-dev] [PATCH] i965 gen6: Fix transform feedback of triangle strips.

2011-12-23 Thread Paul Berry
When rendering triangle strips, vertices come down the pipeline in the order specified, even though this causes alternate triangles to have reversed winding order. For example, if the vertices are ABCDE, then the GS is invoked on triangles ABC, BCD, and CDE, even though this means that triangle BC
