Log Message:
-----------
TexVert sharing was disabled for flat faces, this is silly since a building or
any other model with flat faces will often be able to share texverts.
Simple testcase with a subdivided cube used 1/3 as many texverts and spend half
as much time in the rasterizer while profiling.
