But we should then support flatshade_first somewhere else.
The GL rule is last vertex last for each primitive. The D3D rule is first vertex first. My idea is to have draw_decompose_tmp.h use a local variable, last_vertex_last, to select the rules. In draw_gs_tmp.h and draw_so_emit_tmp.h, last_vertex_last is TRUE when the new settable flags is TRUE. However, in draw_pt_decompse.h, where the rules no longer matter, last_vertex_last is set to !(flatshade && flatshade_first). As for draw_pt_vcache_tmp.h, I am considering removing it and make vcache look more like varray except with index buffer buffer. I will try to work out the idea soon. > need it for clipping anyway.
