For V3D, the HW will interpolate slightly differently along the shared edge of the trifan. The conformance tests manage to catch this in the nearest_consistency_* group. To get interpolation to match, we need the last vertex of the triangle to be shared. I first tried implementing draw_rectangle to do triangles instead, but that was quite a bit (147 lines) of code duplication from u_blitter, and this seems much simpler and less likely to break as u_blitter changes. Fixes dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_* on V3D. Reviewed-by: Marek Olšák <marek.olsak@amd.com>
