Coordinate systems on on nv10-era cards
...hing to do with the failure, at least it behaves identically when I just return tex instead of copiex_tex. Without any modifications, the test just renders one big red square. I think there's something wrong with the coordinate systems since if I change glColor4fv(red); piglit_draw_rect(0, 0, TEX_WIDTH / 2, TEX_HEIGHT / 2); to instead be piglit_draw_rect(1, 1, TEX_WIDTH / 2, TEX_HEIGHT / 2); Then the result is all black. So I think that the coordinates are being scaled up somewhere they're not supposed to be (or, conversely, not being scaled down when they are supposed to be). The projecti...
