Coordinate systems on on nv10-era cards
...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 projection
matrix sent t...
