There is a certain overlap between this test and test_[fractional_]viewport. This test explicitly tests which fragment lights up and how diagonals that are hit by two triangles are handled, whereas test_viewport checks for a mismatch between fragment location and position of that fragment inside the triangle. Both tests are worth having IMO.
I'll port it to ddraw-d3d11 once the merits of the test and geometry nudge have been agreed upon. --- dlls/d3d9/tests/visual.c | 487 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 487 insertions(+)
