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.
