Yeah, I'd say all except the first test are wrong. When you draw a
flipped region, the flipping should be done last, not first.
I don't want to fix it right now... still trying to figure out what's
wrong with transformations. The patch Trent applied (and then reverted)
was correct. However things break with it. So I guess there's some flaw
with how our transformations are applied to OpenGL.
