This removes a lot of CPU overhead for the most common case.

Vinson, this test seems to pass for me with current Mesa (fe2f5cfdc7). Can you re-test and close this if it's OK for you?
(In reply to Brian Paul from comment #1) > Vinson, this test seems to pass for me with current Mesa (fe2f5cfdc7). Can > you re-test and close this if it's OK for you? Retested with Mesa 17.3.0-devel (git-63e79a8a77) and 'gl-1.0-scissor-offscreen -fbo -auto' still fails.
OK, I must have had something wrong. I see the issue. Patch posted to mesa-dev for review.
Fixed w/ commit 88cdf16871a0f1cd8ec3844072051ee38e945600
