Revert "Vulkan: Use specialization constant for halfRenderAreaWidth" This reverts commit ff38106d62fca2e36ec2db1cd580b546fd53ae43. Reason for revert: Suspect that this CL may be causing win-angle-rel-32 bot failures Original change's description: > Vulkan: Use specialization constant for halfRenderAreaWidth > > halfRenderArea is used by fragment shader to adjust gl_FragCoord for > rotation and yflip compensation. This CL bakes halfRenderAreaWidth into > shader via specialization constant, thus allow compiler to consolidate > the calculation into one MAD instruction. > > Bug: b/173800146 > Change-Id: Id66301278e3389e2582369b695825e632bccecee > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2551541 > Commit-Queue: Charlie Lao <cclao@google.com> > Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> > Reviewed-by: Tim Van Patten <timvp@google.com> > Reviewed-by: Jamie Madill <jmadill@chromium.org> TBR=timvp@google.com,syoussefi@chromium.org,jmadill@chromium.org,cclao@google.com # Not skipping CQ checks because original CL landed > 1 day ago.
