Revert "Vulkan: Generate gl_Position.z correction in SPIR-V" This reverts commit 1e4f8b02ae0603e7034c37e0ff6cee39c38771a9. Reason for revert: Earlier CL breaks pre-rotation: https://chromium-review.googlesource.com/c/angle/angle/+/2598584 Original change's description: > Vulkan: Generate gl_Position.z correction in SPIR-V > > Instead of having the translator output code to transform gl_Position.z > to Vulkan clip space in the vertex stage, this change makes the SPIR-V > transformer perform this operation on the last geometry stage. > > An alternative solution would be to generate this transformation in the > translator in every geometry stage, each controlled by a separate > specialization constant. This change avoids unnecessary modifications > to earlier stages. Additionally, the transformer is already modifying > gl_Position.xy for pre-rotation, so the addition of a small > transformation of gl_Position.z in the same spot is rather trivial. > > Bug: angleproject:5479 > Change-Id: Id971179ba47b206204bfdaf3b2b295ef97dd5117 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2598585 > Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> > Reviewed-by: Charlie Lao <cclao@google.com> > Reviewed-by: Jamie Madill <jmadill@chromium.org> TBR=syoussefi@chromium.org,jmadill@chromium.org,cclao@google.com Change-Id: I3bdf3d6f743125eaf552608f2664b715bd6935c5 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: angleproject:5479 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2634203 Reviewed-by: Tim Van Patten <timvp@google.com> Commit-Queue: Tim Van Patten <timvp@google.com>
