Reland "Improve scissor state tracking in GrRTC"
This reverts commit 4926b07217f07e8f5ff1dba15d23bab960ffded3.
Reason for revert: fix wip
Original change's description:
> Revert "Improve scissor state tracking in GrRTC"
>
> This reverts commit 3b923a880bc0855772daffd95b5728795f515d5f.
>
> Reason for revert: GrAppliedHardClip isn't tracking scissor state properly
>
> Original change's description:
> > Improve scissor state tracking in GrRTC
> >
> > At a low level, this changes GrScissorState from a rect+bool to a rect+size.
> > The scissor test is considered enablebd if the rect does not fill the
> > device bounds rect specified by the size. This has a number of benefits:
> >
> > 1. We can always access the scissor rect and know that it will be
> > restricted to the render target dimensions.
> > 2. It helps consolidate code that previously had to test the scissor rect
> > and render target bounds separately.
> > 3. The clear operations can now match the proper backing store dimensions
> > of the render target.
> > 4. It makes it easier to reason about scissors applying to the logical
> > dimensions of the render target vs. its backing store dimensions.
> >
> > Originally, I was going to have the extra scissor guards for the logical
> > dimensions be added in a separate CL (with the cleanup for
> > attemptQuadOptimization). However, it became difficult to ensure correct
> > behavior respecting the vulkan render pass bounds without applying this
> > new logic at the same time.
> >
> > So now, with this CL, GrAppliedClips are sized to the backing store
> > dimensions of the render target. GrOpsTasks also clip bounds to the
> > backing store dimensions instead of the logical dimensions (which seems
> > more correct since that's where the auto-clipping happens). Then when
> > we convert a GrClip to a GrAppliedClip, the GrRTC automatically enforces
> > the logical dimensions scissor if we have stencil settings (to ensure
> > the padded pixels don't get corrupted). It also may remove the scissor
> > if the draw was just a color buffer update.
