PS1 is the exact contents of src/gpu/v1/ClipStack.* copied to
experimental/graphite/src.
PS2+ shows all the changes to remove v1-only features and update some of
the types over to what graphite uses. The major changes are:
1. FragmentProcessors, clip atlases, stencil mask writing, and SW mask
writing are gone.
2. SW mask caching and tracking are gone.
3. Graphite is effectively in the "forceAA" mode that the original clip
stack supported. So branches that focused on non-AA, or comparing AA
or handling cases where elements' AA mismatched could all be removed.
4. Updated to use Graphite's Shape and Transform classes. Did not go as
far as moving the bounds from SkIRect to Rect, but since everything
is AA, it will be much simpler to switch to comparing float bounds
directly and not worry about rounding in or out. That's a more
substantial change so will come later.
5. The original ClipStack had a "Draw" type that was used to compute
clip interactions between SaveRecords and Elements. It was always
just device-space bounds because of limitations of the GrClip API.
In Graphite, we can use the exact same set of info for Draws and
Elements, making interaction tests share code and be more accurate.
Since that's a more involved change, I just removed the simpler Draw
type from this version for now.
6. Tried to add TODOs for what logic and extra state will need to be
added to actually apply graphite's clip stack as depth-only draws.

Make SkSurface_Raster, draw to it
snap an image, A, from the surface
make image B by calling withDefaultMipmaps() on image A
Let image A be destroyed.
draw to surface again
snap another image, C, from the surface
Image C and image B would now share the same SkPixelRef, reflecting
the final contents of the SkSurface.
Add a GM that exercises the bug when run through either the pic- or

SkSL::Operator was previously just a thin wrapper around Token::Kind and
everything was therefore written in terms of Token. Since Token is not
accessible from include/ (and we don't want it to be), this creates an
actual Operator enum and eliminates the dependence on Token. This will
enable followup changes to reference Operator from within the DSL
include files.

The current setup for the iOS simulator keys off of the fact that iOS
runs on ARM CPUs, and Macs (prior to M1) ran on x64 CPUs. So setting
the target_os to "ios" and the target_cpu to "x64" will indicate use
of the simulator. On M1, they have the same CPU architecture, so we
need another method to indicate use of the simulator SDK.
Also added a check to disable code signing, which is not needed for
running on the simulator.

Because these tasks use RBE, the machines they run on do not

the build steps be a hit on the remote-cache, so we don't need
