Mixed samples is no longer relevant for Ganesh. DMSAA and the new
Ganesh architecture both rely on full MSAA, and any platform where
mixed samples is supported will ultimately not use the old

C++ algorithms have largely standardized on a [begin, end) half-open
range, as seen in standard library containers. SkTQSort now adheres to
this model, and takes vec.begin() and vec.end() as its inputs.
To avoid confusion between inclusive and half-open ranges inside the
implementation, internal helper functions now take "left" and "count"
arguments instead of "left"/"right" or "begin"/"end". This avoids any
ambiguity.
(Although performance was not the main goal, this CL appears to
slightly improve our sorting benchmark on my machine.)

Ambiguity has come up re: what "tessellation" means in Ganesh. I
believe that, in the context of a graphics library, "tessellation"
should refer to the hardware pipeline feature of submitting patches

that triangulate things on the CPU to call it "triangulation".

This keeps an alias so code keeps building.

Implements a simple first pass for a path renderer that uses the
classic Red Book "stencil then cover" method, and linearizes curves
with GPU tessellation shaders.
The new path renderer is disabled by default, and can only be enabled
in the viewer UI or by passing the "--pr gtess" flag.

There was never a need to distinguish between "all" and "default".
We can just use kDefalut everywhere. And as we add new path renderers,
we can exclude them from kDefault until they are ready to ship.

We need to specify attribute locations and (sometimes) frag shader
output locations. Desktop GL worked fine without this, but Flutter
ran into this problem, and a Pixel 2 reproduced the issue.
Note that both APIs (BindFragDataLocation and BindAttribLocation)
don't take effect until the next time the program is linked, so
we have to relink the program after applying those changes.
I was afraid that re-linking would eliminate the perf benefits of
pre-compiling the shaders, but (at least on Pixel 2) that's not
the case. I traced the life of a single program, and the initial
link (during precompile) was 4.4 ms. The re-link took 0.23 ms.

The client can do a test run of their application with
a persistent cache set to SkSL mode. They store the key
and data blobs that are produced.
Ship those blobs with the application. At startup, call
GrContext::precompileShader for each key/data pair. This
compiles the shaders, and stores the GL program ID, plus
a small amount of metadata in our runtime program cache.
Caveats:
* Currently only implemented for the GL backend. Other
backends will require more metadata to do any useful
amount of work. Metal may need a more drastic workflow
change, involving offline compilation of the shaders.
* Currently only implemented for cached SkSL (not GLSL
or program binaries). Supporting other formats again
requires more metadata, and the cached shaders become
increasingly specialized to GPU and driver versions.
* Reusing the cached SkSL on different hardware is not
supported. Many driver workarounds are implemented in
the SkSL -> GLSL transformation, but some are higher
level. Limiting device variance by artificially hiding
extensions may help, but there are no guarantees.
* The 'gltestprecompile' DM config exercises this code
similarly to 'gltestpersistentcache', ensuring that
results are visually identical when precompiling, and
that no cache misses occur after precompiling.
