From now on, sample counts always refer to the number of actual color
samples, and render targets don't have separate color and stencil
sample counts.
If mixed samples support is available when making a
"GrAAType::kCoverage" draw, then an op may attach and use a mixed
sampled stencil buffer internally. But this will all be invisible to
the client.
After this CL, we temporarily won't have a mode to use nvpr with mixed
samples. That will soon be fixed by a follow-on CL that enables nvpr
with mixed samples in the normal "gl" and "gles" configs.

- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout

Removes the notion of a stashed atlas that we store from the previous

can either be 16-bit or 8-bit.
The "reuse" and "animation" cases should both behave exactly the same

The main difference is that cases like tiled rendering now work. If

cached atlas, just like the "stashed atlas" implementation. But if you
draw your scene in tiles, you now get lots of little cached 16-bit

2) On subsequent flushes, check the stashed atlas to see if we can
reuse any of its cachable paths. Copy reusable paths into 8-bit
literal coverage atlases and store them in the resource cache.
3) Recycle the stashed atlas texture for the remaining paths in the

This is pretty much a straight up move of the GrSurfaceProxy code with some plumbing to get the ProxyProvider in the right places.

Adds Qualcomm to the set of GL devices on which we prefer fullscreen
clears.
Renames fullscreenClearIsFree in GrCaps to preferFullscreenClears.
Replaces 'bool canIgnoreClip' on GrRenderTargetContext::clear with an
enum.

Points cost 8 bytes and indices cost 4. If a point is accessed twice,
it's a wash whether we duplicate it or index. This change eliminates
texel buffers by duplicating points across instance arrays. This
reduces our dependence on extensions as well as getting rid of our
indirect memory access pattern in vertex shaders.
As a result of this change, memory usage by GPU buffers will only be a
fraction larger at worst, and slightly better at best.

Transforms a path's points into a local buffer up front, rather than
transforming as we parse. This hopefully gets better vector
performance as well as allowing us to skip the transformation step
for paths that are known to be in device space already.
Introduces a test for parsing empty paths and does general cleanup.
