This will fix the Vulkan orientation when the screen is rotated by having
the compositor do the corrections for us. However, it is suggested in the
Android Vulkan docs that for power reasons it may be better for the app
to get the needed rotation off of the VkAndroidSurface and then manually
adjust for this rotation in the rendering without the compositor doing any
corrections. This is something we can look into a later date as it would
require sending some info back from the VulkanWindowContext back to Skia
about what Matrix should be applied.

For now, the only options are sRGB or WideGamutRGB
Basically, the color option to the gpu config is now of
the form: 8888|srgb[_gamut]|f16[_gamut]
color=8888 still implies legacy behavior
srgb implies 8-bit gamma-correct rendering (via sRGB format)
f16 implies 16-bit gamma-correct rendering (via F16 format)
Either of the last two options can then optionally include
a gamut specifier, either _srgb or _wide.
_srgb selects the (default) sRGB gamut
_wide selects the Adobe Wide Gamut RGB gamut, which is nice
for testing, in that it's significantly wider than sRGB,
so rendering differences are obvious.

skpbench is a benchmarking suite for skps that aims to generate 100%
repeatable results. The initial commit consists of three parts:
skpbench
A minimalist program whose sole purpose is to open an skp file,
benchmark it on a single config, and exit. No tiling, looping, or
other fanciness is used; it just draws the skp whole into a size-
matched render target and syncs the GPU after each draw.
Limiting the entire process to a single config/skp pair helps to keep
the results repeatable.
skpbench.py
A wrapper to execute the skpbench binary with various configs and skps.
It also monitors the output in order to filter out and re-run results
with an unacceptable stddev.
In the future this script will lock down and monitor clocks and
temperatures.
parseskpbench.py
A utility for parsing skpbench output into a spreadsheet.

If a quad a conic intersect only where the end of one
is contained by the convex hull of the other, and the
curve contained by the hull is nearly a straight line,
treating it as a line may move the end point to the
other side of the curve.
Detect this by checking to see if the end point is in
the hull, and if so, continue to subdivide the curve
rather than treating it as a line.
This fixes several existing tests that were disabled
earlier this year.
A typo in SkDCurve::nearPoint() prevented detecting when
the end of a line was nearly touching a curve.
Also fixed concidence a bit to get the second half of
tiger further along.

Attempt to take over all *SAN builds.
MSAN has a lot of coordination required between gn/BUILD.gn and gn_flavor.py.
I'd like to follow up to move more of this into gn/BUILD.gn, to make it easier
to use locally.
The compile steps should be much faster now. We no longer build CMake
and Clang for every run, instead using the clang_linux CIPD package. This
removes the need for all the third_party/externals/llvm/... dependencies.
Similarly, since we're using the clang_linux package, we no longer depend
on Chrome's Clang, and thus no longer need to sync chromium on these bots.
Instead of packaging up MSAN libraries and llvm-symbolizer in the compile
output, I have the test / perf bots also depend on the clang_linux package.
These do not vary from build to build.
No more need for the xsan.blacklist -include hack: Clang, GN, and Ninja
all track changes to xsan.blacklist without our help.
This has the incidental effect of upgrading the compiler used by *SAN
bots from Clang 3.8 to Clang 3.9.

Pathops makes up intersections that it doesn't detect directly,
but do exist. For instance, if a is coincident with b, and
b is coincident with c, then for where they overlap
a is coincident with c.
The intersections are made up in different ways. In a few
places, the t values that are detected are interpolated to
guess the t values that represent invented intersections.
The interpolated t is not necessarily linear, but a linear
guess is good enough if the invented t lies between known
t values.
Additionally, improve debugging.
This passes the extended release test suite and additionally
passes the first 17 levels in the tiger test suite;
previously, path ops passed 7 levels.
The tiger suite is composed of 37 levels in increasing
complexity, described by about 300K tests.

Lessons learned
1. ImageShader (correctly) always compresses (typically via PNG) during serialization. This has the surprise results of
- if the image was marked opaque, but has some non-opaque pixels (i.e. bug in blitter or caller), then compressing may "fix" those pixels, making the deserialized version draw differently. bug filed.
- 565 compressess/decompresses to 8888 (at least on Mac), which draws differently (esp. under some filters). bug filed.
2. BitmapShader did not enforce a copy for mutable bitmaps, but ImageShader does (since it creates an Image). Thus the former would see subsequent changes to the pixels after shader creation, while the latter does not, hence the change to the BlitRow test to avoid this modify-after-create pattern. I sure hope this prev. behavior was a bug/undefined-behavior, since this CL changes that.

2. Getting an OpenGL 3.0 context was never tried.
3. Context creation for ES 3.0 was failing on my machine. Since ES 2.0
looks like the intended version from the surrounding code, I set it to
that. It could be rewritten to use a similar loop as standard OpenGL and
try from the highest version to the lowest.

GrTextureAccess optionally includes an instance, computed from the src
and dst color spaces. In all common cases (no color space for either src
or dst, or same color space for both), no object is allocated.
This change is orthogonal to my attempts to get color space attached to
render targets - regardless of how we choose to do that, this will give
us the source color space at all points where we are connecting src to
dst.
There are many dangling injection points where I've been inserting
nullptr, but I have a record of all of them. Additionally, there are now
three places (the most common simple paths for bitmap/image rendering)
where things are plumbed enough that I expect to have access to the dst
color space (all marked with XFORMTODO).
In addition to getting the dst color space, I need to inject shader code
and uniform uploading for appendTextureLookup and friends.

Most changes stem from working on an examples bracketed
by #if DEBUG_UNDER_DEVELOPMENT // tiger
These exposed many problems with coincident curves,
as well as errors throughout the code.
Fixing these errors also fixed a number of fuzzer-inspired
bug reports.
* Line/Curve Intersections
Check to see if the end of the line nearly intersects
the curve. This was a FIXME in the old code.
* Performance
Use a central chunk allocator.
Plumb the allocator into the global variable state
so that it can be shared. (Note that 'SkGlobalState'
is allocated on the stack and is visible to children
functions but not other threads.)
* Refactor
Let SkOpAngle grow up from a structure to a class.
Let SkCoincidentSpans grow up from a structure to a class.
Rename enum Alias to AliasMatch.
* Coincidence Rewrite
Add more debugging to coincidence detection.
Parallel debugging routines have read-only logic to report
the current coincidence state so that steps through the
logic can expose whether things got better or worse.
More functions can error-out and cause the pathops
engine to non-destructively exit.
* Accuracy
Remove code that adjusted point locations. Instead,
offset the curve part so that sorted curves all use
the same origin.
Reduce the size (and influence) of magic numbers.
* Testing
The debug suite with verify and the full release suite
./out/Debug/pathops_unittest -v -V
./out/Release/pathops_unittest -v -V -x
expose one error. That error is captured as cubics_d3.
This error exists in the checked in code as well.

Make a clearer demarcation between shaping and layout.
also: refactor using_skia_and_harfbuzz; stop leaking
like a sieve.
