When blitting out of a mask with nine patch, the nine patch code may
call the blitters with a mask row bytes of zero, with the intention of
blitting the same row out of the mask into many rows of the destination.
In D32_A8_Opaque_Color_neon and blit_mask_d32_a8_black when
SK_ARM_HAS_NEON it is assumed that the maskRB >= width. If the maskRB
are less than the width, the maskRB -= width underflows, which is
defined, but the later mask += maskRB is not, as this wil be the
addition of a very large integer to the mask pointer, which is
definitely larger than the mask allocation. In practice on a twos
compliment machine with sizeof(size_t) == sizeof(void*) with a flat
address space this works out, but it is undefined behavior.
When calculating the mask adjustment instead calculate and store it as
ptrdiff_t. After ssa, this is effectively the same code but with a
signed add to the mask pointer instead of unsigned.
Discovered with dm with ASAN (with UBSAN) on arm64 Mac.

The test case was producing a stack trace of sequential path transforms.
While each individual call would check to see if the path is too big
and return, the resulting path kept getting continually bigger as we
transformed it again and then popped the stack. This CL changes it to
skip the transform op if the returned path is already too big.

The GrPathUtils::quadPointCount and cubicPointCount functions take a
tolerance value. The paired generateQuad/CubicPoints functions that will
fill up-to the returned point count from those first questions actually
takes the square of the tolerance value.
This was noticed in https://fiddle.skia.org/c/7e42210ddb6675fe8729c0ba5b07daf5
as the subtle linear artifacts around the rounded corners of the stroke.
GrAAConvexTessellator was not passing in the square value, so the point
generation would early-out sooner than it should have in this example.
Instead of using 16 vertices it used 8. Passing in the square fixes the
linear artifacts when testing locally.
I did an audit of other usages of these functions and SkShadowUtils also
needed to be updated. As part of this, I switched the constants over to
constexpr. The only other user of this function, default path renderer,
did not need to be updated.

Adds a new GM that draws text in an SkPicture, transformed by a
perspective matrix. When drawn directly with drawPicture() it looks
fine. When drawn calculating a scale factor manually from the matrix
and converting to an image (SkImage::MakeFromPicture + drawImageRect),
it looks nearly indistinguishable. However, when drawing using a picture
shader, the image resolution of the cached rasterization is far too low.
Originally, this is because SkPictureShader only relied on
SkMatrix::decomposeScale, which fails if there's perspective and
the picture shader's fallback is to switch to the identity scale. When
the source picture has relatively small local bounds compared to the
final destination, this results in severe sampling artifacts.
This CL switches the fallback to use SkMatrixPriv::DifferentialAreaScale,
which is what was used to compute the manual scale factor in the GM,
and is what image filters use when creating their device's coordinate
space when the canvas has perspective.

Previously, we used a fixed portion of the fuzzer input for uniform
data, and assumed zero children. Now we synthesize uniform and child
inputs based on the needs of the input shader. We no longer need to
reserve the last 256 bytes of each shader for uniform data; a followup
CL will remove the special corpus that this fuzzer used.
The contents of each uniform/child is not particularly important, since
we don't care what the final paint looks like. Each uniform is filled in
with increasing values in each slot, starting at zero (0, 1, 2, 3, ...).
Each child is a simple built-in shader/filter/blender.

This CL adds the task driver and plumbing necessary to run CI tasks that upload build statistics to https://codesize.skia.org.
For now, a single CodeSize-dm-Debian10-Clang-x86_64-Release task is defined, which as the name suggests:
- Depends on Build-Debian10-Clang-x86_64-Release.
- Takes the "dm" binary built by the aforementioned job.
- Runs Bloaty against said binary.
- Uploads the Bloaty output, along with a JSON file with metadata, to the GCS bucket where https://codesize.skia.org gets its data from.
If one wishes to upload codesize statistics for another binary, the steps are as follows:
- Identify the target binary, for example "fm".
- Identify a compile task that builds said binary with the desired settings, for example "Build-Debian10-Clang-x86_64-Debug".
- Add a new job in //infra/bots/jobs.json named "CodeSize-<binary>-<compile task>", where <compile task> is the name of the compile task without the "Build-" prefix, for example "CodeSize-fm-Debian10-Clang-x86_64-Debug".
- Run "make train" from the //infra/bots directory.
Eventually the codesize.skia.org webserver will automatically pick up the output of any such CodeSize-* task and show it in the UI, with no additional steps needed.
One caveat is that the binary file name, and therefore the "<binary>" part of the task name, cannot contain dashes. This is due to how //infra/bots/gen_tasks_logic.go works. See comments in said Go file for ideas on how to work around this if we ever need to.
