Conics with very large w values can
be approximated with two straight lines.
This avoids iterating endlessly in an
attempt to create quadratics with unstable
numerics.
Check to see if the first chop generated
a pair of lines within the default
point comparison tolerance.

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.

HWUI skips transparent rects when drawing.
When skia draws using bilerp, we will blend
transparent rects with neighboring rects and might
draw a bit of a smudge.
This CL adds the option to skip rects, allowing us
to have compatible behavior with the framework.

In our current setup, there is no need for storing the sampled images in an
array and then putting in barriers for them later. If we ever change the
system to building up these secondary command buffers early, we will need
to go back to storing the sampled images.

I think is a good redesign that will allow us to handle more png
xforms more efficiently. And I also think it reduces a bit of
complexity.
PNGs can be RGBA, RGB, Gray, GrayAlpha, Index8.
The swizzler handles all of those input formats and all Skia
output formats. Swizzler also provides sampling/subsetting.
Color xforms currently only handles RGBA. So we use the
swizzler to convert to RGBA first. I've started thinking
about adding RGB, Gray, etc. support for color xforms.
In this case (and the RGBA case), we should skip the
swizzling step.

I am hoping this makes it easier to get *SAN bots going.
Today we're generating a libcompiler_rt.a that's using a
relocation type that the ld on the bots doesn't know about.
This lld is will know about anything our Clang generates.

The remaining suppression (libwebp) is already covered by the

This file will be imported by Chrome to access the sources lists.
Once Chrome is updated to use this file, changes to the skia .gypi layout can
be done entirely within the skia repository as long as the resulting lists
produced by the new .gni file have the same name.
Marks skia_for_chromium_defines as obsolete and moves the definition into the new .gni file. We can remove the .gypi file when Chrome is updated.

'static const' means, there must be at most one of these, and initialize it at
compile time if possible or runtime if necessary. This leads to unexpected
code execution, and TSAN* will complain about races on the guard variables.
Generally 'constexpr' or 'const' are better choices. Neither can cause races:
they're either intialized at compile time (constexpr) or intialized each time
independently (const).
This CL prefers constexpr where possible, and uses const where not. It even
prefers constexpr over const where they don't make a difference... I want to have
lots of examples of constexpr for people to see and mimic.
The scoped-to-class static has nothing to do with any of this, and is not changed.
* Not yet on the bots, which use an older TSAN.
