As you'll see from the BUG line, we have a strong indication that the new Sk4px
methods regress some devices. This restores the old code back as literally as possible
while still fitting in SkOpts framework.
This is ideally temporary breathing room.
We should get an early indication of if those bugs will improve by watching https://perf.skia.org/#4004

crbug.com/526025 includes a minimized SVG test case.
Translating that test case into native code (fuzzTNG)
did not reproduce the bug. That test case should
have not been included with skia issue 1323813003,
and is deleted here.
Running the minimal test case in a modified version
of chrome isolated the bug. The modified version
generated the test fuzz763_3 with the edit
#define DEBUGGING_PATHOPS_FROM_HOST 1
in src/pathops/SkPathopsOp.cpp line 188.
Rename fuzz763_3 to issue_526025 to associate the test
with the bug. Note that the bug contains the body of the
CL in comment $5.

This, at least, makes GrTextContexts no longer bound to a single GrDrawContext. (Passing in a RenderTarget and praying it matched the DrawContext was always a bit fishy too).

This switches over SkXfermodes_opts.h and SkColorMatrixFilter to use Sk4f,
and converts the SkPMFloat benches to Sk4f benches.
No pixels should change here, and no code beyond the Sk4f_ benches should change speed.
The benches are faster than the old versions.

This lets us avoid conversions to [0.0, 1.0] space and rounding that aren't necessary
for SkColorCubeFilter_opts.h.
Dropping rounding on the way back to bytes means we'll see a bunch of off-by-1 diffs.
Rough perf effect:
SSSE3: 110 -> 93 (~15%)
NEON: 465 -> 375 (~20%)
This is the beginning of the end for SkPMFloat as an entity distinct from Sk4f.
I've kept it for now so I can convert sites one by one and think about how things
that really want to keep PM color order will work.

It is easy to think in some cases that SkString::resize(int) is not
destructive, since optimizations mean that most of the time the data
is still there after a resize. However, in the general case, the
original string's data is lost and the new SkString contains garbage.

Vertex counts are always exact, so don't bother handling the case
where they're different. Just assert.
Rename variables to reflect.

The list of intersection points on a curve segment may have
entries that can be safely removed when nearby points have
nearly the same t value and point value. When a path includes
very large curves as well as small ones, as is the case with
this fuzzer, additional points may lie between the similar
points that do not meet the nearby criteria.
After merging the nearby point with its doppelganger,
SkOpSegment::moveNearby() unnecessarily set the doppelganger's
next pointer to the one following the nearby point. While
this usually has no effect, since the merge already updated
the linked list, the explicit call removes the additional
outlier points from the segment.

The million SKPs generated require >5T of storage. A good deal
of that are copies of system fonts.
Chrome built with
#DEFINE SK_WHITELIST_SERIALIZED_TYPEFACES
will omit the font data if the font matches a precomputed
checksum.
The captured SKP prepends sk_ to the names of fonts that
have their data omitted. The SKP consumer can either add
renamed fonts from the recording machine, or add
gDeserializeTypefaceDelegate = WhitelistDeserializeTypeface;
which strips the sk_ prefix when deserializing typefaces.
whitelist_typefaces --check
Computes the checksums of fallback
fonts and returns 0 if the checksums match the checked-in
file SkWhitelistChecksum.cpp.
whitelist_typefaces --generate
Writes an updated version of SkWhitelistChecksum.cpp.

Redesigns SkScanlineDecoder.h to indicate the ordering
in which the scanlines are provided
Refactors SkSwizzler::Fill() to include the zeroInit check
and to actually be correct.
