Old flow to serialize a picture:
1) serialize picture ops
2) serialize all sub pictures recursively
3) flatten the rest of this picture into a buffer, deduping flattenable factories and typefaces as we go
4) serialize the factories and typefaces
5) serialize the bytes from 3)
This allows the data in step 5) to refer to the deduplicated factories and typefaces from step 4). But, each sub picture in step 2) is completely siloed, so they can't dedup with the parent picture or each other.
New flow:
1) serialize picture ops
2) flatten the rest of this picture into a buffer, deduping flattenable factories and typefaces as we go
3) dummy-serialize sub pictures into /dev/null, with the effect of adding any new typefaces to our dedup set
4) serialize the factories and typefaces
5) serialize the bytes from 2)
6) serialize all sub pictures recursively, with perfect deduplication because of step 3).
Now all typefaces in the top-level picture and all sub pictures recursively should end up deduplicated in the top-level typeface set.
Decoding changes are similar: we just thread through the top-level typefaces to the sub pictures. What's convenient / surprising is that this new code correctly reads old pictures if we just have each picture prefer its local typeface set over the top-level one: old pictures always just use their own typefaces, and new pictures always use the top-level ones.

In the cases we have come across so far, native scaling has better performance
and correctness than sampling. If native scaling is supported we want to use
it.
Jpegs native scale rounds up.
Ex: An 11x11 image with sampleSize=8 scales to 2x2.
SkScaledCodec rounds down.
Ex: An 11x11 image with sampleSize=8 scales to 1x1.
Before the CL, we would choose to use SkScaledCodec because it scales closer to
the "ideal" scale.
I think we want to go with the native option as long as its within 1 of the
ideal value.

The GrPaint's color takes into account shaders and color filters, so is a
more accurate picture of the color state.

Fixed wrong indent
Changed auto child advance back to backwards linear search for getting subset of coords and samplers array of a child
Used offset from parent instead of backwards linear search to find a child proc's coords and transforms in Auto...Advance
append mangleString to variable name in nameVariable()
BUILDS! Added AutoFragmentChildProcAdvance class; fixed a few errors from previous commits

If a curve has the identical start and control points, the
initial or final tangent can't be trivally determined. The
perpendicular to the tangent is used to measure coincidence.
Add logic for cubics, quadratics, and conics, to use the
secondary control points or the end points if the initial
control point alone can't determine the tangent.
Add debugging (currently untriggered by exhaustive testing)
to detect zero-length tangents which are not at the curve
endpoints.
Increase the number of temporary intersecions gathered from
10 to 12 but reduce the max passed in by cubic intersection from
27 to 12. Also, add checks if the max passed exceeds the
storage allocated.
When cleaning up parallel lines, choose the intersection which
is on the end of both segments over the intersection which
is on the end of a single segment.

It's sort of pointless: all our clients that will have SSE2 at runtime have it
unconditionally at compile time, so the functions in namespace portable will
pick up the SSE2 code. The procs in SkOpts_sse2.o were just duplicate code.
A couple of the procs we had in _sse2.cpp can benefit slightly when compiled
with SSSE3. I've moved those to _ssse3.cpp. This should lead to small speedups
on platforms like Linux and Windows that have a baseline of SSE2.
Similarly, I've removed the call to Init_neon() when NEON is available globally... it's a no-op.
Renaming namespace portable to something clearer is TBD.

This lets us test changes to BUILD.public.
This is not yet automated in any way. My hope is to trigger it quietly via the presubmit for any CL that adds or removes a file, or changes BUILD.public.

Currently, SkPaintFilterCanvas does not provide any help in cloning
target canvas state. While that could be handled in subclasses, it is
easy to miss (see linked bug).
This CL adds a new constructor variant which ensures that the initial
matrix and clip bounds are inherited from the target canvas.

Many of these were excluded from the build for bots that no longer exist.

Add more swizzling functions for swizzling to 565. Much of this
code was revived from crrev.com/1055743003 (for BMP). Also added
swizzling functions for WBMP.
Consolidate the static function conversion_possible.
In SkCodec::getPixels, check that the alphatype corresponds to the
colorType. This prevents requesting 565 + non-opaque.
In SkIcoCodec, report that the image is unpremul (instead of
whatever the largest embedded codec thinks), but modify the
requested info to have the alpha type expected/required by the
embedded codec.
Add tests for decoding to 565.
