This eliminates some variability on various axes: different PNG encoders, different libpng versions, different formats (RGB, indexed), different unpremultiplication, different sRGB tags.

We don't want to test small images on Gold because they are
not interested to look at. Instead, I wrote a unit test to
verify that scaling small images does not cause crashes.

IDWriteFamily::GetFamilyNames appears to be 'helpful' and removes
parts of family names that look like style names. Since the iterator
is supposed to return the actual names and not just the name the
platform thinks the name is (as getFamilyName does), try returning
the raw names when possible.

- SSE2 files are unfortunately now mixed-case, _SSE2 or _sse2.
- Adds lists for SSSE3 and SSE4 files.
- Remove SkDocument_PDF_None.cpp
- Remove a few more references to animator.
- Exclude private headers from HDRS.
- Formatting and notes.

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.
