179d88522c Only test SVG DM sources against direct raster/gpu sinks.
There isn't much value in testing against indirect or vector sinks.

8fd23a86d0 Remove SkPreprocessorSeq.h and SkTypedEnum.h.
These were added to allow the use of typed enums before typed enums were
available on all platforms. Now that typed enums are available, just use
them directly.

3287588a46 SkPDF: SkPDFFont class changes
SkPDFFont:
  * inline some one-line methdods.
      - SkPDFFont::typeface()
      - SkPDFFont::fontInfo()
      - SkPDFFont::firstGlyphID()
      - SkPDFFont::lastGlyphID()
      - SkPDFFont::getFontDescriptor()
  * de-virtualize some methods:
      - SkPDFFont::getType()
      - SkPDFFont::multiByteGlyphs()
  * Constructor takes more arguments:
    fontType, multiByteGlyphs
  * re-order fields (pointers before shorts)
  * use sk_sp<T> more, T* less

SkAdvancedTypefaceMetrics:
  * SkAdvancedTypefaceMetrics::fFont now a uint8_t
  * other enumes are sized.
  * SkAdvancedTypefaceMetrics::fStyle now big enough.
  * remove use of SkTBitOr, replaced with fancy templates

No public API changes.

883c8efae7 SkLiteDL: remove freelisting, add reset() and SKLITEDL_PAGE knob.
We think Android can cache these better than a global freelist allows.
This removes the freelisting but adds reset() to allow reuse.

I took the opportunity to abstract 4096 as a define SKLITEDL_PAGE.

8079ba688c GN: add extra_cflags et al.
Adding flags to the end of cc or cxx is pretty useful, but these always end up
on the command line before the GN generated flags, thus setting defaults that
GN will override.

For full flexibility we want to be able to add flags after the flags GN has
added, so that custom flags can override _it_.

I've updated the Fast bots with an example here: if we said cc="clang -O3 ...",
that '-O3' would be overriden later by the default Release-mode '-Os'.  By
putting it in extra_cflags, we get the last word: our '-O3' overrides the
default '-Os'.

Another good use case is a hypothetical Actually-Shippable-Release mode.  Our
Release mode bundles in tons of debug symbols via '-g'.  libskia.a is about 10x
larger than it needs to be when built that way, but it helps us debug the bot
failures immensely.  To build a libskia.{a,so} that you'd really ship, you can
now set extra_cflags="-g0" to override '-g'.  You could set '-march' flags there
too, '-fomit-frame-pointer', etc.

There are lots of flags that won't matter where they end up in the command line.
To keep everything simple I've put them in extra_cflags with the rest.  This means
the only time we change 'cc' or 'cxx' in our recipes is to prefix 'ccache'.

2f4114a246 32-bit fast hash, tidy up murmur3 a bit
Nothing too surprising in the new 32-bit x86 hash.  It's about half speed of the 64-bit variant, just as you'd expect.

Using unaligned_load like the others makes the may_alias parts of murmur3 moot.  I've updated some of the terms in the murmur hash to read consistently with the others.

The existing hashes are the same speed and produce the same hashes.  In case this is not obvious, all three hash functions produce different hashes.

af68fa11ed Improvements for circluar blurs in GPU backend.
Use half plane approximation for small blur of a large circle. This reduces

circle radii.

d707f2d1cf Moved "drawShadowedPicture" call outside of if cases in onDrawContent.
Bug description:
If you updated the view without changing frames (such as moving around the
cursor with 'z' (pixel zoom) on) the window would turn gray.

This was because I left the drawShadowedPicture call inside of the "if-updated"
case inside of SampleShadowing's onDrawContent handler.

If nothing changed and onDrawContent is called, we still need to update the
given canvas's fLights (there is no guarantee of whether the canvas (or its
fLights) has been updated or not), and then draw the shadowed picture.

36c38cbb29 Fix WIC encoder to support kJPEG_Type
(1) Add support for kJPEG to WIC
(2) Add encoding test.
(3) Turn on WIC jpeg encoder on Windows and CG jpeg

A follow-up may make Skia's encoders the default on all
platforms.  But, in order to do that, I think we need
to write better encoding unit tests for CG and WIC.

200877eeca Optimize color xforms when src and dst are matching
Useful when:
(1) Client does not realize src and dst match (calls color
    xform anyway).
(2) Client wants half floats, src and dst have matching
    gamuts
(3) Client wants premul (done correctly in linear space),
    src and dst have matching gamuts.

ced26a3d6b add parallel public API for recording SkLiteDL.
The API is restricted to pretty much just what Derek calls,
but it's enough that we can switch testing over to use it.

d5d3287fe2 Skip CompressCheckerboard unit test on N6.
This is at least one of the failures making the bot red.
The particular signal indicates it's probably an alignment problem.

de44222033 Webp has_alpha is a hint only
The has_alpha bit on webps is a hint only.  We are correct to always
assume that the image may have alpha.
