7147ee1b80 Expat target exports includes instead of FreeType.
Currently when building for Android framework the freetype target
exports the expat include directory, but the freetype target neither
uses nor logically provides this information. Instead, the expat target
itself should do this.

e3031b607c Update ANGLE to latest as of August 25, 2016
With this version, it's now exposing GL_EXT_color_buffer_half_float, but
it's (incorrectly) using GL_HALF_FLOAT rather than GL_HALF_FLOAT_OES.
In addition, release builds were crashing in EGLImageTest due to an
apparent disagreement about calling convention on function-pointer to
exported symbol. There is a proper typedef for that in one of their
headers, but I can't seem to include it without creating more problems,
so I just fixed the decoration on our local typedef.

With those changes, all tests pass, and (on my Windows machine), all
GMs and SKPs produce identical results vs. master in angle and angle-gl.

650e20d705 SkPDF: Stop #include PREPROCESSOR_DEFINE pattern
No more:
   #include SK_SFNTLY_SUBSETTER
   #include ZLIB_INCLUDE

Also, rename SK_SFNTLY_SUBSETTER to SK_PDF_USE_SFNTLY
to follow my pattern of prefixing SkPDF-specific defines
with 'SK_PDF_'.

The ZLIB_INCLUDE define is no longer is used by anyone.

TODO: rename Sfntly to something pronounceable.

e37aa89c5c gyp/sfntly: set SK_SFNTLY_SUBSETTER uniformly
When Skia is built into the Android framework,
SK_SFNTLY_SUBSETTER="sample/chromium/font_subsetter.h".
This sets the same value for Skia's test framework

I will eventually move away from the
   #include PREPROCESSOR_DEFINE
trick, which does not work everywhere.

No public API changes.

78559a78f9 Use ARMv8 CRC32 instructions for SkOpts::hash().
For large inputs, this runs ~11x faster than Murmur3.
My bench drops from 1µs to 88ns.

Like x86-64, this runs fastest if we work in 24 byte chunks.  16 byte chunks
run at about 0.75x this speed, 8 byte chunks at about 0.4x (which would still
be about 5x faster than Murmur3).

This'll require plumbing support for opts_crc32 into Chrome first before it can roll.

perf.skia.org charts we want to watch: https://perf.skia.org/#5490

28341fad84 Implement difference clip rects with window rectangles
Plumbs the pipeline for window rectangles and uses them for a very
basic implementation of difference clip rects. This puts a common
Blink pattern on fast path, but we will still eventually need to make
more comprehensive use of window rectangles during clipping.

36931c2b47 Add test for platform encoders, turn off platform encoders by default
Clients that like WIC and CG can still use them.  And we can be
confident about that, since we now test WIC and CG.

Let Skia always use our own encoders by default, so we can do cool,
custom things on all platforms.

3d96cb8db7 Default GR_GL_FUNCTION_TYPE to __stdcall on Windows.
Why is this configurable if we can't work without it?

Just to confirm, this is a Windows constraint, not an MSVC constraint, right?
Clang on Windows also needs __stdcall?

8eccc308c8 SkPDF: SkPDFFont organization changes.
SkPDFFont:
  - SkPDFType1Font::populate() encode advances correctly.
  - break out logically independent code into new files:
    * SkPDFConvertType1FontStream
    * SkPDFMakeToUnicodeCmap
    SkPDFFont.cpp is now 380 lines smaller.
    Expose `SkPDFAppendCmapSections()` for testing.

SkPDFFontImpl.h
  - Fold into SkPDFFont.

SkPDFConvertType1FontStream:
  - Now assume given a SkStreamAsset

SkPDFFont:
  - AdvanceMetric now hidden in a anonymous namespace.

No public API changes.

0446a3c8e2 Add initial CurveMeasure code
- This code is entirely private and is not being used by anything.

- In a future CL we will write a class that uses CurveMeasure to compute dash points. In order to determine whether CurveMeasure or PathMeasure should be faster, we need the dash info (the sum of the on/off intervals and how many there are)

4e97607d9a Use sse4.2 CRC32 instructions to hash when available.
About 9x faster than Murmur3 for long inputs.

Most of this is a mechanical change from SkChecksum::Murmur3(...) to SkOpts::hash(...).

f95388da1a Remove SK_SUPPORT_LEGACY_DATA_FACTORIES.
The code protected by this flag is no longer used. Remove the flag and
code. This also removes SK_SUPPORT_LEGACY_TYPEFACE_PTR from Android, as
it is no longer needed.

Only removes already guarded API.

9c5052f16b SkLite*
SkLiteRecorder, a new SkCanvas, fills out SkLiteDL, a new SkDrawable.

This SkDrawable is a display list similar to SkRecord and SkBigPicture / SkRecordedDrawable, but with a few new design points inspired by Android and slimming paint:

  1) SkLiteDL is structured as one big contiguous array rather than the two layer structure of SkRecord.  This trades away flexibility and large-op-count performance for better data locality for small to medium size pictures.

  2) We keep a global freelist of SkLiteDLs, both reusing the SkLiteDL struct itself and its contiguous byte array.  This keeps the expected number of mallocs per display list allocation <1 (really, ~0) for cyclical use cases.

These two together mean recording is faster.  Measuring against the code we use at head, SkLiteRecorder trends about ~3x faster across various size pictures, matching speed at 0 draws and beating the special-case 1-draw pictures we have today.  (I.e. we won't need those special case implementations anymore, because they're slower than this new generic code.)  This new strategy records 10 drawRects() in about the same time the old strategy took for 2.

This strategy stays the winner until at least 500 drawRect()s on my laptop, where I stopped checking.

A simpler alternative to freelisting is also possible (but not implemented here), where we allow the client to manually reset() an SkLiteDL for reuse when its refcnt is 1.  That's essentially what we're doing with the freelist, except tracking what's available for reuse globally instead of making the client do it.

This code is not fully capable yet, but most of the key design points are there.  The internal structure of SkLiteDL is the area I expect to be most volatile (anything involving Op), but its interface and the whole of SkLiteRecorder ought to be just about done.

You can run nanobench --match picture_overhead as a demo.  Everything it exercises is fully fleshed out, so what it tests is an apples-to-apples comparison as far as recording costs go.  I have not yet compared playback performance.

It should be simple to wrap this into an SkPicture subclass if we want.

I won't start proposing we replace anything old with anything new quite yet until I have more ducks in a row, but this does look pretty promising (similar to the SkRecord over old SkPicture change a couple years ago) and I'd like to land, experiment, iterate, especially with an eye toward Android.
