573ce20f42 clang/win: Let SK_TRACEHR not produce -Wunused-value warnings in release builds.
Fixes warnings like:

                      ^~~~~~~~~~~~~~~~~~~~~~~~~
..\..\third_party\skia\include\utils\win\SkHRESULT.h(26,20) :  note: expanded from macro 'HR_GENERAL'
        SK_TRACEHR(_hr, _msg);\
                   ^~~
..\..\third_party\skia\include\utils\win\SkHRESULT.h(20,31) :  note: expanded from macro 'SK_TRACEHR'
                              ^~~

0745653a67 SkAlphaThresholdFilter.h allow flattening
Motivation:  allows this:

    #include "SkAlphaThresholdFilter.h"
    void init() {
      SkAlphaThresholdFilter::InitializeFlattenables();
    }

a544eda5dd Matrix convolution bounds fix; affectsTransparentBlack fixes.
Because the convolution kernel is (currently) applied in device space,
there's no way to know which object-space pixels will be touched. So
return false from canComputeFastBounds().

The results from the matrixconvolution GM were actually wrong, since
they were showing edge differences on the clip boundaries, where they
should really only show on crop boundaries. I added a crop to the GM
to keep the results the same (which are useful to test the different
convolution tile modes).

While I was at it, SkImageFilter::affectsTransparentBlack() was
inapplicable on most things except color filters, and its use on
leaf nodes was confusing. So I removed it, and made
SkImageFilter::canComputeFastBounds() virtual instead.

cb0d5c940a Add currScanline() getter to SkCodec API
This is more correct than using nextScanline() for the
SkGifCodec scanline decoder (since we will get a strange
result in the interlaced case) and is necessary if we want
to add scanline decoding to SkIcoCodec.

This does not actually fix bugs or change behavior.

The appropriate way to get the default system font is to pass |nullptr| as the

cf98fa9311 Add SkPngChunkReader.
This class allows a client of SkCodec to read chunks in the data
stream that are not recognized by libpng. This is used by Android
to specify ninepatch data.

Taken from SkImageDecoder::Peeker. Modify the name of the class
and its method to be more specific to their use. Make
SkImageDecoder::Peeker a subclass of the new class, to help stage
the change in Android.

Add a test to verify that it works.

3389e00136 Add SkPngChunkReader.
This class allows a client of SkCodec to read chunks in the data
stream that are not recognized by libpng. This is used by Android
to specify ninepatch data.

Taken from SkImageDecoder::Peeker. Modify the name of the class
and its method to be more specific to their use. Make
SkImageDecoder::Peeker a subclass of the new class, to help stage
the change in Android.

Add a test to verify that it works.

e47f1a7c74 Fix UB in SkDivBits
This used to:
  DIVBITS_ITER was shifting bits up into the sign bit, which is a no-no.
  This turns numer into a uint32_t to make those defined, and adds a few notes.

  x >= 0 is always true for unsigned x, so we needed a few small logic refactors.

Instead it now:
  Only call SkDivBits if the old behavior is required.
  Usually, just do the divide with /.
