bd1466cd4e Add a new gm for large kernel matrix convolution
As a precursor to 263495, we need test coverage for this.

According to Skia Gold, the current matrix convolution implementation test is showing very different results on CPU & GPU. On the CPU, the last test case turns blue! See closest negative here: https://gold.skia.org/search?fdiffmax=-1&fref=false&frgbamax=255&frgbamin=0&head=true&include=false&limit=50&master=false&match=name&metric=combined&neg=true&new_clstore=true&offset=0&pos=true&query=cpu_or_gpu%3DGPU%26name%3Dmatrixconvolution_color%26source_type%3Dgm&sort=desc&unt=true

7fde8e1728 IWYU for gms.
This almost gets gms to be iwyu clean. The last bit is around gm.cpp
and the tracing framework and its use of atomic. Will also need a way
of keeping things from regressing, which is difficult due to needing to
do this outside-in.

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

gm.h includes sk_tool_utils.h but does not use it.

sk_tool_utils.h also provided SkRandom and SkTDArray,
so a couple GMs add those headers too.

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.

992c7b03ef Add standard fonts to all GMs.
Allow GM results to be compared across machines and platforms by
standardizing the fonts used by all tests.

This adds runtime flags to DM to use either the system font context (the
default), the fonts in the resources directory ( --resourceFonts ) or a set
of canonical paths generated from the fonts ( --portableFonts ).

This CL should leave the current DM results unchanged by default.

If the portable font data or resource font is missing when DM is run, it
falls back to using the system font context.

The create_test_font tool generates the paths and metrics read by DM
with the --portableFonts flag set, and generates the font substitution
tables read by DM with the --resourceFonts flag set.

If DM is run in SkDebug mode with the --reportUsedChars flag set, it
generates the corresponding data compiled into the create_test_font tool.

All GM tests set their typeface information by calling either

  sk_tool_utils::set_portable_typeface or
  sk_tool_utils::portable_typeface .

(The former takes the paint, the latter returns a SkTypeface.) These calls
can be removed in the future when the Font Manager can be superceded.

Two GMs only fail in --quilt mode in 565.  Otherwise all GMs which fail are skipped, and those which don't fail aren't. (The 8888 variants of those two GMs are skipped even though they pass.)

ff06af20fd Changing imageFilter GM tests to use drawBitmap instead of drawSprite
The motivation is be able to test the filters with scaled SkPicture playback in isolation from the issues that surround usage of drawSprite

3bc16c8bc1 Implement GPU path for matrix convolution. Note that when not convolving alpha,
the premultiplying is done less efficiently than in the raster path:  it's
done on each texture access, rather than as a pre-processing pass.   This was
so I could do the filter as a single custom stage; will try the optimization
separately.

This implementation gives a ~30X speedup on the GPU results for the
matrixconvolution bench (~10X due to the GPU, and ~3X due to texture
uploads/readback removal).

Note:  this changes the matrixconvolution for the software path as well, so
it will likely break the bots until that test is rebaselined.

8640d5024d This patch adds support for optional processing of the alpha channel in
the matrix convolution filter.  Test cases are added to the GM and the
bench.

NOTE:  This will require rebaselining the matrixconvolution GM, so it will 
likely turn the bots red until that is done.

5faa2dc266 Implements a matrix convolution filter (raster path only). The filtering loop
is templated on the tiling mode for speed:  interior pixels are unconditionally
fetched; border pixels apply the appropriate tiling mode before fetching.  It
handles target, bias, divisor (as gain), and edge modes (named to be more
skia-like).  It does not handle the "preserveAlpha" semantics of
feConvolveMatrix, nor "kernelUnitLength".
