Tag bitmap as sRGB, and adjust gain/bias in color-managed configs to
produce results that are less blown out.
Also added a colorized version of the GM, to validate that gamut
conversion is working.

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.

Reason for revert:
Introduced memory leak; pixel changes in Chrome.

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases. We'll have to manually clean up the rest
over time unless I level up in regexes.
for f in (find . -type f); perl -p -i -e 's/virtual (.*)SK_OVERRIDE/\1SK_OVERRIDE/g' $f; end

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can be removed in the future when the Font Manager can be superceded.

- Rename TileGrid -> Quilt to avoid the name overload.
- Tag all failing GMs with kSkipTiled_Flag.
You may be wondering, do any GMs pass? Yes, some do! And that trends towards all of them as we increase --quiltTile.
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.)

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.

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.

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".
