Implements strokes by linearizing the curve into fine triangle strips
and interpolating a coverage ramp for edge AA. Each triangle in the
strip emits either positive or negative coverage, depending on its
winding direction. Joins and caps are drawn with the existing CCPR
shaders for triangles and conics.
Conic strokes and non-rigid-body transforms are not yet supported.

The texture strip atlas code path has been disabled without performance
regressions since 8/3/18, so this deletes it completely from the code
base since it is complex and difficult to manage.
GrTextureStripAtlas, GrDynamicTextureStripAtlas, and
GrDDLTextureStripAtlas completely deleted, everything else is cleaning

Create an skcms_Profile instead of an SkColorSpace when creating an
SkCodec. Eventually we'll move the SkImageInfo (and its SkColorSpace)
entirely to clients (e.g. SkAndroidCodec, SkCodecImageGenerator), but
for now, create it with SkEncodedInfo::makeImageInfo.
Create new SkEncodedInfo::Colors for the special PNG cases that we
want to map to specific SkColorTypes.
SkEncodedInfo:
- Add ICCProfile, which owns an skcms_ICCProfile
- FIXME: maybe we should have a single instance for
SRGB like SkColorSpace?
- Add kXAlpha_Color, for kAlpha_8. Since I'm not longer creating
an SkImageInfo (at least in SkPngCodec), it needs a way to pass
this info to the caller.
- Add k565_Color, for the same reason. Matt originally had this in
https://codereview.chromium.org/2212563003/#ps120001, but didn't
land that version. I like it though. Mike didn't like the bits
per component for 565, but it seems like a sensible hack, much
like the existing one for kAlpha_8
- Add width and height. These were removed for redundancy with
SkImageInfo, but it makes sense to have them here without it.
BUILD.gn:
- Build the new SkEncodedInfo.cpp
SkCodec:
- Remove the constructor with an SkImageInfo. Edit the other one
to drop width and height (now in SkEncodedInfo) and take a RHS
reference to SkEncodedInfo
- Create the SkImageInfo from fEncodedInfo (for now)
- Consolidate choosing skcms_AlphaFormat for Transform here
- Call conversionSupported from initializeColorXform, with a new
parameter for whether there is a color Xform, allowing SkJpegCodec
and SkHeifCodec to override that method instead of having another
method.
SkBmpCodec (etc)
- Adapt to the changes above
- Create a new SkEncodedInfo w/o profile for the swizzler.
SkPngCodec:
- use the new SkEncodedInfo::Colors rather than a custom SkImageInfo
SkRawCodec:
- Remove SkEncodedInfo from SkDngImage, which doesn't actually need it.
This is helpful since we don't know all the info yet.
- Rewrite gAdobeRGB_toXYZD50 as an skcms_Matrix3x3
SkWebpCodec:
- Remove premul_step computation, and simplify to just rely on
the base class' handling of applying the transform.
SkSwizzler:
- Add cases for the new SkEncodedInfo::Colors

No public API changes. Only private/public members of SkCodec.h are
modified.

There's really no reason to prevent any of these conversions;
they all have somewhat reasonable behavior:
- converting between grey in different color spaces
should probably work just fine
- we'll convert color to gray using a fixed set of
luminance coefficients, but that's better than failing
- we'll invent {r,g,b} = {0,0,0} if we convert alpha
to something with color
- converting to opaque formats without thinking about
premul/unpremul is probably fine, better than just
not working at all
- a missing src color space can always be assumed to be sRGB
Updates to ReadPixelsTest:
- skip more supported test cases in test_conversion(),
each with a TODO
- conversions from non-opaque to opaque should now work
- conversion from A8 to non-A8 should sometimes now
work on GPUs, and the test needed a little bit of
a tweak to not expect A8 to carry around color somehow.
Updates to SRGBReadWritePixelsTest:
- writing untagged pixels shouldn't fail anymore;
instead, it should behave like it was tagged sRGB

This basic implementation works for simple non-intersecting paths.
It may fail if contours in paths touch, specifically when the leftmost

If this interface and implementation look promising, I will continue to

The current documentation states that SkFontMgr::matchFamilyStyle will
never return nullptr, resolving to the default system font or the empty
typeface if necessary. This isn't the behavior desired by any users,
since doing so makes it difficult for the user to check if a 'good'
match was made or not. All of the current SkFontMgr implementations can
return nullptr anyway for a number of reasons, from lack of a 'good'
match to an error.

This is a behavior change and a simplification.
When an image is incomplete or subset, we fill the remaining/all rows
with the fill color. A virtual method chose the fill color. Here were
the implementations:
- SkGifCodec:
Use transparent. This was changed previously to match Chromium.
- SkPngCodec/SkBmpStandardCodec:
Use the first color in the color table. This made sense when we had to
support kIndex_8, when we had to use an index from the color table.
Using that color for other types ensured that the image looked the same
in e.g. kN32 as kIndex_8. Removing this arbitrary choice simplifies the
code and moves the behavior toward Chromium's.
- SkCodec (default):
Use black for opaque images and transparent for images with alpha. A
theoretical advantage to this decision was that an incomplete image
would look the same in k565 and kN32. I don't think this is a good
enough reason to behave differently from Chromium.
Consolidate them all to just use 0. This results in transparent where
that is something we can specify. For 565 and Gray, this results in
black.
Only change to include headers is the removal of protected methods.

This sanitizer checks for overaligned reads and writes,
or put another way, use of underaligned pointers.
This usually happens when you cast, e.g. char* to int*
without checking that the char* is 4-byte aligned. Each
of the changes under src/ fixes something just like that.
The unusual setup for tools/xsan.blacklist is there to
force a rebuild whenever tools/xsan.blacklist changes.
I spent a good few minutes debugging rebuilds not happening
this morning, perhaps from some strange ccache interaction.
Align SkTextBlobs as void* (today they're just 4-byte) so the
SkTextBlob::RunRecords we put after them in SkTextBlobBuilder
buffers are properly aligned (for the SkTypeface* inside).
There's no obvious error in void SkRRect::computeType(),
but one bot seems to have seen some sort of issue with
SK_AT_SCOPE_EXIT(SkASSERT(this->isValid()));
I can't reproduce it locally, so I'm just going to unroll it.
