The SkStrikeServer maintains a map of SkGlyphCacheState to track the
cache for a strike on the client. This entry is evicted only on a
failure to lock, which means that the map can potentially grow unbounded
if entries are not reused after eviction.
Make sure we check that they are deleted after some limit.

Easily supports mapping ctypes to sksl types with templates that
specify how to send data to the GPU and how to track state changes.
The template logic and type mappings are defined in
SkSLCPPUniformCTypes.* while SkSLCPPCodeGenerator is updated to
utilize it.
It also updates the supported ctypes to properly generate code for
SkPoint, SkIPoint, SkIRect, and GrColor4f. The code generated for
'in uniforms' now also correctly supports conditional uniforms.

This expands sksl's capabilities with .fp files. Previously, it was possible to declare "in fragmentProcessor foo" and emit it automatically when "process(foo);" was called. This adds a variant of process that takes a second argument, which must be a half4 expression. This argument specifies the value, or dynamic expression calculated earlier in the parent shader, to use as sk_InColor by the child.
The CL is longer than anticipated because of properly handling dependencies between previous sksl statements and the input to the child. The original writeEmitCode() collected all extra emission code (the calls to build->emitChild) and put them before any call to codeAppendf. This makes it impossible to use a parent's variable, or the output of another child, as the input for process.
To solve this, there is now a flushEmittedCode() function that takes over the logic of outputting the extra emission code and the necessary codeAppendf calls. When invoked, it (by default) only appends completed sksl statements, and places any current expression back at the beginning of the output stream. It now updates fFormatArgs and fExtraEmitCodeCode as it consumes their contents. This allows writeFunctionCall() for a call to "process" to flush all previous statements before it adds its emit child code.

PathOps added a cheat some time ago to reduce
fuzzer bugs by scaling down very large paths,
with the hope that it would make the math more
sane.
This had the side-effect of causing small edges
to disappear altogether if the bounds is large
enough.
Removing the scaling causes a single regression to
one fuzz-generated bug. That path succeeeded with
scale by eliminating the troublesome tiny contour.
Eliminating the scale may fix the CCPR-related bug
discovered by Flutter, or at least uncover the next
bug.
I would expect more fuzzer bugs to appear with
this change; paths with large and small values will
no longer have the small values removed.

Pathops determines which edges are kept and discarded
by sorting intersections counterclockwise. An edge
may be unsortable if it is too close to a neighbor to
clearly be on its left or right.
If a pair of lines is unsortable, they are probably
nearly coincident, but just far enough apart to escape
the coincident test.
The current code correctly marks the lines as unsortable,
but returned a guess at the sorting order anyway. Instead,
preserve the unsorted-ness (unsorted mess?) and let
the decision of what to keep defer til later.
This triggered a couple of asserts that needed rewriting
or disabling, but fixes the bug in question and does not
regress the extended tests in debug or release.
Also, fix a debugging routine that bit-rotted.

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

Add a SK_LEGACY_SKCODEC_NONE_ENUM #define'able to ease transition.
Also rename another internal "kNone" enum in SkWebpCodec.cpp.
The "kNone" name is overloaded:
- include/core/SkImageGenerator.h defines its own kNone.
- include/encode/SkPngEncoder.h defines its own kNone.
- include/private/GrTypesPriv.h defines multiple kNone's.

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
