Flutter barely needs the float stages, and

0a0304c426 Add experimental API to draw a set of SkImages in one SkCanvas call.
The client provides a src and dst rect for each image as well as
a bitfield that indicates whether each edge of the image should be
antialiased. This per-edge AA is useful for tiled compositors.

Rather than take a full SkPaint this API only takes an alpha, a filter
quality (which is pinned to kLow), and a blend mode. This is a likely
point of future evolution.

Currently the API is only fully implemented for kSrcOver on the GPU
backend. With other blend modes or on other backends AA will be ignored
for images that do not have all four edge AA flags set.

1421120316 disable DAA and AAA in flutter
If we're looking to cut out unnecessary code in Flutter,
SkScan_AAA always jumps out to me as a bunch of code that
is not logically required for GPU rendering.

Looking at a treemap[1], SkScan_AAA is the biggest chunk of
code under src/core.  I don't see DAA... maybe it's small,
or somehow already trimmed?  Anyway, I cut it out too.

generally uses the same number of bits, but these are usually different
types (signed vs. unsigned). Detect the actual type in use where needed.

72535fb55a Reland "Reland "Implement an explicit binary search-based analytic gradient colorizer""
This is a reland of f065907ccc

3rd time's the charm:

The new analytic gradient shader was sporadically triggering violations of the coverage as alpha
compatibility optimization. Unfortunately, even when using the same device and random seed for the
test, the bots did not always reproduce the error. However, we identified the likely cause of the
violation.

The test requires that all output channels are less than the input alpha, which it uses to validate
whether or not the shader is modulating its values by the input alpha. This test does not pass if
the RGB values are greater than 1. The original version of the analytic gradient shader used half4s
for its scale and bias values. Given the threshold limit for hardstops of 0.00024 (SkNearlyZero),
a very small interval that is not treated as a hardstop can create a scale or bias of over 4000.
This moves into the very imprecise region of 16-bit floats, making it plausible that the gradient
outputs colors greater than 1, due to rounding. The kicker is that the random test generation for
stop locations does not use a uniform distribution, but is instead biased towards the remaining
interval, which increases the likelihood of generating a small interval that is not treated as a
hard stop. We are keeping this behavior since ill-conditioned gradients are useful in testing.

Outsetting in perspective case outsets the original homogeneous quad
points rather than the homogenized 2d points in order to avoid seaming
issues along shared edges.

Currently there is no way to trigger this from the public API and it
is tested by directly accessing GrRenderTargetContext from the added gm.

cbcff385c1 Have pathkit use libpathkit.a for faster builds
Of note, it is very important for the -DSK_RELEASE/-DSK_DEBUG
to match between libskia.a and the WASM bindings, otherwise
things like SKDEBUGCODE are sometimes compiled in and sometimes
not, which can cause headaches like sizeof() mismatching between
.cpp files and .h files.

  -- adds internal place holder for YUVA promise images (only returns Y channel)

https://skia-review.googlesource.com/c/skia/+/156140 (Add SkImage_Base API to access planar data)

66c505f6e8 expand imageinfo in C api, start on colorspace
After sk_imageinfo was initially created, we have added a colorspace to it,
and that object is a smart-pointer. In response to that, this CL upgrades
imageinfo to an "object" (like paint), so we can manage the ref-counting of
its colorspace, and to allow for future changes/expansion (like paint).

656cefe65d Add initial support for generating tagged PDFs.
Adds an interface for the document creator to pass in a tree
of tags indicating the structure of the document, each with a type
(from a predetermined enum of possible types) and a node ID.
It also adds a setNodeId function to SkCanvas so that page content
can be associated with a particular tag. If both the tag tree and
marked content are present, Skia can now output a properly tagged
PDF.

An example program is included. When used properly, the PDF generated
by this patch is valid and the tags are parsed properly by Adobe
Acrobat. It handles many corner cases like content that spans more
than one page, or tags that don't correspond to any marked content, or
marked content that doesn't correspond to any tags.

However, it doesn't implement all of the features of PDF accessibility
yet, there are some additional attributes that can be associated with
some tags that need to be supported, too, in order to properly tag
things like figures and tables.

cfe1264d74 GrTessellator: two fixes for boundary simplification artifacts.
The "pointy vertex" test was only considering the distance from the
next (outgoing) edge to the previous point. It must also consider the
distance from the previous (incoming) edge to the next point. If
either are less than a quarter pixel, the vertex is considered pointy
and should be removed. (884166)

Also (887103), when an interior region was completely removed due to
boundary simplification, it would leave a degenerate edge consisting
of the same vertex. So avoid introducing a join edge when prev == next.

Bug: 884166, 887103

dcc85fc610 Implement an explicit binary search-based analytic gradient colorizer
Provides a reasonably flexible fragment processor that defines another
colorizer implementation for gradients. It can support up to 8
interpolation intervals (which is 16 colors if every stop is a hard stop
or 9 colors if every stop is a smooth transition). It
supports mixtures of hard and smooth stops. It is conditionally compiled
into versions specific to the interval count (so it can produce up to
8 shader variants).

The GrGradientShader controller does not remove the single and dual
interval colorizers, which are useful specializations of this explicit
binary search colorizer. Similarly, since it can only handle up to 8
intervals, the texture colorizer is still used as a fallback.

Currently it does not employ capabilities detection to determine if the
hardware can support the number of required uniforms, which can become
substantial for the larger gradient configurations.
