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.

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.

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.

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.

Add an FP that provides the two-point conical gradient effect. The
majority of the new FP's shader code is a straight forward port from
SkTwoPointConicalGradient_gpu.cpp. This FP is bulkier because of the
extensive calculations that go on in its overridden Make function.
To support 2-pt conical gradient's behavior of writing transparent
black in invalid areas of the conical interpolation, the contract of
gradient layout FPs has been updated to provide a flag in the y
component as to whether or not the fragment should be rejected.
A separate channel was used since negative values and large values are
perfectly reasonable for the untiled gradient layout to return (before
the value is then constrained into [0, 1]). It also seemed better to
avoid returning a problematic value like infinity or NaN.

Redefines how gradients will be written in the GPU back-end:
They are split into three fragment processor components: master, layout, and colorizer.
The layout FP is responsible for converting the fragment position into an interpolant value, t.
Each high-level gradient--such as linear, radial, etc.--are implemented solely in a layout FP.
The colorizer FP is responsible for converting t into a color.
The master FP invokes the layout, clamps t into the proper domain, and then invokes the colorizer.
GrGradientShader provides factory functions to create FP graphs from SkGradientShader instances.
This pattern is documented in gpu/gradients/README.md.
Goals for current CL
====================
Outline the FP components by providing .fp implementations for the simplest gradients.
Defines a two-color single interval colorizer and a linear gradient layout, and the master effect.
A MakeLinear() factory function is provided that can convert SkGradientShaders that fit these constraints.
SkLinearGradient first attempts to use the new system, falling back to the original GrGradientEffect.
Future CLs
==========
To keep the CL reviews manageable, additional dependent CLs will be added that gradually replace past functionality.
A CL for each layout will be defined.
CLs for the different analytic colorizer cases and the textured gradient case will be defined.
Once the new system supports all current layouts and colorizer capabilities, all old GPU gradient code will be removed.
After this clean-up, analytic colorization can hopefully be expanded to reduce the usage of textured gradients.

People using is_official_build don't really want to see warnings.
They're for devs, not users.
The somewhat odd update to gn/BUILDCONFIG.gn keeps command
line flag precedence (later == more important) unchanged.

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.

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

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
TBR=reed@google.com
No public API changes. Only private/public members of SkCodec.h are
modified.
