Reland "Reland "Implement an explicit binary search-based analytic gradient colorizer""
This is a reland of f065907ccc0ae5e9258443b5a1bbabeef181e965
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.

GrTessellator: improved straight skeleton implementation.
This patch improves the straight skeleton implementation used by
GrTessellator to collapse overlap regions in the alpha gradient border.
The resulting quality improvement can be seen in the
"thinconcavepaths" GM, for example, where the coverage values of
the "thin right angle", "thin rect and triangle" and "skinny snake"
are now lower and match the raster backend more closely. It also improves
correctness, such as on the linked Chromium bugs below.
Previously, the straight skeleton was performed using the same Vertex
and Edge classes used for tessellation, but this led to fragility in
maintaining the connectivity and ordering required by those classes.
Instead, that functionality has been moved to new SSEdge and SSVertex
classes. Their construction results in alternating SSVertex and
SSEdges around the boundary of the each overlap region, shrunk by one
SSEdge as the boundary collapses.
Applying events may now also create further events (chained events),
as intersections between newly-adjacent bisectors change the structure
of the skeleton. This is always calculated from the bisectors of
original boundary, not the shrunk boundary of the straight skeleton,
which is why each SSEdge points at its originating Edge. If the edges
are parallel or near-parallel, the bisector may be infinite. This is
handled by a new flavour of create_event(), which does a Line/Line
intersection (rather than an Edge/Edge intersection) to find the
intersection between the infinite bisector and an adjacent bisector.
Several ancillary bugs were fixed: the priority queue used to represent
edge events was sorting the inner edges incorrectly. These need to be
sorted in descending not ascending order of coverage. Its implementation
was moved from Skia's TDPQueue to std::priority_queue(), which is more
flexible in specifying a comparator.
check_for_intersection()'s partner synthesis code was moved into a new
function, compute_bisector(), also used by the chained skeleton events
code.
Degenerate edges are now removed during the simplify_boundary() pass.
They were previously detected but ignored, causing incorrect inner and
outer tangents to be computed in stroke_boundary().
An fSynthetic flag was added to Vertex, in order to detect vertices
which cannot be moved by an edge collapse event (e.g., intersections
with non-boundary edges, merged vertices, straight skeleton vertices).
More raw implementation notes:
Connect straight skeleton vertices as we find them, so we don't
have to use partnering (ss_connect()).
Only disconnect edges which are still alive after event application.
Add a check for near-parallel lines in compute_bisector().
Don't use edge type to determine direction to offset for bisectors.
The winding should already include this information.
Move Event ownership to SSEdge.
If we're down to the last two edges in a skeleton, don't check for events.
Add concave_arc_and_circle GM.
Add a collapsepaths GM.

Update how sample(matrix) calls are invoked in SkSL
This removes the kMixed type of SkSL::SampleMatrix. All analysis of FP
sampling due to parent-child relationships is tracked in flags on
GrFragmentProcessor now.
The sample strategy is tracked as follows:
- An FP marks itself as using the local coordinate builtin directly (automatically done for .fp code based on reference to sk_TransformedCoords2D[0]).
- This state propagates up the parent towards the root, marking FPs as using coordinates indirectly. We stop the propagation when we hit a parent FP that explicitly samples the child because it becomes the source of the child's coordinates.
- If that parent references its local coordinates directly, that kicks off its own upwards propagation.
- Being sampled explicitly propagates down to all children, and effectively disables vertex-shader evaluation of transforms.
- A variable matrix automatically marks this flag as well, since it's essentially a shortcut to (matrix expression) * coords.
- The matrix type also propagates down, but right now that's only for whether or not there's perspective.
- This doesn't affect FS coord evaluation since each FP applies its action independently.
- But for VS-promoted transforms, the child's varying may inherit perspective (or other more general matrix types) from the parent and switch from a float2 to a float3.
- A SampleMatrix no longer tracks a base or owner, GrFragmentProcessor exposes its parent FP. An FP's sample matrix is always owned by its immediate parent.
- This means that you can have a hierarchy from root to leaf like: [uniform, none, none, uses local coords], and that leaf will have a SampleMatrix of kNone type. However, because of parent tracking, the coordinate generation can walk up to the root and detect the proper transform expression it needs to produce, and automatically de-duplicate across children.
Currently, all FP's that are explicitly sampled have a signature of (color, float2 coord). FP's that don't use local coords, or whose coords are promoted to a varying have a signature of (color).
- In this case, the shader builder either updates args.fLocalCoords to point to the varying directly, or adds a float2 local to the function body that includes the perspective divide.
GrFragmentProcessor automatically pretends it has an identity coord transform if the FP is marked as referencing the local coord builtin. This allows these FPs to still be processed as part of GrGLSLGeometryProcessor::collectTransforms, but removes the need for FP implementations to declare an identity GrCoordTransform.
- To test this theory, GrTextureEffect and GrSkSLFP no longer have coord transforms explicitly.
- Later CLs can trivially remove them from a lot of the other effects.
- The coord generation should not change because it detects in both cases that the coord transform matrices were identity.
GrGLSLGeometryProcessor's collectTransforms and emitTransformCode has been completely overhauled to recurse up an FP's parent pointers and collect the expressions that affect the result. It de-duplicates expressions between siblings, and is able to produce a single varying for the base local coord (either when there are no intervening transforms, or the root FP needs an explicit coordinate to start off with).
This also adds the fp_sample_chaining GM from Brian, with a few more configurations to fill out the cells.

Adjust GPU YUV -> RGB (JPG) conversion
All of the published coefficients assume math is being done on bytes, and
that 128 is the encoding of 0 (in the biased Cb and Cr values). When
sampling an A8 texture, though, GPUs typically decode as byte/255. Thus,
128 ends up slightly larger than 0.5. To fix this, just adjust the bias
terms to be scaled by 128/255, rather than 0.5.
I also changed some of the other coefficients to be higher precision,
based on the values in ITU-T T.871.
This originally surfaced as a Chromium bug where an all-black JPG decoded
to (1/255, 0, 1/255) on GPU. I've added a GM that encodes a color cube to
JPG, then draws from the encoded data. GPU and CPU (libjpeg) still
disagree in many cases, but the newer version performs much better
(diffing gl and 8888 configs):
Previously: 95.2% of pixels differ, max diff of 2, avg diff of 1
Now : 65.4% of pixels differ, max diff of 1, avg diff of 0
