The goal of the verifier framework is to enable opt-in checks of the
images produced by individual GMs. The basis of verification will be
comparing the rendered output of a GM against a source-of-truth image,
such as one generated by the CPU backend.
In the short term this can enable coarse-grained sanity checks for a
subset of GMs to catch e.g. egregious rendering bugs. In the longer term
this can provide an SkQP-style suite of tests that can be run across
many/all GMs to provide a vote of confidence in the rendering
correctness of new devices.

Modeled on https://codepen.io/adamdupuis/pen/qLYzqB, this GM creates a
cube of rectangles with the camera at the center. It animates the FOV
since the original chrome issue was most visible when resizing the page
(which then updated the fov of the perspective css transform).
This draws correctly with the raster backend. There are two issues it
causes with Ganesh:
1. The input coordinates of some of the cube faces have 0 or negative ws.
- When negative, the current bounds code does not perform clipping and
just uses the mirrored point, which leads to misleading bounds.
- When 0, the current bounds code produces infinities, and then GrOpsTask
discards the op with non-finite bounds.
2. The anti-aliasing code also ignores w <= 0, and so all of its screen
space math is incorrect.
This causes a mix of completely discarded draws and distorted draws on the
GPU backend.

Without the changes to GrShape and GrAAConvexPathRenderer, this new GM
would not draw the red circle at the center when using Ganesh. Raster
drew the red circle. The difference came about because they checked
convexity after transforming by the view matrix, and Ganesh checked
before.
With this particular path construction and the very large scale factor
on the CTM, the convexity calculator in local space computed small
enough edge vectors that it thought the contour backtracked on itself
instead of winding in a consistent direction.
The GrAAConvexPathRenderer would claim it could draw the convex path,
but later when actually preparing to draw, it would do nothing if it
turned out the convex path didn't have a direction. This CL updates it
so that the convex path renderer's canDraw() function matches what it
is actually able to draw.
There is the separate issue of the convexity/direction checking
precision.

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.

This is implemented at backend-neutral level and so misses some
opportunities to reduce the number of passes in the GPU backend.
Filter quality is interpreted as:
none - single nearest neighbor resampling
low - chain of bilinear resamplings. 2x up/down except for one
step which may be smaller than 2x.
medium - same as low
high - when both scale factors are up then same as low but with bicubic
filtering rather than linear. Otherwise, same as low.

This also pointed out the amount of code behind ifdefs should be

There was an issue on Android where a client was drawing a small bit of text,
and then a large chunk of text below it. On the next frame they started fading
out the text and then swapped out all of the large chunk of text. We were not
marking the Plot containing the small bit of text as still in use in this case,
so it was getting overwritten by later uploads. That bug has been fixed,
but this GM tests that codepath.

Added a GM that demonstrates the bug. Should draw a blur with
the center masked out, and a circular blurry shape that's
roughly the inverse. On raster, this was already the result.
On GPU, the blurred/eroded layer becomes a subset with an
origin other than (0,0), and that layer was shifted.
I *think* this is the correct fix - we are including 'offset'
in the texture matrices, but that's just based on the crop
rects and adjustments from each filter. We still need to adjust
the texture coords for the subsets themselves.

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.

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.
