6edc8d9617 Remove 'hasUserStencilSettings' from GrClip::apply
This doesn't seem necessary. Its only purpose was to disable analytic
clips when there were user stencil settings, which seems like a
de-optimization. The ops that use stencil all seem to properly handle
clip processors in their color pass, so it should be fine to remove
this.

569c01bfa2 Simplify heuristics for selecting path tessellators
Now that hardware tessellators chop, support raw triangles, and can
handle any path, we don't need complicated logic anymore to determine
when we can't use them. This CL simplifies the criteria for selecting
a tessellation algorithm and adds a fAlwaysPreferHardwareTessellation
context option to override it.

4e9d5e2bdf Use Wang's formula for quadratic and cubic point counts
- most of the small diffs are because I moved GrWangsFormula.h out
   of the tessellate/ directory and into the geometry/ directory since
   it's more general than HW tessellation.

The previous implementation was based on the heuristic that the distance
from the true curve to the line segment would be divided by 4 every time
the curve was recursively subdivided. This was a reasonable
approximation if the curve had balanced curvature on both sides of the
split. However, in the case of the new GM's curve, the left half was
already very linear and the right half had much higher curves.

This lead to the approximation reporting fewer points than required.
Theoretically, those few points that weren't utilized by the left half
of the curve could have been made available to the right half, but the
implementation of that would be tricky.

Instead, it now uses Wang's formula to compute the number of points.
Since recursive subdivision leads to linearly spaced samples assuming it
can't stop early, this point count represents a valid upper bound on
what's needed. It also then ensures both left and right halves of a
curve have the point counts they might need w/o updating the
generation implementations. However, since the recursive point
generation exits once each section has reached the error tolerance, in
scenarios where the prior approximation was reasonable, we'll end up
using fewer points than reported by Wang's. Hopefully that means there
is negligible performance regression since we won't be increasing
vertex counts by that much (except where needed for correctness).

3e8ff3ef61 Fix vertex alpha when connector edges intersect inner edges
In the new GM, the left and right portions of the path have a shared
vertex. The two edges leaving that vertex vertically towards the bottom
of the image are nearly parallel but the right edge has a steeper slope.
This leads to two sources of self intersections. The outset vertices
for the left and right sides intersect, which converts some of those
edges into "connecting" edges and removes others (preventing double
hitting of pixels). However, these outset but now "connecting" edges
from the right side also overlap with the inset vertices of the left
shape, requiring additional vertex splitting and connecting edge
creation.

The old alpha logic when one of the intersecting edges was a connecting
edge was to use its interpolated alpha value. In this case, since the
connecting edge originated from two outset vertices, its end point
alphas were 0 and the split alpha became 0, even though the other
intersecting edge was an interior edge.

This CL flips the logic around and ensures that any split vertex that
is on the interior edges remains fully opaque, any vertex that is
fully on the exterior remains fully transparent, and anything else
uses the max of the interpolated alphas (equivalent to the old
logic when one edge was connecting and one was exterior, but is more
accurate if somehow we get two connecting edges intersecting).

e49703faf2 Remove custom SkVertices data and runtime effect varying support
This was an experimental feature. It worked (but only the GPU backend).
It was never adopted or used by anyone, to my knowledge. It's a large
amount of code, and a strange corner of SkSL for users to stumble into.

cc3d2d25c5 Runtime effects: Detect passthrough sample calls automatically
As explained, this is *very* conservative. It only works when the child
is sampled from within main, and using a direct reference to the coords
parameter. If that parameter is ever modified (even after being used),
the optimization doesn't happen. For most cases, this is fine.

These are rounded rectangles whose corners are superellipses instead

define a consistent, visually appealing shape that can be used

70fae35842 Preserve winding scale for outer edges in AA triangulation
More details are in the bug, but the specific test case gets an
overlap region in the AA outset geometry for the left and right shapes.
Additionally, the mitered outset for the left shape is collinear with
the bottom of the right shape, so the winding of exterior edge of
the overlap region is updated to +2.

When determining the polygons to fill, this +2 on the outer edges
violates the winding rules that normally ensure the interior polygons
(that use +/-2 instead of +/-1) are always filled.

It appears a similar bug fix was added here:
https://skia-review.googlesource.com/c/skia/+/141952/
but then didn't survive a heavy refactor later:
https://skia-review.googlesource.com/c/skia/+/215094

To the best of my knowledge, this is achieving the same result as the
original fix but is updated to preserve winding scale for interior
polygons with overlap regions (the code checks for these, but they
seem pretty rare to me).

577c6067a1 Runtime effects: Support input color as a parameter to main()
For now, just bolt this onto the existing runtime effects. The next step
is to add dedicated modes to the compiler for shader vs. color filter.
Once we get there, we will be much more strict about main signature in
each mode (and start adding other per-mode error checking).

This reverts commit 92b35673c5.

Original change's description:

>
> This CL adds a "pathsForClipAtlas" array for GrClip::apply to fill out

> FPs once it knows exactly which opsTask they will belong in.

Atlas clips always had a potential point of failure: If the SDC's
opsTask ever got closed between GrClip::apply and
GrOpsTask::addDrawOp, their mask would have gotten sent to the wrong
opsTask. It didn't _look_ like this could happen with the current
code, but it could have also been inadvertently changed quite easily.

This CL adds a "pathsForClipAtlas" array for GrClip::apply to fill out
instead of creating FPs. The SDC then generates the actual clip atlas
FPs once it knows exactly which opsTask they will belong in.

Only the largest sigma (320) would hit the downscale limit with the
old sigmas and image sizes. However, that sigma was far too large
to produce reference values in a reasonable amount of time.

Reduce the image sizes so that the downscale limit can be hit with a
smaller sigma.
