After the discussion in [1] which was filed also in response to feedback
from Ben, the COLRv1 spec moved to not using a bounding box derived from
the `glyf` glyph for a give glyph id, but instead either use a ClipBox
found for a particular glyph id range from a ClipList array in the
COLRv1 table. If such a ClipBox is not found, perform a traversal of the
COLRv1 graph to compute the union of rectangles to compute a bounding
box.

Adds a GM reproducing triangulator failure. The stroker generated
geometry shown in the GM had two edges intersecting on the inner
contour. One of the edges was practically vertical, such that its top
and bottom vertices X coordinates differed by 1ulp (approx 4.8e-7 when
x = 7.5). The intersection was computed correctly in double but then
clamped to exactly 7.5 when stored back in float at (7.5, ~11), which
is still a reasonable intersection point along the edge represented
by (7.5,0) to (7.5000048,~68).
However, with a sorting direction of horizontal for the vertices,
vertices are sorted on increasing x and then *decreasing* y. The
computed intersection is then technically above the edge's top
vertex. In the original code, the edge was not considered flat, so
it assumes that the intersection vertex is below the top vertex
and above the bottom vertex.
The issue was with the nearly_flat function only checking the difference
against machine epsilon without taking the magnitude of the vertices
into account. However, just changing nearly_flat to use ulp instead of
epsilon led to infinite recursion and asserts on a number of tests due
to inaccuracies in edge intersection tests. To address these issues,
I reworked clamp() to work on X and Y independently, which avoids the
need to check nearly_flat entirely. Additionally, edge intersection
detects when it might be inaccurate due to really large vertex coords
and recursively splits to reject false positives.

AndroidFramework uses both their own custom display list (which could
handle resetClip with android-side changes) AND conventional picture
recording. In order for replace op emulation to work when they have
been recorded into a picture, we need to make it virtual and supported
in SkPicture.
This also renames the API to ResetClip() from ReplaceClip() and does not
have any additional arguments. Based on AF's usage pattern, it only n
needs to reset the clip to the surface bounds or the device clip
restriction, it seems best to reduce the API as much as possible before
it's adopted.

Previously, DSLVar represented local, global, and parameter variables.
This splits it into three separate subclasses.
In addition to just being a cleaner API in general, this also addresses
an issue we ran into with the upcoming DSLParser: previously, a global
DSLVar's storage was not set correctly until DeclareGlobal was called,
so an AddToSymbolTable call prior to DeclareGlobal would create the
SkSL variable with the wrong storage, causing spurious errors on
global-only modifiers. But holding off on the AddToSymbolTable tends to
break constructs like "int x = 0, y = x", so improving the API seemed
like the best way to address it.
Now that we have greater type safety around variables, we can
potentially avoid having to call AddToSymbolTable for DSLVar and
DSLGlobalVar altogether, since we know they are both supposed to end up
in the symbol table, but that isn't something I want to change in this
CL.

Also disables hairline mode for rects that are not fully anti-aliased,
which showed up in the fast_constraint GMs where we'd tile an image and
the bottom/right edges were actually subpixel. Since the objective of
per-edge AA is for tiling, we don't want those subpixel edges to be
outset more than the original geometry would have been in a non-tiling

... to aid in removing special ArithmeticImageFilter.
Can we use something like this to reimpl the ArithmeticImageFilter
--> BlenderImageFilter?
I see some special checking in filterBounds for ArithIF -- is that
required? Is that generalizable for any BlenderImageFilter?
If we can generalize blend[er]imagefilter, let's just move this
logic into Chrome -- no need for Arithmetic to appear in Skia
in any form!

Rewrites tessellation atlases as normal render tasks instead of
"onFlush" tasks. These tasks get inserted into the DAG upfront, lay
out their atlases as dependent tasks get built and reference them, and
finally add their ops to render themselves during onMakeClosed. Doing it
this way allows us to pause the flush and re-render the atlas whenever
it runs out of room.

This CL migrates DstProxyView to be a top-level Ganesh class and fixes

several call sites were already using typedefs to hide the class

- 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).

* Make sure to actually use hardware tessellation on the *_tess_segs_5
gms. These had started using the fixed count tessellator.
* Add a trickycubicstrokes version with round caps to test upcoming
coverage AA modes.
* Make the colors more appealing since I spend all day looking at
these gms.

This effectively reverts a80ce1a36d,
and goes back to using SkMakeSpan (which works in C++14).

This makes them easier to integrate with other shader code than having
them in GrGeometryProcessor.

This is a reland of adadb95a9f
... adds a temporary workaround for some Android framework code.
Original change's description:
> Better first-class shader & color filter support in runtime effects
>
> This does a few things, because they're all intertwined:
>
> 1) SkRuntimeEffect's API now includes details about children (which Skia
> stage was declared, not just the name). The factories verify that the
> declared types in the SkSL match up with the C++ types being passed.
> Today, we still only support adding children of the same type, so the
> checks are simple. Once we allow mixing types, we'll be testing the
> declared type against the actual C++ type supplied for each slot.
> 2) Adds sample variants that supply the input color to the child. This
> is now the only way to invoke a colorFilter child. Internally, we
> support passing a color when invoking a child shader, but I'm not
> exposing that. It's not clearly part of the semantics of the Skia
> pipeline, and is almost never useful. It also exposes users to
> several inconsistencies (skbug.com/11942).
> 3) Because of #2, it's possible that we can't compute a reusable program
> to filter individual colors. In that case, we don't set the constant
> output for constant input optimization, and filterColor4f falls back
> to the slower base-class implementation.

This adds an explicit DeclareGlobal call, which must now be called for
variables that were previously implicitly global.
