Tessellation uses infinity to flag conics, and also as a conic weight
that converts them into triangles. The es2 shading language doesn't
support infinity. This CL adds a "portable infinity" mode, where we
pretend inputs >= 2^126 are infinity. The rationale for doing this is
that those numbers are so large, they will overflow if we try to do any
bezier math with then anyway.

Like SkColorFilter, SkShader, etc., this has a public-facing component
(SkBlender) and a private subclass (SkBlenderBase) which can be
obtained via a helper function (as_BB). At present there are no public-
facing methods, but the type needs to be exposed to be usable by the
outside world.
These classes exist for SkRuntimeEffect to subclass. The blender base
provides a `program` method with the parameters that blending will use.

At present, only Xfer processors allow reading back from the destination
image since they are in charge of blending. However, we'd like to expose
the destination color to fragment processors and Runtime Effects in the
future. To make this possible, the DstProxyView will need to be
accessible outside of Xfer processors.
This CL migrates DstProxyView to be a top-level Ganesh class and fixes
up the references to it throughout Skia. It's interesting to note that
several call sites were already using typedefs to hide the class
nesting anyway.

- 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).

Chromium has been updated to use makeAnalysisCanvas directly and there are
no more references to SkTextBlobDiffCanvas as a type in its code base.
Since the GlyphTrackingDevice extends SkNoPixelsDevice, any SkCanvas that
uses it is effectively a "no-draw" canvas. However, by returning a base
SkCanvas the text tracking now automatically happens in the context of
the base's AutoLayerForImageFilter handling it applies on every draw. This
means that drawing a text blob with an image filter that modifies the
transform state will now be analyzed in that context automatically
(simplifying code in chrome after this lands).
Another behavioral change is that all non-text draws will still go through
the base SkCanvas' virtuals and invoke the device function. Since it's an
SkNoPixelsDevice, it'll still be a no-op, it just happens a little later.
This won't really impact performance because oop-r already inspects their
operations and only plays back text and transform related ones to the
analysis canvas, so we shouldn't really see non-text draws being invoked
anyways.

The SkM44::RectToRect function matches the semantics of
SkMatrix::RectToRect(kFill_ScaleToFit). No other ScaleToFit variants are
ported over to SkM44.
skottie uses some instances of kCenter_ScaleToFit so that functionality
may need to be added in the future (in SkM44 or in skottie). There are
no current usages of the kStart and kEnd_ScaleToFit semantics.
The SkM44::mapRect() function is implemented to correspond to the
SkMatrix::mapRect() that returns the mapped rect (instead of modifying a
pointer) and always has ApplyPerspectiveClip::kYes. This was chosen to
keep its behavior simple and because perspective clipping is almost
always the right thing to do. In the new implementation there is no
longer a performance cliff to worry about (see below). For the timebeing
mapRect is hidden behind SkMatrixPriv::MapRect().
Performance:
I added benchmarks for mapRect() on SkM44 and SkMatrix that use the same
matrices to get a fair comparison on their different specializations.
SkMatrix has a very efficient mapRect when it's scale+translate or
simpler, then another impl. for affine matrices, and then falls back to
SkPath clipping when there's perspective. On the other hand, SkM44 only
has 2 modes: affine and perspective.
On my desktop, with a Ryzen 9 3900X, here are the times for 100,000 calls
to mapRect for different types of matrices:
SkMatrix SkM44
scale+translate 0.35 ms 0.42 ms
rotate 1.70 ms 0.42 ms
perspective 63.90 ms 0.66 ms
clipped-perspective 138.0 ms 0.96 ms
To summarize, the SkM44::mapRect is almost as fast as the s+t specialization
in SkMatrix, but for all non-perspective matrices. For perspective matrices
it's only 2x slower than that specialization when no vertices are clipped,
and still almost 2x faster than the affine specialization when vertices are
clipped (and 100x faster than falling back to SkPath).
Given that, there's the open question of whether or not keeping an affine
specialization is worth it for SkM44's code size.

This new tessellator renders strokes as fixed-count triangle strip
instances. Any extra triangles not needed by the instance are emitted
as degenerate triangles. Since it draws in order, this tessellator
allows us to batch dynamic colors even when hw tessellation is not
supported.

These enforce stricter rules about the signature of main, and each one
uses a separate pre-include module. That prevents color filters from
being able to reference sk_FragCoord (or coords passed to main) at all.
It also limits the versions of sample() that are exposed.
In the new world, an effect created for a specific stage of the Skia
pipeline can only be used to create instances of that stage (SkShader or
SkColorFilter). For now, SkRuntimeEffect::Make uses kRuntimeEffect,
which continues to be more lenient and allow creation of either shaders
or color filters from a single effect. After we migrate all clients, we
can deprecate and then delete that mode.

For now, just bolt this onto the existing runtime effects. The next step

Our benchmarks had drifted away from actual codegen in several ways, and
were no longer representative of actual output. In particular, every
function in the existing benchmarks used a scratch `_output` variable
which would make it ineligible for return-statement-only inlining.
Updated the tests to match modern codegen. `small` and `large` use the
same sources as before. The code from `medium` is older and had diverged
quite far from today's output; I could not find a representative code
snippet at all. It has been replaced with SkSL of roughly similar
complexity.

This is useful because it allows the variables to be declared as `const`
when they are trivial values like `half4(1)`. This enables the constant
folder to simplify or eliminate them. In most cases, this is only a
small benefit, as you'd expect a competent GPU driver to do the same.
However, Mali-400 can benefit significantly from optimizing away the
multiplication against a constant half4(1) coverage in Porter-Duff.

Adds quick accepts to the switch statement in
GrStrokeHardwareTessellator::prepare() that allow us to write out most
tessellation patches immediately. This avoids making function calls
into recursive methods as well as avoiding some of their checks that
aren't necessary the first time around.
Also adds a microbench that mimics the MotionMark "paths" benchmark
and measures our CPU-side prepare() time.
This shaves up to 30% off the microbenchmarks.

The intent of this class was to abstract the internal linked list used
by GrStrokeTessellateOp, but it seems to just make things more
complicated. We have a need now to iterate the list with more freedom
than is offered by GrSTArenaList, so it seems best to just use a plain
C-style linked list instead.

This change will allow these types to be forward-declared; C++ doesn't
allow forward declaration of types declared inside a struct. Moving
these types out of Programs resulted in a large diff.
The Settings::Value helper class has been moved inside of the
IRGenerator. In practice, it was actually just an implementation detail
of how IRGenerator looks up caps-values by name. It seems very unlikely
that this will be necessary elsewhere going forward.
