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.

longer support OS versions older than iOS 10.0 and MacOS 10.13. And
because of the shader compilation issues we are no longer testing nor

bumped up to MacOS 10.14.

1. Removes clamping of spotlight's specular exponent, which is not the
specified behavior of feSpotLight in SVG.
(note: we never clamped a specular lighting effect's
specular exponent/shininess parameter, although SVG 1.1 does clamp
that; that is the client's responsibility).
2. Fixes a bug in the GPU implementation of scale factor for spot lights.
3. Saturate computed lighting color after multiplying with color scale,
instead of just saturating the color scale (allows high intensity
lights to saturate to white which is more reasonable approximation of
an HDR effect stored in an LDR color).
Note: fixes 1 and 2 were originally addressed in https://bugs.chromium.org/p/chromium/issues/detail?id=472849
but the change was reverted for layout failure reasons and it was never
relanded after rebasing.
Note2: most of the layout test rebaselines necessary for chrome are
minor and related to fix 2. The exception is svg/dynamic-updates/SVGFESpecularLightingElement-dom-kernelUnitLength-attr.html
which is the result of fix 3. It took a little digging, but I believe
that fix 3 actually makes that generated SVG more correct (it's original
expected image was "wrong").
In that test, it has a specular constant of 4 (which is a multiplier)
and a shininess of 1 (which makes it practically a "diffuse" specular).
So basically we are multiplying the greenYellow color by 4 for most of
the image that has a normal pointing out of the screen. Firefox renders
a similarly yellow oversaturated appearance instead of clamping to the
base greenYellow.
Reading the feSpecularLighting spec, there is no saturation that is
specified where it had been performed before this change. Instead, all
that is mentioned is that the results of a given filter have to be pinned
to the color channel range (e.g. the last step).

fills.
I debated always forcing it to true, but dithering was never turned on
for the turbulence filter and it's not necessary for const color shaders
Given that, I opted to just make it a parameter to the filter factory,
which seems okay since we're unlikely to embed dithering into SkShader
itself, it's a shading-related parameter of SkPaint, and if we migrate
to always dithering, then we can remove it.
