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

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.
Mali-400 performance is back to normal: http://screen/3cDxdaGkYE8oBcS

point further uses of the image will use the copy. If the image is ever
used off a GrDirectContext we fall over to the copy. If the copy is
never used and never can be used by the next flush then the render
task that populates it is marked "skipped" and we don't perform the

Small diffs in a GM -- due to the dual nature of kMedium (cpu and gpu)
Another reason to stop using it, and switch to the more-explicit
sampling.

Implement support for COLRv1 color gradient vector forms. COLR v1 is an
extension to the OpenType COLR tables that introduces support for
gradients, transforms and compositing. [1]
COLRv1 fonts contain an OpenType COLR table with format v1. In a COLR v1
table, glyphs are defined by a directed, acyclic graph of Paint
operations. The task for the Skia implementation is to extract the COLR
v1 information from the font using FreeType's COLRv1 API, then traverse
the glyph graph and translate information from the font into Skia
operations on SkCanvas.
Care needs to be taken for transformations to work correctly. FreeType
sends a top level transform that includes the scaling from font units to
actual glyph size, as well as optional transforms configured on FreeType
using FT_Set_Transform. This is set up as the starting transform at the
beginning of drawing a COLRv1 glyph. At the stage of setting a clip for
a PaintGlyph operation, the glyph outline is retrieved from FreeType
unscaled and untransformed. Since the starting transformation is applied
to the SkCanvas, the unscaled glyph is properly scaled and positioned.
Similarly, computing the initial bounding box for the COLRv1 glyph needs
to consider transformations. COLRv1 glyphs have a base glyph entry in
the glyf table which can use a minimum of two points for defining a
bounding box. This bounding box is an imaged rectangle enclosing those
two points at the identity transform. We need to compute the bounding
box scaled, but at identity transform, then make a rectangle from it,
that we then transform so that we get a large enough area to paint
in. If those two points from the glyf table would be transformed first,
then we would compute the bounding box, the resulting bounding box ends
up too small.
As a test font, add a version of the samples-glyf_colr_1.ttf from [2]
with one glyph added for testing PaintColrGlyph functionality and
compositions.
Add a basic GM test that produces color glyphs untransformed, with
skew and with rotation and combinations of those.
