The implementation is inconsistent across CPU and GPU.
CPU currently always implements kStrict even when kFast is passed.
For mipmapping this means computing a set of levels from the subset,
which is an expensive.
GPU limits the texture sampling coordinates to the subset in the
base level. However, higher level mipmap pixels that map back to
a footprint outside the subset are still sampled. So GPU pays a
higher shader complexity cost without really providing the benefit
of kStrict.
We are adding anisotropic filtering, which will not work well with
kStrict, and thus will also be disabled by kStrict.

Similar to how we allow configuration of variable font configurations,
provide additional SkFontArguments to select a base palette and a set
of potentially sparse color overrides.
This is required for implementing CSS font-palette.
Modify the more_samples-glyf_colr_1.ttf to have two additional palettes,
and two additional test glyphs, one that draws with COLRv0 logic, one
that draws with COLRv1 logic and has a foreground palette index dot
in the middle. See [1] & [2] for the additions to the test font.
Add a GM which tests this on the SkFontMgr_custom using makeClone() and
makeFromStreamArgs(). The test displays the two glyphs in default
palette on the left, then with palette overrides (as in the title of the
test) on the right. The first row uses a typeface created with
makeFromStreamArgs(), the second uses one created with makeClone().

The CPU blitters use signed 32-bit offsets when gathering source pixels,
so any image larger than that can't be fully indexed. Instead, we'd wrap

On linux we need to support drm format modifiers on vulkan images. When
we have a modifier it can restrict the allowed usages/features of the
VkImage.
The current use case we have for images coming into skia that have
these modifiers are from video decoders. All these images are only used
as sampled images in draws and they have no filtering applied.
Therefore, for now, instead of tracking all format and modifier pairs
to know what is supported, we internally set these images to be external
which already restricts their use to basic in shader sampling.
Additionally in chrome, all these images are coming in ycbcr conversions
already which we treat as external.

After further discussion, using intrinsics with signatures similar to
sample keeps us looking like GLSL. However, using "sample" is still
misleading, so this adds explicit "shade", "filter", and "blend"
intrinsics. After migrating clients, the "sample" versions will be
removed.

Previously, you would declare child objects (shaders, colorFilters, etc.)
and "sample" them like this:
uniform shader input;
uniform colorFilter filter;
half4 main(float2 coord) {
half4 inColor = sample(input, coord);
return sample(filter, inColor);
}
With the new syntax, those child objects become directly callable,
reflecting the way that Skia assembles all parts of the paint (as functions)
in the overall fragment shader:
uniform shader input;
uniform colorFilter filter;
half4 main(float2 coord) {
half4 inColor = input(coord);
return filter(inColor);
}

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.
