This CL implements Go bindings for a subset of the functions in the C API.
It implements a Go version of the C demo program in
experimental/c-api-example/skia-c-example.c and the output is identical.
(Checked by hand).
The main purpose is to establish a pattern of calling the Skia C API that
is memory safe and provides a idiomatic Go interface to Skia.
Follow up CLs will cover the entire C API, add documentation and establish
a pattern to distribute the bindings more easily.

When drawing an analytic rrect shadow, the mask filter could pass
the devRect into the drawOp. If we have a small scale that could
make the radii less than SK_ScalarNearlyZero. We might also have
a rect that we outset by a value less than SK_ScalarNearlyZero to
the penumbra border. So the best we can check is that the the two
radii are equal.

GrDefaultPathRenderer was using GrPathUtils::worstCasePointCount, which
clamped the tolerance. Then it built geometry with the unclamped value,
leading to vertex overflow (found by canvas fuzzer). The new rule is if
you use GrPathUtils, your tolerance must come from scaleToleranceToSrc.

This is one of the leaf nodes to getting SkCreateRasterPipelineBlitter

This makes SkColorFilter::appendStages() first try onAppendStages(),
and if it's unimplemented or fails, fall back to filterSpan4f().
This also makes onAppendStages() private to try to ensure that
appendStages() is now its only caller, ensuring everyone goes
through this fallback path.
The fallback uses the color filter transformed into the dst colorspace
using our new SkColorSpaceXformer... that seem ok Matt?

There has been a supported() function in SkRasterPipelineBlitter.cpp for
a long time that's becoming increasingly misnamed. That blitter ought
to be able to handle all destination formats.
This CL moves that logic outside to the creator of the blitter, changing
it from "can we handle this format?" to "do we want to use this blitter
for this format?".
In other CLs I'm working to make creating a pipeline blitter never fail.
