As we have factored things, we _do_ need to map y. This matrix maps us
back from dst to src space now, but not all the way to t.
We let the subclass inject its own logic for x,y -> t.
(Linear gradients do actually still do this by modifying the first
matrix rather than appending another matrix for x,y -> t. But in
general we cannot not map y here anymore.)

Mostly this is about extending the fallback in SkShader::appendStages()
to cover more cases, and making sure subclasses call appendStages() so
they can get the fallback, not onAppendStages() directly.
We still need to watch for SkShader::makeContext() failing in the
fallback itself, so sadly SkShader::appendStages() may still fail.

Many SkShader subclasses are only friends to use makeColorSpace().
Our usual solution to this is to add a method on SkColorSpaceXformer
that calls makeColorSpace() for us, so that only SkColorSpaceXformer
needs to be a friend.
Just a refactor. No image diffs.

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.

This also makes onAppendStages() private to try to ensure that

The fallback uses the color filter transformed into the dst colorspace
