While we're refactoring how gradients work it's going to be easier
to centralized how and when we tile.
- PS2 changed linear and radial in place to alwys clamp.
- PS3 moved tiling to the base class, where it's even harder to
screw up. Sweeps don't need but don't mind tiling.
- PS4 clamps when iff evenly spaced
PS4 has image diffs for only a few GMs that I'm not familiar with.
If its logic reads as correct to you, they may be bug fixes?

1) Only store GrColors in GrTextUtils::Paint. We still store
premul and unpremul versions, but this is slightly clearer.
2) GrTextUtils::Paint also needs info from the render target
context to linearize and transform the color to dst space.

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.

We've been transforming the gamut after running the legacy shader,
but now that we have SkColorSpaceXformer, we can transform the

This should be both more correct and faster.

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.
