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.

This is less to type in most cases, and gives us more information
(for things like picture-backed images, where we need to know all
about the destination surface).
Additionally, strip out the plumbing entirely for bitmap sources,
where we don't need to know anything.

ClipPaths can be clipped too, e.g.:
<clipPath id="clip1" clip-path="url(#clip2)">...</clipPath>
Since we're not really drawing clips but resolving their geometry,
asPath() needs to take composed clipping into account (and intersect as
needed).

There's a bit of friction with this attribute, because per spec it is
an inherited presentation attribute, but in Skia it is part of the
actual SkPath state.
So we must add some plumbing to SkSVGShape & friends to allow overriding
the fill type at render-time.

Many places that construct one are explicitly specifying opaque white or
transparent black, which we can assume (based on the semantics of the
operation) should remain (0,0,0,0) or (1,1,1,1), so that's simple.
In other cases, we convert our source color to destination space.
One wrinkle is tht SkColorFilter now needs to know the destination color
space, due to SkModeColorFilter.
