Should we make it more consistent? As we call skColorSpace(), maybe we should
call this one skColorType(), WDYT?

In general we should not use sk prefixes in blink.
The only reason the method is called skColorSpace in CanvasRenderingContext is
to avoid a name conflict. Basically, that class has two representations: the
ColorSpace enum (which maps to the IDL dictionary) and the SkColorSpace. C++
does not allow overloads that differ only by return type.
