Original change's description:
> Initial land of SkSL DSL.
>
> This is not 100% complete: it lacks support for several kinds of nodes
> and supports only a bare handful of builtin functions, but it
> demonstrates the core functionality and it should be relatively
> straightforward to fill in the missing pieces.
