It would be nice to clean this one up too, since the semantics don't really make
it clear whether the caller is handing you a ref or not.  I don't think we
should use skia::RefPtr, since it's in the WebKit API, but jamesr might know a
good approach (hide it in an opaque pointer-owning class, or something?)

Oh! I see the graphics layer is sticking its pointer in a SkAutoTUnref, so it's
not passing its reference. I'll add a call to ref() here.
