cc: Handle directly composited images in impl-side painting

Directly composited images are recorded into an SkPicture just like normal
content.  This also means that (at the moment) they will be treated like
normal content, such as getting low-res versions.  There will need to be
some future follow-up to make sure that tiny images that end up large
on page don't take up unnecessary GPU memory.

The only bad part about this path is that changing a layer's bounds forces the
content to need to be re-recorded and re-rasterized, as there's an assumption
that the composited image fills its entire bounds.  This could be fixed in the
future by adding another layer (haha) of indirection.
