Original change's description:
> [Paint Preview] Compositing Service
> 
> Adds a paint preview compositor service for compositing collections of
> SkPictures representing frames into bitmaps. This is very similar
> in principle to the PDF compositor service, but produces tileable
> bitmaps rather than a PDF.
> 
> A client to this service should start the compositing collection
> portion of the service in a utility process. The client can then
> create and delete dedicated compositor instances for each group of
> SkPictures. Realistically only one compositor will be actively
> communicating at a time. However, multiple compositors can be
> "warm" (data is deserialized and in memory for fast switching).
