Put a wrapper around the media texture region serialization 

THIS WILL BREAK EXISTING MEDIA TEXTURE PERSISTENCE.  Please delete your existing sqlite databases if you are experimenting with this branch.
This wrapper will make it easier to maintain compatibility if the media texture data evolves.
This will also make it easier to store non-sl media texture data.
