I don't think I agree with changing the worker's image_compression value in
_handle_preferred_compression(). I think that the line you added in this patch
should replace the existing one, not be in addition to it.
The preferred compression value is very much a client-specific thing. Currently
we only support a single client, so it doesn't matter very much. But if we did
add support for multiple clients, we wouldn't necessarily want the preferred
compression of one client to affect the compression value for other clients.
right?
