On worker->stop() for example, which renderes all outstanding commands
so all state is flushed to the surfaces (and thereby device memory).
This is done on vm_stop too, so I wouldn't be surprised if most surfaces
are dirtied anyway at this point. Getting notifications about
spice-server touching surfaces doesn't buy us much then.
