This is required to Xineramify the Damage extension, since we need to collect regions across screens. You can't quite use FlushCallback for this since WriteEventsToClient can itself trigger FlushCallback and you recurse.
There are probably other cases where this would be useful though, for example some of our abuse of BlockHandler may want to move to this callback.
