Well, the new function calls are documeted in the API docs, but 
there is no overview.

Screen migration is simply gtk_window_set_screen (window, new_screen)
there is no way to trigger it external from an app currently.

It's not needed for Xinerama, but there are still people who
run non-Xinerama multihead. Also, migration between different
displays, not just different screens on the same display is
possible.

There would have to be a new convention involving probably
ClientMessages sent ot an app to drive migration.
