SCI32: Improve behaviour of screen transitions

1. Use the same throttling speed as normal frameouts. The
   old throttling speed seemed a bit too slow.
2. Exit the event loop immediately if the engine is supposed to
   quit, instead of forcing the user to wait until the transition
   has finished before quitting.
