Original commit message from CVS: * examples/play.py: * examples/remuxer.py: * examples/switch.py: * examples/synchronizer.py: Sync with the X server before giving an XID to our sink with a different display connection. This avoids spurious X servers where the sink's display connection doesn't know the XID that the GDK thread's does.
