Request an XSync() to the display used by dmxScreen. If now is TRUE, call XSync() immediately instead of waiting for the next XSync() batching point. Note that if XSync() batching was deselected with dmxSyncActivate() before dmxSyncInit() was called, then no XSync() batching is performed and this function always calles XSync() immediately.
(Note that this function uses TimerSet but works correctly in the face of a server generation. See the source for details.)
If dmxScreen is NULL, then all pending syncs will be flushed immediately.
