Moves drawing into the next timer tick after retrace if sync locked.
...
... which should mean it occurs within 1/600th of a second of announced retrace, which I assume always will be less than the retrace period. So: does the frame buffer update during retrace.
This should completely eliminate tearing for machines that can be synced to the native output rate.
