Ensures no input data is dropped when changing output rates.
...
I think this 'completely' deals with the problem. At least until someone wants dynamic output buffer sizes or something like that. We'll see.

This eliminates an issue with dynamic rate matching and throwing away the beginnings of buffers.

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.
