Adds speed control into the SDL build.
...
If I can just figure out how to manipulate OpenGL from the timer thread to SDL's satisfaction, this'll be as good as it probably gets via SDL.

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.

At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.
