Enables and disables "snow-checking" when storing characters directly in video memory

When a color text mode is selected, CheckSnow is set to True, and direct video-memory writes will occur only during the horizontal retrace intervals.

If your program is running on a newer CGA, you might want to set CheckSnow to False at the program's beginning and after each call to TextMode.

This will disable snow-checking, resulting in significantly higher output speeds.

CheckSnow has no effect when DirectVideo is False.
