I have found that the graphics routines in both Turbo C 1.5 and 2.0 are
VERY slow.  They are not optimized for a specific graphics board.  They
are general for all graphics boards.

If you are having problems keeping up with the mouse, try (as a test)
timing how long it takes to plot a dozen horizontal lines a few hundred
pixels long each one pixel at a time.
