From the Laser C manual:

"Any rectangular area of the screen can be invalidated by calling form_dial
with a value of FMD_FINISH.  The rectangle will be redrawn by a series of
events for all windows covered by it."

Actually, that's a nice solution.  Memory-hungry is may be, but it is a much
faster solution.
