Markus is now using CopyBits, instead of the 'picture' command, to  
draw (most of) the PICT resources for his game.
The game loop is throttled by inkey$, which is called once each frame.
frame time = inkey$ time + calculation-and-drawing time
By default, inkey$ time is 2 ticks = 1/30 s (the same as the default  
HandleEvents time).
If my arithmetic is right, calculation-and-drawing time has dropped  
from 0.022 s per frame to 0.012 s per frame, nearly twice the speed.
