    Actually, the beta version of QuickerDraw I have (0.9) speeds up
4 bit color as well! I did a series of timings on a color version
of our flight simulator, which does a lot of color polygon fills
and CopyBits calls. I found an about 50% improvement in the
CopyBits calls and smaller gains on the poly fills and line
drawing, in both 4 bit and 8 bit color. Overall frame rate
improvement was about 25%, a little better in the 8 bit mode.
The 8 bit mode was still significantly slower than 4 bit.
     I haven't done any timings in 2 bit or black and
white yet.
