This FAQ was a great learning experience.  I want to thank Joel
Kollin, Bob Burnstein and Paul Schwartz for taking a look at my work.
I also want to thank Mike Bevan of VR News and Roy Latham of Real Time
Graphics.  Without the original information that they produce
_annually_, this wouldn't exist.
