    Hmmm, I was positive the 80x86 CPU's all had 32-bit data paths... we sure
could use a quick GIF decoder (and encoder) for slide shows and other GIF
viewers.  Jonah's GIF.3200 clocks in at around 15 seconds for a 320x200x256
GIF on an unaccelerated GS.  That blows away SHRConvert 2.1, but it can be
faster yet.

    We'll be right here waiting.
