I've been puzzled lately. I've noticed that most of our tools don't compensate
for images with an odd width, i.e. when creating a PixMap, we put an odd number
into rowBytes. This doesn't cause crashes or any other obvious problems,
although IM 5 and IM 6 (prelim) say it must be even. Is QuickDraw doing
some checking for us, or are we asking for crashes if we do some obscure
operations?
