I'd just like to point out that 32-bit Quickdraw is built into all the new
color-capable Macs since the IIci, including the IIsi & the LC.  You are
ALWAYS using 32-bit Quickdraw on these machines; it has NOTHING to do with
the screen-depth.  32-bit Quickdraw is an enhancment of the original
8-bit Color Quickdraw that fixes a number of bugs, speeds up some functions,
and adds features for dealing with color devices which can display more
than 256 colors at a time.  Using 32-bit Quickdraw on a 4- or 8-bit system
won't hurt you any, and it's more bug-free & faster than the original
Quickdraw (besides, if you view 24-bit docs, at least you have system-level
dithering now).  As an aside, 32-bit Quickdraw is built into System 7,
so all you people out there will be running it whether you like it or not
(yes, even SE/30 owners).  This makes life easier for app. writers who
want to use the new calls in 32-bit Quickdraw.
