	It's actually more of a 'kludgy hack' than you realize...In a fit of
insanity a couple of us decided to disassemble the 32bit QD file to find out
how it is doing the color icon on the desktop.  Boy is it a BIG HACK!
	What they do is patch CopyBits (since that is how the Finder (and many
other apps) draw their icons).  The patch checks the bitmap.bounds to see if it
is a 32X32 square (an icon).  If it is then it does (heres the best part) a
BIT BY BIT COMPARISON of the bitmap to draw vs. their HARDCODED bitmap.  (just
change their icon in the slightest and watch the color dissappear...)
	Thought I would pass on this wonderful info so you could all give Apple
the bronx cheer on this one...Now if only I could write code like that and have
it approved by my boss :-)
