Well, if you want to get _really_ picky, then you have to realize that
(on the mac, at least) an icon also has a mask, which is another 16*16
bits.  That makes the total number of icons:

	2^(16*16+1) = 231,584,178,474,632,390,847,141,970,017,375,815,706,539,
                          969,331,281,128,078,915,168,015,826,259,279,872

OK, anybody else want to show off the fact that they can use LISP to
calculate insanely large integers?

In San Francisco, you can bay at the moon or moon at the Bay, but it doesn't    make much difference which.                                                     Disclaimer:  Hey, what do I know?  I'm only a grad student.
