Interesting.  My "man ImageMagick" doesn't discuss the options for
each command.  And "man convert" just shows one-liners for each option
(as I showed before).

My ImageMagick man page is dated:  Date: 2005/03/01 01:00:00
I'm on Kubuntu 9.04.  And you?

In any case, it looks like "-type TrueColor" might be the magic (so to speak)
that I was missing.  Still need to confirm it.
