While we're on the subject, the vncviewer also fails to work properly in
some variously-endian situations. Specifically, I've seen it produce
mangled colours when running vncviewer on a little-endian box and a
big-endian X server (an x86 Linux and MI/X on a Mac, respectively). I
think I also saw it fail in a similar manner when running on a Sparc and
using MI/X for Mac as an X server, too, but that was a long time ago and I
haven't tried it recently.
