That is what rand()'s man page said too.  That was why I was doing the
whole int -> float -> int casting.  random() seems to a different beast
than rand().

One more thing I did not mention was that I was using that snippet of code
in a module for xscreensaver.  random() behaves different when used inside
a xscreensaver module.  It is porbably because of some of the utility
functions I am linking against.
