I don't understand this at all.  I understand 'macros' in SDL (I think)and I
just looked at the POV documentation on functions, but don't see how one
can be used in this way.  If anyone can dig up a simple example I'd
appreciate it.

Yea, I thought of this afterward too.  It just seemed more laborious to code
than I wanted to get into.  heh.

I like this idea!  As you say, if the initial spacing and magnitude of
subsequent randomization are selected correctly, there is no need to check
anything.  Very nice.  Thanks.
