Yeah, I think that's a good idea.  I will do that for the fft routines.

On the other hand, a quick peek seems to show that implicit_plot and
draw (in gnuplot.lisp) have exactly the same implementation of
print-square; it looks like one copied from the other.  It certainly
would be nice to refactor that as well.  Don't know how that would
work in practice.
