Details:

Run the attached script mk_linewidths to generate a table of lines where the
linewidth is equal to the y-value.  For linewidths greater than 5, Octave just
draws a width=5 line.  See the attached pictures made with the FLTK and
gnuplot toolkit.  gnuplot correctly keeps growing the line as the linewidth is
increased.  Also, note that this is only an on-screen drawing issue.  Printing
the plot to a file, which uses gl2ps, correctly scales the line.
