| The current png driver (really libgd itself) only
| stores the colors actually used by the plot.

This patch is for user who want the same color behavior in png 
term as in x11 term (or win term) without setting

  set term png xffffff x000000 x404040 \
  xff0000 x00ff00 x0000ff xff00ff x00ffff xa0522d xffa500 xff7f50 \
  xff0000 x00ff00 x0000ff xff00ff x00ffff xa0522d xffa500 xff7f50 \
  ...

On current png term, line type 9 is not red under the simple 
setting:

  set term png xffffff x000000 x404040 \
  xff0000 x00ff00 x0000ff xff00ff x00ffff xa0522d xffa500 xff7f50

and the result of test command differs from the one on the x11 
term.

We found some requests on "Gnuplot Q&A board"

 http://ayapin.film.s.dendai.ac.jp/cgi-bin/trees.cgi  
 (in Japanese)

to set the same colors in png term as in win term. My patch may 
help them.
