My experience (gnuplot on Windows) is, that if the output terminal is a graphics file, the 
aspect ratio is more or less precisely 1:1. 
Using the standard output window, I have to resize the window to 1:1 with the mouse one 
time, then click in the window menue bar options/'Update wgnuplot.ini' and after that every 
next plot is 1:1. This procedure seems to work with Maxima using gnuplot as well. 
(I don't know gnuplot interna, but I guess that gnuplot has problems to precisely adopt to 
individual screen properties.)

Hi Robert,

I don't think we want this. Just take an example with xrange [0:1] and yrange [0:1000]. This 
wouldn't look really good with a size ratio 1:1.
