this is a very useful option, similar to that of the "axis image" of
matlab. a small wish from me: is it also possible to let the option
"freeze" the aspect ratio of the figure(s) in question when the window
is resized? this is like the matlab behaviour for "axis image", e.g.
when the window is enlarged in such a way that the aspect ratio of the
window changes, the aspect ratio of the figure(s) remains the same
while the increase.
