Problem: screen and graphics file aspect ratios are different

[Tero Siili]

Hi!

In short:

1) I have a lat-lon grid whose aspect ratio (measured in degrees or
grid points) is 1
2) I am able to produce a contour plot onto the screen with the
correct aspect ratio
3) When I save the graphics to a file, the shape of the plot changes
to a rectangle
    (aspect ratio <> 1) from the square (aspect ratio = 1) on the screen

I have tried both varea and parea and they help for the screen. The
saved graphics problem persists with both printim as well as gxeps
commands.

Any pointers or advice as to what might be causing this behaviour and
how could one give the aspect ratio a fixed value for both screen and
saved-to-file graphics?
