If I output a postscript file, I get the wrong aspect ratio, but if I out a .png file via ImageMagick, I get the right aspect ratio. Even weirder is that if I set ps_delete=0, the intermediate postscript file has the *right* aspect ratio. I've looked at the code in both sections, and I can't see any difference that could account for it... and if I try to manually run the commands that create
the ImageMagicked .png file, I get the wrong aspect ratio!

My fault. I need to make the resizeable graphics window
the current graphics window before I call PS_Start,
so that PS_Start will get the proper window aspect
ratio. It was using the default window aspect ratio,
rather than the correct one.

I'll update in just a few minutes. I'm right in the
middle of writing some notes for the new Get_Keyword
functionality for cgControl.

Cheers,

David
