What I haven't seen anyone say yet is that with WinMegaPOV,
you can use a camera like 
camera	{
	location -z 
	right image_width/image_height*x //<---------<<< important
	look_at 0
	}
 and no mater what you set the width or height of the image to,
it is like looking through a window, just shaped differently. The
image doesn't distort. Without the right image_width/image_height*x
part, the image just gets squashed one way or another. I keep several
ini files that are each contain one aspect ratio at various sizes.
All I need do is select the ini file I want and then the image size.
The camera statement keeps it looking proper. My personal feelings is 
that this should be the default action with the use of right in the 
camera statement as a means of overriding the default. i.e.. you only 
use right if you want to distort the image.

Oh, thanks for the different aspect ratios. New ini's are on the way.
