I'm inclined to think that somehow the area of interest and the size
of the image are not kept in synch, or something like that.
The WMS spec says that if you ask for an image which is out of
proportion compared to the geographic area depicted, the output
should be correspondently distorted.
So the renderer follows that, if you ask to paint a square envelope like
(10,10 20,20) into an image that's 100 x 200 you'll get a distorted
output.
