  I'd want it the other way: If you want to use a different camera aspect
ratio you have to specify it. By default the camera aspect ratio should be
preserved.

  Have you taken into account that someone rendering someone else's scene
using an aspect ratio different than what the original author intended
might end up with an image which either clips out parts of the original
image or, worse, shows undermodeled parts which were not meant to be seen?

  Shouldn't the choice of how changing the aspect ratio of the camera
affects the composition of the image be left to the author of the image
rather than the person who renders the image (given that sometimes these
are two different people)?
