The current version of the FAQ is very clear on this, saying "DON'T!"

First time I read it, I was like, *WHAT*?? But reading through it, I noticed
that the FAQ does make some valid points, arguing that this only works with 1:1
pixel aspect ratio; and if scenes are passed on, people may not get the shot
intended by the artist because they happen to normally use a different aspect
ratio.

The "right x*image_width/image_height" approach does *not* allow you to specify
in the scene file what aspect ratio you designed it for.

The current set of .ini and scene parameters does give you all the *freedom* you
may ever need - but it is poor at specifying *constraints*.
