Well, you may not, but others do.

The current mechanism is fine as long as the person running the render
is fully aware of the aspect ratio the scene was designed for, or the
final resolution is explicitly specified in an INI file.

The mechanism has its shortcomings however, if the person running the
render is unaware of the intended aspect ratio, and the original author
did not fix the resolution via an INI file.


In an ideal world, I think we would have a means to specify the aspect
ratio in the scene file, and specify only the horizontal or vertical
resolution via INI or command-line parameters, and have the other
dimension computed automatically.
