Sure, it's moot for rendering a square image, but only because min==max for that case. It's what the behavior should be when they're not the same -- which is a common case going to file and to framebuffer (in mged/archer or otherwise). Leaving it at the diagonal isn't "wrong" but will result in some geometry getting clipped if the view aspect is sufficiently different from the bounding box aspect. Since the diagonal is arguably sufficient, that's why my suggestion was to first just add the scaling factor parameter. It's a safe non-behavior changing addition that would give the rt* apps and mged a means to retain current behavior if we make the default be something else. Cheers!
