Is this really needed?

Yes, I'm afraid so. Omitting these lines will result in faulty output,
so is any combination of the original and the modified parameters. In
fact the only combination to produce any image (apart from the one in
the patch) is crop_w/crop_/h and outlink->w/outlink->h but even that's
faulty.
