This might be a stupid question, but would it not make more sense to
teach doc-view to generate images that are the correct resolution
already? That would make it look much better than any scaling option.
This will involve many tricks to be added, doc-view uses image-mode to view the image, and user can change (enlarge) window size at any moment, so doc-view must add some handlings for that to regenerate/redisplay images. Also using larger images makes things slower, then just applying scale filter at display time.
