The sheet was stretched over the visitor's frame, so the portrait variant
only turned the paper inside whatever shape the photo had: a landscape
photo stayed landscape. The film now has its own opening like the walls
do — the frame is scaled up to the photo, the photo is cover-cropped into
the whole sheet, and `old-film-portrait` is the PNG turned 90° CW, so the
pair is one frame standing and one lying. The torn edge has no straight
sides, so the photo runs under all of it instead of being cut against a
measured window.
