Subject: [PATCH] On LetterBox make a Pillarbox if aspect ratio is equal

If background video and Vocaluxe have the same aspect ratio, switching to aspect ratio LetterBox would do a Pillarbox, so you can add 4:3 borders, if a video file has the wrong aspect ratio (maybe SAR value at 16:9, but a DAR value at 4:3). Without this change, LetterBox would do exactly the same as Crop in this special case.
