[cbpbejjn] Lossless crop

JPEG, because it works on 8x8 blocks, has the ability to do lossless crop (so long as you are cropping on a block boundary).  Newer lossy image compression algorithms which process the whole image at once lose this ability.  Perhaps this feature can be recovered if such newer algorithms could also encode "don't care" values in cropped areas.
