If the constant is not signed, it can be interesting.
Or maybe with some custom pixel types, operator-() can have a  
different behavior.

Anyway, those features have been merged in AddImageFilter and  
SubtractImageFilter, which are both needed to work with two images, so  
the question is less relevant now :-)
