Comment (by ubitux):

 Representation for optional combinations implemented (that was painful...
 code a bit ugly). So now, we have:

 - red:   must have a diff with center pixel
 - gray:  must not have a diff with center pixel
 - black: whether there is a diff or not doesn't matter

 I hope I didn't get it wrong. I think I'll try to implement from this,
 unless I see a way of improving even more the representation.

 (Note: the wrong colors for the coeff intensity are also fixed)
