Hello,
 how do I make an image_map (or even any pigment) brighter or darker?
I could average it with black but that is not that nice and it can only
darken the picture (unless you can use negative weights).
 Also, how do I create a pigment which is a sum of red gradient x, green
gradient y and blue gradient z, so that the pigment color describes its
position in space?
the best I could do is to average those three gradients but I look for a
cleaner way.
 Thanks in advance,
Honnza
