That's what I'm trying to do but I'm unsuccessful yet.
I'll tell you when I'll have found something.

By the way I remember something strange: when rendering with current 
CVS, it seems that for each tile of the image, there are two renders. I 
see a first pass that is darker than the final image and then a new pass 
that build the final image. What are those two passes?
