That's basically what a bumpmap filter in Krita or Gimp does, isn't it? Take a 
layer (or mask, both are nodes) and use it to determine modifications in 
another layer or mask. I think I already finished porting the bumpmap filter 
this summer, so there's an example ready for anyone who wants to implement 
such a filter.
