Come to think of it, it would be nice if we could use such generators as input 
for masks, too. That's a bit harder with the current structure, more 2.1 
stuff. The noise layer type thing is something that could easily be done for 
2.0.

Right now, nodes either take their parent (if they are masks) or the layer 
stack underneath them (if adjustment layer) or their (children) as input -- 
or a plain paint device with user-supplied content, such as an image from 
disk (but the content is not linked to that file, it's copied) or their own 
sketches. Fixing that limitation demands a little bit of thinking and a lot 
of work, particularly in the user interface.
