I don't think I have the foggiest idea of how one would go about doing  
that, meaning where the above would fit into the scheme of things in  
imnoise, and how to make a patch.
I would if I could...but I think it would take me too long to figure out  
what I had to do.
When I have some time and inclination, I will see if I can understand how  
the above code snippet should fit into imnoise, and how to make a patch.
One of the problems is that by the time I get around it, I'll probably  
have forgotten :-)
