   Just tried it for noise:

   tonemapping {
     parameters { red,green,blue }
     function(r,g,b) { r*f_granite(g*image_width,b*image_height,0) }
     function(r,g,b) { g*f_granite(r*image_width,b*image_height,0) }
     function(r,g,b) { b*f_granite(r*image_width,g*image_height,0) }
   }

   I don't know if I've used it correctly there, but looks nice without
aa. With aa it loses most of the noise (and a later conversion to jpg
makes it almost unnoticeable). I guess that's one of the things that
will do better with the future post-aliasing "postprocesing" feature.
