A correction, or rather an omission, something I forgt: there was 
somebody who more recently came up with a clever way to duplicate the 
find_edges feature using functions and the slope pattern. He basically 
got the necessary color, normal, and depth information encoded in RGB 
image files, and used those files as input to the algorithm. It required 
several renderings of the scene (to generate the necessary data files), 
and of course the data was a bit limited in accuracy, but it worked and 
was implemented entirely in POV script. He posted his work to one of the 
scene file groups on this server, search for "find_edges".
