Thank you indeed! Very useful. Noting it does exactly the opposite of 
what I generally do :-) For ages I have been using Norbert Kern's 
position_finder.pov macro from 2006, to get (with variable precision I 
must confess) a position somewhere on a 3D landscape or object, 
calculated from a 2D render of the scene. I then use the found 3D 
coordinates to place new objects in the scene.
