Hmm this is quite long,

1) hierarchy is ofcourse *on* as default ?

2) bouning boxes do work? maybe set bounding_threshold to 1 to enforce 
using them


Btw, I do have few ideas about speeding up renderings of most POV 
objects... I hope I'll have time to implement them and they will prove 
usefull :)

One of simplest of thoes ideas - triangulize Your object (trace lots of 
points, then connect them into smooth mesh). It would be nice if POV could
a) done this automaticly
b) ...with calculating normals
c) ...with handling non-continous objects (with holes in them, or with 
totaly not-connected to each other parts)
