Well, I did some tests walking the tree and printing out all line type 2 as cylinders,
but I didn't think it looked to well.
Mostly because at some edges you only see 1/4 of the cylinder,
and at other edges you see 3/4 of the cylinder.
L3P doesn't walk the tree (yet), but I could add an option to L3Lab
to export a "POV cylinder file" that you could include in the L3P POV file.
It could even have support for line type 5 since the camera location is
in the POV file...
