/*
I'm trying to make the rear lights symetrical in a car I'm modelling in Pov 3.5
Beta 2.
Does anyone know why it's asymetrical?
Any help will be appreciated.

these last two items don't seem to be symmetrical in their dimensions
PS
Why not just create the right hand light and create the left one by scaling
the right by <-1,1,1>?

Duh! Why didn't I think of that in the first place...
