I would strongly recommend you get yourself a book on ray-tracing if you 
want to know why POV-Ray does things the way it does them. The source code 
is pretty much the wrong place to start to learn how ray-tracing works. 
There are several books listed in the documentation, several of which will 
be readily available in your local library.
