It's using several different methods, depending on what kind of picking 
you are doing.  One uses a picking buffer (that yes, would probably 
break on non-32-bit), the other uses a traced ray collision.

My camera patch really cleans up this traced ray collision code so that 
it's accurate, it's being munged all the hell right now in the name of 
second guessing where the user meant to click.
