Still, what *is* the location? A sphere has a center, but what is the 
center of a cone? The middle of the bounding box? The center of gravity?
What is the "location" of an infinite plane? A complex mesh or CSG?
Each object should have it's own variables available, but a single 
"location" variable for all of them isn't possible. Maybe a 
GetLocation() method for all objects in the finite object portion of the 
heirarchy, but you still have to define the location of an arbitrary 
object.
