//       Class : LPoint3
// Description : This is a three-component point in space (as opposed
//               to a three-component vector, which represents a
//               direction and a distance).  Some of the methods are
//               slightly different between LPoint3 and LVector3; in
//               particular, subtraction of two points yields a
//               vector, while addition of a vector and a point yields
//               a point.
