 * @class   vtkWorldPointPicker
 * @brief   find world x,y,z corresponding to display x,y,z
 *
 * vtkWorldPointPicker is used to find the x,y,z world coordinate of a
 * screen x,y,z. This picker cannot pick actors and/or mappers, it
 * simply determines an x-y-z coordinate in world space. (It will always
 * return a x-y-z, even if the selection point is not over a prop/actor.)
 *
 * @warning
 * The PickMethod() is not invoked, but StartPickMethod() and EndPickMethod()
 * are.
