/**
* @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.
