   \class vtkOrientedBoxWidget
   \brief orthogonal hexahedron 3D widget with pre-defined orientation

   Description

   This 3D widget defines a region of interest. By default it behaves exactly as the
   vtkBoxWidget class does. But if the user set the Orientation matrix with
   SetOrientationMatrix() then all the actors of the widgets (handles, hexahedron, etc)
   will be oriented according to the argument.
