 * @class   vtkTDxInteractorStyle
 * @brief   provide 3DConnexion device event-driven interface to the rendering window
 *
 *
 * vtkTDxInteractorStyle is an abstract class defining an event-driven
 * interface to support 3DConnexion device events send by
 * vtkRenderWindowInteractor.
 * vtkRenderWindowInteractor forwards events in a platform independent form to
 * vtkInteractorStyle which can then delegate some processing to
 * vtkTDxInteractorStyle.
