* points of a line. To use this widget for a property group
* (vtkSMPropertyGroup), use "InteractiveLine" as the "panel_widget" in the
* XML configuration for the proxy. The property group should have properties for
* following functions:
* \li \c Point1WorldPosition: a 3-tuple vtkSMDoubleVectorProperty that will be
* linked to one of the end points of the line.
* \li \c Point2WorldPosition: a 3-tuple vtkSMDoubleVectorProperty that will be
* linked to the other end point of the line.
* \li \c Input: (optional) a vtkSMInputProperty that is used to get data
* information for bounds when placing/resetting the widget.
