 * @brief   vtkWidgetRepresentation for a poly line.
 *
 * vtkPolyLineRepresentation is a vtkCurveRepresentation for a poly
 * line. This 3D widget defines a poly line that can be interactively
 * placed in a scene. The poly line has handles, the number of which
 * can be changed, plus the widget can be picked on the poly line
 * itself to translate or rotate it in the scene.
 * Based on vtkCurveRepresentation
 * @sa
 * vtkSplineRepresentation
