/**
* @class vtkSplineRepresentation
* @brief representation for a spline.
*
* vtkSplineRepresentation is a vtkWidgetRepresentation for a spline.
* This 3D widget defines a spline that can be interactively placed in a
* scene. The spline has handles, the number of which can be changed, plus it
* can be picked on the spline itself to translate or rotate it in the scene.
* This is based on vtkSplineWidget.
