/**
* pqSplinePropertyWidget is a custom property widget that uses
* "SplineWidgetRepresentation" to help users interactively set points that
* form a spline. To use this widget for a property group (vtkSMPropertyGroup),
* use "InteractiveSpline" as the "panel_widget" in the XML configuration.
* The property group can have properties for following functions:
* \li \c HandlePositions: a repeatable 3-tuple vtkSMDoubleVectorProperty that
* corresponds to the property used to set the selected spline points.
* \li \c Closed: (optional) a 1-tuple vtkSMIntVectorProperty that
* corresponds to the boolean flag indicating if the spline should be closed at end points.
* \li \c Input: (optional) a vtkSMInputProperty that is used to get data
* information for bounds when placing/resetting the widget.
* This widget can also be used for a poly-line instead of a spline. For this mode, use
* "InteractivePolyLine" as the "panel_widget" in the XML configuration.
