/**
 * pqLightPropertyWidget is a custom property widget that uses
 * "LightWidgetRepresentation" to help users interactively set a light properties in
 * space. To use this widget for a property group
 * (vtkSMPropertyGroup), use "InteractiveLight" as the "panel_widget" in the
 * XML configuration for the proxy. The property group should have properties for
 * following functions:
 * \li \c Positional: a 1-tuple vtkSMIntVectorProperty with a vtkSMEnumerationDomain
 * that will be use to show the positional cone or not.
 * \li \c WorldPosition: a 3-tuple vtkSMDoubleVectorProperty that will be linked to the
 * origin of the interactive light.
 * \li \c FocalPoint: a 3-tuple vtkSMDoubleVectorProperty that will be linked to the
 * the focal point of the interactive light.
 * \li \c FocalPoint: a 1-tuple vtkSMDoubleVectorProperty with a vtkSMDoubleRangeDomain
 * that will be linked to the cone angle of the interactive light.
