/**
 * pqCoordinateFramePropertyWidget is a custom property widget that uses
 * "CoordinateFrameWidgetRepresentation" to help users interactively set the origin
 * and normal for a plane. To use this widget for a property group
 * (vtkSMPropertyGroup), use "InteractiveFrame" as the "panel_widget" in the
 * XML configuration for the proxy. The property group should have properties for
 * following functions:
 * \li \c Origin: a 3-tuple vtkSMDoubleVectorProperty that will be linked to the
 *        origin of the interactive coordinate frame.
 * \li \c XAxis: a 3-tuple vtkSMDoubleVectorProperty that will be linked to the
 *        x axis for the interactive coordinate frame.
 * \li \c YAxis: a 3-tuple vtkSMDoubleVectorProperty that will be linked to the
 *        y axis for the interactive coordinate frame.
 * \li \c ZAxis: a 3-tuple vtkSMDoubleVectorProperty that will be linked to the
 *        z axis for the interactive coordinate frame.
 * \li \c Input: (optional) a vtkSMInputProperty that is used to get data
 *        information for bounds when placing/resetting the widget.
