// .NAME vtkScalarBarRepresentation - represent scalar bar for vtkScalarBarWidget
//
// .SECTION Description
//
// This class represents a scalar bar for a vtkScalarBarWidget. This class
// provides support for interactively placing a scalar bar on the 2D overlay
// plane. The scalar bar is defined by an instance of vtkScalarBarActor.
//
// One specialty of this class is that if the scalar bar is moved near enough
// to an edge, it's orientation is flipped to match that edge.
//
// .SECTION See Also
// vtkScalarBarWidget vtkWidgetRepresentation vtkScalarBarActor
