// .NAME vtkDistanceRepresentation2D - represent the vtkDistanceWidget
// .SECTION Description
// The vtkDistanceRepresentation2D is a representation for the
// vtkDistanceWidget. This representation consists of a measuring line (axis)
// and two vtkHandleWidgets to place the end points of the line. Note that
// this particular widget draws its representation in the overlay plane.
