* This class is a vtkPlotRangeHandlesItem specialization working in

* coordination with a vtkPlotBar. It ensures that handles are sticking to the

|
|
* plot bars when being dragged.
|
||
|
|
* Vertical and horizontal bars are both supported but the handles orientation
|
||
|
|
* must match the vtkPlotBar orientation.
