// .NAME vtkCompositeRepresentation - combine multiple representations into one
// with only 1 representation active at a time.
// .SECTION Description
// vtkCompositeRepresentation makes is possible to combine multiple
// representations into one. Only one representation can be active at a give
// time. vtkCompositeRepresentation provides API to add the representations that
// form the composite and to pick the active representation.
//
// vtkCompositeRepresentation relies on call AddToView and RemoveFromView
// on the internal representations whenever it needs to change the active
// representation. So it is essential that representations handle those methods
// correctly and don't suffer from uncanny side effects when that's done
// repeatedly.
