// .NAME vtkPVInteractorStyleControl - a control widget for manipulators
// .SECTION Description
// This widget defines a user interface for controling interactor
// style. It defines nine menus for different button and keyboard
// combinations and bind a manipulator for each one of them. It also
// provides a simple user interface for some manipulators.
