// .NAME vtkCarbonRenderWindowInteractor - implements Carbon specific functions
// required by vtkRenderWindowInteractor.
//
// .SECTION Description
// The interactor interfaces with vtkCarbonWindow to trap messages from the
// Carbon window manager and send them to vtk. Since OS X applications
// typically use the Command key where UNIX and Windows applications would use
// the Ctrl key, this interactor maps the Command key to Ctrl. In versions of
// VTK prior to VTK 6.2, it was mapped to Alt. On OS X, the Option key can be
// used as Alt.

// Enable/Disable interactions. By default interactors are enabled when
// initialized. Initialize() must be called prior to enabling/disabling
// interaction. These methods are used when a window/widget is being
// shared by multiple renderers and interactors. This allows a "modal"
// display where one interactor is active when its data is to be displayed
// and all other interactors associated with the widget are disabled
// when their data is not displayed.
