vtkRenderWindowInteractor - handle render window interaction including picking and frame rate control. ### Description vtkRenderWindowInteractor provides an interaction mechanism for mouse/key/time events. It handles routing of mouse/key/timer messages to vtkInteractorObserver and its subclasses. vtkRenderWindowInteractor also provides controls for picking, rendering frame rate. vtkRenderWindowInteractor serves to hold user preferences and route messages to vtkInteractorStyle. Callbacks are available for many events. Platform specific subclasses should provide methods for manipulating timers, TerminateApp, and an event loop if required via Initialize/Start/Enable/Disable. ### Caveats vtkRenderWindowInteractor routes events through VTK's command/observer design pattern. That is, when vtkRenderWindowInteractor (actually, one of its subclasses) sees an event, it translates it into a VTK event using the InvokeEvent() method. Afterward, any vtkInteractorObservers registered for that event are expected to respond appropriately.
