// .NAME vtkWin32RenderWindowInteractor - implements Win32 specific functions
// required by vtkRenderWindowInteractor.
//
// .SECTION Description
// By default the interactor installs a MessageProc callback which
// intercepts windows' messages to the window and controls interactions by
// routing them to the InteractoStyle classes.
// MFC or BCB programs can prevent this and instead directly route any mouse/key
// messages into the event bindings by setting InstallMessageProc to false.
// This provides a minimal "Mapped" mode of interaction
