// .NAME QVTKApplication - A superclass for QApplication using VTK.
// .SECTION Description
// This is a superclass for QApplication using VTK. It essentially redefined
// x11EventFilter() in order to catch X11 ClientMessage coming from the
// 3DConnexion driver.
//
// You don't have to inherit from QVTKApplication to be able to use VTK:
// you can reimplement QVTKApplication(), ~QVTKApplication(), x11EventFilter(),
// setDevice(), CreateDevice() in your own subclass of QApplication.
// It you don't, VTK will work but without the 3Dconnexion device under X11.
// In this case, QVTKApplication provides a model of implementation.
