If you want the device to do nothing if the window is inactive
(recommended), use the slightly enhanced code shown at isWindowActive().
Note if you are running Irrlicht inside an external, custom
created window: Calling Device->run() will cause Irrlicht to
dispatch windows messages internally.
If you are running Irrlicht in your own custom window, you can
also simply use your own message loop using GetMessage,
DispatchMessage and whatever and simply don't use this method.
But note that Irrlicht will not be able to fetch user input
then. See irr::SIrrlichtCreationParameters::WindowId for more
informations and example code.
