/** Also increments the virtual timer by calling

ITimer::tick();. You can prevent this

calling IrrlichtDevice::run(). Returns false if device wants

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
64
dispatch windows messages internally.
65
If you are running Irrlicht in your own custom window, you can
66
also simply use your own message loop using GetMessage,
67
DispatchMessage and whatever and simply don't use this method.

But note that Irrlicht will not be able to fetch user input
69
then. See irr::SIrrlichtCreationParameters::WindowId for more

informations and example code.
