// The application state events and following methods: IrrlichtDevice::isWindowActive, IrrlichtDevice::isWindowFocused
// and IrrlichtDevice::isWindowMinimized works out of box only if you'll use built-in CIrrDelegateiOS,
// so _IRR_COMPILE_WITH_IOS_BUILTIN_MAIN_ must be enabled in this case. If you need a custom UIApplicationDelegate you must
// handle all application events yourself.
