        Unlike in Mac OS X, it appears there is no way to cancel the termination.
     
        This doesn't give the SDL user's application time to respond to an SDL_Quit event.
        So what we do is that in the UIApplicationDelegate class (SDLUIApplicationDelegate),
        when the delegate receives the ApplicationWillTerminate message, we execute
        a longjmp statement to get back here, preventing an immediate exit.
