    33 /* 
    34   An SDL_QUITEVENT is generated when the user tries to close the application
    35   window.  If it is ignored or filtered out, the window will remain open.
    36   If it is not ignored or filtered, it is queued normally and the window
    37   is allowed to close.  When the window is closed, screen updates will 
    38   complete, but have no effect.
    39 
    40   SDL_Init() installs signal handlers for SIGINT (keyboard interrupt)
    41   and SIGTERM (system termination request), if handlers do not already
    42   exist, that generate SDL_QUITEVENT events as well.  There is no way
    43   to determine the cause of an SDL_QUITEVENT, but setting a signal
    44   handler in your application will override the default generation of
    45   quit events for that signal.
