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