    34  *  An SDL_QUITEVENT is generated when the user tries to close the application

    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.

    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.
