    1.37 +  An SDL_QUITEVENT is generated when the user tries to close the application
    1.38 +  window.  If it is ignored or filtered out, the window will remain open.
    1.39 +  If it is not ignored or filtered, it is queued normally and the window
    1.40 +  is allowed to close.  When the window is closed, screen updates will 
    1.41 +  complete, but have no effect.
    1.42 +
    1.43 +  SDL_Init() installs signal handlers for SIGINT (keyboard interrupt)
    1.44 +  and SIGTERM (system termination request), if handlers do not already
    1.45 +  exist, that generate SDL_QUITEVENT events as well.  There is no way
    1.46 +  to determine the cause of an SDL_QUITEVENT, but setting a signal
    1.47 +  handler in your application will override the default generation of
    1.48 +  quit events for that signal.
