  An SDL_QUITEVENT is generated when the user tries to close the application
slouken@0
    35
  window.  If it is ignored or filtered out, the window will remain open.
slouken@0
    36
  If it is not ignored or filtered, it is queued normally and the window
slouken@0
    37
  is allowed to close.  When the window is closed, screen updates will 
slouken@0
    38
  complete, but have no effect.

  SDL_Init() installs signal handlers for SIGINT (keyboard interrupt)
slouken@0
    41
  and SIGTERM (system termination request), if handlers do not already
slouken@0
    42
  exist, that generate SDL_QUITEVENT events as well.  There is no way
slouken@0
    43
  to determine the cause of an SDL_QUITEVENT, but setting a signal
slouken@0
    44
  handler in your application will override the default generation of
slouken@0
    45
  quit events for that signal.
