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