+  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.
