- 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.
