//! Quit stuff.
//!
//! An [`SDL_QUIT`] event 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_QUIT`] events as well.  There is no way to determine the
//! cause of an [`SDL_QUIT`] event, but setting a signal handler in your
//! application will override the default generation of quit events for that
//! signal.
