/**

* # CategoryQuit

* 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.
