/**
* Let SDL handle dbus_shutdown().
* Cause SDL to call dbus_shutdown() on quit.
*
* Only enable this option if no other dependency uses D-Bus.
* This is useful as a debug tool to validate memory leaks, but shouldn't ever
* be set in production applications, as other libraries used by the application
* might use dbus under the hood and this cause cause crashes if they continue
* after SDL_Quit().
*
* This option tells SDL that it can safely call dbus_shutdown() when
* SDL_Quit() is called. You must ensure that no other library still uses
* D-Bus when SDL_Quit() is called, otherwise resources will be freed while
* they are still in use, which results in undefined behavior and likely a
* crash.
* This variable can be set to the following values:
* "0" - SDL will not call dbus_shutdown() on quit (default)
* "1" - SDL will call dbus_shutdown() on quit
*
* Use this option to prevent memory leaks if your application doesn't use
* D-Bus other than through SDL.
* This hint is available since SDL 2.30.0.
