These are here to make sure SDL + * does not even attempt to touch low-level pieces of the operating system + * that you don't intend to use. For example, you might be using SDL for video + * and input but chose an external library for audio, and in this case you + * would just need to leave off the `SDL_INIT_AUDIO` flag to make sure that + * external library has complete control. + * + * Most apps, when terminating, should call SDL_Quit(). This will clean up + * (nearly) everything that SDL might have allocated, and crucially, it'll + * make sure that the display's resolution is back to what the user expects if + * you had previously changed it for your game. + * + * SDL3 apps are strongly encouraged to call SDL_SetAppMetadata() at startup + * to fill in details about the program. This is completely optional, but it + * helps in small ways (we can provide an About dialog box for the macOS menu, + * we can name the app in the system's audio mixer, etc).
