30 * Initialize the video subsystem, optionally specifying a video driver.
31 *
32 * This function initializes the video subsystem, setting up a connection to
33 * the window manager, etc, and determines the available display modes and
34 * pixel formats, but does not initialize a window or graphics mode.
35 *
36 * If you use this function and you haven't used the SDL_INIT_VIDEO flag with
37 * either SDL_Init() or SDL_InitSubSystem(), you should call SDL_VideoQuit()
38 * before calling SDL_Quit().
39 *
40 * It is safe to call this function multiple times. SDL_VideoInit() will call
41 * SDL_VideoQuit() itself if the video subsystem has already been initialized.
42 *
43 * You can use SDL_GetNumVideoDrivers() and SDL_GetVideoDriver() to find a
44 * specific `driver_name`.
45 *
46 * \param driver_name the name of a video driver to initialize, or NULL for
47 *                    the default driver
48 * \returns true on success or false on failure; call
49 *          SDL_GetError() for more information.
