* Initialize the video subsystem, optionally specifying a video driver.
*
* This function initializes the video subsystem, setting up a connection to
* the window manager, etc, and determines the available display modes and
* pixel formats, but does not initialize a window or graphics mode.
*
* If you use this function and you haven't used the SDL_INIT_VIDEO flag with
* either SDL_Init() or SDL_InitSubSystem(), you should call SDL_VideoQuit()
* before calling SDL_Quit().
*
* It is safe to call this function multiple times. SDL_VideoInit() will call
* SDL_VideoQuit() itself if the video subsystem has already been initialized.
*
* You can use SDL_GetNumVideoDrivers() and SDL_GetVideoDriver() to find a
* specific `driver_name`.
*
* \param driver_name the name of a video driver to initialize, or NULL for
* the default driver
* \returns 0 on success or a negative error code on failure; call
* SDL_GetError() for more information.
