SDL_SetRenderVSync - Toggle VSync of the given renderer.

       This function is available since SDL 3.2.0.

       When a renderer is created, vsync defaults to SDL_RENDERER_VSYNC_DISABLED.

       The vsync parameter can be 1 to synchronize present with every vertical refresh, 2 to synchronize present
       with  every  second  vertical  refresh, etc., SDL_RENDERER_VSYNC_ADAPTIVE for late swap tearing (adaptive
       vsync), or SDL_RENDERER_VSYNC_DISABLED to disable. Not every value is supported by every driver,  so  you
       should check the return value to see whether the requested setting is supported.
