SDL_GetClosestFullscreenDisplayMode - Get the closest match to the requested display mode.

       This function is available since SDL 3.2.0.

       The  available  display  modes  are  scanned  and closest is filled in with the closest mode matching the
       requested mode and returned. The mode format and refresh rate default to the desktop mode if they are set
       to 0. The modes are scanned with size being first priority, format being  second  priority,  and  finally
       checking the refresh rate. If all the available modes are too small, then false is returned.

       w      the width in pixels of the desired display mode.
