Remarks
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 NULL is returned.
