20 If clue is 0, then the aspect ratio for the requested mode ( x:y ) must
21 be 4:3. A mode with the same aspect ratio closest to the requested,
22 while still having a higher resolution is found, and then scaled down
23 to the requested mode.

25 If clue is 1, then the aspect ratio for the requested mode ( x:y ) must
26 be 4:3. A mode with the same aspect ratio closest to the requested,
