DESCRIPTION

15       Calculates  a  timing line for a x*y resolution, according to the value
16       of clue.

CALCULATION METHODS

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.
24
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,
27       while still having a lower resolution is found, and then scaled down to
28       the requested mode.

BUGS

32       No guarantee that a modeline will be created, or that a  created  mode‐
33       line will be usefull is given.
