NAME
       vga_guesstiming - calculate a timing line for the given resolution

SYNOPSIS
       #include <vga.h>

       int vga_guesstiming(int x, int y, int clue, int arg);

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

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

       If clue is 1, then the aspect ratio for the requested mode ( x:y ) must
       be 4:3. A mode with the same aspect ratio closest to the requested,
       while still having a lower resolution is found, and then scaled down to
       the requested mode.

BUGS
       No guarantee that a modeline will be created, or that a created
       modeline will be usefull is given.
