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.
