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.
