vga_guesstiming \- calculate a timing line for the given resolution
.SH SYNOPSIS

.B "#include <vga.h>"

.BI "int vga_guesstiming(int x, int y, int clue, int arg);

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

.SH CALCULATION METHODS
If 
.BR clue
is 0, then the aspect ratio for the requested mode (
.BR 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 
.BR clue
is 1, then the aspect ratio for the requested mode (
.BR 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.

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