Even if it needed to be rewritten quite a bit, the way you did it to handle ratios less than one (or non-integer greater-than-one ratios) smoothly might be a good example to follow for anyone interested. At the least, that might lead to reasonably consistent usage and end-user experience between the existing implementation and any new one for Xorg. This message posted from opensolaris.org
