[print] Don't use negative overflow for scaling.

Within ForceLayoutForPagination we used the LayoutOverflow on a
fragment to determine the total scale factor. This looked correct
however if we had negative overflow - we'd consider that in the
total width causing a large scale factor.

Instead of using Width()/Height(), use Right()/Bottom() (considering
only the "positive" overflow) for determining the total scale factor.
