Title: Fix treemap overhang problem.

This also fixes #136 so I've removed the now redundant check for non-zero v if the flush flag is set.

The overhanging rectangles seem more likely to occur when rounding is turned on, because positions sometimes get rounded up and overflow the allowed range that is currently being filled.
