public class SelectionResize
extends Selection

A Selection class to represent selections on Figs that present resize handles. The selected Fig can be moved or resized. Figrect, FigRRect, FigCircle, and FigGroup are some of the Figs that normally use this Selection. The selected Fig is told it's new bounding box, and some Figs (like FigGroup or FigPoly) do calculations to scale themselves.
