2551SelectionTweaks-di -- Dan Ingalls -- 31 August 2000 Fixes a bug that caused shift-drag of polygon vertices to grow the vertex handles. Limits group selection to the submorphs of the pasteup in which the selection was begun. Allows a group selection to be augmented or depleted by secondary selections. Elides close curve options for lines with only two vertices.

Selection rectangle does not delete it self.
