Seth Hillbrand ba73456d49 Allow point editor to persist 
After drawing a graphic, allow the control points to persist when
exiting the tool.

The effect of this is to make the first "Esc" press a
"return-to-select-tool" event without modifying the selection or control
points from within the drawing tools.  The section "Esc" press, when in
the selection tool will clear the selection and the control points
