ANN: Dragging along a fixed path

[Jim Hurley]

The stack below allows one to drag a control along a constrained 
path, e.g. a graphic or image along a closed polygon path--see cards 
2 and 3. (The polygon may not have any obtuse angles--angles greater 
than 180 degrees.)

(Of course one can easily program the control to move along a 
graphic: "Move button "My Button" to the points of graphic "My 
Curve".)
