The crux of the extendable contract.
This member function must be implemented so that the undo behavior is consistent, exactly the same as would be with separate undo actions for every part of the drag.

Perform the action, returning an undo action that, when performed, shall reverse any effects of this action.
The undo action object is owned by the caller. Default behavior is to create a whole-map undo, call the perform_without_undo function and return the undo object.
