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.
Implemented in editor::editor_action_paste, editor::editor_action_area, editor::editor_action_deselect, and editor::editor_action_select.
