UndoRedo Command created even when no changes are made
In my application I start an undo/redo action (UndoRedoArea.Start) when the user grabs a figure (left mouse button), and commit it (UndoRedoArea.Commit) when they let go. If the user does not change the properties of the figure (eg. by dragging it) the
commit still creates an undo/redo action. It would be nice if no undo/redo action was created if no changes were made.
