properties dialog should have a button to undo all changes made while interacting with the dialog

Description
The properties dialog has three buttons: "Close", "Apply", "OK". The action represented by "OK" actually implies "Apply" followed by "Close". It would be nice if the dialog box instead had three buttons: "Cancel", "Apply" and "OK". Pressing "Cancel" always undoes all changes made by this dialog. Pressing "Apply" always sets any modified properties. Pressing "OK" sets any outstanding properties not already handled by "Apply", and then closes the dialog.
