A live rectangle, rounded rectangle, ellipse or polygon selected with the
Selection tool shows a Shape Properties button where Lock was. It opens a
popup with the shape's rows from the Transform panel, which stays open
while the fields are edited. Every other selection, and the Direct and
Group Selection tools, keep Lock; Object > Lock and Cmd+2 still lock a
shape.
The Transform panel, the Properties panel and the popup draw the rows
through one live_shape_rows function.
