Setting width or height (horizontal or vertical) to an arbitrary value
causes the wibox not to be stretched. Instead the align() function is
called, which might not modify any wibox property in many situations,
or none when align parameter was not provided by the user. The major
side effect is that wibox struts were never updated and clients
covered the wibox (until a first signal handler caused struts to be
updated).
