Summary: So far whenever the window geometry changed the widthChanged and heightChanged signals were emitted even if they did not change. E.g. while moving a window this resulted in the signal being emitted after every step, although from decoration point of view nothing changed. The decoration performed costly tasks like re-layout the window buttons. With this change the client size is cached and the widthChanged signal is only emitted if the width actually changed. Same for heightChanged. This results in the decoration only re-layouting the buttons if the window is resized horizontally. All other geometry changes no longer result in a re-layout.
