Added an indicator telling whether a widget prefers to be allocated as height-for-width or width-for-height. Usually this depends on the orientation of a container or the nature of a content widget like GtkLabel. This indicator is only used in the seldom case where a parent is allocating free space to the child and the child can flow in either direction, GtkWindow and GtkScrolledWindow are users of this api.
