Creates a new #GtkIconFactory. An icon factory manages a collection
of #GtkIconSets; a #GtkIconSet manages a set of variants of a
particular icon (i.e. a #GtkIconSet contains variants for different
sizes and widget states). Icons in an icon factory are named by a
stock ID, which is a simple string identifying the icon. Each
#GtkStyle has a list of #GtkIconFactorys derived from the current
theme; those icon factories are consulted first when searching for
an icon. If the theme doesn’t set a particular icon, GTK+ looks for
the icon in a list of default icon factories, maintained by
gtk.icon_factory.IconFactory.addDefault and
gtk.icon_factory.IconFactory.removeDefault. Applications with icons should
add a default icon factory with their icons, which will allow
themes to override the icons for the application.
