the @constructed function is called by gobject.object.ObjectG.new_ as the
final step of the object creation process. At the point of the call, all
construction properties have been set on the object. The purpose of this
call is to allow for object initialisation steps that can only be performed
after construction properties have been set. @constructed implementors
should chain up to the @constructed call of their parent class to allow it
to complete its initialisation.
