The #GtkAdjustment object represents a value which has an associated lower
and upper bound, together with step and page increments, and a page size.
It is used within several GTK+ widgets, including #GtkSpinButton, #GtkViewport,
and #GtkRange (which is a base class for #GtkScrollbar and #GtkScale).
The #GtkAdjustment object does not update the value itself. Instead
it is left up to the owner of the #GtkAdjustment to control the value.
