Hooks up an adjustment to focus handling in a container, so when a child
of the container is focused, the adjustment is scrolled to show that
widget. This function sets the horizontal alignment.
See gtk_scrolled_window_get_hadjustment() for a typical way of obtaining
the adjustment and gtk_container_set_focus_vadjustment() for setting
the vertical adjustment.
The adjustments have to be in pixel units and in the same coordinate
system as the allocation for immediate children of the container.
