This function is only used by #GtkContainer subclasses, to assign a size
and position to their child widgets.
In this function, the allocation may be adjusted. It will be forced
to a 1x1 minimum size, and the adjust_size_allocation virtual
method on the child will be used to adjust the allocation. Standard
adjustments include removing the widget’s margins, and applying the
widget’s #GtkWidget:halign and #GtkWidget:valign properties.
For baseline support in containers you need to use gtk_widget_size_allocate_with_baseline()
instead.
