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 "halign" and "valign" properties.
For baseline support in containers you need to use gtk_widget_size_allocate_with_baseline()
instead.
