Convert an initial size allocation assigned
by a #GtkContainer using gtk.widget.Widget.sizeAllocate, into an actual
size allocation to be used by the widget. adjust_size_allocation
adjusts to a child widget’s actual allocation
from what a parent container computed for the
child. The adjusted allocation must be entirely within the original
allocation. In any custom implementation, chain up to the default
#GtkWidget implementation of this method, which applies the margin
and alignment properties of #GtkWidget. Chain up
before performing your own adjustments so your
own adjustments remove more allocation after the #GtkWidget base
class has already removed margin and alignment. The natural size
passed in should be adjusted in the same way as the allocated size,
which allows adjustments to perform alignments or other changes
based on natural size.
