This function is only used by gtk.widget.Widget subclasses, to
assign a size, position and (optionally) baseline to their
child widgets.
In this function, the allocation and baseline may be adjusted.
The given allocation will be forced to be bigger than the
widget's minimum size, as well as at least 0×0 in size.
