GtkAlignment is a container class that controls
the alignment and scale of its child widget, relative to its own
dimensions.
Where the child widget has sizing responsibilites to a child or children
of its own, these are fulfilled as a priority. For example, a
GtkButton with a label will never be scaled down
to the minimal size that the same widget with no label can; the label
is the button's child, and the button must honour its size request.
