 /**
  * SECTION:gtkmisc
  * @Short_description: Base class for widgets with alignments and padding
  * @Title: GtkMisc
  *
  * The #GtkMisc widget is an abstract widget which is not useful itself, but
  * is used to derive subclasses which have alignment and padding attributes.
  *
  * The horizontal and vertical padding attributes allows extra space to be
  * added around the widget.
  *
  * The horizontal and vertical alignment attributes enable the widget to be
  * positioned within its allocated area. Note that if the widget is added to
  * a container in such a way that it expands automatically to fill its
  * allocated area, the alignment settings will not alter the widgets position.
  *
  * <note>
  * Note that the desired effect can in most cases be achieved by using the
  * #GtkWidget:halign, #GtkWidget:valign and #GtkWidget:margin properties
  * on the child widget, so GtkMisc should not be used in new code.
  * </note>
