    GtkOverlay: Update the description
    
    State that the overlays are placed wrt to the GtkOverlay, not
    with respect to the main widget. This makes a difference for
    small main widgets which are not configured to fill the entire
    GtkOverlay.

  * @title: GtkOverlay
  *
  * GtkOverlay is a container which contains a single main child, on top
- * of which it can place “overlay” widgets. The
- * position of each overlay widget is determined by its #GtkWidget:halign
- * and #GtkWidget:valign properties. E.g. a widget with both alignments
- * set to %GTK_ALIGN_START will be placed at the top left corner of the
- * main widget, whereas an overlay with halign set to %GTK_ALIGN_CENTER
- * and valign set to %GTK_ALIGN_END will be placed a the bottom edge of
- * the main widget, horizontally centered. The position can be adjusted
- * by setting the margin properties of the child to non-zero values.
