GtkOverlay: Update the description

Browse Source 
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.
