Obtains the coordinates where the label will draw the #PangoLayout
representing the text in the label; useful to convert mouse events
into coordinates inside the #PangoLayout, e.g. to take some action
if some part of the label is clicked. Of course you will need to
create a #GtkEventBox to receive the events, and pack the label
inside it, since labels are windowless (they return %FALSE from
gtk_widget_get_has_window()). Remember
when using the #PangoLayout functions you need to convert to
and from pixels using PANGO_PIXELS() or #PANGO_SCALE.
