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 a GTK_NO_WINDOW widget. Remember
when using the PangoLayout functions you need to convert to
and from pixels using PANGO_PIXELS() or PANGO_SCALE.
