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