No need for PangoContext, just follow the code example given with
your link. If using the new Cairo, you create a Cairo surface, from
this a Cairo context (cairo_t), and from this the PangoLayout. Also,
don't forget to close a PdfSurface, else the file won't be written.

I failed, however, to implement it using Cairomm and Pangomm, due to
two bugs which I have reported.
