Jonathan has finished his time with us at Palaso (Thailand) and returned
to the US. I'm currently working on the 2.4 packaging for debian and
our own package, then I'll be able to have a look at the pango work
again (say in a couple of weeks time).

I'd like to see this committed. We're very nearly finished with our
re-engineering / refactoring of the TextBoxTextRenderer to support pango.

There's also quite a bit of work in the TextBoxTextRenderer which has
undergone quite a lot of change. So far, it seems good enough for our
purposes. Rendering right to left, burmese, and other non-roman south
east asian languages.
I expect to follow up on this in a couple of weeks time.
