If you want Pango to do the drawing you need to use the high-level
formater; if we use the low-level stuff, we would do the drawing
ourselves, just as we do now.

With the low-level API we would do this ourselves, as we do now.

See comment on point 1.

It is an option, but either you use Pango or ICU. But the ICU library
is somewhat bulky from what I have seen.

Martin, the API is not an issue at the moment, so do not vaste
your time. Pango needs to be protable first, and we need to find out
how much work we would have to put in to make it portable, and if
we have the resources and expertize to pull that off (see my
posting addressed to Havoc).

Next genration, as in 24th century? No, seriously, can we afford to
budget with functionality that is not there?
