Qt has some stuff in it's QTextLayout class (see 
QTDIR/src/kernel/qtextlayout*). It's not part of the public API in Qt3 
(mainly because it'll undergo some changes going to Qt4), but the API will 
stay stable (and binary compatible) within Qt3. A usage example can be found 
in qpainter.cpp:qt_format_text even though this might be quite a bit more 
complicated than what you need.

For Qt 4, I am currently working on a public API for text layouting.

Cheers,
Lars
