I think I started some experiments already with Pango, but didn't progress 
very far. But for now, I can live with the 'ugly' way and think some 
smarter way later on.

Next step is to find how to store the rendered text as pixmap/image and 
use that instead of every time rendering the text, because that seems to 
be awfully slow. And since I know when the text has to be rendered again 
and when I can use the pixmap (for eg. scrolling when text does not 
change, only the position), this is the best approach.
