thanks. It's good hearing of you again as well :)

I know. I've just seen the conversion to paths work with bitmap fonts as well 
today (only on Windows for now, but the X11 version will follow soon). So 
this is definitively solved for 4.0 :)

Btw, we are thinking about a paintengine for images, but this is something we 
won't have in 4.0. There are too many other things to do first.

I've noticed that in some other mail you've spoken about performance issues in 
QImage (scaling etc). I'd be happy to add optimised code for these things to 
Qt if you've got any that you are willing to contribute :)

Cheers,
Lars
