[PyKDE] Implementing QSimpleRichText

[Eron Lloyd]

Hey thanks. I thought about the idea of creating pixmaps, but I would really 
like to understand the intrinsics of QPainter and friends, as I'm in the 
process of developing some pretty complicated UI stuff and would like to take 
full advantage of the drawing primatives. Perhaps this is something to ask 
for in Qt4 (as part of the Interview framework, perhaps).

Regards,

Eron
