I looked at this a while ago and it appeared that there would be a significant 
performance penalty in getting to a QImage and on to a QPixmap. Direct drawing 
to the screen is fast but it ain't a QPixmap.

This doesn't mean it is a bad idea though. Using it to convert images which 
kimgio/qimageio doesn't handle would be nice. Ditto for imagemagick, I suppose. 
Wouldn't want the rely on them though.
