I did that because KDE/Qt 3 needed a widget instance to be able to draw, and 
it looked to me as a waste of resources allocating and freeing it with every 
paint event; it was not really meant as an optimization originally, just a 
need ;-) - I would have been much more happy if the instance of the widget 
was not necessary.

An equivalent in KDE/Qt 4 seems to be remembering the QStyleOption objects 
(eg. by doing them static), but I suppose this would be worth profiling 
first.
