Hm, if your aim is pixel perfection, you really should return a qreal here, as 
with high DPI displays the difference between a 10 pt and an 11 pt font can 
be quite big.

The return value documentation says "biggest", the description says "optimal". 

As for the name, fontSize() sounds like an attribute getter, it should reflect 
the fact that it computes the largest possible font size, maybe call it 
adaptFontSize() to reflect the behaviour that it changes the size of the 
QPainter's font?

Other than that, this function is surely useful, maybe even in KMessageBox.

Not sure how the freeze dates apply here...
