KSpread uses QPainter's scale method nowadays. :)

To bring it to the point: I'd like to let the fonts of the cell content at 
100 % zoom have the same size as those in the tool-/menubar. And that's not 
the case, if I just rely on QPainter::scale() (see attached sreenshot). If I 
do the extra scaling it fits well. The difference is marginal, but it exists. 
And my crystal ball tells me, that users will ask about that fact. (They did 
already about the font size of the headers in the dot article, as you may 
know.)
The scaling factors of KZoomHandler depend on X's dpi (aka. ppi) info. For me, 
it's 86x86 dpi. But others may have higher value (about 100 or similar), 
which extends the discrepancy.

Regards,
Stefan
