Well, there are are bug reports asking for qHash(QPoint), so it seems to make 
sense to _someone_ :)

Esp. for types that don't have a natural total order (=most), and thus don't / 
shouldn't have operator<, adding a qHash() overload, as long as it can be done 
(it can't for QPointF) is the only way to enable associative containers of any 
kind for that type.

Thanks,
Marc
