We could deprecate QRect and QRectF, and introduce a proper QRectangle. It 
should be doable by means of an implicit QRect(const QRectangle<int> &) 
constructor and an operator QRectangle<int>() const.

If that doesn't work, it would unfortunately mean deprecating all of the API 
that uses QRect and QRectF and add new API.

But by the same token that Andreas has of subtle bugs, this change would 
introduce subtle bugs in Qt code that relies on the quirky QRect behaviour.
