I think we agreed on the former, but hopefully not on the latter. Many 
geometric classes, such as QLineF, have functions that are used 
outside rendering, so having double-precision classes are very useful 
to have.

Maybe add explicit QRectS and QRectD classes, and deprecate QRectF 
(same for QPointF, QLineF and friends)?
