There's no QPoint3D in math3d. Therefore, we're talking about a new class, so 
a new feature, so Qt 5.1.

I am interested in knowing what you plan on doing to QVector2D, QVector3D and 
QVector4D.

Yes, I do understand perfectly. I have decided not to add my own extremely 
important changes to Qt 5 because it's just too late. And I am sure I did 
quite a good job at investigating the consequences (I am running the changed 
code and I compiled all modules). I'm not so sure you did.

I don't see a problem with a QPoint3D and QPointF3D class in QtCore, in 
Qt 5.1, provided you also fix any ambiguities with QVector3D's existence.

PS: your commas are weirdly placed.
