For every class that defines an "operator QVariant()" I have added a ctor that
takes a single "const QVariant &" argument that is implemented using
qVariantValue(). So all you need to do is to pass the QVariant instance to
the QPixmap ctor.
I've finished the port of puzzle and it's in the current snapshot.
