* Add two extra optional arguments to
QPDFPageObjectHelper::placeFormXObject to control whether the
placed item is allowed to be shrunk or expanded to fit within or
maximally fill the destination rectangle. Prior to this change,
placeFormXObject might shrink it but would never expand it.

* Add method QPDFObjectHandle::unsafeShallowCopy for copying only
