After this change, the relation between copy/move constructor calls in QtGui is something like 40/16. A moved-from QPen can only be copied, assigned-to or else destroyed. This required adding a nullptr check to the copy ctor and the dtor and rewriting copy assignment (which used non-nullptr-safe qAtomicAssign) in terms of copy construction and swapping. Extensive tests included. They are implemented such that they work in C++98 as well as C++11 mode, but they naturally test move semantics only in a C++11 build.
