Fix drag curor visibility on Windows.

QDrag has an API to set both pixmap (QDrag::setPixmap) and drag cursor
(QDrag::setDragCursor): http://qt-project.org/doc/qt-5.0/qdrag.html.

We cannot return from createCursors if there is no pixmap, but we need
to go through also dragCursor and use those if one is set.
