Using a clone for the drag actor causes the animation into the final position not to work as expected; instead use the newly added DND parameters to change the original drag actors size and opacity. (This reverts the change in 011db9f). Since we are using the original actor, we have to be careful not to change it during the drag, so don't actually position dragged window actors in Workspace.positionWindows(). https://bugzilla.gnome.org/show_bug.cgi?id=613367
