      Dragged elements are blurred on Retina screen.

      It affects default dragging (for example, from QListWidget), but also custom drag operations.

      QDrag with QPixmap of pixel ratio value 2.0 is shown 2x bigger than it needs to be.

      Attached a screenshot and a sample project.

      Found initially on Qt 5.4, but now checked with qt-opensource-mac-x64-clang-5.5.0-beta_2015-05-11_07-25-48-56.dmg
