        - fix <rdar://problem/5391540> REGRESSION: Can't drag images from Safari to applications
          in the dock (Tiger Preview, others in Leopard)

        * Misc/WebNSPasteboardExtras.mm:
        (-[NSPasteboard _web_declareAndWriteDragImageForElement:URL:title:archive:source:]):
        Re-implement code here that has been missing for the last couple of years since we
        did some image refactoring. Was pretty easy now that we can freely call C++ code
        in WebKit.
