>+        Extend DownloadClient so that it can handle the case where
>+        the download was triggered by a System Preview. In this situation
>+        the result (and progress) are piped into QuickLook via the SystemPreviewController.
>+
>+        The DownloadProxy class is also extended to handle the destination
>+        filename and the size of the content.
>+
>+        Lastly, SystemPreviewController is updated to have a start(), show()
>+        and cancel() interface, and no longer adjusts page navigation.
