 *  DESCRIPTION: Image transfer plugin declarations for the scanner and camera wizard
 *
 *  1.  Implemented as an inproc, apartment-threaded COM component.
 *
 *  2.  Component to display UI *only* during IImageTransferPlugin::OpenConnection.
 *
 *  3.  UI displayed during IImageTransferPlugin::OpenConnection should be a modal dialog
 *      using hwndParent as the parent window.  This window may be NULL.
 *
 *  4.  The icon returned from IImageTransferPlugin::GetPluginIcon must be
 *      copied to a new icon using CopyIcon.
