 * class CXMLIcon
 *
 * This class adds XML persistence to CSmartIcons.  CSmartIcon cannot
 * implement XML persistence on its own because it is used in the shell
 * extension.  The shell extension must be extremely lightweight, but
 * XML persistence requires mmcbase.dll.  Depending on mmcbase.dll would
 * make the shell extension too heavy, so we have this functionality split.
