 *
 * Parameters:
 *  phWnd           HWND * in which to store the window handle.
 *
 * Return Value:
 *  HRESULT         NOERROR if successful, E_FAIL if there is no
 *                  window.

 *  is called.

 *
 * Parameters:
 *  prcPos          LPCRECT providing the object's full rectangle
 *                  relative to the continer's document.  The object
 *                  should scale to this rectangle.
 *  prcClip         LPCRECT describing the visible area of the object
 *                  which should not draw outside these areas.
 *
 * Return Value:
 *  HRESULT         NOERROR or an error code
