 *
 * Purpose:
 *  Requests that the active in-place object translate the message

 *  servers where the container's message loop is running.  EXE
 *  servers have control of the message loop so this will not be
 *  called in such cases.
 *
 * Parameters:
 *  pMSG            LPMSG to the message to translate.
 *
 * Return Value:
 *  HRESULT         NOERROR if translates, S_FALSE if not.

 *  fActivate       BOOL TRUE if the frame is active,

 *
 * Purpose:
 *  Informs the in-place object that the document window in the
 *  container is either becoming active or deactive.  On this call
 *  the object must either add or remove frame-level tools,
 *  including the mixed menu, depending on fActivate.
 *
 * Parameters:
 *  fActivate       BOOL TRUE if the document is active,

 *
 * Purpose:
 *  Informs the object that the frame or document size changed in

 *  document-level tools to match.
 *
 * Parameters:
 *  pRect           LPCRECT indicating the new size of the window
 *                  of interest.
 *  pIUIWindow      LPOLEINPLACEUIWINDOW pointing to an
 *                  IOleInPlaceUIWindow interface on the container
 *                  object of interest.  We use this to do
 *                  border-space negotiation.
 *
 *  fFrame          BOOL indicating if the frame was resized (TRUE)
 *                  or the document (FALSE)
