>   class OptionsChangingMessage : public Msg

    Author:     Neville_Humphrys (Xara Group Ltd) <camelotdev@xara.com>
    Created:    3/1/1995
    Purpose:    This message is sent when a user has changed the options on a document or
                a global application based option. At present the messages include:-

                NEWUNITS messages are broadcast when the user has specified new display, page
                or font units are to be used.

                An OptionsChangingMsg contains a pointer to the appropriate Document
                object (pScopeDoc), and a state indicating the option that is being changed.
                Both members are public.
