/** @descr
    <p>This class essentially provides the text and view forwarders. If
    no SdrView is given, this class handles the UNO objects, which are
    currently not concerned with view issues. In this case,
    GetViewForwarder() always returns NULL and the underlying
    EditEngine of the SvxTextForwarder is a background one (i.e. not
    the official DrawOutliner, but one created exclusively for this
    object, with no relation to a view).
    </p>

    <p>If a SdrView is given at construction time, the caller is
    responsible for destroying this object when the view becomes
    invalid (the views cannot notify). If GetViewForwarder(sal_True)
    is called, the underlying shape is put into edit mode, the view
    forwarder returned encapsulates the OutlinerView and the next call
    to GetTextForwarder() yields a forwarder encapsulating the actual
    DrawOutliner. Thus, changes on that Outliner are immediately
    reflected on the screen. If the object leaves edit mode, the old
    behaviour is restored.</p>
