/** @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>
