            OutlinerEditView in the active text edit control.
            It now uses get2DDecomposition to decide if to process or not,
            thus it does not need to be processed in any B2DProcessor at all.
            This is also important e.g. for PDF export - if the object is in
            edit mode, we need to include the most current text from EditEngine/
            Outliner to that export which is contained here.
