        #i30669#
        Because most of the Writer object positions doesn't correspond to the
        object positions in WW8, this method converts the positioning
        attributes. For this conversion the corresponding layout information
        is needed. If no layout information exists - e.g. no layout exists - no
        conversion is performed.
        No conversion is performed for as-character anchored objects. Whose
        object positions are already treated special in method <WriteData(..)>.
        Usage of method: Used by method <SetAnchoring(..)>, nothing else

        @param _iorHoriOri
        input/output parameter - containing the current horizontal position
        attributes, which are converted by this method.

        @param _iorVertOri
        input/output parameter - containing the current vertical position
        attributes, which are converted by this method.

        @param _rFrmFmt
        input parameter - frame format of the anchored object

        @return boolean, indicating, if a conversion has been performed.
