/** method to perform conversion of positioning attributes with the help

    #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(..)>.

    @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 _rFrameFormat
    input parameter - frame format of the anchored object

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