        and can lead to rounding errors (see #102532# for details).

        @attention This offset is only applied when converting to
        pixel, i.e. some output modes such as metafile recordings
        might be completely unaffected by this method! Use with
        care. Furthermore, if the OutputDevice's MapMode is the
        default (that's MAP_PIXEL), then any pixel offset set is
        ignored also. This might be unintuitive for cases, but would
        have been far more fragile to implement. What's more, the
        reason why the pixel offset was introduced (avoiding rounding
        errors) does not apply for MAP_PIXEL, because one can always
        use the MapMode origin then.
