        contains even the filling so that the baseline is always preserved
        (ie. the text will not jump up and down according to whether it
        contains 'y' or not etc.)

    /** Set an offset in pixel

        This method offsets every drawing operation that converts its
        coordinates to pixel by the given value. Normally, the effect
        can be achieved by setting a MapMode with a different
        origin. Unfortunately, this origin is in logical coordinates
        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 MapUnit::MapPixel), 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 MapUnit::MapPixel, because one can always
        use the MapMode origin then.
