954 /** Set an offset in pixel
955
956 This method offsets every drawing operation that converts its
957 coordinates to pixel by the given value. Normally, the effect
958 can be achieved by setting a MapMode with a different
959 origin. Unfortunately, this origin is in logical coordinates
960 and can lead to rounding errors (see #102532# for details).
961
962 @attention This offset is only applied when converting to
963 pixel, i.e. some output modes such as metafile recordings
964 might be completely unaffected by this method! Use with
965 care. Furthermore, if the OutputDevice's MapMode is the
966 default (that's MAP_PIXEL), then, too, any pixel offset set is
967 ignored. This might be unintuitive for cases, but would have
968 been far more fragile to implement. What's more, the reason
969 why the pixel offset was introduced (avoiding rounding errors)
970 does not apply for MAP_PIXEL, because one can always use the
971 MapMode origin then.
