automatic conversio from expressive to receptive and vice-versa

[rocha at ATLAS.UCPEL.TCHE.BR]

Hi,

 At at first sight it seems that to produce an automatic conversion from
the expressive to the receptive mode of writing, it is enough:

  1) to mirror the image;
  2) to change the dominant fill (black) of arrows to the non-dominant
fill (white), and vice-versa.

  But I may be wrong...

  All the best,

  Antônio Carlos
