* viewer :

- No more flickering. Was due to a one pixel moving of a two
       pixel periodic pattern, which obviously result in a complete
       pattern inversion. Now shift by two pixels, hoping there is
       no "3 pixels periodic" patterns...
   - As a side effect, it introduce a "multiplicator effect" on
       mouse movement, but it could be useful (avoid big displacement
       of the mouse).
