    around.

    at the expense of resolution.

the ordered dithering matrix. To get the old behaviour, use:
      pipi image.png pipi:bayer8 --dither ordered out.png

* pipi.c: add "--blur" and "--dither" commandline options.
  * blur.c dither.c: remove these examples, pipi.c works a lot better:
     pipi src.png --blur 10 dest.png
     pipi src.png --dither dbs dest.png
    (and of course combinations are possible)
