Source code changes of the file "python/caca/dither.py" between
libcaca-0.99.beta19.tar.gz and libcaca-0.99.beta20.tar.bz2

About: libcaca is a graphics library that outputs text instead of pixels, so that it can work on older video cards or text terminals (something like an advanced AAlib library).
