Title: Some improvements

Hi,

As suggested by you, I forked your repo and made a few changes. Now I want you to notify
about my changes, so if you want you may take my changes in your repo :)

What I did:
* Added `--help` switch
* Reduced memory usage - even if just a little bit - using xrange() instead of range()
* The width of the image is an additional, optional argument. (sys.argv[2]). Everything gets scaled
to this resolution. (The distance, the font size, ...)

Try it, I hope you think it could be useful!
