Headless unit testing of Raphael.js is possible, and it's awesome

Yea, the purpose of the test is more to assert that the correct things are being called on Raphael. Since the actual code is so simplistic, these tests really aren't testing that much. In our actual implementation, the tests are actually testing legit logic.

I think that more important point of the post is that it is possible to test javascript graphics on the command line. That's something that's typically considered fairly difficult.
