My name is Badrinath J. I am currently working for ThoughtWorks and was using the Gruff library to generate some graphs
for one of our projects. While doing this, we came across a method that was subclassed incorrectly.

While the Gruff::Base class defines the normalize method with an optional argument of force, set by default to false,
the method, subclassed in Gruff::Line does not define this argument.

We made a local patch that fixes this issue for us, but because we did not see any unit tests, we have not been able
to verify that this is a complete and sound fix. I am submitting the diff created by subversion. I hope that this is
the correct format for submitting a fix.

If correct, it would be great to see it incorporated soon so that we can remove our local monkey patch :)

Thanks a lot for your hard work in creating and maintaining this library.
