Bresenham:
Good job implementing the algorithm. Your code, though, looks a little
bit long. You could probably shorten it considerably by taking a look
at the special cases you listed out and combining them.

Cohen-Sutherland:
Overall a nice job at implementing it. However, I don't know about the
auxiliary classes. After all, line clipping is something we're going
to be wanting to do a hundred times a second -- the faster and slimmer
this code is, the better, and creating auxiliary classes just so you
can swap your points is probably not a worthwhile action.
