Problems regarding the Bresenham line algorithm

Understand your lab5 program better.
Go through sample calculations for the Bresenham line algorithm for specific numbers, where x2>x1 and y2>y1 always (because those are the only cases we're examining in detail for this course, mostly because the other cases are similar but there are a lot of cases).

For lab5, compare your program to my distributed sample solution (in /u/ajr/104/lab5/bres.py) and see which is better and ask me about it.

For specific sample calculations, compare your results to the discussion generated at http://course.dgp.toronto.edu/cgi-bin/bres
