I see you've found the problem. There are kinds of graphics systems: those which include
the final point, and those which do not. Each has its own set of unique problems. In the
"coin toss" of the decision, Microsoft chose the non-inclusive model. I've worked in
both, and both will drive you nuts at the boundary conditions.
