i965/guardband: Improve comments for guardband clipping

While working in this part of the code I had a great deal of trouble
understanding what it was trying to do, and matching it with the spec.
(mostly due bad wording in the PRM). To help future people, I've cleaned
up the wording and provided some ascii art.
