No argument. That's why I said I realized this was always done for you today. But somebody had to build and program that GPU, and for those of us who care about such details, it would be nice to learn how rasterization works in a GPU. I had assumed that GPUs were still using Bresenham-like DDAs, but I learned from the above discussion that fixed-point non-branching algorithms may have become more common.
