Bresenham's line algorithm

I didn't formally studied computer graphics, so like many other areas of computer science, I get introduced to well-known ideas only when they appear in my line-of-sight. Years ago, when my son mentioned a college CS assignment using Bresenham's line algorithm, I'd never heard of it. I was attracted to the simplicity of the algorithm, and the fact that it addresses one of the earliest ad simplest computer graphics problems.
