I remember many years ago finding a very idiotic book in the library about assembly language programming (Motorola 68000) on the Apple Mac. The textbook presented a circle-drawing routine, and bragged about it only takes a quarter second (don't remember the exact time unit) to draw a big circle, thanks to being written in assembly language! I thought, what? On the same machine, the classic MacPaint program draws fat ellipses at a decent enough frame rate that you can interactively resize the suckers. Haven't these authors ever used any applications on a Mac? So I looked at what their routine was doing. It was using the naive algorithm based on square root instead of Bresenham!
