... but can be accomplished by surprisingly elegant and (comparatively) 
fast code in Assembler. (What surprised me even more was to see how a 
similarly elegant and efficient algorithm could draw a circle. No 
trigonometrics, not even a radix, just plain Assembler commands you'd 
find on a Z80 processor.)
