Thank you, Bartc. I really appreciate that, especially in the context.

Ah, excellent! If you would be so kind as to point out, preferably in a 
reply to that article rather than this one, the bits you didn't agree 
with and why, perhaps we can drag a meaningful discussion out of this 
after all.

By the way, I anticipate at least a certain amount of intelligent 
disagreement over my choice of memory allocation strategy, and I can 
understand that. There's More Than One Way To Do It, and I like my way, 
and it works, but I realise that there are advantages to doing it in 
other ways. The OP might benefit from an "fewer mallocs" advocate's 
exposition of those advantages. (I could probably do it myself, but my 
heart wouldn't really be in it.)

Also, if I were writing the article over, I'd probably have made more 
(i.e. some!) use of the alpha channel in the SetColour function. My only 
excuse is that I forgot. I might even have taken the time to demonstrate 
Bresenham's line-drawing algorithm, and perhaps an ellipse plotting 
function.
