I just posted a quick outline, earlier this week. If you've been on the
list that long, search back for the phrase: Aliasing is what happens when
an image boundary crosses an individual pixel.
I'll do a webpage, as ASCI just doesn't work too well for something which
graphics make obvious. This week. Somehow ;)
