Antialias.
Ptoing, you've made all these excellent reference sheets. They are scattered all over the board. Any chance of a consolidated page showing/listing them all? Honestly, while I realize you aren't infallible in pixeling technique, these ref sheets are really helpful (and this one, at least, I reckon warrants being included/linked in the FAQ. )
The only significant thing that isn't included in this sheet is that AA looks best/cleanest, just as lines do, when the span of the line segments is a constant integer, as in
##....
..##..
....##
(and of course the percentages of coverage are the same for each row/column of the line, since the line is perfectly aligned to pixel corners; so less thought per pixel is required)
