I hadn't (but have now). I already knew about anti-aliasing, though. I
work in desktop publishing. My employers have their own graphics library
which uses subpixel accuracy and anti-aliasing. I didn't design it but I
work on and with it. It seems roughly similar in functionality to the AGG
project, except that we place a lot of importance on text and vectors and
I can't find text mentioned on their manual page. We find that for sending
output to printer or PDF or whatever, it's important to output text as
text as much as possible and only output as bitmaps for features the
target device doesn't support.

Anyway, yes, anti-aliasing helps, and is the only way to deal with curves,
but grid-fitting gives better results where possible. As Stefan Seefeld
says later, we can't hide the pixels completely.
