Of course! I've got to admit that was a pretty brain-dead question.
Makes perfect sense now that I see it in print. Looking now, it's easy
to see that the AA on the right side of a thin line looks better than
that on the left.

Absolutely. I remember someone writing a patch like this once. Each ray
would check the center and the corners of each pixel before deciding
whether to super-sample.

Thanks, guys.
