Yes, indeed; it uses an approach similar to the oversampling implemented
in focal blur (but takes neighboring pixels into account to do its
adaptive thing).
Method 1 with jitter does indeed do a comparatively good job; but its
quality settings don't always scale well, as the attached image
demonstrates - this was rendered with +am1 and extremely high-quality
settings (+a0.01 +r9). Fun fact: With a lower numbr of samples, the
artifacts in the distance didn't show.
More importantly however, in the branch I'm working on the new
anti-aliasing mode will serve as a key component to speed up renders
that combine multiple features that rely on some kind of oversampling,
like focal blur, area lights, media, SSLT and (coming later) blurred
reflections.
