Rendered image files, which were pasted together into a single picture.

Here's a png of the simpler example, marked in red showing where the
blockiness appears always toward bottom right directions. AA options were
+a0.05 +am1 +j1.0 used. Contrast enhanced to make it show up better. And
yes, Ross is right, AA method 2 seems to be okay.
The original rendered file attached, also. All these images began as PNG, I
hadn't tried other formats until just now and see that it doesn't change the
artifact.
