I never said that you did.

Which, of course, is contradicted by the 20-year-old reference that I
cited (see the test images in Figure 14.3 of that reference, for
example). Strictly speaking, "implement [anti-aliasing] for 2d vector
graphics" is not meaningful, since aliasing is not a characteristic of
2d vector graphics, but is rather a characteristic of the sampling
process, which typically occurs during conversion of an image (vector or
otherwise) to a pixel- or scanline-based representation.

In any event, all anti-aliasing techniques are based in some way or
another on sampling theory.

A "rule of thumb" is something that is valid most of the time, but not
necessarily all of the time.
