A lattice rather than a scatter, because a scatter leaves gaps a small object falls into and
a lattice does not; the seeded jitter is there so that a repeated object does not land on the
same part of every instance, which is how a grid misses the same feature twice. Two per pixel
pair — x then y — in reading order, which is the order a model's masks come back in.
