With this setup, the cells will be spread uniformally over the
area (``etesian.uniformDensity``), with ``80%`` of free space
added and an aspect ratio of ``100%`` (square shape).
With this setup, the placement will have ``80%`` of free space added and
an aspect ratio of ``100%`` (square shape). Some variations in density
is allowed, with at most ``10%`` unused space.
