Just that it's clear that not all are automatically generated:
at least the Finnish border at the sea between Finland and Sweden
(and Estonia) was translated (another coordinate system) from a Finnish law
containing the corner points - the zones of different countries
even meet at three sections, and thus affect the distance from
the shore.
