ContourIntervals

object ContourIntervals(source)

The zoom-banded contour interval table, ported verbatim from the sibling iOS app's ContourGenerator.swift:38-58 (ContourIntervals.intervals(forZoom:metric:)). indexMeters is always 5 × minorMeters in every band; every 5th minor line is an index line.
