Description: Densify lines adaptively, as required by the curvature a
        map projection imposes on them. Edges are read as great circle
        arcs, and vertices are inserted along them only where the
        projected curve deviates from a straight chord by more than a
        tolerance measured on the map, following the adaptive
        resampling method of the 'd3-geo' 'JavaScript' library
        described in Bostock (2016) <https://github.com/d3/d3-geo>.
        Projections are computed with the 'PROJ' coordinate
        transformation library (<https://proj.org/>), so any coordinate
        reference system it supports can be a target. Inputs can be
        coordinate matrices, segment meshes or vertex pool topology
        from 'wkpool', and edges shared by neighbouring polygons
        receive identical new vertices.
