%global common_description %{expand:
Python bindings for the C++ implementation of the Mapbox Earcut library, which
provides very fast and quite robust triangulation of 2D polygons.

Original code: earcut.hpp

Original description:

    The library implements a modified ear slicing algorithm, optimized by
    z-order curve hashing and extended to handle holes, twisted polygons,
    degeneracies and self-intersections in a way that doesn’t guarantee
    correctness of triangulation, but attempts to always produce acceptable
    results for practical data like geographical shapes.}
