Functions
auto	boat::geometry::ortho (geographic::point const &v)
	Orthographic SRS centered at v.
srs_variant	boat::geometry::to_srs_variant (auto const &meta)
	Prefers a positive epsg code to proj4; throws if neither is available.
auto	boat::geometry::transformation (srs_spec auto const &a, srs_spec auto const &b)
auto	boat::geometry::transformation (srs_spec auto const &v)
	Creates a transformation from WGS 84 longitude/latitude to v.

template<tagged T1, same_tag< T1 > T2, class Strategy>
bool	boat::geometry::transform (T1 const &geom1, T2 &geom2, Strategy const &strategy)
auto	boat::geometry::transform (auto const &... strategies)
	Composes strategies and returns std::nullopt if a transformation fails.
