fast PeirceQuincuncial #199

Open Fil opened 4 years ago

Fil commented 4 years ago

implementation by @jrus https://observablehq.com/@jrus/fast-peirce-quincuncial

see also the discussion at https://github.com/d3/d3-geo-projection/pull/194

Note that the default aspect is changed: peirceQuincuncial

I wonder if reval should not belong to a file of its own, since it can be used also for the conformal octahedron https://observablehq.com/@jrus/conformal-octahedron?collection=@jrus/maps and more projections to come?
