Yes; it would be nice to have this also for clipAngle — in your notebook it works by using: ``` { const clipAngle = d3.geoClipCircle(50/180*Math.PI); return d3.geoProject(land, {stream: stream =>...

Proposed API: - clip.*clipPoints*(false) would not clip the points only lines and polygons. or: - clip.*pointTolerance*(epsilon) keep points close to the edge (default: epsilon) 🤔

For the moment I don't see very well how the Antarctica piece is made in Steve Waterman's original — the angles and the parallels in my draft are not the...

Solved in https://beta.observablehq.com/d/71ce78c6ae5001fa for all "interrupted" projections of d3-geo-projection, including HEALPix.

Have to think about how to integrate this — I'd rather not duplicate all the code from geo-projection, but for users I want it to be as simple as adding...
