Projection naturalEarth supports pacific view or other projection center

[zxj5470]

Motivation

I found that the projection naturalEarth uses the code by d3-geo. But current view is only centered by [0, 0] .

And d3 has other center view like pacific by using .rotate([200, 0])， by offset
（This API named rotate is an Ambiguous name, and 200 means -160 means 160°E，wtf）

The features what I want is add an API named like offset in natural_earth.js to set longitude 160°E as center when changing projection.

map.setProjection({
  name: "naturalEarth", 
  offset: [160, 0], //  pacific as center
})

Implementation

d3-geo code:
https://github.com/d3/d3-geo/blob/0c27527d4f9f500698b28d33289ee1104ee22990/src/projection/index.js#L157-L165

// code usage
projection = d3.geoNaturalEarth1().rotate([200, 0])


  projection.rotate = function(_) {
    return arguments.length ? (deltaLambda = _[0] % 360 * radians, 
deltaPhi = _[1] % 360 * radians, 
deltaGamma = _.length > 2 ? _[2] % 360 * radians : 0, 
recenter()) : [deltaLambda * degrees, deltaPhi * degrees, deltaGamma * degrees];
  };

  function recenter() {
    var center = scaleTranslateRotate(k, 0, 0, sx, sy, alpha).apply(null, project(lambda, phi)),
        transform = scaleTranslateRotate(k, x - center[0], y - center[1], sx, sy, alpha);
    rotate = rotateRadians(deltaLambda, deltaPhi, deltaGamma);
    projectTransform = compose(project, transform);
    projectRotateTransform = compose(rotate, projectTransform);
    projectResample = resample(projectTransform, delta2);
    return reset();
  }

Yeah, we would like to implement this eventually, although it's not trivial for GL JS. Closing as duplicate of #11180
