 * For a given projection, apply a zoom factor to the scale and return the rotation that renders
 * `geoPoint` at the `to` pixel coordinates, as `[longitude, latitude, roll]` (the view `center` plus
 * the third d3 rotation angle).
 *
 * - With `rotationAllowed: 'both+roll'`, the roll is free to move but kept as stable as possible: the
 *   shortest-arc rotation dragging `geoPoint` onto `to` is composed with the current orientation, so
 *   the roll only drifts as much as strictly required.
 * - With `rotationAllowed: 'both'`, both longitude and latitude are free but the roll is kept fixed at
 *   the current value.
 * - With `rotationAllowed: 'longitude'`, only the longitude is solved; the latitude and roll are kept fixed.
 * - With `rotationAllowed: 'none'`, `null` is returned so the caller keeps the current rotation.
