Research direction

Read Turf's packages/turf-transform-scale/index.js, especially the listed dependencies, then locate the corresponding Turf package in this repository. Port the transformScale method and verify that the Java package provides equivalent scaling behavior to the referenced Turf implementation.

Description

Turf

Have seen some maps examples in the wild that do some interesting data visualization with "radiating" Polygon FillLayers. This is possible with Mapbox but it'd be a lot easier to do this with the Turf transformScale method

Port https://github.com/Turfjs/turf/blob/master/packages/turf-transform-scale/index.js to this repo's Turf package. Looks like this method uses a lot of other ones
