path-warp-paper.js 
Warp a path to fit other boundary paths. Paper.js implementation.
Installation
npm install path-warp-paper
Usage
The feature is registered as an extension to Path and CompoundPath in Paper.js.
Paper.js is built for canvas rendering, but it can also be used as a calculation library unattached to canvas (export elements to SVG).
Canvas render
import paper from 'paper'
import PathWarp from 'path-warp-paper';
paper.setup('canvasId');
new PathWarp().register(paper);
const top = new paper.Path(...);
const bottom = new paper.Path(...);
const target = new paper.Path(...);
target.warpBetween(top, bottom);
SVG render
paper.setup();
new PathWarp().register(paper);
const top = new paper.Path(...);
const bottom = new paper.Path(...);
const target = new paper.Path(...);
target.warpBetween(top, bottom);
cosnt svgPath = target.exportSVG();
document.getElementById('svgId').appendChild(svgPath);
