Same as fill-rule attribute in SVG, the left is nonzero, the right is evenodd.

Since earcut is not supported self-intersecting paths well, we use libtess.js to tesselate the path.

const star = new Path({
    d: 'M150 0 L121 90 L198 35 L102 35 L179 90 Z',
    fill: '#F67676',
    fillRule: 'evenodd',
    tessellationMethod: TesselationMethod.LIBTESS, // instead of earcut
});
