Viewer param pickSurfacePrecisionEnabled

[g-rodigy]

According the docs https://xeokit.github.io/xeokit-sdk/docs/class/src/viewer/Viewer.js~Viewer.html
Viewer param pickSurfacePrecisionEnabled set to true and do pick like this:

const viewer = new Viewer({
    canvasId: "myCanvas"
});

viewer.pickSurfacePrecisionEnabled = true;

viewer.scene.input.on('click', (coords) => {
    const hit = viewer.scene.pick({
	canvasPos: coords,
	pickSurfacePrecision: true,
	pickSurface: true,
	snapToEdge: true,
    }, new PickResult())

    // hit.pickSurfacePrecision is false
})

Setting param here

xeokit-sdk/src/viewer/Viewer.js

Line 118 in e842ad8

pickSurfacePrecisionEnabled: (!!cfg.pickSurfacePrecisionEnabled),

but not used in Scene class or I not found.

Does this param works and/or why pickSurfacePrecision is false?
