Worker bundle size

[gchoqueux]

I analyze the Worker bundle size with :

1 • files import

import { Vector3 } from 'three/src/math/Vector3.js';
import { Quaternion } from 'three/src/math/Quaternion.js';
import { Box3 } from 'three/src/math/Box3.js';

2 • three package import

import { Vector3, Quaternion, Box3 } from 'three';

1 • files import	2 • three package import
660 KB	1,90 MB
