Suggestion: Use instancing for three.js

[nzjony]

Three.js supports instancing, see: https://threejs.org/examples/?q=instanc#webgl_instancing_performance

This could potentially be offered as a means to render in three.js?

@nzjony Thank you for the suggestion! I’m not very familiar with Three.js so it may take a while. If you know how to do it and could submit a PR, I’ll gladly merge it asap!
