What is the best way to extend the trois.js library [https://troisjs.github.io/](https://troisjs.github.io/) to be able use the scattermesh example? [three.js examples](https://threejs.org/examples/?q=scatter#webgl_instancing_scatter)

when i understand it correctly, the meshsurfacesampler.js ([three.js/MeshSurfaceSampler.js at 724575ae82a282f468e15eb69a241ea0b29bba62 · mrdoob/three.js · GitHub](https://github.com/mrdoob/three.js/blob/724575ae82a282f468e15eb69a241ea0b29bba62/examples/jsm/math/MeshSurfaceSampler.js)) is missing. What would be the best way to implement it in trois?
