Points unaffected by object hierarchy scale

Expected behavior

Expected Points with { sizeAttenuation: true } on the PointsMaterial to have its render size to be affected by object hierarchy scale. Own scale or parent scale, etc.

Live example

Steps to reproduce the behavior:

1. Go to https://jsfiddle.net/98u1j5x3/
2. see render function
3. observe behavior

Platform:

• Three.js version: dev

Yeah, this is one of the open points in context of WebGPU. Meaning how to treat THREE.Points. Right now, the renderer uses the point-list primitive for rendering but that will break many existing use cases considering how THREE.Points is used in WebGL.

Also keep in mind that with WebGPU, points will always have the size of 1 pixel and something like sizeAttenuation is not supported anymore.

Hmm, we may need to render THREE.Points using instanced planes facing the camera in WebGPU. Otherwise THREE.Points will not be very useful…
