Rendering: objects are removed and added again for each animation frame.

[freddida]

Describe the issue
I did a performance test between native threejs and gtlf-transform-view rendering. I found out that certain operations with view degrade the performance enormously. In my example I scale several cubes in the renderloop.

Observation
The objects are removed and added again for each animation frame.

Question
Can you explain me the advantage of this method?

If you need further explanation I can provide a minimal example.

Versions:

• Version: [2.1.5]
• Environment: [Visual Studio Code / Chrome]

Hi! While there are conditions that might cause objects to be removed and re-added, changing the scale of a node is not supposed to be one of them. So I think this is probably a bug. Would you mind opening an issue on the https://github.com/donmccurdy/glTF-Transform-View repository with a few more details? I think knowing what code you are running in the render loop (just node.setScale([x, y, z]), or more?) might be enough. Thanks!
