Description
Question
Should the geometricError of a tile take into account the scaling component of the tile's transform?
When testing with this example tileset, it seems the rendering result is more reasonable if the geometricError is affected by the transform's scaling.
I am unsure if this is expected behavior and would like clarification from the maintainers.

First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by loading the linked TilesetWithDiscreteLOD example and reproducing the rendering difference described in the issue. The payload names no source files or tests, so trace how tile transform and geometricError are handled, then confirm the expected scaling behavior with maintainers; done means the behavior is clarified and any agreed follow-up is defined.
