fn derive_position_bounds(positions: &[[f32; 3]], out_meta: &mut MeshMetadata)Expand description
Derive the position decode parameters from positions and write them into
out_meta.
The parameters are the bounding box the compression needs: positions
encode to [-1, 1] relative to it, which is what
mesh_compression.wesl reverses.

If positions is empty.
