car brightness broken after collision export #12

Taking a vanilla cdb file and re-exporting it breaks car brightness for some reason.

Possible culprits:

there's a hidden invariant that requires surfaces (or some other data) to be ordered a specific way, which I violate
there's a lookup table in another file that needs to be kept in sync with the surfaces (and their ordering)
the scale factors for the coordinate system must be kept in sync with something (shadowmap extents? some .bed file?)

f270524 added shadowmap import. I tried manually aligning it, which was nontrivial. So I assume there must be a mapping defined somewhere, i.e. where does the shadowmap start and end? It doesn't look like the collision file contains this info, so I find it unlikely that the issue is related to the shadowmap, but I'll need to perform more experiments to narrow it down.
