I'm not entirely sure where to find these mappings in the TRM. I see
that there's a list of the groups in 15.10.11, but where do the numbers
come from? And why are some of the names aliased? If it's for
readability only maybe we could add some more for SWGID_HC ->
SWGID_HOST1X and perhaps SWGID_NV -> SWGID_GR3D.
