Only with radiosity off does the re-factored code match 3.7.0 - 
otherwise none of the three match exactly.

No it is not empty. I'll dig more to try and figure out which finish 
statement(s) cause the difference & report back.

For the moment I am still working through the collection of materials I 
have just see if they all work & what the differences are. Still the 
case I've hit nothing that dies outright.

I'm also not sure if the aim is to always exactly match 3.7.0? In the 
case of media for example, we know we don't match 3.7.0 to 3.7.1, but we 
are happier with the 3.7.1 result.
