I think a variable should be documented if anyone will ever need to know what 
it does - and that probably includes almost all variables. I have talked with 
Scott in the past about some kind of labelling system for the variable 
glossary so you can see at a glance where the variable is supposed to be used 
and (hopefully, if we can come up with sane categorisation) when it's 
appropriate to modify.

IMO, all of those you listed should be documented. I've just entered a bug 
about documenting the tune files / variables at least:

Cheers,
Paul
