i remember that when a while ago taco and i discussed this that there 
were some good reasons for not yet having access to all this specific 
info i.e. i can imagine that tex.somefontcs returns the number but quite 
some of those accessors have to wait till the whole global/local issue 
of the code is resolved.

also, we're not close to 0.50 so it's unlikely that new accessors will 
show up before that stable version is out
