No, there's no library, and yes, it'd be nice to create one.

What's been lacking is... you (kidding a bit) - in terms of a second use 
case. I find it hard to gauge for a single use case whether the stuff I 
create is sufficiently general (and hard to motivate myself to code 
things 'nicely' rather than quick and dirty without other users).

So what I usually do is that I develop stuff for one use case, then make 
it semi-official, develop it further to a generally usable technology in 
close contact with 2-3 aircraft maintainers and only once that satisfies 
everyone make it completely public and document it. Several features 
such as the thruster flame shader or the HUD shader got launched that 
way.

That allows for the possibility of controlled breakage of existing 
features in consensus with the involved early adopters.

(From an architecture POV, I suspect the best way to implement this is 
to have the code on FGData but not load it and let everyone who needs it 
io.include it from their files? Keeps the Nasal namespace lean...)
