thinking aloud about the simulation, and not having used 'f_wood()' yet, as user
I think I'd like one simple (wrapper) function/macro where, ideally, I'd only
provide an "age" (ie #rings) and some average "annual" growth value to obtain a
pattern, and maybe a rand seed.  (I guess all eight parameters will be needed
when "tuning" some aspect(s) of the render)

unrelated, but I've only found out about two _exciting_ Tcl extensions; thinking
that when 'povr'/POV-Ray compiles, the "library" of backend stuff which is
linked late in the process, I'm fairly certain, could be (mis-)used ;-) with
either of these:
