So therefore I don't expect any medal of honor from POV-Team for writting 
it ;) but this change would prouce a little bit better, or worse POV code ?
It would be same fast, or little bit faster AFAIK ?

And I want to get an idea i.e. by doing some (little) optimization myself.

It's my time so I think I will decide with optimization I want to 
implement, ok :) ?

Ok, but I do NOT want to code it ok ? I think I will implement a clip() for 
a "warm-up" and to get better along with pov's sources. Maybe inlining 
alsow - someday... :)

With files (and best - function names/lines) :

* have formulas for some literal functions like pow(a,b) ? (I want to see 
how it's done)

* now what should I do to add my own function (real-function) like i.e. 
my_function(a,b) and I want it's formula to be i.e.  (a+b)  for tests 
reasons. I quess I will have to change parser code, and functions code ?

* now I want to add function like  my_function(a,b,c) - it should be very 
simmilar probably ?

TIA
