Sorry for extremely dumb question but I'm too slow and looks like I'm 
missing something.

It seems like people are capable to define procedural, that is, 
algorithmic textures and stuff (for example, normals), to be calculated 
by POVRay internally, to be used in scenes. I mean defining them as some 
sort of non-POVRay-specific built-in functions but rather as some 
general math function similar to that in general programming languages.

I, however, am unable to find any understandable docs regarding this. I 
guess I'm completely wrong somewhere - asking wrong questions, searching 
in wrong places, etc. Any ideas regarding what may be the right place to 
get something to read?
