(with reference to my post in povray.advanced-users)

This file demonstrates a way in which a variable can store a reference to a
macro. And this variable can be used to indirectly invoke that macro. This is
equivalent to function callbacks in C, or class methods in C++.

It can be pretty handy if you want to define a lot of different macros with the
same interface, and call them from code which is independant of the macros
themselves.

Let me know if this is any good! :)

P.S. sorry for the double-post, I've been quite productive this evening!
