Ok.

I found some more information in this thread:

From: Marc-Hendrik Bremer
Subject: Colors.inc-macros incomplete
Date: 9 Sep 2001 16:21:29

http://news.povray.org/povray.beta-test/thread/%3C3b9b9709%40news.povray.org%3E/

But there is no explanation for why the Convert_Color macro is missing.

IIRC, Rune organised the include files at that time. Maybe he can remember what
happened.
