-/*
- * tabletranstemplate.c - template for translation using lookup tables.
- *
- * This file shouldn't be compiled. It is included multiple times by
- * translate.c, each time with different definitions of the macros IN and OUT.
- *
- * For each pair of values IN and OUT, this file defines two functions for
- * translating a given rectangle of pixel data. One uses a single lookup
- * table, and the other uses three separate lookup tables for the red, green
- * and blue values.
- *
- * I know this code isn't nice to read because of all the macros, but
- * efficiency is important here.
