The only normal patterns and modifiers that were available in POV-Ray v2.2
are as follows -

        5.4.2   NORMAL
                5.4.2.1 Bumps
                5.4.2.2 Dents
                5.4.2.3 Ripples
                5.4.2.4 Waves
                5.4.2.5 Wrinkles
                5.4.2.6 Bump_map
                        5.4.2.6.1   Specifying a bump map.
                        5.4.2.6.2   Bump_size
