This pattern gets the 3D gray values
from any pigment as a pattern for
color_map, pigment_map,
textur_map or normal_map.
We can use it with patterned pigment,
from simple to very complicated nested.
Note: For the use of these patterns in normal statements
we can use an additional value for Bump_Size !
