I read a message by SamuelT.

He requested a feature to be able to multiply,
add, subtract, and difference, etc. pigments
and normals the following way:

add {
 pigment{wood}
 pigment{gradient y}
}

If that is possible, why not take it a step further?
What about being able to treat textures, pigments, and normals almost like
vectors?

Examples:

object {
 My_object
 pigment {
  pigment{wood} + pigment{gradient y}
 }
}

#declare Texture3 =
texture { ( Texture1 - 0.3 ) * Texture2 + 0.6 }

#declare LowBumps =
normal { HighBumps / 5 }

This is not at all a complete and finished idea.
Just something I thought might turn into something useful.

Would it be possible?
