Can I scale only image that is used in material_map leaving all used 
textures unchanged ? 
I.e. I have 

box { ... 
  texture {
    material_map { png "..."
      texture { A }
      texture { B }
    }
  } 
}

textures A & B are i.e. bozo. And now I want to streach image to cover 
entire box but WITHOUT changing scale of texture A and B I have to do :

  texture { #local S=<2,3,1>;
    material_map { png "..."
      texture { A scale 1/S }
      texture { B scale 1/S }
    }
    scale S
  } 

and if I want to use other transforms - it gets more complicated and little 
uncomfortable IMHO
