Just checked it out and found that transformations are not used in shader
pigments.  For example

#declare myWaves=function{
  pigment{
    shader{
      shader_file "waves.slp"  
      "scale" 10
    } 
    scale 0.001
  }
}

in this scene does not change anything, which seems wrong to me.  

BTW, those shaders are interesting stuff, but they are quite difficult to
learn for someone used to povray :-)
