If you declare the 'accuracy' of a normal inside a texture, and then apply
that texture to an object, it doesn't take effect:

camera {
 location -z
 look_at 0
}
light_source {
 <-1,1,-1>*9999
 rgb 1
}

#declare tex = texture {
 pigment {rgb 1}
 normal {
  crackle solid
  accuracy .0001
 }
}

plane {
 -z,0
 texture {tex}
}

Copying and pasting the texture right into the object makes the accuracy of
the normal work as expected.

Anyone care to confirm?
