/* Note: New in POV-Ray 3.1, the "ior" keyword is supposed to be 
         specified in the new "interior{...}" statement.  
  
         Under POV-Ray 3.0x and prior, the "refraction" keyword served
         two puropses.  
           1) Turn on refraction: this is no longer necessary.  Any use
              of the "ior" keyword with a value other than 1.0 will
              turn on refraction.
           2) Attenuate transparency: Values of "refraction" that are
              between 0.0 and 1.0 would attenuate or darken the amount
              of light passing through.  The same effect can be obtained
              by adjusting the filter value.  A more realistic effect
              can be obtained using the new "fade_power" and "fade_distance"
              keywords in the "interior" statement.
         These textures and finishes should still work under POV-Ray 3.1
         but any new textures you create should make use of the new syntax.
