I noticed that rendering patterns in POV-Ray 3.1 and 3.5 give different
results.  Rendering in POV-Ray 3.5 with the following texture (as given by
Ricky[Kitty]5 in povray.binaries.images under 'more glass balls...') yields
a very soft pattern to objects this material is applied to.  But when
rendered in POV-Ray 3.1, the pattern appears much more defined.  Why the
change?  Is there any convention to use so that a scene with materials
intended to be rendered in POV-Ray 3.1 can be rendered in POV-Ray 3.5 with
the same look, or is it just a matter of manually tweaking?
I've posted images in povray.binaries.images comparing the same pattern
rendered in 3.1 and 3.5.

#declare Material1 =
   material  // Material1
   {
      texture
      {
         pigment
         {
            color rgb <1.0, 1.0, 1.0>
         }
         normal
         {
            bozo , 0.5
            turbulence 0.5
            ramp_wave
         }
         finish
         {
            ambient 0.0
            diffuse 0.6115
         }
      }
   }
