       SippShaderBumpy shaderhandle scale [BUMPS] [HOLES]
              This shader is a function that perturbates the nor-
              mal of a surface using noise().  Any  other  shader
              can be used to do the final shading calculations.

              shaderhandle is a handle to another shader and sur-
              face specification.

              scale describes how much  the  texture  coordinates
              should  be scaled before applying the texture.  The
              larger the scaling, the smaller  the  area  of  the
              texture  associated  with  a given area of the sur-
              face.  A large number results in a very  fine  pat-
              tern, a small number yields a coarse pattern.

              BUMPS  indicates  that only bumps standing out from
              the surface are visible, the rest of the surface is
              smooth.

              HOLES indicates that only bumps going into the sur-
              face are  visible,  the  rest  of  the  surface  is
              smooth.   If  neither  HOLES or BUMPS or specified,
              then both are assumed to be on.
