       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 is a factor which determines the size of  the
              granite  pattern  depending on the size of the tex-
              ture coordinate system in  relation  to  the  world
              coordinate system.

              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.
