       SippCone bottomradius topradius length resolution shaderhandle [texture]
              Create  a  cone  centered about the origin and with
              the z-axis along the cones main axis.  The  surface
              is shaded with the algorithm and surface parameters
              specified by shaderhandle.  bottomradius and topra-
              dius  determines the radius of the cone in its bot-
              tom and top, if both of these are non zero a  trun-
              cated cone is created. length defines the length of
              the cone.  resolution is  the  number  of  polygons
              that will be created radially around the rim.

              Texture is the texture mapping algorithm to use for
              the object.  The NATURAL texture mapping is  CYLIN-
              DRICAL.

              See  the help file tsipp/primitives/Texture-Map for
              more details.

              An object handle that references the new object  is
              returned.
