     * %SHADING Color shading mode.
     * %   SHADING controls the color shading of SURFACE and PATCH objects.
     * %   SURFACE and PATCH objects are created by the functions SURF, MESH,
     * %   PCOLOR, FILL, and FILL3. 
     * %
     * %   SHADING FLAT sets the shading of the current graph to flat.
     * %   SHADING INTERP sets the shading to interpolated.
     * %   SHADING FACETED sets the shading to faceted, which is the default.
     * %
     * %   Flat shading is piecewise constant; each mesh line segment or
     * %   surface patch has a constant color determined by the color value
     * %   at the end point of the segment or the corner of the patch which
     * %   has the smallest index or indices.
     * %
     * %   Interpolated shading, which is also known as Gouraud shading, is
     * %   piecewise bilinear; the color in each segment or patch varies linearly
     * %   and interpolates the end or corner values.
     * %
     * %   Faceted shading is flat shading with superimposed black mesh lines.
     * %   This is often the most effective and is the default.
     * %
     * %   SHADING(AX,...) uses axes AX instead of the current axes.
     * %
     * %   SHADING is an M-file that sets the EdgeColor and FaceColor properties
     * %   of all SURFACE objects in the current axes. It sets them to the
     * %   correct values that depend upon whether the SURFACE objects are
     * %   representing meshes or surfaces.
