TYPE: SOP
TITLE: Smooth SOP

The Smooth operation smoothes out (or "relaxes")  polygons, meshes and curves,
without increasing the number of points.  It rearranges the existing points in
the geometry to remove roughness.

Smooth can also smooth floating point attributes that are of size 1, 2 or 3,
including color and texture coordinate.
If there is an ambiguity between using a vertex attribute or a point attribute,
the point attribute is used.

Parameters:

    Group                - Subset of primitives to smooth.
    Apply To             - Apply smoothing operation to point position, texture
                           uv's, color or another attribute specified by name.
    Attribute Name       - Point or vertex attribute to smooth      /attribname
    Cutoff Frequency     - Noise frequency to remove.  The larger this value,
                           the more it will keep the original shape of the 
                           geometry.                                /frequency
    Smoothing Iterations - Number of smoothing steps.               /iterations
