TYPE: SOP
TITLE: UVUnwrap SOP

UVUnwrap assigns texture UV coordinates to the Source geometry for use in 
texture and bump mapping.

Given a set of planes, this operation will project each input primitive onto
the plane which will cause the least distortion in the shape.  The
planes can either be specified with one of the default sets or else
provided through the second input.

In addition, polygons are grouped into regions which are connected polygons
that map to the same plane.  These regions are then laid out to prevent
regions from overlapping.

Parameters:

    Group           - Subset of geometry to apply texture to.
    Plane Group     - Subset of second input polygons to use as planes.
    Planes          - Default plane orientations.
    Layout          - How to lay the regions out.
    Scale           - Type of scale to apply after the projection and
                      layout.
    Spacing         - Percentage of the laid out space to leave between
                      adjacent regions.	                             /spacing
    Rotate Order    - Order of rotations.
    Rotate          - Rotate angles in degrees                    /rx /ry /rz
