TYPE: SOP
TITLE: Stitch SOP

The Stitch operation is used to stretch two curves or surfaces to cover a smooth
area. It can also be used to create certain types of upholstered fabrics 
such as cushions and parachutes.

Parameters:

    Group         - Subset of geometry to stitch.
    Stitch        - Allows stitching of subgroups of N primitives 
                    or patterns of primitives.
    N             - Pattern to stitch.                               /inc
    Direction     - Direction in which stitching occurs.
    Tolerance     - Minimizes modification to the input sources.     /tolerance
    Bias          - Which primitive remains unaffected [0,1].        /bias
    Left/Right UV - Point on left/right primitive to begin/end the stitch.  
                                          /leftuv1 /leftuv2 /rightuv1 /rightuv2
    LR Width      - Width of the right and left segments of the stitch.
		                                            /lrwidth1 /lrwidth2
    Stitch        - Moves a single row from each primitive to coincide.
    Tangent       - Modifies neighbouring rows on each primitive to create 
                    identical slopes
    Sharp partials - Creates sharp corners at the ends of the stitch 
                     when the stitch partially spans a primitive.
    Fixed Intersection - Allows specification of which side of each 
                         slope is modified.
    LR Scale      - Direction and position of the tangential slopes.
                                                            /lrscale1 /lrscale2
