TYPE: COP
TITLE: Vector COP

This operation performs vector operations on the input. The input planes
are considered to be arbitrary vectors (either 2, 3 or 4 elements). Scalar
planes (like alpha) are treated like 1 element vectors.

Parameters
Vector
    Operation         - Specifies the operation to perform.
	Normalize Vectors - Scales all components so the magnitude
                            is exactly 1.
	Transform Points  - Transforms the vectors as if they were
                            points by the following Transform
                            parameters.
	Orient Vectors    - Rotates the vectors as if they were 
                            normals.

    Transform (Order, Translate, Rotate, Pivot, Uniform Scale) - Defines the
								 transformation
								 for transforming
								 the vectors.
