TYPE: COP
TITLE: Mono COP

This operation converts a color or vector into a scalar quantity, like
luminance or length. Optionally, vector planes can be converted to scalar
planes.

Parameters:
Mono
    Operation                     - How to convert the color or vector to a
                                    scalar.
    Keep Vector Planes as Vectors - If on, vector planes are not converted to 
                                    scalar planes.
