TYPE: COP
TITLE: Pixel COP

This operation allows you to specify an expression to modify the pixels of 
image. The expression is applied to each pixel in turn, and can be specified 
separately for each colour component - R, G, B (for color) and Alpha. 
Additionally, four more expressions are provided for generic components, so
that this COP can also be used to affect any plane (ie Point or Normal).

It is the 2D equivalent of the Point SOP.

Parameters
    Use Color & Alpha Expressions, Then Generic - If on, the color and alpha
						  expressions are used for
						  C.r, C.g, C.b and A. Any
						  other plane types use the
						  generic expressions. If
						  off,the Generic expressions
						  are used for all planes.
    Red, Green, Blue, Alpha        - Expressions used exclusively by C.r,
                                     C.g, C.b and A. All other planes use
                                     the generic expressions.
    Component 1-4                  - The generic expressions for all planes.

    C1, C2, C3, C4  - The values of components 1-4 of the cooked plane.

    RS, GS, RS, RS  - The values of color and alpha in the second input.
    CS1,CS2,CS3,CS4 - The values of components 1-4 of the cooked plane
                      int the second input.

    RT, GT, BT, AT  - The values of color and alpha in the third input.
    CT1,CT2,CT3,CT4 - The values of components 1-4 of the cooked plane
                      int the third input.

    U,V             - The uv coordinates of the current pixel (0 to 1).
    X,Y             - The pixel location of the current pixel (0 to res-1)
    CH              - The component (channel) of the current expression 
                      (0 to 3)
