TYPE: COP
TITLE: Sharpen COP

This operation sharpens an image by enhancing the contrast of edges. Increasing
the size of the blur kernel reduces the pixel noise that a sharpen operation
enhances. The Noise Suppress parameter can also be used to ignore false edges,
which can give the image a grainy look.

Parameters
    Size              - Increases the size of the areas over which it performs 
                        the sharpen (in pixels).
    Effect            - Intensity of the shapen effect.
    Noise Suppress    - If on, image noise is not sharpened. Noise is any edge
                        that has a smaller magnitude than the Noise Suppress 
                        value. This produces clearer images.

    Suppress Function - Determines how noise in the Suppress Blend range is
                        sharpened:

	Sharp Cutoff - No blend region is used. 
        Linear       - Sharpening is uniformly reduced.
        Ease In      - Sharpening is gradually reduced.
        Ease Out     - Sharpening is quickly reduced.
        Ease In Ease Out - Similar to linear but using a smoother function.
        Gaussian     - Similar to Ease In Ease Out, with a quicker dropoff.

    Suppress Blend   - The size of the blend region between full sharpening
                       and no sharpening. This prevents "patches" of sharp
                       areas in the image by blending the patches in.
    Show Edges       - Sharpens all the edges, while removing non-edge 
                       components.
