26  * A sample of a pixel operation. Pixel operations are those OPs which use the
27  * values from their plane and pixel location only to determine the output. For
28  * example, HSV and Gamma are Pixel Operations, whereas Blur (since it accesses
29  * neighbouring pixels) and Premultiply (since it requires both color and alpha
30  * planes) are not.
31  *
32  * Pixel Operations, when placed in series, are combined into 1 operation.
