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