I am implementing antialiasing detection in our comparison service and I need to be able to determine if the pixel is darker or lighter. We can encode this information by using a negative number if the pixel is darker, and a positive number if the pixel is lighter. We don't need this information in other places, so we can use Math.abs to normalize. While I was at it, I switched getDiffPixel over to use colorDeltaChannels, since colorDelta is deprecated for performance reasons.
