xDOffset, yDOffset
A panning factor applied to the image. Intensity is usually 0 to 1; 1 is 100 percent of the
x/yScale factor.
xChannel, yChannel
The channel from the background image that is used to distort the foreground image.
xDelta, yDelta
The anticipated distance the pixels will move. If this value is too high, calculations slow
