Parameters
This node displays the following controls in the Parameters tab:
xScale, yScale
The number of pixels that the foreground image is offset by the background image.
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
