Offsets an rgb patch based on the alpha position.
Used to remove unwanted areas of an image by copying another section of the same image over the problem area.
To use...
1. draw a RotoPaint shape around the area to be covered (such as a tracking marker on a greenscreen background), making sure the RotoPaint output is set to 'alpha' and 'replace' is on if needed.
2. Connect the image into 'foregroundPlate' and the RotoPaint into 'definingMatte'.
3. Use the Offset controls in the node to move a clean part of the image over the problem area.
