For the feDisplacementMap filter, what is the expected behaviour for 
displacements that are outside the bounds of the input image?

For example, if the calculated displacement for pixel (10,10) ends up 
being (-20,-20), what will be used for P'(10, 10)? Will the original 
pixel be used unchanged, or will it be black, or something else?

Also, is this question answered in the spec already and I missed it?

Best regards,
