Resolve WB-769 Surface ID node creates  'notch' in volume/surface contour outline: This problem occurred when the volume slice had the same coordinate as a vertex which causes an intersection problem.  Code to prevent the intersection problem moved the vertex slightly away from the plane and this code was mistakenly assigning the Y value to the Z value causing the 'notch'.
