Previously the vertices directly underneath an airport were displaced downwards. In general this worked OK, but for airports surrounded by higher terrain, this could cause "ridges" from edges from vertices just outside the airport boundary. This commit modifies the algorithm to also reduce the elevation of vertices immediately outside the airport boundary as well.
