Bear in mind that the analysis only has to be done once. Once you have the data on how the geometry of two figures relates, you then build up a table of pixel-to-pixel conversions - actually polygons. Copyright wouldn't be an issue. Each module in UTC just tells the program that on a 1000x1000 map, the polygon 333,345-338,342-334,338 needs to be transformed to 611,615-617,620-616,622 or whatever.
