[mkgmap-dev] New code for splitting polygon

Hi Gerd I've written some new code for splitting polygons in an efficient manner. The main interface takes a shape and line of latitude or longitude and returns 2 lists of shapes on either side of the line. There is also a function to clip to rectangle. I've put the code in util/ShapeSplitter but it could go elsewhere if you prefer. So far I've only converted build/MapArea to use it, but I think it can be used throughout eventually. For the moment I've commented out the old code in MapArea, but this can be deleted in a while. Regards Ticker
