reserving to much memory inPolygon::GetCoordinates

[jaapdekker]

A length error exception is thrown when Polygon.GetCoordinates() is called with a polygon(sea area around Scotland) with 1396535 coordinates where the shell has size 411057 and that contains 7998 holes (Islands in the sea) the error is caused in Polygon.cpp where a reserve is done with the wrong size the error is on line 123 in Polygon.cpp

npts=shellCoords->getSize();

/*

• reserve space in the vector as if all holes have the same
• amount of points. Holes usually have less, so this should
• be a good compromise */

cl->reserve((nholes+1)*npts);

causing 3,287,633,886 Coordinates to be allocated
