#13425: bug in boost polygon resize

------------------------------+---------------------
 The function:

 void handleResizingEdge45() in polygon_45_set_data.hpp:943

 When resizing a vertical/horizontal edge, the code construct a
 rectangle_data<int> directly instead of using Unit template. When the
 coordinate_traits<int64_t> is specialized, this easily causes the integer
 overflow and lead to bogus result.

 Change int to Unit would be the simple fix.

 Thanks,
