Clipper / ClipperUtils:

1) Let Clipper use int32_t for representing its coordinates. This
   reduces memory and allows to skip conversion between Slic3r Polygon
   and Clipper polygon.
2) Disable additional offset before executing the Clipper Offset algorithm.
   We don't see any reason for that and it required 64bit Clipper coordinates,
   which were disabled with 1).
