* Clipper: Verify range of int32 coordinates on input. Cherry-picked from prusa3d/PrusaSlicer@fa7debf49d Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * ClipperLib: Optimized PointInPolygon() to calculate cross products with int64s instead of doubles. Cherry-picked from prusa3d/PrusaSlicer@9dca8403fe Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * Reworked the ClipperLib / Polygon types to use the tbb::scallable_allocator to better scale on multiple threads. Cherry-picked from prusa3d/PrusaSlicer@9cde96993e Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * use tbb::scallable_allocator for Polygons and ExPolygon::holes to better scale on multiple threads Cherry-picked from prusa3d/PrusaSlicer@b67ad6434d Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * Fixed compilation on GCC and CLang Cherry-picked from prusa3d/PrusaSlicer@b3b44681a9 Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * Remove clipper2 which is not used * Removed shiny profiler from clipperlib Cherry-picked from prusa3d/PrusaSlicer@7e77048593 Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * ClipperLib: Further optimization of memory allocation using scalable_allocator. ClipperLib: SimplifyPolygon() - changed default winding number to positive, added strictly_simple parameter. ClipperUtlis simplify_polygons() - removed "remove_collinear" parameter Cherry-picked from prusa3d/PrusaSlicer@a7e17df25f Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * ClipperLib: emplace_back() instead of push_back(). Cherry-picked from prusa3d/PrusaSlicer@2e150795b1 Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * Fixed issue in a 32bit clipper, where IntersectPoint() checked for the Y coordinate of the calculated intersection point for validity, but the Y coordinate was already rounded to 32bits, thus an overflow may have in rare cases masked invalidity of the result. Cherry-picked from prusa3d/PrusaSlicer@b39c33414f Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * Fixed Vojtech's out of boundary assert in Clipper library. Cherry-picked from prusa3d/PrusaSlicer@0a202dcff3 Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> * Update clipper to 6.4.2. Cherry-picked from prusa3d/PrusaSlicer@b8b3cccb40 Co-authored-by: Lukáš Hejl <hejl.lukas@gmail.com> * Try fix cmake opencv --------- Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com> Co-authored-by: Lukáš Hejl <hejl.lukas@gmail.com>
