WIP: MutablePolygon - linked list based polygon implementation
allowing rapid insertion and removal of points.
WIP: porting smooth_outward() from Cura.
Working contour offsetting,
skeleton_edges_rough() to detect "important" skeleton edges.
Radius of an inscribed circle along the "important" skeleton edges
changes slowly, therefore these "important" skeleton edges signify
oblong regions possibly needing a gap fill.
Replaced all "unsigned long long" types with uint64_t.
These "new" types better communicate their meaning and they are
guaranteed to behave the same on all platforms & compilers.
limited anchors, while before a full perimeter segment was always
taken if possible.
2) Adapted the line infills (grid, stars, triangles, cubic) to 1).
This also solves a long standing issue of these infills producing
anchors for each sweep direction independently, thus possibly
overlapping and overextruding, which was quite detrimental
in narrow areas.
3) Refactored cubic adaptive infill anchroing algorithm
for performance and clarity.
1) All slicer's exceptions are now derived from Slic3r::Exception.
2) New exceptions are defined for slicing errors.
3) Exceptions are propagated to the Plater to show.
It remains to modify the slicing back-end to throw the new SlicingError
exceptions instead of std::runtime_error and to show the other exceptions
by a message dialog instead of a notification.
Fixed fatal bug with anchors for mini supports
Make the optimization cleaner in support generatior
Much better widening behaviour
Add an optimizer interface and the NLopt implementation into libslic3r
New optimizer based only on nlopt C interfase
Fix build and tests
Completely remove the concept of CompactBridge.
Replace it with Heads having the same back radius as front radius.
Try to apply the same rules for mini supports as in the route_to_model step.
Increased accuracy of bridge_mesh_intersect shot from support points
Refining mini support integration
boost::polygon Voronoi diagram generator by Vojtech.
Fixed Perl bindings on Windows after some "improvement" of the Windows 10
SDK headers, which fail if included from a C++ code using the
extern "C"
clause. Namely, the Windows 10 SDK include for sockets introduces C++ macros
if a "compiled with C++" symbol is provided even if included through
exetrn "C".
