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".
The offset curve extractor is already quite usable,
though singular cases are still not covered yet
when the offset curve intersects or nearly intersects
a Voronoi vertex.
Removal of the PRINTF_ZU "%zu" Visual Studio printf compatibility macro.
Fixes of a contours self intersection test for collinear segments.
SVG exporter now exports white background, so that the GNOME Eye viewer is usable.
Now the algorithm is very different from the OpenVoronoi implementation
and hopefully it is now correct (save numerical issues, which will be
a big PITA).
BoundingBox constructor will no more throw for empty vector of points.
GMP allowed for Vojtech's fork of boost::polygon Voronoi implementation.
Added libslic3r tests for boost::polygon Voronoi. All Voronoi issues
ever reported on the Internet are captured by the tests. Two issues
reported (the two test cases) are real issues which may influence
PrusaSlicer negatively, namely

Fix compilation on Windows
Fix array subscript out of range error in MarchingSquares
Fix normals of mesh constructed from slices
Improve performance of mesh construction from slices
Refactored Arrange interface: remove the union based BedShapeHint, replace it with proper function overloads
WARN: this commit is only intermediate, it does not compile.
Compensated slices have negative orientation...
Move efc to common params
Fix elefant foot compensation reversed contours
Remove redundant assertions and don't apply absolute correction if zero
by the PlaceholderParser.
Namely, all the options with the "ratio_over" reference are now handled
correctly by the PlaceholderParser with the exception
of the "first_layer_extrusion_width", which overrides speed of extrusions
by their respective extrusion type.
Also the various extrusion widths (extrusion_width, first_layer_extrusion_width,
external_perimeter_extrusion_width etc.) produce the same numbers
as if ran through the back-end, with the assumption of not overriding
layer height by the variable layer height editing tool or layer height
modifiers.

Working but flipped normals with the interior.
Testing on treefrog passed
Oversampling for hollowed mesh should not be less than 3x
Flip back normals after simplify and remove redundant test code.
Implementation of 2-opt pairwise exchange iterative improvement
algorithm with an extension to a chain of segments, where
the chain of segments may get flipped during the exchange operation.
The 2-opt exchange algorithm may be quite slow.
Using a positive curvature estimate to control the strength
of the Elephant foot compensation shall work similarly to
the previous implementation while avoiding pinching off
tiny pieces from the contour.
