1) Using boost::preprocessor to reduce code duplicities when defining
new configuration values.
2) Implemented static hash() and operator== on StaticPrintConfig derived
classes to support hash tables of instances thereof.
Adjustment of GUI/3DBed.cpp,hpp to use the more stable triangulation algoritm
derived from SGI glut.
Fix of an extremely slow bridging calculation, caused by an extremely
slow bridged area detection function, of which the results were never used.
Fixes "slicing fails or takes too long #5974"
This is a fix of a bug, which was in Slic3r forever, where raw slices
were not cached, but recalculated from classified regions, where
merging the regions did not produce the original contour reliably.
Fixes [2.3.0-beta2] Odd bad slicing related to infill (?) percentage #5407
(non-spiral vase layers) were being closed.
Fixes Bad slicing in vase mode (unexpected bridge and solid infill layers) #3326
Fixes Model with holes in the base does not slice properly in "Vase Mode" #5359
1) New algorithm for connecting along the perimeters is now applied
to Honeycomb, Hilbert and similar planar filling curves.
2) The old expensive path chaining is not applied if the new algorithm
to connect along the perimeter lines is called afterwards.
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".
