discover_horizontal_shells() fron Perl to C++, where
the already calculated bridge direction was being lost.
Improved constness of the debug methods
void export_region_slices_to_svg(const char *path) const;
void export_region_fill_surfaces_to_svg(const char *path) const;
Added UNUSED macro to libslic3r.h, used it to reduce some compile warnings.
Split the Int128 class from Clipper library to a separate file,
extended Int128 with intrinsic types wherever possible for performance,
added new geometric predicates.
Added a draft of new FillRectilinear3, which should reduce overfill near the perimeters in the future.
When extruding supports, the support is interleaved with interface
if possible (when extruded with the same extruder).
Otherwise the base is extruded first.
Don't merge classified pieces of layerm->slices, but use the non-split
islands of a layer. For a single region print, these shall be equal.
Added Slic3r-console.ico windows icon for the console Slic3r.
This is a copy of the big icon, with the big images stripped off.
These could be calculated from the fill areas if needed.
On the other side, the non-classified (non-split) fill areas are stored
now for use in the "ensure vertical wall thickness" feature,
also the non-split fill areas are re-used when recalculating the infills.
This is safer than trying to stitch the fill region together from the
classified fragments.
Modified the "ensure vertical wall thickness" feature to use the non-split
fill areas instead of perimeter areas for the calculation
of non-supported regions. This is cheaper as the fill areas contain
roughly half the edges.
Fixed some cracks in the fill surfaces created by rounding all surfaces inside detect_surface_type().

Bridging-Angle not optimal
Extended the "Ensure veritcal wall thickness" mode (merged with the original discover_horizontal_shells function), but this a work in progress. Already Slic3r with "ensure vertical wall thickness" produces less spurious infills inside solids.
Removed dependency on Perl Math::PlanePath module.
Fixed compilation with Visual Studio and SLIC3R_DEBUG: Visual Studio older than 2015 does not support the prinf type specifier %zu. Use %Iu instead.
C++11 move semantics enabled.
