inside ClipperUtils are now using bit shifts instead of multiplication
by doubles, which makes the scaling precise.
Removed the scale parameter from all offset functions.
Modified the safety offset to calculate offset per polygon instead
of over all polygons at once. The old way was not safe and very slow,
sometimes this meant a kiss of death for supports for example.
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.
slightly by inflating the projected top/bottom/bottom bridge surfaces
before they are added into a surface. This ensures, that the possible
projected infill areas merge with the perimeter supporting areas,
but the perimeter supporting areas will not be inflated on their own,
if there is no touching projection of a top/bottom/bottom bridge
surface.
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.
are thick enough to be actually filled by the rectilinear fill.
Otherwise gaps would be left in the sparse infill, causing missing
bond to the perimeters.
Added a safe variant of offset(const Slic3r::ExPolygon...), which offsets each loop separately.
New functions "remove_sticks" to remove zero area parts of polygons.
New functions "remove_small" and "remove_degenerate" for polygon clean up.
Extended the C++ supports, those are not finalized yet though.
Also a bug has been fixed for zero interface layers. Before
slic3r would put infinite number of interface layers over top surfaces,
if the number of interface layers was set to zero.
