Changed the Point3 / Pointf3 to derive from the Eigen Vec3crd / Vec3d.
Replaced the Point::concide_with() method calls with == operator.
Reduced some compiler warnings.
Fixes https://github.com/prusa3d/Slic3r/issues/670
and some of https://github.com/prusa3d/Slic3r/issues/895
PerimeterGenerator was using an unsafe clipper offset function,
which performed offset for both a contour and its holes together.
With this commit the offsets were replaced with their safe counterparts,
though these safe counterparts may be somehow slower
(performing offset on ExPolygon or ExPolygons, piece by piece).
Also there was a bug, where if the infill & gap fill consumed
everything of the polygon, a polygon one onion shell above was still
used for infill.
The problem was caused by the gap fill algorithm, which worked
with square extrusion width values as with rounded extrusion widths,
which sometimes lead to negative extrusion cross sections
for high height to width ratios.
The extrusion width logic has been changed to consider the input width
to be the extrusion spacing, not the extrusion width. The change certainly
removed the negative feed rates, but it also certainly increased the gap
fill width to some exent. It needs to be verified now, whether the gap fill
does not extrude too much.

1x nozzle_dmr for support and top infill,
and 1.125x nozzle_dmr for the rest.
This corresponds roughly to the default values tuned for the Prusa MK2
for normal prints.
When extruding supports, the support is interleaved with interface
if possible (when extruded with the same extruder).
Otherwise the base is extruded first.
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().
Fixed https://github.com/prusa3d/Slic3r/issues/12
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.
into polygons_covered_by_width() and polygons_covered_by_spacing().
Bugfix of ExtrusionLoop::split_at(const Point &point),
where the split ExtrusionPaths were not initialised correctly.
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.
