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.
