expanded to a grid (the old way) vs.
snug (like the upstream Slic3r, Cura or Ideamaker).
Snug supports suffered from the degeneracies when merging overhang islands
over a large number of layers when projecting the support towers down.
We borrowed the idea & a bit of code from Cura by simplifying the support
polygons by closing the concave cracks, see the smooth_outward() function
and the MutablePolygon class.

If the new support_material_bottom_interface_layers is left at default -1,
then support_material_interface_layers is used for both top and bottom
interface layers.
If support_material_interface_layers == 0, then neither top nor bottom
interface layers are being extruded.
Reworked skirt generator to only generate skirt at non-empty layers
(layers that actually extruder object or support) and to respect minimum
layer height. Skirt generator stops at the first layer where those both
conditions cannot be met.
New config field for switching the support interface pattern between
default (rectilinear for non-soluble interface, concentric for soluble interface),
explicit rectilinear and explicit concentric.
Also the config layer was reworked a bit to reduce some switch statements
on ConfigOptionEnum<> templates.

to influence the 1st layer of raft or support.
Fixes Allow to disable raft under support structures. #3772
Fixes raft is larger than necessary #2568

Fixes Brim destroyed by support aka. Enable supports on top of brim #1156
Fixes Brim Priority/Support on Brim #713
Fixes Phantom Support columns interfere with brim #3396
Fixes false generation of brim when supports are used #3395
This is a work in progress, as the brim generator currently produces
different brim areas from what the support generator expects.
When projecting the horizontal or nearly horizontal support enforcers or blockers
into object layers, the projection may fall on a layer above or below the layer
where it should in case the nearly horizontal support enforcer or blocker
triangles are intersecting the slicing plane of one of the object layers.
Due to numerical issues, projection of the support blocker or
enforcer triangles may not fall to the same side of the slicing plane
as when slicing the object. To make the projection robust, horizontal triangles
are newly projected to both the layer below and above if they are close
to the object slicing plane.
The projection algorithm was originally made for custom supports, so vertical triangles
were not interesting. They are for seam. Instead of rewriting the algorithm and risking
more bugs, the edge case is detected and the triangle is tilted slightly.
When passing a PrintRegionConfig to the slicing back end, zero an infill
density if it is already nearly zero. This avoids an ugly division by
zero in the infill code and it also makes clear to the back end that
we don't want an infill.
Fixing model import of models with nearly degenerate triangles, which
degenerate after transformation (translation or rotation).
There was certainly a bug in PrusaSlicer, however this bug was triggered
mostly by the ASCII STL files generated by OpenSCAD, likely due to insufficient
number of decimal digits when saving an ASCII STL, see
[openscad/openscad] STL export should contain single precision floats (#2651)
Commented out fuzzy_skin_shape for now, the parameter may be used
in the future, but for now we don't want the parameter to be stored
into configuration files.
Based on pull request Experimental fuzzy skin mode #4611 by @etet100
and on CuraEngine implementation of perimeter fuzzyfication
void FffPolygonGenerator::processFuzzyWalls(SliceMeshStorage& mesh)
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.

The following threads are named with this commit:
slic3r_main, slic3r_BackgroundSlicingProcess,
slic3r_tbbpool_xx_yy where xx is a one based index of the TTB thread
and yy is the platform thread ID.
to help with detecting "not changed" event when taking
Undo/Redo snapshot or synchronizing with the back-end.
Converted layer height profile and supports / seam painted areas
to the same timestamp controlled structure.
1) Fixed a wrong offset when extracting infill lines from the octree.
2) Added a variant for testing triangle in a bounding sphere
when buildind the octree. Currently not used as the box test
is more tight.
3) "Bridging infill" regions are now triangulated and used to densify
the octree as well to support the bridging infill correctly.
1) Octree is built directly from the triangle mesh by checking
overlap of a triangle with an octree cell. This shall produce
a tighter octree with less dense cells.
2) The same method is used for both the adaptive / support cubic infill,
where for the support cubic infill the non-overhang triangles are
ignored.
The AABB tree is no more used.
3) Optimized extraction of continuous infill lines in O(1) instead of O(n^2)
1) All slicer's exceptions are now derived from Slic3r::Exception.
2) New exceptions are defined for slicing errors.
3) Exceptions are propagated to the Plater to show.
It remains to modify the slicing back-end to throw the new SlicingError
exceptions instead of std::runtime_error and to show the other exceptions
by a message dialog instead of a notification.
