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.
Fixes [2.3.0-beta2] Odd bad slicing related to infill (?) percentage #5407
(non-spiral vase layers) were being closed.
Fixes Bad slicing in vase mode (unexpected bridge and solid infill layers) #3326
Fixes Model with holes in the base does not slice properly in "Vase Mode" #5359
It can go lower than 0.0125 for the perimeters.
It's kept at a minimum of 0.0125 for infill & thinwalls/gapfaill for performance reasons
and to avoid too much artifacts / corners case.
* add brim_ears_detection_length to be able to detect "sharp rounded angles"
* #722 fix brim ear rectilinear pattern going inside part
* disable brim ear on support raft if not solid
Fixed some issues in internal anchors of the Adaptive Cubic infill.
The ugly and dangerous implicit casting operators in Line, MultiPoint,
Polyline and Polygon were made explicit.
* fix the seam object
* fix painting seam that will jump on nearest for no good reason
* change hidden/near/nearer to cost with 2 boxes for setting the costs.
fix preferences
Ironing flag ignored on infill rotate #4937
Ironing does not take effect when you change Top Fill Pattern. #4900
Ironing layer not shown in preview when settings are changed #4510

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)
