1) Flipped the order of "discover_vertical_shells" and "process_external_surfaces",
now the external surfaces are expanded after "discover_vertical_shells"
aka "ensure vertical wall thickness" is solved.
2) Reworked LayerRegion::process_external_surfaces() to only expand into
"ensure vertical wall thickness" regions, also the expansion is done
in small steps to avoid overflowing into neighbor regions.
also:
Utility functions reserve_more(), reserve_power_of_2(), reserve_more_power_of_2()
Various SurfaceCollecion::filter_xxx() modified to accept an initializer list of surface types.
New bridges detector refactored to accept overhang boundaries.
BoundingBoxWrapper was moved from RetractCrossingPerimeters to AABBTreeIndirect.
1) New region expansion code to propagate wave from a boundary
of a region inside of it.
2) get_extents() extended with a template attribute to work with
zero area data sets.
3) ClipperZUtils.hpp for handling Clipper operation with Z coordinate
(for source contour identification)
Fixes Slicing slows or hangs on "Generating Permiters 20%" cpu load is at 100% #8164
Fixes Slicing hangs on generating perimeters with thing:3565827 (30g) #3259
New step - estimation of curling on both the model and the support extrusions.
Improvements in curled filament estimation algortihm
Implementation of Jump Point Search algorithm
Use of JPS algorithm to avoid curled extrusions during travel moves in Gcode export
That allows computed better values in cases when the extrusion width of the first layer or for the infill differs from the extrusion width for perimeters.
Parameters min_feature_size and wall_transition_length now can be set in percentages, and then they will be calculated based on nozzle size. Old profiles with default values are forced to replace old default values with new default values in percentages.
This is the follow-up to 63c66f4f18. Detection of non-planar (degenerated) Voronoi diagrams was rewritten to check if all neighboring edges of the Voronoi vertex are CCW ordered.

We introduced detecting for those degeneration cases. When degenerated Voronoi diagram is detected, then the input polygons are rotated, and the Voronoi diagram is recomputed. Usually, rotation of input data solves issues like this.
