- add a spacing_ratio in flow, but it's only sed for two spacing in perimeter_generator, not sure about the usefulness of it.
- external_perimeter_overlap now use the spacing_ratio to compute
- add perimeter_overlap, using the spacing_ratio to compute
- add perimeter_bonding, that shrink the external-internal spacing, without growing the infill polygons.
better import of 'elephant foot' (spelled elefant in prusa) that is now first_layer_size_compensation, using 'legacy to amke the convert.
advantage: it reverse the sign now.
drawback : no easy export to prusa.
- now has a setting & a threshold
- when reverse_direction trigger on the external loop, it also trigger for all other loops on this side (so, no more U-turn)
- do not depends on extra_perimeter anymore
- now extra_perimeters split into extra_perimeters (the old useless one) and extra_perimeters_overhangs
- reordering settings in the tab.
also some merge for creality printers, and fix some problem in it.
relax the min/max version for the profile, i don't have the resource to check & modify these for each release.
Also some option to only apply to hole (or others)
Also some fixes to some loops options in the codepath.
also a test to thin walls, suspected a bug but can't find it.
