Incomplete work to improve support material by avoiding thin columns and making sure everything is supported correctly
Reapply perimeter only to support
Refactoring: generate interface and support in different cycles
Bugfix: top layers were not detected correctly, causing overlap of support material and object in some situations where there were contact regions having the same Z as some top regions
Remove jitter and overlaps in interface infill
Enforce some horizontal margin between object and interface/support (contact not affected)
