Minor error causing support material to fail when first_layer_height was expressed in % (caught by regression test). #1371
Fix wrong slices when many overlapping facets were present in the model
Fix collision detection for brim
New --first-layer-acceleration option
Require --default-acceleration when other acceleration settings are used
Adjust collision detection for brim and include support islands inside the only_retract_when_crossing_perimeters logic
Fix regression causing too much collapsing of infill regions
Adapt avoid_crossing_perimeters code to the recent changes
Offset projection of facets before the final union
Simplify layer change code now that we have distinct support layers
Added some debugging code
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)
Make sure teeth are not too tight
Fix regression causing lack of contact infill
Bugfix: alignment code for rectilinear infill caused lack of infill (regression in 948b43f). #1387
