1) If "support on build plate only" is enabled, the support columns are newly trimmed to not land on top of an object. However this may make the column too small to be stable. 2) Support enforcers newly take precedence over "supports on build plate only" and over "don't support bridges". 3) Some refactoring of the support generator code for clarity: Reduced some of the worst spagetti offenders. Fixes Support generated even if support on build only activated #915 Fixes Bug: supports on build plate only #1340 Fixes Bottom interface layer is not generated , support on build plate only. (long open defect) #4199 Fixes option "supports on build plate only" does not work #3980 Fixes No support interface layers generated #1997 Fixes Feature Request: Option to combine results of 'support from build plate only' and 'support enforcers only' #2801 Fixes Support interface isn't generated: build plate only + blocked by model + support enforcer #3831 Fixes Support Enforcer don't create interface layers #5748 Fixes Support Enforcers Don't Have Top Loops/Raft #1870 Fixes Don't cancel support enforcers with "don't support bridges" #5105
