  bugfix: extrusion per mm to extrusion mm3 per mm is_volumetric set
  bugfix: speed compensation for stable feedrate also changed the extrusion per mm
  bugfix: speed compensation for stable feedrate also changed the extrusion per mm
  bugfix+refactor: extrusion always per mm3
  bugfix: no support for too low models

  Also send infill polygon data to the UI, not just oultines
  Also send line width to the UI along with the polygon's points
  Add support for sending layer height and thickness to the UI
  Properly reset the extrusion amount between slicing tasks.
  Properly initialize extrusion_volume_per_mm variable
