2.14. On-canvas interaction
           
         
       
      
      GIMP 2.10 ships with a new feature that allows some GEGL-based filters to
      render on-canvas controls. For now, this applies to just three filters:
      Spiral, Supernova, and
      Panorama Projection. But there will be more in the
      future.
