Add a Lanczos3 filter
There was a time not long time ago when I used gimp very often. Now after returning after many years I can't find good old resampling filter lanczos3 which I used very extensively. I found that some discussions mentioning removal was caused by developer of No-Halo and Lo-Halo method, which many found weird as adding filter should not interfere with new ones. Now lanczos3 is back in GEGL, nothing is preventing from coming back to gimp. Is this possible?
