[Gimp-developer] some functions missing from procedure browser

[ian martins <ianxm jhu edu>]

I'm using gimp 2.10.18. Most functions are easily found in the
procedure browser, but some don't appear to be there. I don't see
these:

- Filters>Blur>Median Blur
- Filters>Blur>Mean Curvature Blur
- Colors>Auto>White Balance
- Colors>Tone Mapping>Mantiuk 2006

Are they available to script-fu? If so, how can they be found?
