Looking at some of the new tweaks in Gimp 2.10 and a non-photographic filter, Filters -> Map -> Panorama-Projection. (It is in Gimp 2.8 as a GEGL operation, but who ever looks there). An additional option Inverse-Transform
The dialogue looks like this, with nice on-canvas updating. WYSIWYG
Why am I writing about this not-very-often-used filter? You might have, once upon a time, used a Gimp plugin MathMap to produce similar results. Will MathMap still work in Gimp 2.10? Yes but you might have to do a little gentle hacking to provide the necessary library files that MathMap requires.
This in a Kubuntu 18 VM and Gimp 2.10 from otto-kesselgulasch/gimp-edge. The mini-planet filter.
