Why: in v3 the signature for gimp-edit-foo PDB procedures changed to support multilayer selection. This finishes the task for ScriptFu scripts in the GIMP repo. This is not a complete list, since some calls were changed incidentally by prior commits. You can grep for "edit-copy" etc. in script-fu/scripts to find instances. This also makes incidental changes, to script calls to plug-in-tile, which now also has a changed signature to support multilayer. The changes are simple code transformations. The changes to gimp-edit-paste calls are more complex, a mixed bag of a few lines transformed to more lines. I did not try to understand the larger logic of the changed plugins. I did not test the changed plugins functionally. I used a harness to call each changed plugin with improvised parameters, only checking that the test plugin did not throw runtime errors, not checking that they produced correct images. As noted in the issue, this might be undone if the original signatures for gimp-edit-foo are restored as convenience functions.
