2.99 ScriptFu: flawed PDB registration for scripts
Symptom: PDB browser shows flawed signatures for PDB procs implemented by ScriptFu. Example is test-sphere.
1. Arg of type GFile says type gcharray
2. Arg of type GimpEnum says type int
3. Limits for float types are missing from descriptions
4. Defaults are wrong in the descriptions
5. SF_OPTION (a combo box with author defined choices) probably needs work
I think the issue is simply incomplete work moving to GIMP 3.
The issue is not just documentation, but prevents ScriptFu enhancement: use GimpProcedureDialog, which works from the registered args (properties) of PDB procs.
ScriptFu functioning is not affected: it keeps its own knowledge of the signatures, and currently rolls its own GUI.
This issue subsumes #6841 (closed)
I am working on it. MR's forthcoming.
