Hello,

Compared to 2.9.22, this commit was dropped:
| Changeset: 923
| Branch: libpano13-2.9.22
| User: tmodes
| Date: Mon Jul 31 17:21:40 CEST 2023
| Tags: 2.9.22
| Parent: 921:ad7616ee8c26 (Correctly initialize variable)
|
| Replaced ShowScript and LauncAndSendScript functions with non-functional
| stub
|
| These function are not used by libpano itself and have security issues.
| Provide for now a stub with a message to stdout to keep the ABI constant.
|
| They will be removed completety in the next version.

If that is intentional (as the commit message says) the soname needs to
be bumped.

Is bumping the soname really necessary? Nothing ever used these two
functions. So now they are removed completely, does this change the
ABI in any practical way?

For example: if I downgrade to an earlier hugin package that was
linked to 2.9.22, it seems to be ok with the new 2.9.23 library.
