[Gimp-print-devel] Documentation Build Patch to 10-04-2024 version

[Erik B. of T. <ba...@ta...>]

Hi all,

Attached is a little patch to fix some documentation build issues.

In particular, it removes long-obsolete command tests that don't
actually do anything but give warning messages (openjade and related).

It also cleans up and updates the two .dox.in files, removing the long
unsupported a4wide option and updating other items to modern dox file
requirements.

Regards,

Erik
