Inkscape need a certain number a Python modules at runtime.

There is a top level requirements.txt to that contain all the modules that can be installed using the standard mechanism.

The corresponding manifest fragment is python3-requirements.json. It is generated using flatpak-builder-tools.

./pip/flatpak-pip-generator -r PATH_TO/org.inkscape.Inkscape/requirements.txt --runtime org.gnome.Sdk//47 --ignore-installed lxml

This will also take care of the lxml that needs to be force installed. Also the generated file must be patched to add:

            "build-options": {
                "cflags": "-fpermissive"
            },

to the python3-lxml module so that it can be built with gcc 14.

This application requests the following restricted permissions:

• Network access for the extension mamanger: --share=network
• Needs access to all files: --filesystem=host (FIXME?)
• X11: we use --socket=x11 instead of the fallback as it is required for extensions that use tkinter. See #101
