Out current appimage build scripts are outdated. They should use linuxdeployqt:
- We also should build appimages for gmic-qt and ffmpeg: these two executables are shelled out to from Krita
- We should decide whether to ship those inside the krita appimage, or as separate downloads, or together with the krita appimage in a zipfile.
- The appimage should also include python
- The appimage should include QtMultimedia, gestreamer and the gestreamer plugins
