Gaphas

Changes

* Fix segment disconnect: after a reconnect the right handle and port should be referenced.

For this to work the disconnect callback interface has been changed from `callback()` to `callback(item, handle, connected, port)`.

Changes

- Drop Python 3.8 support
- Add Python 3.11 support
- Deprecate `gaphas.util, `scroll_tool` and `pan_tool`
- Update Poetry to 1.2 (474)

🐛 Bug Fixes

- Fix scrolling (481)

🧰 Maintenance

- Add permissions for pr-labeler and release-drafter (433)

Changes

- Negative distance amolenaar (413)

Changes

* Add horizontal scrolling with `Shift`+`ScrollWheel`.

Changes

- Integrate line segments, `segment_tool` is history (380)
- `gaphas.connector` is split in `gaphas.handle` and `gaphas.port`
- Moved `gaphas.aspect module` to `gaphas` package
- Moved `gaphas.view.model` to `gaphas` package

This cleanup should reduce the chance of requiring GTK, which is a huge benefit for, for example, the Sphinx extension in Gaphor.
