### Added
- Server module
- Change collector
- Customizable accessors for colors
### Changed
- Vision does not implement ItemProvider anymore. Property changes are done via `getProperty`/`setProperty` and `property` delegate.
- Point3D and Point2D are made separate classes instead of expect/actual (to split up different engines.
- JavaFX support moved to a separate module
- Threejs support moved to a separate module
- \[Breaking change!\] Stylesheets are moved into properties under `@stylesheet` key
- \[Format breaking change!\] Stylesheets are moved into properties under `@stylesheet` key
### Deprecated
