 - The `View` now requires `Send + Sync`, to allow accessing or moving views between threads.
   This prevents using `Rc`/`RefCell`, and may require using `Arc`/`Mutex` instead.
   This should eventually open the way for more multi-threaded processing of the view tree.
+- `theme::Style::effects` is now a map from `Effect` to `EffectStatus`.
+- The `Backend` trait was changed:
+    - `print_at` was split into `move_to` and `print`.
+    - `print_at_rep` was removed.
+- Some dependencies were updated:
+    - toml was bumped from 0.5 to 0.8
