## Break Changes
- The `Scrollbar` has been removed `entity_id` and `scroll_size`
argument from new method, it will get that value from `scroll_handle`.
- There still have a `scroll_size` optional method, if you want to give
your own.
- Also changed the `scroll_state`, `scroll_handle` to receive a ref.
```diff
- Scrollbar::vertical(entity_id, scroll_state, scroll_handle, scroll_size);
+ Scrollbar::vertical(&scroll_state, &scroll_handle);
+ Scrollbar::vertical(&scroll_state, &scroll_handle).scroll_size(scroll_size);
```
- Fix Input, NumberInput padding x with prefix, suffix.
- Fix Input mask char to render in vertical center.
