## 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);
```
- Add `mix` method to mix two color.
- Export `ui::theme::*` to crate root, before `use
ui:theme::ActiveTheme` to `use ui::ActiveTheme`.
## Break Changes
- Moved `ui::theme::Colorize` to `ui::Colorize`.
- Merged `ColorExt` to `Colorize`.
- Renamed `to_hex_string` to `to_hex`, `parse_hex_string` to
`parse_hex`.
## Break Changes
- Renamed `DockItemState` to `PanelState`.
- Renamed `DockItemInfo` to `PanelInfo`.
- Update `cx` type from `WindowContext` to `AppContext` for Panel trait
`panel_name` method.
