## What's new?
- Implement and test `_window_win32.dart`, the Win32 implementation of
`_window.dart` 🎉
- Wrote a bunch of tests in `window_win32_test.dart` which uses a mock
API barrier to mock the native Win32 layer
- Update `BaseWindowController` to extend `ChangeNotifier` and use it to
inform the `WindowScope` of when things change
- Made `RegularWindowController.empty()` a non-internal constructor, as
it is needed by implementations
- Added a _large_ example application for windowing where users can test
out different windowing concepts and see how they work!
To test, simply run the tests or try out the example app!
