## Unreleased
## 0.27.0 - 2024-03-26 - Nicer menus and new hit test logic
The hit test logic (what is the user clicking on?) has been completely rewritten, and should now be much more accurate and helpful.
The hit test and interaction logic is run at the start of the frame, using the widgets rects from the previous frame, but the latest mouse coordinates.
It enabled getting a `Response` for a widget _before_ creating it using `Context::read_response`.
This will in the future unlock more powerful widget styling options.
The new hit test also allows clicking slightly outside a button and still hit it, improving the support for touch screens.
The menus have also been improved so that they both act and feel better, with no change in API.
Included in this is much nicer looking shadows, supporting an offset.

### ⚠️ BREAKING
* `Response::clicked*` and `Response::dragged*` may lock the `Context`, so don't call it from a `Context`-locking closure.
