egui changelog

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.
• Response::clicked_by will no longer be true if clicked with keyboard. Use Response::clicked instead.
• Memory::focus has been renamed Memory::focused
• Area::new now takes an Id by argument #4115
• Change the definition of clicked_by #4192
