In the last few weeks of gdext development, the [GDExtension

API][gd-gdextension] breaks in Godot's recently released [4.1

version][gd-godot4-1]. Migration is mostly done, several FFI bugs have been

addressed on the way.

The godot-rust book now [has a "Hello World" tutorial][gd-tutorial] + guides on

compatibility and selecting Godot version.

Noteworthy features:

- Vector swizzling

- Signals with parameters

- Rust-native APIs for Rect2, Aabb, and Plane

- ToVariant/FromVariant derives

- Godot native structures
