gpui-box-kit 0.1.0

//! The parts a modal surface and a drawer build from.
//!
//! [`Dialog`](crate::overlay::Dialog) and [`Drawer`](crate::overlay::Drawer)
//! differ in where they sit and how they arrive, not in what they are made of,
//! so the body callback and the two pieces of copy above it live here.
