gpui-base 0.9.1

//! A grid whose items the user drags and resizes into place.
//!
//! [`GridLayoutState`] owns the layout — one [`GridArea`] per item, in grid
//! cells — and the rules it settles under; [`GridLayout`] places each
//! [`GridItem`] in its area and turns pointer and keyboard input into layout
//! changes. The pure layout arithmetic lives in `layout`, apart from pixels
//! and entities.
