//! KAS, the toolKit Abstraction Library
//!
//! KAS is a GUI library. This crate provides the following:
//!
//! -   a widget model: [`WidgetCore`], [`WidgetConfig`], [`Layout`],
//!     [`Widget`], [`event::Handler`] traits
//! -   a [`layout`] engine (mostly configured through [`macros`])
//! -   a modular [`draw`] API
//! -   widget [`event`] handling
//! -   some data types: [`geom`], [`Align`], [`Direction`]
//! -   some pre-build widgets: [`widget`] module
//!
//! See also these external crates:
