KAS GUI

KAS is a stateful, pure-Rust GUI toolkit supporting:

• Mostly declarative UI descriptions
• Stateful widgets (e.g. selection range or a pure-UI counter)
• Virtual scrolling (list or matrix), including support for external data sources
• Theme abstraction including theme-driven animations and sizing
• Multiple renderer backends
• Integrated i18n support
• Accessibility tool integration
• Platform integration: persistent configuration, theme discovery, external menus, IME
• Most of the basics you'd expect: complex text, fractional scaling, automatic margins
• Extremely fast, monolithic binaries
