Cargo features

OS backends follow target_os (no empty Cargo feature toggles). Optional features:

• linux (default) — gtk + x11rb for _NET_WM_WINDOW_TYPE_DESKTOP pin
• rasterize — SVG→PNG data-URI for Adaptive Cards chart/canvas/gauge (pulls resvg)
• workerw — Windows wallpaper WorkerW parenting
• layer-shell — Wayland gtk-layer-shell Background (requires linux)
• macos-private-api — transparent macOS desktop widget webviews (also enable Tauri macosPrivateApi in conf)
• schema / codegen — JSON Schema / TS codegen tooling (dev)

# Default (linux pin enabled; other OS via target_os)

tauri-plugin-widgets = { version = "0.4", default-features = false }

# Windows Widgets Board with chart rasterization
tauri-plugin-widgets = { version = "0.4", default-features = false, features = ["rasterize"] }
