//! POD types for the screen-capture surface

//! (SUPER_PLAN_2 §4 Priority 6 + research/01).

//!

//! Symmetric to the camera surface: screen capture is a "dumb widget"

//! (`azul_layout::widgets::screencap::ScreenCaptureWidget`) that owns a

//! background capture thread + a GL-texture `ImageRef`, identical to the

//! camera widget — only the *source* differs (a display / window instead of

//! a camera). Defined here in `azul-core` so the config types cross the FFI

//! without `azul-layout` (or ScreenCaptureKit / MediaProjection / PipeWire)

//! as a dependency.

//!

//! Reuses the camera surface's generic capture status types

//! ([`crate::camera::StreamState`], `CaptureStats`, `CaptureStreamId`,

//! `CaptureErrorCode`) — those are capture-agnostic.
