//! Keeping a window out of the taskbar, the per-OS backend behind
//! `WindowConfig::skip_taskbar`.
//!
//! | Platform | How |
//! |---|---|
//! | Windows | winit's `with_skip_taskbar`, at creation ([`skip_taskbar_attributes`]) |
//! | X11 | `_NET_WM_STATE_SKIP_TASKBAR` written before the first map ([`skip_taskbar_before_show`]) |
//! | Wayland | nothing: no protocol open to every client asks the compositor for it |
//! | macOS | nothing: the Dock lists applications, not windows |
//!
//! Both halves are called for every window. Each does its platform's part and
//! nothing elsewhere, so a caller needs no `cfg`.
