autoitx 0.1.2

//! Clicking a control without pinning the screen resolution.
//!
//! Hand-written AutoIt automation clicks absolute screen coordinates, which is
//! why it also hard-codes a resolution check at startup and refuses to run when
//! the display changes. Anchoring the click to the window removes that: the
//! window can be anywhere, and the offset still lands.
//!
//! ```text
//! cargo run --example anchored_click
//! ```
//!
//! Prints where it *would* click rather than clicking, so it is safe to run.
