//! The iTerm2 inline-image encoder: a PNG inside an OSC 1337 escape.
//!
//! `width`/`height` are given in cells, pinning the image to the exact cell box
//! the layout reserved — the terminal scales if its real cell geometry differs
//! from the configured one, so chrome and panel can never drift apart.
//! `doNotMoveCursor=1` leaves the cursor where the image began: the renderer
//! restores its saved position afterwards anyway, and an image that ended at
//! the screen's bottom row would otherwise scroll the screen first and put
//! that restored position one row off.
