Greg Pomerantz d990627200 gtauri: distance-from-viewport drop policy for ALL jobs 
The backlog must never delay on-screen work. Urgent jobs (real
Chromium requests) are now stale-dropped too, not just prefetch:
a fast fling queues urgent work for every band it crosses, and all
of it except the final band is dead — it filled the queue cap and
made fresh on-screen requests wait for the JS retry timer.

Safe because the anchor now settles at the final scroll position
(trailing send), and on-screen cells have idx >= VPORT so they can
never be dropped. A pure LIFO would not fix this: stale jobs sit
at the stack bottom, never popped, still blocking the cap.

Emulator fling test: 309 stale urgent jobs purged, queue peak 28,
all 850 decodable images loaded.

README.md

gallery

A high-performance image gallery for Android (primary), Linux and macOS — Rust + egui 0.31 (egui_glow / winit 0.30 / glow 0.16). Ported from Slint 1.18 after the zero-jank campaign showed Slint-on-Mali janky at its base level while egui measured 3–7× cleaner (HANDOFF.md §8.11–8.12). The Slint tree is preserved in git history and docs/BUGS/.

Status: M0–M4 ported to egui, zero-jank tuning in progress. See HANDOFF.md — the development hand-off: architecture, thumbnail pipeline, milestones M1–M7, the Slint jank campaign, the egui port, and the sltest/egtest/tttest harnesses (A/B/C: Slint/egui/WebView).

Build

./scripts/build.sh debug     # debug x86_64 APK + install on emulator
./scripts/build.sh           # release x86_64 (emulator)
./scripts/build.sh aarch64   # release aarch64 (device)
cargo run                    # desktop (Linux needs libfontconfig1 + pkg-config)

Requires: Rust (rustup), cargo-apk2, Android SDK + NDK 27 (see HANDOFF.md §3 for exact paths/env).
