vsync.rs: - set_state(animating, dirty) replaces set_animating. The Choreographer callback chain re-posts while animating||dirty: gating on animating alone let the chain die during flings (pointer inactivity >200ms) — with EW disabled the loop then froze (measured: 30 frames in 4s, then silence). The dirty mirror is pushed every main-loop iteration (<=8ms stale); the 6ms poll backstop bounds chain-break damage. - EW_ON now gates the WAKE itself: the early waker raced the Choreographer (fires at edge+0.52ms measured) and its independent phase caused the -4..+4ms render-phase wander. Choreographer is the single wake source. - MISS lines carry forensics: sw/sn (wake slot vs last rendered slot), eage (ms since last observed vsync edge), lastage (ms since last render) — distinguishes chain-stall / loop-stuck / guard-reject / no-wake-iteration without a second run. stg.rs: - ctxsw_sample() reads /proc/self/task/<pid>/stat for voluntary/involuntary context switches, CONDITIONAL on iteration >5ms (per-iteration procfs reads were a measured confounder: 20-50us each, pushed phase across the slot boundary, 10x worse drops). vsw/nvol on the IT line. - precpu: CPU time inside Queue::present on the PRES line (pre_us >> precpu = blocked on binder/fence/SF; pre_us ~= precpu = CPU-bound). wgpu_30_surface.rs: EW_ON moved here (vkprobe) so vsync.rs can gate the wake without a new crate dependency. lib.rs: poll backstop uses the dirty state; 6ms cap during active phases. |

Slint Android Activity Backend
This crate implements the Android backend/platform for Slint.
It uses the android-activity crate to initialize the app and provide events handling.
It can be used by using functions from the slint::android module
