Closes the two open issues and lands the pending unreleased batch: - #90: `Sprite { atlas: 1 }` routes esys_sprite through atlas_draw_ex (scale/flip/tint), so cell / cell_span / strip ids of any size draw through the engine sprite-render system. examples/library/sprite_atlas is the pixel-readback regression. - #91: `become` from an @On(Event) listener / global handler / plain function no longer segfaults the compiler; it emits @L_scene_leave() (a dispatch on the live scene id) so the leaving scene's on-exit runs. UI_* handles are readable from any code (widget table built on first use). examples/library/scene_menus covers it. - fix: a windowed `ludicc -o` build that reaches the audio runtime only through the atlas/Assets preload import now links audio.ll + AVFoundation (the audio backend link was gated on a game-level Audio.* call, so any windowed game declaring Sprite failed to link). - the hand-written "Unreleased" CHANGELOG section is converted to changesets under changes/ so `x release` generates it. - plus the batch: engine-driven retained UI + UiClicked event, Overlay phase, TileSkin tilemap-render system, Key.* constants, Font/Ui/File namespaces, Sprite.strip, prefabs, managers, countdown fields, enum-typed machines, layer @Queries, ludic.prefs / ludic.dungeon packages, Ai.seek pathing, Solids.solid2, cursor confine (mode 3) fix, shooter centre-aim fix, reserved-word function diagnostic. Verified: x test (124/124), x test-tools, check-impl, check-vocabulary, check-docs, docs-gen + docs-check, bootstrap-cfree (seed is a fixpoint).

# sprite_atlas.ludic — the engine sprite-render system draws atlas ids (#90).
|
|
# `Sprite { id, atlas: 1 }` marks `id` as a Sprite.cell / Sprite.cell_span sprite
|
|
# (any size, here a 16x32 two-cell character) and esys_sprite routes it through
|
|
# atlas_draw_ex with scale / flip / tint, so the #81 atlas API and the #85 engine
|
|
# sprite system compose. atlas: 0 (the default) keeps `id` a 16x16 table sprite.
|
|
# Verified by pixel readback after one frame.
|
|
#
|
|
# Driven headless by one stdin key ('q' quits after the frame renders).
|
|
# printf 'q' | LUDIC_MODULES=packages bin/ludic examples/library/sprite_atlas.ludic -> 32 1 1 1 0
