🚧 Ticks

The editor drives animated content through an internal render loop and a pluggable playback clock; it does not expose a general per-frame "tick" callback for application code.

Rendering is scheduled on requestAnimationFrame: the editor coalesces changes and repaints once per frame. When the scene contains animated content (e.g. a GIF), a self-terminating rAF loop keeps repainting while any shape is playing, and the editor stops it when the tab is hidden to save decode and render work.

Playback timing flows through an AnimationClock — a function (shape) => number (ms), defaulting to performance.now(). Replace the process-global fallback with setAnimationClock for deterministic playback (tests, headless export of a specific frame, syncing several shapes); per renderScene call, RenderSceneOptions.clock takes precedence.

import { setAnimationClock, resetAnimationClock } from "@oh-just-another/renderer-core";

setAnimationClock((shape) => myTimeline.positionFor(shape.id)); // ms
// ...
resetAnimationClock(); // restore wall-clock playback

Animated sources are decoded by adapters registered with registerAnimationAdapter (from @oh-just-another/renderer-core, re-exported by @oh-just-another/editor); <Editor> installs a GIF adapter by default. See the animation page for the adapter API.

Planned — not yet available: a public editor.on("tick", …) event that fires once per animation frame for arbitrary host logic. Today the frame loop is internal; drive your own animations via the clock above or your framework's own loop.
