Transform: Pan, Zoom & Rotate

Support pinch and multi-touch gestures.

Pinch, Zoom, Rotate

Some gestures use two fingers at once. Compose bundles pan, zoom, and rotate into a single helper called detectTransformGestures. 🤏

Inside pointerInput, detectTransformGestures hands you pan as an Offset, zoom as a Float scale, and rotation in degrees together.

detectTransformGestures { _, pan, zoom, rotation -> }
