- CompositeCollider2D combines its members in composite order (equal orders keep hierarchy order), each by its Collider2D.compositeOperation on what the ones before made: Merge (union), Intersect, Difference and Flip (exclusive or), through i_overlay's boolean operations in the native host; the first member is taken as it is, whatever its operation, as in Unity. Changing an operation or order rebuilds the composite.
- Checked by
composite_operations(6000.3): each operation, first members, orders, a chain of all four, and an operation changed at runtime, by path count, signed area, bounds and which points are inside. - Next: the window icon; UI Toolkit's remaining pieces (TextField, sliders and scrollers, rounded corners, transitions); CompositeCollider2D.offsetDistance.
