Function mark_dirty_trees

    changed_transforms: Query<'_, '_, Entity, Or<(Changed<Transform>, Changed<ChildOf>, Added<GlobalTransform>)>>,

Available on crate feature bevy-support only.

Optimization for static scenes. Propagates a “dirty bit” up the hierarchy towards ancestors. Transform propagation can ignore entire subtrees of the hierarchy if it encounters an entity without the dirty bit.
