Function bevy_render::mesh::morph::inherit_weights

pub fn inherit_weights(
    morph_nodes: Query<'_, '_, (&Children, &MorphWeights), (Without<Handle<Mesh>>, Changed<MorphWeights>)>,
    morph_primitives: Query<'_, '_, &mut MeshMorphWeights, With<Handle<Mesh>>>
)

Bevy meshes are gltf primitives, MorphWeights on the bevy node entity should be inherited by children meshes.

Only direct children are updated, to fulfill the expectations of glTF spec.
