// Rusting shader packs, version 1: the `#rusting clouds 1` hook. It runs
// right after the sky hook with the same SkyInput and may change the
// background colour; the built-in hook does nothing. With the clouds
// program's `scale` below 1 the file runs as `cloud_layer` in its own
// pass instead (see cloud_layer.frag) and this built-in stays here.
