NOTE (Aurora)

Aurora's "Old Crystals" setting, under Clean View, is a port of Old Crystals by
r4wnet (https://github.com/r4wnet/oldcrystals), whose README credits Quelchi for
the idea. The approach is upstream's: register a copy of the entity cutout no
cull pipeline with the PER_FACE_LIGHTING shader define stripped out, and swap it
in for End Crystals only.

Upstream builds its pipeline from RenderPipelines.ENTITY_SNIPPET. Yarn keeps
that snippet and the register method private, so Aurora clones the public
ENTITY_CUTOUT_NO_CULL pipeline field by field instead and drops the define on
the way through. Upstream's /oldcrystals command and its own config file are not
ported: in Aurora it is a setting like any other.
