A significant amount of influence was taken from
https://github.com/Baystation12/Baystation12/pull/33255, however adapted
to Aurora. Key things to note is the port of the newer alpha settings
from /tg/, among other improvements.
The ancient holographic and screen overlay code has been purged. This is
now handled with emissives, while holograms are handled with filters as
well.
