- Make lens not flicker with light level dithering by using
histerisis in threshold.
- Optical nodes always read the past world snapshot for creating
the next snapshot, so there are no accidental fast paths
through optical logic leading to glitches (hopefully).
There seems to be an issue triggering events, so a lot of work
is being done by the abm to cover over this problem...
Much like my earlier work with sz_rotary, I suspect a lot of
fine-tuning will be needed.
