Filters on turfs don't seem to work (as well / at all)

[MrMelbert]

This floor tile has an outline filter and a ray filter, only seen...on some sides

Likewise I made a spell a while back that spawns a wall with a filter applied (it was intended to be a temporary effect until 3/4ths walls were done and I could make a proper animation), and the filter isn't visible at all.

If I had to guess tgstation#84350 would fix this

I do not think this is solvable. walls are composed of overlays drawn on the turfs around them and we can't filter overlays (I think? maybe we can would solve this).
