## About The Pull Request
Adds support to underlays to realize_overlays
Ensures decals properly handle plane offsets
Fixes space lighting double applying if it's changeturf'd into. this
will be important later
Makes solar vis_contents block emissives as expected
Moves transit tube overlays to update_overlays, adds emissive blockers
to them
#### Adds render steps
An expansion on render_target based emissive blockers.
They allow us to hijack an object's appearance and draw it somewhere
else, or even modify it, THEN draw it somewhere else.
They chain quite nicely
Fixes shuttles deleting z holder objects
#### Makes space emissive, makes walls and floors block emissives
The core idea here goes like this:
We make space glow, and give its overlays some color
This way, the tile and space parallax remain fullbright, along with
anything that doesn't block emissives, but anything that does block
emissives will instead get shaded the color of starlight
This requires a bit of extra work, see later
This is done automatically with render relays, which now support
specifiying layer and color (Need to make an editor for these one of
these days)
The emissive blocking floor stuff requires making a second render plate
to prevent double scaling
Also adds some new layering defines for lighting, and ensures all turf
lights have a layer. We'll get to this soon
#### Makes things in space blue
We color them the same as starlight, by taking advantage of space being
emissive
This means that things in space that block emissive will block it
correctly and be colored blue by the light overlay, but space itself
will remain fullbright
This does require redefining what always_lit means, but nothing but
cordons use that so it's fineee
#### Makes glass above space glow, and some other stuff
Glass tiles that sit above space will now shine light with matching
color to the glasses color. This includes mat tiles.
Glass tiles (not mat because they have no alpha) also only partially
block emissives.
Adds a new proc that uses render steps to acomplish this, essentially
we're cutting out bits below X alpha and drawing what remains as an
emissive.
#### Modifies partial space showing to support glow
Essentially, alongside displaying space as an underlay, we also display
a light overlay colored like starlight.
That starlight overlay gets masked to only be visible in bits that do
not contain any alpha.
We also mask the turf lighting to not go into bits that have no alpha,
to ensure we get the effect we want.
This is done with that lighting layer thing I mentioned earlier.
#### Makes appearance realization's list output ordered
I want it output in order of overlay, sub overlay suboverlay, next
overlay
Need to use insert for that
## Why It's Good For The Game
Pretty!
Also having space be emissive is a very very good way to test for fucked
emissive blockers (If it's broken why are we even drawing the overlay)
I know for a fact mob blockers on lizards and socks are kinda yorked, I
think there's more

## Changelog
<!-- If your PR modifies aspects of the game that can be concretely
observed by players or admins you should add a changelog. If your change
does NOT meet this description, remove this section. Be sure to properly
mark your PRs to prevent unnecessary GBP loss. You can read up on GBP
and it's effects on PRs in the tgstation guides for contributors. Please
note that maintainers freely reserve the right to remove and add tags
should they deem it appropriate. You can attempt to finagle the system
all you want, but it's best to shoot for clear communication right off
the bat. -->
🆑
add: Space now makes things in it starlight faintly blue
fix: Glass floors that display space now properly let space shine
through them, rather then hiding it in the dark
add: Glass floors above space now glow faintly depending on their glass
type

<!-- Both 🆑's are required for the changelog to work! You can put

Rather then remove the light from all tiles, then re-add the light to all tiles, we just go thru each tile and diff the light level from the last value we added to it. (since this is tracked)
This cut the proc calls for updating lights in half.
Lighting objects now default to full brite rather then full dark so shuttles aren't as immersion breaking when they transit.
Made lighting more agressive about clearing empty lists.
