## About The Pull Request
Instead of passing in an icon as a source to the alpha mask filter, we
can stick a mutable appearance in our overlays list with a render target
set, and use that render target to do our masking. Remember to use "*"
to avoid rendering the crack twice
## Why It's Good For The Game
CPU time
Makes the code compatible with 515.1594+
Few simple changes and one very painful one.
Let's start with the easy:
* puts call behind `LIBCALL` define, so call_ext is properly used in 515
* Adds `NAMEOF_STATIC(_,X)` macro for nameof in static definitions since
src is now invalid there.
* Fixes tgui and devserver. From 515 onward the tmp3333{procid} cache
directory is not appened to base path in browser controls so we don't
check for it in base js and put the dev server dummy window file in
actual directory not the byond root.
* Renames the few things that had /final/ in typepath to ultimate since
final is a new keyword
And the very painful change:
`.proc/whatever` format is no longer valid, so we're replacing it with
new nameof() function. All this wrapped in three new macros.
`PROC_REF(X)`,`TYPE_PROC_REF(TYPE,X)`,`GLOBAL_PROC_REF(X)`. Global is
not actually necessary but if we get nameof that does not allow globals
it would be nice validation.
This is pretty unwieldy but there's no real alternative.
If you notice anything weird in the commits let me know because majority
was done with regex replace.
@tgstation/commit-access Since the .proc/stuff is pretty big change.

ELEMENT_DETACH is **not** a requirement to having `Detach` called.
Detach is always called when the element itself is destroyed.
ELEMENT_DETACH is a flag that when set, makes sure Detach is called when
the atom destroys.
Sometimes you want this, for instance:
```dm
/datum/element/point_of_interest/Detach(datum/target)
SSpoints_of_interest.on_poi_element_removed(target)
return ..()
```
This Detach cleans up a reference that would have hung if target was
destroyed without this being called.
However, most uses of Detach are cleaning up signals. Signals are
automatically cleaned up when something is destroyed. You do not need
ELEMENT_DETACH in this case, and it slows down init. This also includes
somewhat more complex stuff, like removing overlays on the source
object. It's getting deleted anyway, you don't care!
I have removed all uses of ELEMENT_DETACH that seemed superfluous. I
have also renamed it to `ELEMENT_DETACH_ON_HOST_DESTROY` to make its
purpose more clear, as me and a lot of other maintainers misunderstood
what it did,
---
An update to this, ELEMENT_DETACH *is* needed for anything that can
register to a turf, as turfs do not clear their signals on destroy.
Stationary gas tanks have been in a terrible place for a long time, this addresses some of the issues with a more balance focused change coming in a second mapping pr after this one.
Stationary gas tanks have been made constructable and act similarly to canisters in that they can be damaged, repaired, and over-pressurized to explode. Additionally, they can be made with any rigid material and their stats depend on that material. A glass tank is going to have far less pressure capability than one made of plasteel.
In terms of gameplay there are two main differences now: Adjacent stationary tanks will merge together both graphically and with their internal storage. Any port on any of the tanks can access this shared storage. Also stationary tanks no longer magically have many times the volume for gas as the tile it's in, instead they have a pressure cap and a normal amount of volume.
Of interest to coders this pr also adds a generic grouping datum that acts similar to how pipe networks work. It maintains a listing of all adjacent objects whose type falls within a specified filter. In this case it's used for the gas tanks to know of every other tank in the group. I'll be looking into spreading it's usage elsewhere where this can replace existing one off systems.
Some (de)construction:
First a glass tank is constructed which is then immediately damaged by the high pressure in the gas storage that is now shared. After repairing it for a moment another metal tank is built.
