- Port based on Baystation's implementation and customized for our code and usages.
- Switched space icon_state permutation to a "dust" overlay that is permutated the same way. As an overlay, the dust can be *above* the parallax planes. Space turfs are now white to allow skybox to BLEND_MULTIPLY onto them.
- Added skybox hud effect that replaces background space turfs with an image moved to create a parallax effect.
- Added skybox subsystem to generate and manage skybox parallax images, and lots of images for it!
Couple minor changes with the substation name and maintenance: secondary command maint/substation now. The SMES, Powernet Sensor, and Breaker Box RCON tags are all renamed accordingly
This commit is for making the copy ready to use for copying over the old version of the Secondary Command, plus the maints and sand outside. The new file will be deleted for the second commit.
Largely ported from the work done at Baystation in https://github.com/Baystation12/Baystation12/pull/17460 and later commits.
- Shuttles no longer require a separate area for each location they jump to.
Instead destinations are indicated by landmark objects, which are not necessarily exclusive to that shuttle.
This means that more than one shuttle could use the same docking port (not at the same time of course).
- Enhanced shuttle control computers to use nanoui if they didn't.
- Organizes shuttle datum code a bit better so there is less re-inventing the wheel in subtypes.
- Allows the possibility of shuttles (or destinations) that start on late-loaded maps.
- Deprecate the "extra" shuttle areas that are no longer needed and update shuttle areas in unit tests
This all required a bit of infrastructure improvements.
- ChangeArea proc, for changing the area of a turf.
- Fixed lighting overlays actually being able to be destroyed.
- Added a few utility macros and procs.
- Added "turf translation" procs which are like move_contents_to but more flexible.
- Replaces remainder of purple walled alien stuff with blue walls
- Fixes some vendors in Mothership resleeving being inaccessible
- Fixes decal issue with Central bathroom
