* change to new fog system
* Fix fog conversion issues
* remove unused old neb values
* Update scripting API
* temporary old-value round trip
* Rewrite nebula fog with four explicit parameters
Replace the legacy `+Fog Near Mult` / `+Fog Far Mult` model — which
depended on fixed engine constants — with four parameters that map
directly to renderer behavior:
+Fog 1000m Visibility fraction of light surviving 1000m of fog
+Fog Near Distance meters from camera where fog begins
+Fog Skybox Clip Distance max render distance for the skybox in fog
+Fog Clip Distance max render distance for the scene in fog
The deferred-lighting fog shader, material system, model renderer,
object sort, and the Lua mission API all consume the new parameters
directly. The legacy `Neb2_fog_near_mult` / `Neb2_fog_far_mult`
globals are removed.
Mission parsing accepts either the legacy keys or the modern keys.
Legacy values are converted to the modern set at parse time, and a
per-mission flag (`Neb2_fog_use_legacy_values`) records which keys to
write back on save. The flag is cleared only when something actually
changes, so opening and OK'ing an unmodified legacy mission preserves
its on-disk format. Saving uses `optional_string_fred` to preserve
user comments through edit cycles.
FRED2 and QtFRED background editors both expose the four parameters
in place of the old multipliers, with friendly labels and tooltips.
Both editors validate input (visibility clamped to [0, 1]; near
distance must be > 0; skybox and scene clip distances may be 0 to
disable fog at that range) and use a snapshot-and-compare at close
time so that a no-op open-then-OK never spuriously rewrites a legacy
mission in the modern format.
FRED2's background dialog is also reorganized so that "Display bg
bitmaps in nebula", "Override nebula fog palette", the RGB row, and
the four fog parameters all sit inside the Nebula group box; the
"Old Nebula" group box is restored below it with its Pattern, Color,
Pitch, Bank, and Heading controls back inside the frame. The dialog
now overrides PreTranslateMessage so that the new fog tooltips —
and the previously broken "Save sun/bitmap angles in correct format"
tooltip — actually fire.
QtFRED's BackgroundEditor.ui adds four QDoubleSpinBox controls in
the existing nebula form layout, with per-field decimals chosen to
avoid scientific notation, and per-field min/max declaring the
validation rules. The QtFRED help page is updated to describe the
new fields.

- Rename Neb2_fog_use_legacy_values to Neb2_fog_save_legacy_values
to reflect that the flag governs save format, not runtime
behavior.
- Decide both the save flag and the legacy-to-modern conversion
purely from whether the file contains modern fog keys, dropping
the prior heuristic based on required_fso_version. A mission
without modern keys (legacy- or retail-format) converts on load
and saves back in legacy format; missions with modern keys are
saved as modern.
- Snapshot the four fog values as floats at editor open and use
fl_equal for the no-change comparison in both FRED2 and QtFRED,
replacing the FRED2 CString comparison and the QtFRED strict
inequality.
- Document the on-disk invariant in missionsave: when not saving
legacy keys, the four modern keys must always be written (never
gated on "only if non-default"), since the parser uses their
presence to decide whether to run the conversion on next load.

Add coverity[GLOBAL_INIT_ORDER] annotations to ~50 global variables
across 27 files. These were all analyzed and confirmed safe:
- ~48 OptionBuilder::finish() globals use a Meyers singleton
(OptionsManager::instance()), which guarantees safe init order.
Destruction is also safe due to shared_ptr ref-counting.
- 6 default-constructed container globals (vectors, maps) have no
cross-TU dependencies at construction or destruction time.

For type safety, use enum class rather than int.
Also make a few miscellaneous tweaks such as adding a new casting macro and making detail level settings a bit cleaner.
1. Add new SEXP operators for setting and fading poofs that will work with one or more arguments, or no arguments (which will affect all poofs at once).
2. Update SEXP help, including clarification that the three `nebula-change-` operators require a nebula to be active to have any effect.
* Removing block to allow volumetric and background nebulas to render at the same time
* Updating code from feedback on pull request #6853
* What the... did I miss a line?
* Dual fog layering should now work when both nebula types are active
This allows the first half of a modular -neb.tbm to be skipped, allowing just poofs to be specified without the need for a preceding empty bitmap section. It's a follow-up to #5128 which allowed just bitmaps to be specified without the need for a subsequent empty poof section.
Most places in the code that use `vm_vector_2_matrix` do so on already-normalized vectors. Changing these to `vm_vector_2_matrix_norm` avoids redundant normalization.

In `strings.tbl` the graphics settings localization IDs are as follows:
1160, "Low"
1161, "Medium"
1162, "High"
1163, "Very High"
These values are used throughout the code, but in some cases with SCPUI upgrades, the IDs got off by 1. This PR fixes those incorrect IDs.
* Create the ingame options game state
* Base working version of in-game options

* Respect time compression
* Fix sexp description
* Make sure faded poofs do not flicker
* optimize
The `SCP_string_lcase_equal_to()()` and `SCP_string_lcase_less_than()()` functors are rather unwieldy to use in non-functor situations, so this adds conventional function equivalents.
Gather all the mission initialization code into a common function for clarity and ease of expansion. Previously, the various parsing routines contained initialization as well as parsing. As a bonus, quite a few redundant initializations are streamlined.
* implement modular nebula.tbl
* Address feedback and skip > 32 poofs
* read/write nebula poofs by name
* qtfred changes
* variable name
* log -> warning
* nullptr and make sure to only set bitmap_name when it's actually defined
