Port Z Anti-Aliasing from BambuStudio-ZAA (https://github.com/adob/BambuStudio-ZAA)
to OrcaSlicer. ZAA eliminates stair-stepping on curved and sloped top surfaces
by raycasting each extrusion point against the original 3D mesh and micro-adjusting
Z height to follow the actual surface geometry.
Key changes:
- Add ContourZ.cpp raycasting algorithm (~330 lines)
- Extend geometry with 3D support (Point3, Line3, Polyline3, MultiPoint3)
- Template arc fitting for 2D/3D compatibility
- Change ExtrusionPath::polyline from Polyline to Polyline3
- Add 5 ZAA config options (zaa_enabled, zaa_min_z, etc.)
- Add posContouring pipeline step in PrintObject
- Update GCode writer for 3D coordinate output
- Add ZAA settings UI in Print Settings > Quality
- Add docs/ZAA.md with usage and implementation details
ZAA is opt-in and disabled by default. When disabled, the slicing pipeline
is unchanged.
## Problem
Some Creality printers (e.g. Ender-3 V3 SE) rely on metadata comments in the first lines of G-code files to display print info on the screen (estimated time, filament usage, layer height). This follows a format originally used by Cura/Creality Print:
```
;FLAVOR:Marlin
;TIME:3708.97
;Filament used:6.21m
;Layer height:0.2
```
OrcaSlicer currently has no way to write content before the `HEADER_BLOCK` in the G-code output, and does not expose `print_time_sec` or `filament_length_m` as usable placeholders. As a result, these printers show zeroed-out print info on screen.
## Changes
### 1. New placeholders (post-processing)
Added two new G-code placeholders resolved during post-processing:
- `{print_time_sec}` — total estimated print time in seconds (double)
- `{filament_length_m}` — total filament length in meters (double)
These values are only available after G-code generation, so they use inline marker replacement (`@PRINT_TIME_SEC@`, `@FILAMENT_LENGTH_M@`) that `GCodeProcessor::run_post_process()` substitutes with actual computed values — the same pattern used by existing M73 and layer count placeholders.
### 2. New "File header G-code" option (`machine_top_gcode`)
Added a new G-code field in **Printer Settings > Machine G-code** that writes content at the very top of the output file, before `HEADER_BLOCK_START`. This allows users to add firmware-specific metadata that must appear in the first lines.
### 3. Creality Ender-3 V3 SE profile update
Pre-configured the Ender-3 V3 SE profiles (all 4 nozzle variants) with a default `machine_top_gcode` value matching the Cura-compatible header format, so print info displays correctly out of the box.

## Tests
- Sliced test model with Ender-3 V3 SE profile
- Verified G-code output contains correct values in first lines:
- `;TIME:` with actual print time in seconds
- `;Filament used:` with filament length in meters
- `;Layer height:` with correct layer height
- Verified `{print_time_sec}` and `{filament_length_m}` work in both Machine Start G-code and File header G-code fields
- Verified empty `machine_top_gcode` produces no extra output
- Built and tested on macOS (arm64)

Changed the help link for the 'symmetric_infill_y_axis' option from 'strength_settings_patterns#zig-zag' to 'strength_settings_infill#symmetric-infill-y-axis' to provide more accurate documentation.
# Description
When creating a new filament preset and setting the Printer Dependencies to "All", the preset does not save this setting. This issue only occurs on creation due to code that is meant to validate the data to prevent a case where the filament is compatible with none of the printers.
EDIT: While I considered redoing the data validation for this tab overall, I have now preserved the original purpose of the code, which is to add the current printer as a compatible printer only if:
- the base preset is a System preset
- the user has not specified any compatible printers
Notably, this seems to be the cause of #11959
Moving the data validation from `Preset::save_current_preset` to `Tab::save_preset` allows the Preset function to be simplified through removal of the current printer parameter.
# Screenshots/Recordings/Graphs
There is no visible change on the UI.
## Tests
Tested the following combinations of filament presets:
- System->new User
- User->new User
- User->same User
Tried to set them to All, where the System->new User should be the only case where this is replaced by a default.
In any case where there are printers already set, those settings should be kept.

Refresh filament setting overrides on preset change
The filament “Setting Overrides” page derives its UI state from multiple configs
(filament, printer, process), but this derived state was not recomputed during
preset reloads.
As a result, override widgets could reflect stale values until the page was
revisited or a user interaction triggered an update.
Recompute the filament setting overrides as part of TabFilament::reload_config(),
keeping the derived UI in sync with the active preset immediately after reload.
Fix filament preset undo/dirty tracking to match Bambu behavior
Use deep compare for filament presets so vector options report #idx keys.
Align undo/dirty mapping with indexed fields and Bambu’s filter_diff_option.
Pass explicit indices for filament override fields.
Add missing filament variant keys (retract lift bounds, ironing overrides) to filament_options_with_variant so per‑filament undo works.

* Move num_extruders config to OtherSlicingStatesConfigDef
The num_extruders configuration option was relocated from OtherPresetsConfigDef to OtherSlicingStatesConfigDef for better organization and relevance. This change ensures that the number of extruders is defined in the context of slicing states rather than presets.
* Unifi adaptative bed mesh
Renamed 'param_extruder_clearence.svg' to 'param_extruder_clearance.svg' and updated the corresponding resource reference in Tab.cpp to correct the spelling error.

Fix: Fixing the logic of the adaptive layer height for supports
Removing `tree_support_adaptive_layer_height` because its logic duplicates `independent_support_layer_height`
This new feature allows users to override flow ratios for the following extrusion path types:
* First layer (excluding Brims and Skirts)
* Outer walls
* Inner walls
* Overhang perimeters
* Sparse infill
* Internal solid infill
* Gap fill
* Support
* Support interfaces
* Change ironing angle setting to be an offset angle from the top surface angle rather offset from the layer 0 angle that changes on each layer.
* Change Ironing angle offset range from [-1,359] to [0,359].
-1 is redundant because it is the same behavior as 0 offset.
* Change ironing_angle new default value to 0.
* Update existing print profiles' hardcoded ironing_angles from -1 to 0 to reflect new default value.
* Add migration for old -1 ironing_angle settings. Remove logic for -1 ironing_angle.
* Add u8 prefix for degree symbol string
* Use solid_infill_direction instead of infill_direction for top surface infill direction. Use calculate_infill_rotation_angle to add offset to solid_infill_rotate_template if used.
* Update quality settings wiki for Ironing
* Set f->is_using_template_angle when making ironing filler objects
* Update quality_settings_ironing link from #angle to #angle-offset
