* Fix internal bridges over Hilbert Curve/Octagram Spiral sparse infill
For patterns with curved/turning anchor lines (Hilbert Curve, Octagram
Spiral), the bridge_over_infill algorithm produced incorrect results:
1. determine_bridging_angle: sampling curved anchor orientations
produced noise across all turning directions (0/90/180/270°)
instead of a single dominant one, yielding unstable bridge angles
with 180° spread. Fix: use the configured infill_direction + 90°
directly, bypassing the noisy sampling. The old blind +0.25*PI
(Hilbert) and +1/16*PI (Octagram) offsets are removed.
2. construct_anchored_polygon: curved Hilbert/Octagram anchors
intersected each vertical scan line many times at wildly different
Y positions, producing chaotic polygon sections — holes in random
places, bridges over air, rotated bridges. Fix: replace the curved
infill polylines with synthetic straight lines parallel to
infill_direction, spaced at the real infill line spacing
(flow_spacing / density). Lines are centered on the limiting_area
bbox center so that after rotation they span the full bridged_area.
Anchors are left at full bbox length (not clipped) to guarantee
every scan line finds an anchor.
Rectilinear and other straight-line patterns are unaffected.
Known limitation: some bridge edges may still terminate over air in
edge cases where the nearest synthetic anchor line is more than one
infill spacing away from the bridge boundary. This will be addressed
in a follow-up.
* fix: anchor internal bridges to actual sparse infill
Preserve real anchors across regions and align plane-path anchor origins with printed infill. Respect lower-layer rotation templates and model alignment, and sample curved bridge boundaries more finely.
Add regression coverage for anchor alignment, bridge angles and region isolation, with Orca comments explaining the geometry constraints. Verified 175 FFF tests before the comment-only follow-up; preserve CRLF in modified files.
* Fix internal bridge support contacts and separated infill origins
Restore anchor contact after bridge smoothing and share per-body pattern origins between anchors and printed infill. Recompute origins when preparation settings change.
Cover multiline counts 1, 2 and 3 and add regressions for printed bridge support, separated infill alignment and reslicing.
* Add explicit standard headers to PrintObject tests
* test: cover surface centering when infill settings change
Verify top and bottom Archimedean Chords and Octagram Spiral paths after switching centering modes or toggling separated infills. Compare reslicing against fresh slicing and document dependent infill invalidation.
* test: preserve directional surface infill when settings change
* perf: index layer islands for connected-body detection
* test: use public print pipeline for body centering checks
* build: enable /Zc:lambda for MSVC
MSVC keeps its legacy lambda processor under /std:c++17, which rejects
reading a constexpr constant inside a lambda that does not capture it
(C3493). No other compiler requires that capture, and clang reports it as
an unused one, so the two cannot both be satisfied without the flag.
/Zc:lambda selects the conforming lambda parser that clang and GCC
already use. It is implied by /std:c++20 and /permissive-, so it is only
needed while we are on C++17. clang-cl is conforming already and does not
take the flag.
It requires VS2019 16.8, so build_release_vs.bat now says 16.8+.
* build: clear 237 unused lambda capture warnings
236 captures across 81 files, 142 of them `this`. Removing an unused
capture changes no behavior; clang does not report a capture whose type
has a non-trivial destructor, so nothing held only to extend an object's
lifetime is in this set.
Nine of them are the second half of the warning, "is not required to be
captured for this use", where the capture is a const or constexpr value
the body does read. Those depend on the /Zc:lambda change in the previous
commit. One of them, in FillRectilinear.cpp, had been worked around with
an #ifndef __APPLE__ guard around the capture list, which is now gone.
GUI_ObjectTableSettings.cpp captured its reset button only to read it
inside #ifdef __WXOSX_MAC__. That branch now takes the button from the
event it is already handling.
* build: fail configure on MSVC older than 19.28 instead of dropping /Zc:lambda
cl.exe answers an unrecognized /Zc: sub-option with warning D9002 and keeps
going, so on VS2019 before 16.8 the flag is silently ignored and the build
instead dies with C3493 in FillRectilinear.cpp, nowhere near the cause.
* fix: delete three locals that are now unused
Their only remaining use was the lambda capture this branch removed. The
Clang builds set -Wno-unused-variable, so the build never flagged them.

* build: remove std::move that blocks copy elision
std::move wrapped around a temporary, or around a local being returned,
stops the compiler constructing it in place. Each edit is the fix clang
suggests, which is to delete the std::move call and keep its argument.
Three of the 39 sites save a move, the two return std::move(local) in
Print.cpp and TreeSupport.cpp:2749. The rest are equivalent either way
and match how the codebase already writes this elsewhere.
Clears 39 -Wpessimizing-move warnings.
* build: drop null checks on references and this
A reference cannot be bound to null and this cannot be null, so the
compiler folds these conditions to true and drops the guard. Seven are
if (&bitmap && bitmap.IsOk()), where IsOk() already does the work; two
test this directly. The guarded code runs either way, so removing the
dead operand changes nothing.
Clears 11 -Wundefined-bool-conversion warnings.

* Support 'Default' filament option (index 0)
Treat filament index 0 as the new "Default" (use active object/part filament) instead of using 1. Update config defaults and tooltips for wall/sparse/solid infill filament options (min/default -> 0, tooltip explains "Default"). Adjust normalization and propagation logic to respect explicit feature overrides and only apply base extruder when feature values are zero; only copy sparse->solid infill when sparse > 0. Introduce FeatureFilamentOverrideMask and clamp_feature_filament_to_valid to resolve and clamp feature filaments. Update UI lists and selection behavior to expose a "Default" entry and handle zero-based indices in PartPlate and Plater.

* Allow wipe_tower_filament to equal nozzle count
Relax the assertion in Print::extruders to permit wipe_tower_filament == config().nozzle_diameter.size(). The configuration value is 1-based and the code subtracts 1 when pushing the extruder index, so equality should be valid and selecting the last nozzle should not trigger an assertion.

* Migrate legacy feature filament defaults
Add migration logic to convert legacy feature filament selections from 1 to 0 for older 3mf files. Introduces a local migrate_legacy_feature_filament_defaults lambda in src/OrcaSlicer.cpp and src/slic3r/GUI/Plater.cpp that scans keys (wall_filament, sparse_infill_filament, solid_infill_filament, support_filament, support_interface_filament) on configs/objects/volumes, updates values, counts conversions and logs the result. Also adds a Semver check for "2.4.0-dev" in OrcaSlicer to trigger the migration for files older than that version. This preserves expected default filament selections when loading older project files.
* Update OrcaSlicer.cpp
* Extract migration helper to ConfigMigrations
Centralize legacy feature-filament default migration by moving the duplicated lambda into ConfigMigrations::migrate_legacy_feature_filament_defaults (src/libslic3r/Config.cpp) and declaring it in Config.hpp. Update OrcaSlicer.cpp and slic3r/GUI/Plater.cpp to call the new function instead of inline lambdas. The helper converts specific feature filament keys (wall_filament, sparse_infill_filament, solid_infill_filament, support_filament, support_interface_filament) from int 1 to 0 and returns the count of conversions to avoid duplicated migration logic.
* Remove DynamicFilamentList1Based and consolidate lists
Delete the specialized DynamicFilamentList1Based struct and its global instance. Update Choice registrations to use the single dynamic_filament_list for wall, sparse_infill and solid_infill filaments, and remove the extra update call for the removed instance. This consolidates filament choice handling and removes duplicated logic in Plater.cpp.

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.
