Brings belt-printer up to main 4b4a261787. Resolutions:
- G-code header (#15897, #15915): main moved the header, config and
thumbnail block later in _do_export; write_belt_header() moves with it,
still after the thumbnails and outside the BTT_TFT gate.
- _extrude: first-layer acceleration keeps the per-path first-layer plane
test with main's cached nozzle index (#16028); main's set_speed out-param
form (#16108) everywhere else.
- GCodeWriter (#16108): the arc-to-polyline fallback for machine mappings
that cannot express G2/G3 now runs in the out-param extrude_arc_to_xy,
which is the overload GCode calls, and appends to the caller's string.
- GCodeProcessorResult: the belt fields join main's forwarding assign.
- Clipper2 (#15969): belt arrange helpers take Slic3r::Point; the tree
support join types lose their ClipperLib qualifier.
- CLI arrange (#15837): belt printers still reserve no wipe tower.
- Wipe tower options (#15841): the two new sparse-layer toggles are hidden
for belt printers like the rest of the tower options.
- Keyboard shortcuts (#15706): main's registry replaces the old key switch;
the belt view toggle is re-registered in the next commit.
- Print::process: the belt purge-plan undo runs before main's SliceStarted
event.
- scripts/filament_id_snapshot.json: deleted on main (a77209af8f).
- Includes and appended tests: union of both sides.
* Add Missing Includes Across src/libslic3r
Every libslic3r source and header now directly includes the headers declaring what it uses, rather than relying on the precompiled header or transitive includes. Generated with clang-tidy misc-include-cleaner, with libslic3r headers spelled libslic3r/... so they resolve outside the library's private include paths. MultiMaterialSegmentation.hpp, Support/SupportParameters.hpp and Format/STEP.hpp are made self-contained by hand.
* Make the libslic3r Headers Compile on Their Own
Each now includes, or forward-declares, what it uses instead of relying on what its includers happened to include first. Left out: I18N.hpp, which errors on purpose when included from GUI code, and VoxelizeCSGMesh.hpp and SLA/bicubic.h, which nothing includes and which no longer compile at all.
* Add the Includes Missing From the Hand-Fixed libslic3r Headers
clang-tidy would not edit these headers while they failed to compile on their own, so the first pass skipped them. With the headers now self-contained, a second pass adds the rest.
* Keep Windows Setup Ahead of the Added libslic3r Includes
Print.cpp and Thread.cpp open with a _WIN32 block that has to come first; without the precompiled header, Print.cpp otherwise reaches windows.h through OCCT with NONLS defined and boost/regex fails. OpenVDBUtils.cpp and SLA/SupportTreeBuilder.cpp had includes inside #ifndef NOMINMAX, which libslic3r defines on Windows, so those were skipped there. .clang-tidy also ignores the MSVC STL and UCRT internals, Boost.Multiprecision's fwd.hpp and CPython's Windows include directory.
* Re-Add libslic3r Includes After the Clipper2 2.0.1 Migration
Rebasing onto main took main's version of the files the Clipper2 migration rewrote, so their added includes are restored here, along with includes for main's new code. Clipper2's individual headers are now ignored by clang-tidy: they only build the Z variant through clipper2_z.hpp, which defines USINGZ first, so including clipper.core.h and the like directly broke ClipperZUtils.cpp.
* Reject 3MF Plate IDs Below 1 Instead of Indexing Before the Plate List
The plate importer copied each plater_id from model_settings.config into the
1-based plate list after checking only the upper bound, so plater_id="0"
wrote to plate_data_list[-1] and crashed on load. Both copy sites now reject
ids below 1 with the same "invalid plate index" error already used for ids
past the end.
* Drop Malformed 3MF Paint Data Instead of Reading Past the Bitstream
Painted facets are decoded from a bitstream a nibble at a time with no bound
check, so a truncated or corrupt paint string in a 3MF (for example split
codes with no children behind them) read past the end and crashed on load and
slice. A one- or two-side split naming side 3 also indexed past the triangle's
vertices.
Every nibble read now goes through a bounds-checked reader. Loading validates
each triangle's tree and drops a malformed one with a warning, so the stored
data, used extruder states and later decoding all agree. deserialize() also
unwinds and clears any triangle whose tree is incomplete or malformed, and
has_facets() stops at a truncated triangle. Valid streams decode unchanged.
Reconciles the belt-printer branch with upstream PRs through #13723. Six
files had conflicts; three additional files needed manual follow-up fixes
where the auto-merge produced code that referenced upstream-renamed fields
or changed function signatures.
Notable reconciliations:
- TreeSupport.cpp: kept belt-floor early-exit branches around HEAD's
drop-down logic, folded upstream's `(distance_to_top > 0 ? 1 : 0)`
formula into the non-belt-floor path (upstream PR #11812). Dropped dead
`roof_enabled`/`force_tip_to_roof` locals.
- TreeSupport3D.cpp: combined upstream's safety-offset + remove_small
changes with HEAD's belt-floor clip in the per-slice trim loop. Dropped
HEAD's `else` block (superseded by upstream's rewritten bottom-contact
propagation) and re-added the belt-floor clip into the new propagation
loop. Gated the propagation on belt printers to prevent OOM when
belt-floor clipping produces empty initial slices.
- TriangleSelector.{cpp,hpp}: merged both new `select_patch` parameters
(HEAD's `up_direction` and upstream's `select_partially`); body uses
`dot(up_direction)` for the overhang angle check and forwards
`select_partially` to `select_triangle`.
- SupportMaterial.cpp: `slicing_params.soluble_interface` →
`zero_gap_interface_bottom` in HEAD's `detect_belt_floor_bottom_contacts`,
matching upstream's same-purpose rename at line 2495.
- Custom.json, GCodeWriter.cpp: simple additive merges (kept entries /
includes from both sides).
Verified by building OrcaSlicer (RelWithDebInfo) after a full deps
rebuild (Eigen v5.0.1, libigl v2.6.0 are now managed deps) and slicing
a scaled Benchy on the NORMALIZER belt-printer profile without OOM.

* Use more readable data types for storing triangle splitting information.
* fix build errors
* SPE-2063: Determine correctly which extruders are used when the object is painted by the multi-material painting gizmo.
During the serialization of TriangleSelector and also during reading serialized painting data from 3MF, we cache all used states in the painted triangle mesh.
Based on this information, we can quickly determine which extruders are used and which don't.
* Fixed an bug that filament list was not updated properly
