harrierpigeonandClaude Fable 5.1 54e079ae25 Organic supports: restore the per-slice collision, bed and belt trim
dda58b07cd stripped debug instrumentation from TreeSupport3D.cpp with a
script, and that script also deleted the loop in organic_draw_branches()
that trims every branch slice against the collision volume, the bed and,
on a belt, the belt plane.  This is the generator every printer uses, not
a belt code path, and it is the one place where raistlin7447's export
fixtures differed from main with belt printing off.  Restore the loop as
it was on main, with the belt-floor clip.

The new test prints a cube carrying a 60 mm plate with organic supports
on a flat-bed printer and checks on every support layer that no support
extrusion comes within 0.2 mm of the part's slice.  It guards that
invariant; on this fixture the loop's own effect is a sub-millimetre
reshaping of one branch (verified by slicing the fixture with and
without the loop), below the asserted gap, so the test does not by
itself fail without the loop.

harrierpigeonandClaude Fable 5.1 dda58b07cd Belt printer: supports reach the belt under a leading overhang
The slicing frame of a belt object started at its lowest vertex, but the
belt under the leading end of an overhang lies below that, by the
overhang's length times the tilt's shear.  Every support generator works
in layers at z >= 0, so none of them could reach it: normal supports
stopped at the object's own lowest layer, and the two tree generators
each carried a stack of hacks to extend themselves below it (a post-hoc
copy of the lowest base area in TreeSupport, "virtual belt raft layers"
in TreeSupport3D/TreeModelVolumes), sized from the pre-rotation bbox
and capped at global z = 0, which is only right for the trailing half
of the belt.

Start the frame at the lowest belt-floor point under the footprint
instead, less a 10 mm margin along the belt for the base of a support
column (BeltSliceStrategy::apply_preslice_transforms and
BeltTransformPipeline::compute_belt_height_and_floor agree on it).  The
layers between it and the first vertex come out empty, which belt
slicing already tolerates, and the generators need no extension at all:

- normal supports: the generator anchors its layer grid at the frame
  origin, so run it in the object frame and shift the global belt Z
  offset onto the result afterwards, as organic supports already did.
  With the offset on the object layers a top contact at negative z
  turned the intermediate-layer count negative and the generator
  allocated layers until the kernel killed it (any overhang in the
  leading half of the belt).  Drop the first-layer flange expansion on a
  belt: the first support layer is the leading tip of the support, not
  a flange, and inflating it put lines in the air ahead of the belt.
- classic tree: a node now keeps dropping until its whole circle is in
  the belt, so the branch tapers to a tip on the belt instead of
  stopping, a radius above it, when its centre crosses.
- organic: the belt is no longer a support blocker.  A blocker is a
  collision, and a branch descending onto one slides off it, down the
  tilted belt and ahead of the part; the belt is where branches end,
  which the per-layer m_belt_floor clipping already does.

The belt brim is generated after the parallel support step instead of
inside it: belt_brim_obstacles() reads every object's layers and support
layers, which another object's support step rebuilds (and, now, shifts)
at the same time.  This is the race behind the Windows arm64 segfault
in "Belt brim of each object precedes its perimeters on its own
filament".

Also: the belt tilt axis moves to Developer mode as its own row (a
shared line is shown by its first option's mode), first_layer_plane
band thickness, belt_support_floor_mode, belt_preslice_global and
gcode_back_transform are retired and presumed on, the gravity arrow is
a plain line along the up direction, and the "Show raw G-code (belt
only)" preview toggle is gone.

Regression test: "Belt supports reach the belt under a leading
overhang" slices a cube with a fin whose underside is parallel to the
layers, 20 mm ahead of the cube and up to 41 mm of slicing Z above the
belt, for normal, organic and classic tree supports, and checks that
the lowest support layer sits on the belt beneath its own lines.

HanifKoh 4895bc03b4 Remove Unused Project Includes and Forward-Declare Where a Type Is Only Referenced (#16099)
* Remove Unused Project Includes and Forward-Declare Where a Type Is Only Referenced

Generated with include-what-you-use and applied conservatively. Only OrcaSlicer's own headers, the ones under src/ and tests/, are removed or forward-declared; standard-library and third-party includes are left alone. An include is removed only when both the Release and the Debug configuration leave it unused, never from inside a conditional block, and never from a file with platform-specific blocks, which only gain includes. Files whose only use of a header sits behind a feature or debug macro (libvgcode's OpenGL ES and marker code, the ARACHNE/TESTS_EXPORT_SVGS debug output) keep their includes.

clonable_ptr.hpp gains #pragma once; it had no include guard and was only safe while Config.hpp was its sole includer.

* Remove Unused Project Includes From Files With Platform-Specific Code

A Linux include-what-you-use run cannot see the code inside _WIN32, __APPLE__ or __linux__ blocks, so its verdict is only taken where nothing the removed header declares, directly or through what it includes, is named inside those blocks. Removals also have to hold in both the Release and Debug configuration and never touch a line inside a conditional block.

* Restore the libslic3r Precompiled Header and Direct Includes Lost in the Platform Pass

The platform-file pass treated pchheader.hpp as an ordinary header and
emptied it, and left GUI_Preview.hpp and 14 other files relying on
headers they no longer reached directly.

* Restore MainFrame.hpp in ParamsDialog.cpp for the Windows-Only Reparent Call

* Include Headers That Files Reached Through Ones the Cleanup Removed

* Drop Includes Duplicated by the Cleanup or by Main's Own Additions

* Leave PreciseSeam.cpp as Main Has It After the Precise Seam Rework

harrierpigeon bbb94724ba Merge upstream/main into belt-printer
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.

HanifKoh 8a6377f087 Add Missing Includes Across src/libslic3r (#16068)
* 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.

Hanif Koh 6e33f3f5dd Share and Clamp the Build Plate Tilt Shift in Support Generators
The three support generators each computed lh * tan(tilt), which overflows
coord_t at 90 degrees and flips sign beyond it (belt sync can write up to
180). One helper now returns the tilt slope with the tilt capped at 89 degrees.

Hanif Koh 8e330f951a Merge Main into Belt Printer
Merge origin/main (00429da739) into belt-printer.

Conflicts resolved:
- src/CMakeLists.txt: keep both wxInspector workarounds.
- GCodeProcessor.cpp: keep the belt compare_pos / z_for_height lines.
- PrintObjectSlice.cpp: the belt bbox-Z guard also covers main's
  printable_region_ids bookkeeping.
- TreeSupport.cpp: the belt-floor check runs before main's PendingNode
  queueing.
- Tab.hpp: keep the belt fields, drop the removed upload description
  fields.
- tests/libslic3r/CMakeLists.txt: keep both test files.

Also included:
- eSUN PLA belt presets declare their own filament_id (OFkrxQC4) and
  scripts/filament_id_snapshot.json is regenerated, as main's filament_id
  check requires.
- Custom.json version bumped to 02.04.00.05 so the belt entries reach
  existing installs.
- Fix the ambiguous WithinRel call in the belt apron width test, which
  otherwise breaks the fff_print build.

HanifKohandraistlin7447 4deadc9dce Make Tree-Support Deterministic (#15565)
* Make tree support deterministic without giving up its parallelism

* Break equal-distance ties in the tree support MST by coordinates

* test: cover the determinism this PR fixes

The MST unit tests here cover the tie-break, but the drop_nodes rework
has no test.

Adds two cases to the tree support suite. The thread-scheduling one
slices five configs twice each and compares the support point sequence,
which is what the node ordering moves. The MST tie one pins the branch
diameter and line width that carry Prim's equal-distance ties into the
toolpaths.

slice_with_tree_support takes an optional config list so the second case
can add the tree parameters it needs, and the double-slice comparison is
shared rather than written twice.

Both fail on main without this PR. The first passes from 60d1ceb580, the
second from e148865dd6.

harrierpigeon 049612022a Perf: avoid unconditional lower-layer polygon copies in support overhang paths (R4, R5)
SupportMaterial::detect_overhangs copied lower_layer_polygons per region
even without build-plate tilt; hoist the tilted copy out of the region
loop and use the original polygons directly when untilted. TreeSupport3D
flattened lslices_extrudable to Polygons unconditionally; restore the
upstream ExPolygons offset on the untilted path.

harrierpigeon 175075fd08 Merge upstream/main into belt-printer
Brings the belt-printer work up to date with 591 upstream commits.

Conflict resolutions (12 files, 42 hunks):

- GCode.cpp: adopted upstream's per-filament/per-nozzle config refactor
  (get_filament_config_index, NOZZLE_CONFIG), the extracted
  generate_timelapse_gcode + farthest-point timelapse, and the
  ConfigOptionFloatsNullable calibration options. Re-applied the belt
  hooks on top: init_belt_writer / axis remap / FirstLayerPlane setup,
  on_set_origin, the belt-corrected calib_z for the volumetric speed
  tower, and path_on_first_layer (belt's per-path first-layer test) in
  place of upstream's layer-index on_first_layer() in the acceleration,
  jerk and overhang-detection paths. Swept upstream's new m_writer.
  uses to m_writer-> since belt holds the writer by unique_ptr.
- interpolate_value_across_layers: kept upstream's banded stepping and
  belt's object-Z-span ratio; dropped upstream's duplicate ratio decl.
- Plater.cpp: took upstream's guarded add_model(...) early-returns and
  the VFA vfa_layer_height plumbing; kept the belt temp-tower path,
  _calib_apply_belt_mode and belt_calib_flip_ringing_tower. Dropped the
  VFA "cut upper" block, superseded upstream by model scaling.
- Brim.cpp: upstream's ObjectInstanceID-keyed brimAreaMap, keeping the
  belt early-return.
- 3DScene.cpp: kept both the belt build-plate tilt up_direction and
  upstream's per-extruder printable-height shading.
- GCodeViewer.cpp: kept upstream's dim-previous-layers setup and belt's
  exemption from the same-result early return.
- TreeSupport.cpp: upstream's >= 0 roof-layer fix inside belt's
  belt-floor branch.
- calib.cpp / GCode.hpp / GCodeWriter.{cpp,hpp} / Print.hpp: upstream's
  additions adapted to belt's pointer-held writer and helpers.
- Custom.json: kept profile version 02.04.00.03 (belt) over upstream's
  02.04.00.01; both bumped from 02.04.00.00.

Building this tree needs the wxInspector dependency, which upstream
added in the interim (python3 and wxWidgets 3.3.2 were already present
in the shared deps prefix).

harrierpigeonandClaude Opus 4.7 7252f6acb7 Merge upstream/main into belt/rebase/may-18
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.

Kiss Lorand 4e507fffb2 Fix support interface semantics, gap handling, behavior; fix bottom interface generation for organic trees; fix non organic tree interfaces (#11812)
* Fix support interface semantics and gap handling

Fix zero-gap interface detection and gap initialization for supports and raft.
Ensures correct top/bottom contact semantics and avoids relying on default zero gaps.

* Additional fixes and robustness improvements

Fix incorrect coupling between top and bottom support interface spacing and density, ensuring bottom interfaces use their own parameters for smoothing and toolpath generation.
Restore correct bottom interface generation for organic (tree) supports when a non-zero bottom Z gap is used, and preserve contacts even when base polygons are empty.
Improve robustness of organic support slicing by fixing layer index drift and guarding against degenerate polygon boolean operations.

* Typo and semantics fix

differnt_support_interface_filament -> different_support_interface_filament

soluble -> zero_top_z_gap

* Fix non organic tree bottom support interface generation

Slim tree bottom interface layer numbers were capped by the object's layer number beneath it.
Fixed by refactoring the generation algorithm.

* Fix non organic tree interlaced support generation

Deterministic local interlaced support layers generation for non-organic tree support

* Enable support interface multimaterial for non organic tree

Enables mixed-material support interface behavior for non organic tree support type.

* Fix tree support interface layer counts and contact handling

- Correct non‑organic tree top interface layer budgeting so gaps don’t consume a layer (N stays N).
- Remove the extra roof interface pass that was duplicating the 2nd layer.
- Organic tree: use only the lowest contact footprint and avoid extra bottom‑contact extrusion so interface count matches the user setting.

* Bugfixes (a lot)

Many, many bugs fixed, majority edge-case but still not  playing by the rule.
Some of them:
- on multilevel base, on very small level variations the support was capped to the topmost level height
- non-organic tree had gaps for supports in a multilevel base situiation
- independent support layer height had issues with support interfaces (base support beneath bottom interface, top contact layer sometimes missing)
- organic tree had issues with small variation multi-level base
- organic tree support with zero top Z distance could overlap support-material and interface-material paths when separate materials were used
- many, many others (I lost track of them)

  the machine's physical coordinate space, gated by new
  belt_gcode_back_transform config option

- Fix support clipping z-shift calculation by removing coordinate-space
  mismatch and sync belt_floor_z_shift with global_z_offset; fix
  invalidation so posSupportMaterial no longer resets slicing params
- Add belt floor polygon clipping to non-organic tree support
  (slim/strong/hybrid) with collision surface integration in
  TreeSupportData, belt extension layers, and first-layer brim
  suppression
- Add belt floor clipping to organic tree support pipeline with virtual
  belt raft layers, per-layer polygons in TreeModelVolumes, and
  post-generation layer trimming; fix pre-existing processing_last_mesh
  bug in calculateCollision()

Fix belt floor support clipping: z-shift, invalidation, and global offset

- Fix support clipping z-shift calculation by removing coordinate-space
  mismatch (raw_bounding_box min.z vs trafo_centered m_belt_min_z) and
  sync belt_floor_z_shift with global_z_offset in global shear mode
- Fix invalidation so posSupportMaterial no longer resets slicing params,
  preventing the exact posSlice z-shift from being overwritten by the
  bounding-box approximation on support-only setting changes
- Remove double-counting of global z_offset on support layers — support
  already inherits the offset from object layers during generation

UI: gray out inactive belt sub-options, rename to mesh transforms, move to Advanced

Fix mesh clipping through build plate after belt shear/scale transform

Generalize G-code viewer designed-view toggle for full belt transform

Clip support layers to transformed belt floor plane

Supports below the tilted build plate (Z = shear_factor * from_axis - min_z)
are now clipped via half-plane intersection after generation. Belt floor
parameters stored in SlicingParameters and populated in both update_slicing_parameters()
and the static slicing_parameters() overload.

Make belt G-code viewer toggle more prominent, add B keyboard shortcut

- Add separator + teal "Belt Printer" header in legend panel
- Append [B] hint to checkbox label
- Add B key shortcut in GLCanvas3D to toggle designed/machine view
- Read belt_printer_angle from loaded G-code headers to enable belt view

Add per-axis global transform option for belt printer shear

New belt_shear_{x,y,z}_global bool configs. When enabled, shear incorporates
instance shift so objects at different bed positions get position-aware
transform (Z += factor * instance_shift_on_from_axis).

Fix global shear: use layer Z offset instead of mesh transform, add config invalidation

- Global shear offset applied as post-slicing layer print_z adjustment
  instead of mesh transform (which was absorbed by min_z normalization
  or shifted mesh out of slice range)
- Register all belt transform options in Print::invalidate_state_by_config_options
  to trigger posSlice re-slicing (the fallback only invalidated Print steps,
  not PrintObject steps — belt changes had no effect without manual re-slice)
- Belt gcode remap options added to steps_gcode (gcode-export only)
- Skip empty-first-layer check for belt objects with global Z offset

WIP: split instances for global shear, relative Z offsets, debug logging

- PrintApply: when belt global mode active, prevent instance grouping by
  adding unique Z perturbation to trafo — each copy becomes its own
  PrintObject with independent layers
- PrintObjectSlice: compute global Z offset relative to minimum Y shift
  across all PrintObjects (lowest-Y object stays at Z=0)
- Debug logging (warning level) for belt global shift values and offsets

Known issues:
- Cached posSlice results cause stale offsets when mixing copies with
  individually-added objects — need to compute min baseline outside slice()
- Supports still generate to Z=0 instead of object's global Z offset

Fix global shear for copied objects: disable shared-object layer optimization

When belt global Z shear is active, each object needs unique layer Z
values based on its bed position. The shared-object optimization was
causing copies to reuse the source object's layers (and its Z offset)
instead of computing their own position-based offset.

started work on getting supports to work properly

one step forward, one step back

this version didn't quite work.  Getting somewhere though

about to add UI controllable tests

added configuration options for supports

tweak CLAUDE.md to be more aggressive for my machine.  This commit should probably be pulled out before contributing upstream

still chasing down some bugs

moving objects between slices no longer results in improper Z-height because of caching

added more data to the debug logs

Z offset is getting more global again

still not quite there, I think there's a fundamental logic flaw?

hunting for bugs

finally have a functional fix

Add belt floor clipping to tree supports (organic and non-organic)

- Add belt floor polygon clipping to non-organic tree support
  (slim/strong/hybrid) in draw_circles() and terminate nodes at the
  belt surface instead of the horizontal build plate
- Add belt floor clipping to organic tree support pipeline with virtual
  belt raft layers for sub-floor branch generation, per-layer belt
  floor polygons in TreeModelVolumes, and post-generation layer trimming
- Fix pre-existing processing_last_mesh bug in TreeModelVolumes that
  prevented m_anti_overhang (support blockers) from ever being applied;
  skip empty first layer check for belt printers

Commits:

current approach: make a face surface to build supports to

closer!

supports now terminate on shear plane, now need to get shear plane to correct Z height

nearly there

chasing down logic issues still

committing for checkpoint, this still does not work

still got logic problems...

cull support clipping

stashing changes for now.  Going to focus on getting the global shear OFF support generation dialed first.

beginning per object shear calcs

Local shear transform is on correct Z offset now

local shear finally works now and needs more testing

global shear works now, needs thorough testing

debugging non-45 degree angles

debugging part 2

supports at all angles work now

remove debug logging

Add belt floor collision to non-organic tree support pipeline

- Integrate belt floor as a collision surface in TreeSupportData so
  branches route around the belt naturally, replacing the explicit
  termination checks in drop_nodes()
- Add belt extension layers below the object after draw_circles() to
  allow support geometry to extend to the diagonal belt surface instead
  of terminating at a horizontal first layer
- Fix coordinate overflow in belt floor polygons (scale_(1e4) exceeds
  int32), skip first-layer brim expansion for belt printers, and
  extend empty first layer check bypass to all belt modes

add debug logging, Z translate for tree supports

still not seeing any cutoff surface yet

adding debug options

attempt #2 at trees

if hit Z buildplate stop but don't set to_buildplate true

getting closer

tree support almost there, just need to get rid of the circles at the beginning

getting closer

belt / shear plane clip works, need to figure out the buidlplate plane issues

more logic, added debugging logs

supports now extend somewhat below Z=0 in global shear mode

fix bad alloc, add 10mm below build plate

fully works now

shear transform + prusa tree support generation works now.

pull out debug logging

Noisyfox 51916ff058 Avoid using auto as type of Eigen expressions. (#8577)
According to https://eigen.tuxfamily.org/dox/TopicPitfalls.html one
should just avoid using `auto` as the type of an Eigen expression.

This PR fixes most of them I could found in the project. There might be
cases that I missed, and I might update those later if I noticed.

This should prevent issues like #7741 and hopefully fix some mysterious
crashes happened inside Eigen calls.

Arthur ae6fadda4d ENH: add vertical support enforcer
Previously painting support enforces on vertical faces doesn't work, as projecting the facets downwards will give empty polygons.
Now we use a different mechanism to enable vertical paint-on enforces, by directly adding contact nodes.
Note: this feature only works with tree support as only tree support has contact nodes.

Arthur 5054ee8508 ENH: improve hybrid tree support
1. do not add interface for small overhangs so supports are easier to
   remove
2. calculate avoidance more accurately using real layer height
  jira: STUDIO-6285
3. hybrid nodes won't collide with lower layers
4. calculate max move more accurately
5. do not increase radius if next layer has collision
  jira: STUDIO-2296, STUDIO-7883
6. rewrite plan_layer_heights to prevent support layers overlap.
  Now the tree support layers are completely independent to object layers.
6. increase collision areas for interface. The top layers may be too
close to interface with adaptive layer heights and very small overhang angle

Arthur 2577b9b3a6 ENH: improve supporting sharp tails of tree support
1. sharp tails are supported by a sparse set of contact points which are
easier to remove than previously dense surrounding support.
   Organic tree support also has this feature, including all other smart
overhang detection techniques (small overhang and cantilever detection),
with the cost of slightly longer time to detect overhangs.
2. improve supporting overhang contours by adding contact points along
   contours.
  jira: STUDIO-3876
2. remove some redundant data structure.
