Say what the code does, not what it replaced

The timings and the runs that never finished belong in the commit
messages, where they can be read against the change; a reader of the
code cannot check them. Kept the cost that still explains the design.

MultiPoint also spells out the consequence: a moved-from Polygon or
Polyline is now really empty where it used to silently keep its points.

The two wall spacing comments the parallel loop reindented are plain
ASCII now, so the whole file is.

+# Polygon Clipping — High Level Design
+
+## Purpose and scope
+
+Almost every stage of slicing works on 2D regions: slices, perimeters, infill
+areas, bridges, supports and brims are all produced by boolean operations and
+offsets on polygons. libslic3r does this through two interfaces, both built on
+the Clipper2 library vendored in `deps_src/clipper2`:
+
+- `ClipperUtils` (`src/libslic3r/ClipperUtils.hpp`) takes and returns Slic3r
+  geometry: `Polygon(s)`, `ExPolygon(s)`, `Polyline(s)`, `Lines` and
+  `Surfaces`. It provides unions, intersections, differences and xor, closed
+  and open offsets, morphological opening and closing, variable width offsets
+  and polyline clipping.
+- `ClipperZUtils` (`src/libslic3r/ClipperZUtils.hpp`) clips paths whose
+  vertices carry a Z value, which callers use to tag vertices with a source
+  index or an extrusion width.
+
+No other code calls Clipper2.
+
+`ClipperUtils` declares its own `JoinType`, `EndType`, `PolyFillType` and
+`ClipType` enums and maps them to Clipper2's. Every call builds its own
+Clipper2 objects and shares no state, so slicing threads can clip
+concurrently.
+
+Clipping is one of the largest costs of slicing, and nearly all of it goes
+through `ClipperUtils`. The layer is therefore designed for throughput as much
+as for predictable geometry.
+
+## Vendored Clipper2
+
+`deps_src/clipper2` builds the static target `Clipper2`. It carries four
+changes to the upstream sources that must be carried over when Clipper2 is
+updated. The namespace switch sits at the top of every header and source, the
+other three are marked with `Orca:` comments.
+
+| Change | Files | Why |
+| --- | --- | --- |
+| Z build in its own namespace | all headers and sources, `clipper2_z.cpp`, `clipper2_z.hpp` | The library is compiled a second time with `USINGZ` in namespace `Clipper2Lib_Z`, so the 2D and the Z variants link into one binary. |
+| Engine nodes from tbbmalloc | `clipper.engine.h`, `clipper.engine.cpp` | Vertices, active edges, output points and records, local minima and `PolyTree` nodes are allocated one by one. `CLIPPER2_NODE_ALLOCATOR` routes them through `scalable_malloc`, because the default heap does not scale when all slicing threads clip at once. |
+| Concave joins at the edge crossing | `clipper.offset.cpp` | For closed paths, a concave corner is joined at the crossing of the two offset edges when that point lies within half of both adjacent edges. The upstream 3-point loop makes inward offsets of dense curves very slow to union. |
+| Rounded arc steps | `clipper.offset.cpp` | Round joins use the rounded number of steps, not the ceiling, which keeps the vertex count of round offsets that the rest of the code is tuned for. |
+
+## ClipperUtils semantics
+
+The callers of `ClipperUtils` rely on a fixed set of behaviours. Where
+Clipper2 behaves differently by default, the wrapper adjusts it.
+
+### Booleans
+
+- The fill rule is non-zero unless the function takes a `PolyFillType`. One
+  rule applies to both subject and clip; Clipper2 has no per-operand rule.
+- Collinear vertices are removed from the result. Clipper2 keeps them by
+  default, so every boolean sets `PreserveCollinear(false)`.
+- Outer contours are CCW and holes are CW. No output contour touches
+  itself: where one would pass twice through a vertex, it is split there into
+  two contours.
+- `ExPolygons` results are built from one `PolyTree64` pass. An island inside
+  a hole becomes an `ExPolygon` of its own.
+- `ApplySafetyOffset::Yes` grows the clip polygons by `ClipperSafetyOffset`
+  before an intersection or a difference, so that edges shared by subject and
+  clip do not leave slivers.
+- Open polylines are clipped with the non-zero rule and keep their direction.
+
+### Offsets
+
+- Before offsetting, input vertices closer than
+  `ClipperOffsetShortestEdgeFactor` × |delta| to the previously kept vertex
+  are dropped. This bounds the work on dense contours, and the error it
+  introduces is far below the offset distance.
+- The miter limit is at least 2. For `jtRound`, a positive `miterLimit`
+  argument is the arc tolerance, capped at |delta| / 4, and 0.25 is used
+  otherwise. Other joins use the smaller of 0.25 and |delta| / 4 for round end
+  caps.
+- A single `Polygon` keeps its orientation: a CCW polygon grows with a
+  positive delta, a CW polygon is a hole and shrinks.
+- `Polygons` follow the same rule per path. When every CW path lies strictly
+  inside the bounding box of a CCW path, which is the usual case of contours
+  with their holes, all paths are offset in one Clipper2 group. Otherwise
+  each path is offset on its own and the results are united, with the
+  non-zero rule when growing and the positive rule when shrinking.
+- `ExPolygons` and `Surfaces` are offset as one group after the contours are
+  oriented CCW and the holes CW, whatever their input orientation.
+- Zero-area paths vanish under a negative offset instead of growing.
+- Polyline offsets use the requested end type. Clipper2 already unites the
+  result, so no further union is done.
+
+### Coordinate range
+
+Clipper2 computes intersections and slopes in doubles, which hold integers
+exactly only up to 2^53 (about 9e15 units, 9,000 km). Geometry passed to
+`ClipperUtils` must stay well inside that range; near the int64 limit the
+results shift by hundreds of units. This is why the arrange `InfiniteBed` is a
+box of ±2^50 units around its centre rather than libnest2d's infinite box,
+which reaches ±2.3e18.
+
+## ClipperZUtils
+
+`ZPoint` is a `Vec3crd`, and a `ZPath` is a vector of them.
+`clip_zpaths()` runs one boolean with the non-zero rule on the Clipper2 Z
+build. The subject may be open, the clip is closed, and the result lists the
+closed paths before the open ones.
+
+The Z of each output vertex follows these rules:
+
+- An input vertex keeps its Z.
+- An intersection that lies on an end point of one of the two crossing edges
+  takes that end point's Z, preferring the subject edge.
+- Any other intersection gets its Z from the callback, which receives both
+  crossing edges, the subject edge first.
+
+Clipper2 calls the callback only when it creates an output vertex at an
+intersection, not for every crossing it processes. A callback that records
+intersections, like `ClipperZIntersectionVisitor`, therefore sees only those.
+
+The users are:
+
+| User | Z carries |
+| --- | --- |
+| `Algorithm::wave_seeds()` (region expansion) | source and boundary index; intersections get a negative index into the visitor's list of crossing pairs |
+| `Algorithm::split_line()` | index of the source vertex; an intersection gets the negated index of its source edge, so the pieces can be put back in path order |
+| `PerimeterGenerator` overhang and top-surface clipping of Arachne walls | extrusion width, interpolated along the edge at intersections |
+| Tree support anchors in `SupportCommon` | index of the source contour, -1 at intersections |
+| `extrusion_paths_append()` | extrusion width, turned into extrusion paths |
+
+## Testing
+
+`tests/libslic3r/test_clipper_utils.cpp` and `test_clipper_offset.cpp` cover
+the wrapper's booleans, orientation and offset rules. The perimeter, support
+and region expansion users are exercised by the slicing tests in
+`tests/fff_print`.

+# 3D Scene Benchmark: High Level Design
+
+## Why it exists
+
+Rendering changes, such as the realistic view, shadows or SSAO, need a number to compare
+before and after, and user reports of a slow viewport need a way to say how slow. The FPS
+overlay and the render timings overlay show live values while someone drags the camera,
+which varies from run to run with the model, the path of the mouse and the view.
+
+The benchmark renders a fixed model along a fixed camera path in both 3D views, so two
+runs on the same machine differ only by the code or the settings, and prints a report that
+can be pasted into an issue.
+
+## What it does
+
+`run_scene_benchmark()` in `src/slic3r/GUI/SceneBenchmark.cpp` is reached from Help >
+Benchmark 3D Scene, the command palette and Preferences > Graphics. After a confirmation
+it starts a new project, which asks to save the current one if needed, loads the
+OrcaSliced Combo handy model and arranges it. A small dialog in a corner of the 3D view
+then shows the progress; every other window is disabled until the run ends, so a click
+cannot change the scene being measured. Cancel or Esc stops the run.
+
+The run goes through these stages, driven by a timer while it waits and by idle events
+while it renders:
+
+1. Loading: waits until the UI job worker is idle, so the arrange job has moved the
+   objects. The orbit target is the center of the objects on the current plate, and the
+   base zoom fits their bounding box in the viewport.
+2. Prepare: renders the scene in the Prepare view.
+3. Slicing: slices the plate and switches to Preview, then waits for the G-code preview
+   to load. If slicing fails, the report holds Prepare alone.
+4. Preview: renders the scene in the Preview view, with the slicing progress notification
+   hidden.
+5. Layers: renders the Preview view again while the layer slider moves, which is what
+   makes dragging it feel slow on large prints.
+
+The dialog then shows the report, with a button to copy it. A scene cut short, because its
+view was hidden, is left out of the report.
+
+## Rendering a scene
+
+Each scene renders 30 warm-up frames, then the camera path twice, 360 frames each time.
+
+- The first pass times the frames. A frame's time is the interval between the starts of
+  consecutive benchmark frames, so it includes the event loop between them.
+- The second pass averages the render timings. The frame profiler flushes the GL command
+  queue after each section, which slows a frame down, so it only runs in this pass.
+  `FrameProfiler::start_averaging()` flags every frame begun afterwards, and
+  `finish_averaging()` waits for the flagged frames still on the GPU and returns the mean
+  CPU and GPU time of each section per profiled frame.
+- A section's GPU time is taken between a timestamp before its commands and one after
+  them. The first is only sent along with those commands, so when the GPU finishes a
+  section before the CPU has issued the next one, the wait counts in neither.
+
+The dialog renders one frame per idle event by calling `GLCanvas3D::render()`, which
+redraws the whole scene. While `GLCanvas3D::set_benchmarking()` is on, the canvas does not
+render from its own idle handler, so no other frame is drawn in between, and it skips the
+picking pass and the FPS and render timings overlays, which depend on the mouse and on
+preferences. The FPS cap does not apply, since it only paces idle redraws.
+
+VSync is turned off for the scene through `wxGLCanvas::SetSwapInterval(0)`, so the frame
+rate is what the GPU and CPU can reach rather than the display's refresh rate, and the
+previous interval is restored afterwards. When the platform cannot report the current
+interval (EGL), it is left as it is and the report says so.
+
+The camera path makes two turns around the target while the view rises three times from
+25 degrees below the plate to 85 degrees above it and the zoom goes twice between 0.6 and
+1.4 times the base zoom. The camera stays at the default distance, so the perspective is
+the same in every run. The camera the scene started with is restored at its end.
+
+The Layers scene holds the camera at the start of that path and moves the top of the layer
+slider instead, from the last layer down to the first and back up in each pass. It goes
+through `IMSlider::SetHigherValue()`, as a drag does, so every frame applies a new layer
+range to the toolpaths and the objects before drawing them, including a new shadow map when
+the shadows are static. Its warm-up frames lead into the start of the path, so the slider
+moves in every frame. The slider position it started from is restored at its end.
+
+## The report
+
+The report is plain English text, so it reads the same in every language:
+
+- The version and build commit, the GPU and OpenGL version, the viewport size and camera
+  type, and the graphics settings that change the cost of a frame: MSAA samples as read
+  from the framebuffer, FXAA, the scene cache, VSync and the realistic view options.
+- The printer and process presets the model was sliced with, marked when they have
+  unsaved changes, and the toolpath vertices and layers they produced, since the Preview
+  scenes cost more with more toolpaths.
+- For each scene, the average FPS and the average, median, 95th percentile, 99th
+  percentile and maximum frame time. Percentiles are nearest-rank, so each is a measured
+  frame (`frame_time_stats()`).
+- For each scene, the render timings table: the CPU and GPU milliseconds of each section
+  of a frame, and their total. Without timer queries (OpenGL 3.3 or `ARB_timer_query`) the
+  table says that the driver does not support them.

+# Section view — High Level Design
+
+## Purpose and scope
+
+Section view hides whatever lies between the camera and a plane, so the user can look inside
+objects in Prepare and in the assembly view, and inside the toolpaths in Preview. It is a view
+setting: it changes nothing in the model, the slice or the project file, and it does not reach
+plate thumbnails.
+
+The user controls it from the section button of the canvas toolbar in the bottom left corner of
+the 3D view. The button opens a panel above it with a slider for the depth of the cut, a "Set
+viewing angle" button that turns the plane to face the camera at the same depth, and a button that
+resets the depth to zero. The panel is an ordinary overlay window, not a popup, so the scene keeps
+taking clicks and drags while it is open; the button or Esc closes it again. Esc closes the panel
+before it closes a gizmo or clears the selection. The button is highlighted
+while a section cuts the scene and has shortcuts of its own: the mouse wheel over it moves the
+plane, a right click switches the section off and back on, and a middle click sets the viewing
+angle. Alt + mouse wheel moves the plane anywhere in the 3D view, with or without a gizmo open.
+
+## State
+
+Prepare and Preview share one section view, so a cut made in either tab is the same cut in the
+other. The assembly view, whose objects sit apart from their places on the plate, and the Design
+tab keep their own. The section itself is two values.
+
+- **Ratio**, from 0 to 1. At 0 the section is off. As the ratio grows, the plane sweeps the
+  sphere around the objects, from its side facing the camera to the opposite side, so at 1
+  everything is cut away.
+- **Normal**, taken from the camera direction the first time the section is switched on, and
+  again whenever the user sets the viewing angle. The plane keeps that orientation while the
+  camera orbits and while the section is off, so the cut face can be seen from any side and
+  bringing the depth back to 0 does not lose the angle.
+
+The ratio in use when the section is switched off is kept, and the right click on the button
+brings the section back at that ratio, which restores the same cut. Whether the panel is open is
+shared along with the section.
+
+The sphere is recomputed every frame from the volumes of the canvas the section view belongs to:
+the objects on the current plate, or every object when that plate is empty. Preview holds no
+objects of its own, so it places the plane across the volumes of Prepare, which makes it cut the
+toolpaths exactly where Prepare cuts the objects. Only G-code opened on its own, without objects,
+is measured by its toolpaths. In the assembly view the sphere is around the whole assembly. The
+ratio therefore keeps its meaning when objects move or the user switches plates. It is not a
+fixed position in world space.
+
+Only the tab on screen can change the section, and switching tabs redraws the whole scene and
+closes the open gizmo, so neither tab ever shows a stale cut.
+
+## Where the plane applies
+
+`GLCanvas3D::_get_section_view_plane()` turns the state into a plane in the convention of
+`ClippingPlane::is_point_clipped()`. Everything that draws or picks the scene reads that plane.
+
+- **Volumes.** The plane goes to the `clipping_plane` uniform of the volume shaders. The same
+  uniform serves the gouraud, phong and X-ray passes and the colour picking pass.
+- **Cut faces.** Clipping only discards fragments, which would leave the cut volumes hollow.
+  `_render_section_view_caps()` draws their cut faces with one `MeshClipper` per model part the
+  plane passes through. A clipper recomputes its face only when the plane or the volume moves.
+  Modifiers, the wipe tower and SLA auxiliaries get no face.
+- **Toolpaths.** libvgcode takes the plane through `Viewer::set_clipping_plane()`. It draws each
+  extrusion as only the faces of a diamond-section prism that turn towards the camera, so
+  discarding the fragments on the clipped side would leave open shells. Instead, the segment
+  shader follows the view ray from a fragment that is cut away to the plane. When the
+  extrusion's diamond section still holds that point, the fragment is shaded as the cut face, lit
+  as the plane faces; otherwise it is discarded. The cut face keeps the depth of the fragment it
+  replaces, which is safe: along that ray everything else still shown lies behind the plane. The
+  shader writes no `gl_FragDepth`, so early depth testing survives. Option markers are cut away
+  whole, by their centres. The shadow casters draw with a program of their own, which takes the
+  plane and discards the fragments on the clipped side, so what is cut away casts no shadow either.
+  Their cut faces are not drawn, since the part left behind casts the shadow of its own section.
+  Preview shells are drawn by another shader and are not clipped.
+- **Picking.** `get_raycaster_clipping_plane()` returns the same plane, so hover, selection and
+  the perspective pan anchor ignore what the user cannot see.
+
+## Gizmos
+
+A gizmo that clips its object itself owns the gizmo data pool's `ObjectClipper`, and its plane
+replaces the canvas section while the gizmo is open. `GLGizmosManager::get_clipping_plane()`
+reports that plane, or nothing when no open gizmo has a clipper. There are two cases.
+
+- **Painting tools and brim ears** show the canvas section on the object they edit.
+  `GLGizmosManager::update_section_view()` copies the ratio and normal into their clipper
+  whenever the pool is updated or the section changes. The clipper then places the plane across
+  the edited instance, which is the only object shown. The painting tools keep clipping their
+  own triangles, raycasts and cut face through it. Brim ears always cut horizontally from the
+  top, because the ears sit on the plate. At ratio 0 the clipper holds no plane at all, so the
+  raycasts are not clipped.
+- **Cut and mesh boolean** use the clipper for their own purposes, so the canvas section is
+  suspended while they are open.
+
+Every other gizmo, including move, rotate and scale, leaves the canvas section in place.
+
+## Alt + mouse wheel
+
+The canvas handles Alt + wheel after the gizmos had their turn, so it works the same in every
+tab and with any gizmo open. On Windows, releasing Alt when no key was pressed since it went down
+opens the window menu, and a wheel turn does not count as a key. Under the custom title bar that
+menu is invisible, yet it takes the keyboard and the next click, which looks like a frozen 3D
+view. After Alt + wheel the canvas therefore consumes the Alt release instead of passing it on.
+
+## Redraw
+
+The button and the panel are part of the ImGui overlay, which is built after the frame's scene is
+drawn. A change to the section therefore marks the scene dirty and asks for one more frame. The
+cached scene is never reused across a change.
