Unify the below-plate view across the painting gizmos

The painting gizmos clip the selected instance at the plate, so a sinking object stopped at the bed with nothing to show how it continues below it, and the plate disappeared along with the bed mesh. Give every paint tool the same view of that region: - Draw the part of the selected instance below the plate at 50% opacity with depth writes off, so it reads as the object going through the plate. - Keep the plate and its grid while the bed mesh is hidden, instead of losing every reference plane in the scene. - Mark the plate intersection with a 0.4 mm outline rather than an opaque filled cap, which covered the model and hid the ghost from above. - Gate the bed mesh and the below-plate pass on the same predicate. Texture displacement derives from GLGizmoPainterBase like the other painters but was missing from the gizmo type list in is_bed_visible(), so it kept its bed. - Add GLVolume::simple_render()'s ban_color_volume so the ghost keeps its alpha for volumes with MMU segmentation facets, whose sub-models carry their own opaque filament colours, and stop gating the ghost on is_active: the colour painter marks the whole instance inactive and draws it in its own pass.

 Runtime backend detection elsewhere uses Orca's `is_running_on_wayland()` / `is_running_on_x11()`

+- **Rule:** On NVIDIA and hypervisor guests reach for `WEBKIT_DMABUF_RENDERER_FORCE_SHM` before
+  `WEBKIT_DISABLE_COMPOSITING_MODE`. **Why:** the proprietary driver and virtual GPUs cannot back WebKit's
+  hardware DMABUF renderer, leaving web views blank or slow; FORCE_SHM keeps accelerated compositing and only
+  skips the hardware path, while disabling compositing drops it. Threaded scrolling is a separate,
+  release-dependent default (off in 2.44/2.45, on from 2.46). `WEBKIT_DISABLE_DMABUF_RENDERER` is not a
+  substitute — it is read first, leaves the transport set empty (no compositing from 2.44 on, where the
+  X11/Wayland fallback renderers were removed) and has a reported crash path. On Debian/Ubuntu and
+  openSUSE the `isNVIDIA()` patch returns before the FORCE_SHM check, so `WEBKIT_FORCE_DMABUF_RENDERER=1`
+  must clear it first; that variable exists only in those patches. WebKit reads all of these once per
+  process, before the first WebView.
+  The test is `/proc/driver/nvidia/version`, so a hybrid laptop that renders on its iGPU also takes the
+  shared-memory path, which is a per-frame GPU readback rather than zero-copy; exporting
+  `WEBKIT_DMABUF_RENDERER_FORCE_SHM=0` in the environment restores the hardware path.
+  ```cpp
+  // Wrong: kills compositing and threaded scrolling (and can crash on modern WebKit)
+  ::setenv("WEBKIT_DISABLE_DMABUF_RENDERER", "1", false);

 - Use the [Localization glossary](https://github.com/OrcaSlicer/OrcaSlicer_WIKI/blob/main/developer_reference/localization_glossary.md) as the source of truth for recurring terms, so the same English term is always rendered the same way within a language, and terms that must stay in English (brand/product names, acronyms, materials, file formats, G-code tokens, macros/variables/identifiers) are not translated.
- If a term's established translation changes, update both the affected `.po` files and the glossary (`localization_glossary.tsv`, then regenerate) so they stay in sync.
+- If a term's established translation changes, update both the affected `.po` files and the glossary (`developer_reference/glossary/<lang>.tsv` in the wiki, then regenerate) so they stay in sync.
 - Translate the *meaning*, not the words. Check what the string actually controls before translating it — English reuses one word for different things. `Flow ratio` (multiplier), `Flow Rate` (throughput) and `Flow Dynamics` (pressure compensation) are three different terms; `extruder` may mean the toolhead, the feeder motor, or the nozzle depending on the string.
 - Reuse one template per recurring message shape (`Failed to connect to …`, `Are you sure you want to …?`), even where the English wording varies.

+# Color picker
+
+The color picker is a local HTML dialog hosted by `ColorPickerDialog`, a
+`WebViewHostDialog` subclass. Its header and implementation own the ordered
+selection contract and shared filament conversion. Bridge validation, favorites
+persistence, placement and gettext strings remain private to the implementation.
+Its colors use the existing `ColorRGBA` utility.
+It uses a native title bar and fixed window border, allowing dragging but no
+manual resizing or maximization. Native title-bar colors use the application's
+shared dialog dark-theme update on creation and theme changes.
+Like SpeedDial, the host disables browser zoom accelerators, restores native
+WebView focus on activation and readiness, and synchronizes layout and the macOS
+viewport before repainting the backend. Activation never dismisses this modal
+dialog; focus restoration preserves an active editor and its partial input.
+The initialized page reports
+its intrinsic content height; native code validates the current page identifier
+and bounded numeric height, converts CSS pixels to device-independent window
+size, and fits within the display's work area. Identical sizes are ignored. The
+page observes content rather than viewport height, so resizing does not create
+a feedback loop; oversized content remains scrollable.
+The panel snapshots the triggering color or More Colors button's screen rectangle.
+It aligns below the button, flips above when needed, and clamps to that button's
+display work area on initial display. Later content and DPI changes update only
+the client size, preserving the position chosen by dragging the title bar.
+wxGTK clears the dialog's default
+parent-centering constraint and reapplies its native position after showing,
+bypassing wxGTK's requested-position cache. Absolute top-level placement remains
+subject to the window manager; Wayland compositors control it. The official filament palette's
+existing placement is independent of this custom panel.
+A solid selection contains one color; a gradient contains exactly two ordered
+endpoints. The bridge represents these as `{"type":"solid|gradient",
+"colors":["#RRGGBBAA", ...]}`. RGB input is also accepted and becomes opaque.
+Native validation rejects malformed hex and incorrect cardinality.
+
+The project filament color action and the official filament picker's More Colors
+action enable two-endpoint gradients and independent endpoint alpha. The preset
+combo box reads project colors in their stored vector order locally and applies
+changes through `sync_colour_config`,
+retaining the existing RGB/RGBA profile/project formats and dirty marking.
+Sidebar gradient and segmented multicolor swatches draw colors in the supplied
+order without sorting them.
+Opaque colors use `#RRGGBB`; nonopaque colors use `#RRGGBBAA`, including fully
+transparent alpha `00`. Initial selections, alpha-only edits and cancellation
+retain stored alpha. Ordered
+custom results bypass the official palette's `FilamentColor` set. Choosing an
+official swatch retains its existing palette behavior.
+The Linux sidebar's Change extruder color menu uses this same custom editor and
+the filament swatch anchor, including alpha, ordered gradients and configuration syncing.
+
+Striped colors and gradients with more than two endpoints cannot be represented
+by this editor. A notice explains that the current selection is retained; the
+editor starts from the first color, and unchanged confirmation is a no-op.
+Cancellation is also a no-op. If the WebView backend cannot initialize, a local
+unavailable panel offers Cancel and Escape, without opening a system color picker.
+
+Generic color option fields use an ordinary color button on every platform and
+open the same panel with gradients and alpha disabled. The panel is anchored to
+the field button. Empty or invalid field values remain undefined (the empty
+string), distinct from opaque black. Right-click resets to undefined. Cancel does
+not notify the field; confirmation and reset notify only when its RGB string
+changes. Programmatic assignments remain silent, and reading a field never
+writes legacy favorites.
+
+AMS material settings retain their fixed/AMS swatches and first-level popup. Only
+its custom-color action opens the solid, opaque editor, anchored to that custom
+control. The transient popup releases its grab while the modal is open and returns
+to the same selection on cancellation. Confirmation uses the existing default-color
+and packed RGBA event path. Device permission/status checks remain at the first-level
+entry.
+
+Texture import's color-mapping Add Material action opens a solid, opaque editor
+anchored to the mapping row. The existing filament limit is checked before opening.
+The first-level material popup closes as an action; its callback is copied before
+dismissal, so popup destruction does not invalidate the modal's completion path.
+Confirmation invokes the existing virtual-filament callback once; cancellation
+adds no material.
+
+Native gettext strings are installed at document start. Static page labels and
+palette names use stable English keys; RAL codes, channel symbols, and numeric
+labels remain data. The palette color values do not depend on the UI language.
+The application locale also sets the document language. Numeric editor validation
+uses the application's gettext messages, rather than browser language defaults;
+missing translations fall back to the stable English keys.
+
+The pure color/state regressions run with
+`node --test resources/web/dialog/ColorPickerDialog/colorpicker.test.js`.
+Optional real-browser regressions live beside them in
+`colorpicker.browser.test.js`. They use an existing Playwright installation
+(`ORCA_PLAYWRIGHT_MODULE` can name its module path) and an installed browser
+(`ORCA_BROWSER_EXECUTABLE` can name its executable), without adding a production
+dependency. They cover bridge initialization, capability combinations, invalid
+editor recovery, ordered endpoint alpha, favorites, gettext keys, and live theme
+changes. These browser checks complement native contract/persistence tests; they
+do not establish the full native modal confirmation and favorites journey.
+
+Gradient and alpha capabilities are independent and default off. Unsupported
+gradients are rejected; disabled alpha normalizes the selected result to opaque.
+Favorites retain both capabilities independently of the current caller. The page
+stores alpha as a byte and only converts to percentage when displaying or editing
+opacity, so switching endpoints does not change alpha precision.
+
+The page starts disabled. Each document supplies a page identifier in its ready
+message, receives native initialization, and acknowledges it before native code
+accepts confirmation or favorite updates. Repeated initialization does not reset
+edits, and messages from an obsolete document are ignored. Native WebView message
+handling is deferred and guarded by a lifetime token. Only a validated confirmation
+sets the optional result. Cancel, Escape and native window close leave it empty.
+
+Favorites belong to application configuration, separately from the selected result,
+in the editor configuration returned by `AppConfig::config_path()` under `data_dir()`.
+The `color_picker` section has string `version` equal to `1` and a `favorites`
+string containing a JSON array of typed selections. Native helpers normalize and
+deduplicate this array in order and limit it to 24 entries. Updates replace the
+entire section and immediately call `AppConfig::save()`, so accepted favorite
+changes survive cancellation. Empty arrays are saved explicitly. Core `AppConfig`
+only stores the raw section; color validation belongs to the GUI boundary.
+
+When the section is absent, valid solid colors from `custom_color_list` are imported
+once, without changing that legacy section. The legacy native picker saves decimal
+`r,g,b,a` byte strings; hexadecimal RGB and RGBA strings are also supported. Migration
+strictly validates all four decimal channels and preserves alpha. Gradient strings
+and malformed values are ignored. The new version and an empty array are
+saved even when there is nothing to import. A present section with an unknown or
+missing version is left untouched and disables favorite writes. Malformed version
+1 data is displayed as empty and remains on disk until the user explicitly saves
+a valid replacement. Other configuration sections and project/profile color
+formats are independent of this storage.
+
+Interface colors consume the host's `data-orca-theme` and `--orca-*` contract through
+shared styles. The picker opts into scoped global control roles. Application theme
+changes update UI surfaces without reloading the page or changing color data.

+# Focus mode (hiding inactive plates) — High Level Design
+
+## Purpose and scope
+
+"Focus mode" is an entry of the canvas menu in the bottom left corner of Prepare. Turned on (eye
+lit), the 3D view hides the inactive plates and shows the current plate alone, so a project with
+many plates can be worked on one plate at a time. Turned off, every plate is shown. 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 choice is kept in the app config as `focus_mode`, off by default.
+
+Preview needs no such option, as it already draws the current plate alone and has its own plate
+toolbar. The assembly view and the Design tab do not lay objects out on plates, so the entry is
+disabled there.
+
+## What is shown
+
+The current plate is drawn with its bed, label and icons; the other plates are not drawn at all. The
+world axes, which Prepare draws at the corner of the first plate, move to the corner of the current
+plate, where Preview draws them.
+
+An object instance is shown when its footprint, the XY bounding box of the convex hulls of its
+volumes, overlaps the current plate, or when it is selected. The test is made per instance, so the
+parts of an object are shown or hidden together, and a wipe tower follows its plate the same way.
+It is geometric rather than the plate membership `PartPlateList` keeps, because an instance stays on
+the plate it was first placed on: an object of another plate that reaches over this one, or one too
+large for any plate, would otherwise be invisible while it takes room on the current plate. A
+selected instance stays visible so that what a selection or a gizmo acts on is never hidden, for
+instance an object picked in the object list on another plate.
+
+## Hiding
+
+A hidden object is neither drawn nor picked. `GLCanvas3D::_update_inactive_plates_visibility()`
+runs at the start of each frame of Prepare. It clears `GLVolume::is_active` on the volumes of the
+hidden instances and deactivates their raycasters, which every render pass, the hover and rectangle
+selection, the shadow and center of mass markers already respect. It also deactivates the raycasters
+of the other plates, whose icons would otherwise still take clicks where nothing is drawn. The state
+persists between frames, so the raycasts made while handling the mouse, such as the anchor of a pan,
+see the same scene as the frame.
+
+Other features clear `is_active` too: gizmos hide the objects they do not edit and show them all
+again when they close. `GLVolume::on_hidden_plate` records which volumes this update hid, so it only
+shows again what it hid itself, and it waits for a gizmo that hides objects to close before doing
+so. A volume another feature made active again is hidden again on the next frame. While Focus mode
+is off and nothing is left hidden, the update returns at once.
+
+## Switching plates
+
+The other plates cannot be clicked while Focus mode hides them, so a compact counterpart of the Preview
+plate toolbar takes their place: a column of plate thumbnails in the top left corner, below the top
+toolbar, shown when the project has more than one plate and no gizmo is open. The thumbnails are the
+ones the Preview toolbar shows (`PartPlate::thumbnail_data`); the canvas rebuilds its textures when
+`Plater::plate_toolbar_image_version()` changes, a counter each consumer tracks on its own so that the
+Preview toolbar's dirty flag is left alone. That counter moves after almost every edit, so the
+thumbnail of the current plate, the only one edited while the others are hidden, is drawn again each
+time, and the other plates' only once an edit to them has invalidated theirs. The current plate has an
+accent border, a hovered one the gray border of the Preview toolbar, empty plates are dimmed and the
+plate number sits in the corner; the tooltip gives the plate name. A click selects the plate and
+clears the selection, as a click on a plate row of the object list does. The column scrolls when it
+does not fit above the 3D navigator or the canvas toolbar. Its scrollbar works as the Preview
+toolbar's, with which it shares its style: it shows only while the mouse is over the column or drags
+the bar, and the mouse wheel scrolls the column either way.
+
+Whatever selects a plate while the others are hidden, the camera moves its target over the new plate
+and keeps its angle, distance and height (`PartPlateList::select_plate()`), so the plate comes into
+view where the previous one was. A zoom to all plates, as after loading a project or adding a plate,
+frames the current plate instead. Turning Focus mode on does the same, so the current plate fills the view.

+# Tooltip illustrations
+
+The texture-displacement panel's tooltips can carry a picture under their text: a still image, or a
+short animation that loops while the tooltip is open. Several settings in that panel describe a shape
+rather than a number - what Rotation turns, what Tile repeats, what Invert turns inside out - and a
+sentence about a shape is read twice and understood once.
+
+## Where a tooltip is drawn
+
+`GLGizmoTextureDisplacement::panel_tooltip()` replaces `ImGuiWrapper::tooltip()` throughout the panel.
+It differs in two ways.
+
+It places the tooltip beside the panel instead of under the mouse. The panel is pinned to the right
+edge of the canvas, so a tooltip following the mouse covers the control it is explaining, and one
+carrying a picture covers most of the panel with it. The tooltip goes to the left of
+`m_tooltip_anchor_min`/`_max` - the panel's own screen rectangle, or the texture picker's while that
+popup is up and the tooltip comes from inside it - and to the right only when there is no room on the
+left. This is the placement the picker popup itself already uses.
+
+ImGui normally keeps a tooltip glued to the mouse and ignores `SetNextWindowPos()`. Orca's imgui
+branch honours a position set for a tooltip (see the `ImGuiWindowFlags_Tooltip` branch of `Begin()` in
+`deps_src/imgui/imgui.cpp`) and still clamps the result inside the canvas, which is what keeps a tall
+tooltip near the bottom edge on screen.
+
+It also gives the tooltip a fixed width rather than one derived from its text, because a picture has
+to be laid out against something, and a column of tooltips that are all one width is steadier to read.
+
+## Where the pictures live
+
+`resources/images/texture_displacement/`, as PNG, JPG, BMP or GIF. A tooltip names them by file:
+
+```cpp
+hover_tip(_u8L("Repeats the texture across the painted area. ..."),
+          { { "tile_off.png", _L("Off") }, { "tile_on.png", _L("On") } });
+```
+
+Several in one tooltip are laid out side by side at equal widths, which is how a setting is shown as a
+comparison - the same model at two values of it. The caption under each is translated; the file name
+is not.
+
+A file that is missing or will not decode is skipped, and a tooltip whose pictures are all missing is
+exactly the text tooltip it was before. So the art for a tooltip can land after the tooltip does, and
+a half-finished set never breaks the panel.
+
+## When a tooltip appears
+
+A tooltip waits for the pointer to rest on its control for 0.45 s. The panel is dense and the tooltip
+lands on the model beside it, so with no wait a sweep from the top of the panel down to Bake flashes a
+dozen large panels over the scene. Once one has just been up, the wait drops to 0.1 s for 0.7 s
+afterwards, so reading several settings in a row stays quick - but not to zero, or that same sweep
+would flash again the moment one tooltip had been seen.
+
+No tooltip appears at all while a control is being used - a slider dragged, a value typed into one, a
+combo open, a layer card being dragged. The pointer sits on the very thing being edited, so a tooltip
+there covers the model exactly while the user is watching it change. The full wait comes back
+afterwards rather than the short one: having just let go of a slider is not a reason to be shown a
+picture of it.
+
+A pointer resting on a control produces no events, and the canvas only renders when something asks it
+to, so the wait has to ask for its own frames, and so does an animation once one is on screen. So does
+a tooltip that has just appeared, animated or not: ImGui hides a window on the first frame it is
+submitted while it measures it, and does so every time a tooltip reappears because those windows are
+recycled, so the frame a tooltip is decided on is never the frame it is seen on. Both use
+`GLCanvas3D::request_extra_frame()`, which ends `on_idle()` with `evt.RequestMore()` and so obliges wx
+to deliver the next idle. `schedule_extra_frame()` is not enough on its own: it only arranges a timer
+whose event an idle event is assumed to follow, and on_idle renders nothing unless the canvas was
+already dirty when it ran. Asking for frames as fast as they come is safe here because which frame is
+drawn comes from the clock, not from the frame count, so a redraw that arrives early simply draws the
+same frame again.
+
+## Decoding and playback
+
+`slic3r/GUI/AnimatedTexture.hpp` decodes a file once and uploads one GL texture per frame. Stills go
+through `wxImage`; GIFs go through `wxGIFDecoder`, whose raw palette indices are composited here frame
+by frame, replaying the disposal method each frame asks for. That replay is what makes an animation
+look continuous: a GIF frame is a sub-rectangle drawn over what came before it, so an animation that
+only re-sends the pixels that changed draws as a flicker of disconnected patches without it.
+
+A frame delay of 0 or 1 hundredths of a second is read as 100 ms, the convention browsers settle on,
+so an animation authored against that plays at the speed it was authored at.
+
+The animation restarts when its tooltip opens, rather than running off a free-running clock: these are
+short loops of one setting going from one value to another, and joining one halfway through shows the
+end of a change the user never saw the start of.
+
+Which frame is drawn is measured on a real clock, not `ImGui::GetTime()`. Nothing in OrcaSlicer ever sets
+`io.DeltaTime`, so it keeps imgui's default of 1/60 per frame and imgui's clock counts frames rather
+than seconds. On a canvas that renders only when asked, that is not a clock at all: an animation driven
+by it crawls while the canvas is idle and races while a moving mouse is rendering it flat out.
+
+## Making one
+
+`scripts/gen_texture_displacement_tips.py` draws the lot, in four languages, picked by what the
+setting actually is:
+
+- **A shaded relief**, for the settings that are about a pattern: Depth, Tile, Tile size, Rotation,
+  Repeat/Mirror, Smoothing, Edge fade, Invert, Blend and the Normal, Fast, Checker and Distortion
+  views. One motif - a ring inside a square frame - runs through all of them, because using one shape
+  everywhere is what lets two pictures be compared: whatever differs between them is the setting,
+  since nothing else is.
+- **A flat mesh of triangles**, for the settings that are about the mesh or about a tool: the paint
+  tools, brush size, the connected-area fill, subdivision, feature-adaptive refinement, remeshing,
+  hard edges, slivers and the wireframe view. These carry the one accent colour in the set, meaning
+  "painted", because that is the only thing in such a picture that is not geometry.
+- **A section**, for Midlevel and for smoothing the geometry. The reason generalises: shading reads
+  slopes, so a height field moved up or down as a whole shades identically to where it started, and
+  any setting whose meaning is *where the surface sits relative to where it was* is invisible from
+  above and has to be drawn from the side.
+- **A flat ramp of greys**, for Mix filaments, Mixed colors and Denoise. Those are about which
+  filament a spot ends up as; lighting one would only add a second thing changing between two
+  pictures meant to differ in one.
+
+The five Mapping pictures are one ball with a checker laid on it five ways, which is the whole of what
+choosing a projection does - except Unwrap, which is not a projection onto the model at all and so is
+drawn as the flat layout it produces.
+
+Captures of the real tool are still the first choice for anything involving a real model or real
+filament colour: Bake, the mixed-colour count on a photograph, Adjust placement, the frame window and
+the UV editor's seam tool have no picture yet for that reason.
+
+Either way:
+
+- Square, around 256 px (192 for an animation, where every frame ships). The tooltip is about 20 em
+  wide, so that is roughly native size on a 100% display and downscales cleanly above it. A single
+  picture is capped at 10 em tall and centred, two side by side take half the width each.
+- Neutral grey. These say what a shape does; colour in one reads as a third thing the setting does,
+  and has to work against both themes.
+- Animations loop seamlessly and stay short - 16 frames at 100 ms, under about 150 KB. They sit in
+  `resources/`, which ships with every copy of the application. A sweep driven by a cosine over the
+  frame count loops with no step, since it starts and ends at the same value and the same rate.
+- No text in the picture. Captions are translated; pixels are not.

+# Travel optimization — High Level Design
+
+## Purpose and scope
+
+Inside an island, the infill paths of each region are chained into one print
+order by a greedy pass that joins the closest free path ends first. That pass
+leaves its longest joins for last, and they often cross the whole island. Two
+things shorten the travel between infill paths:
+
+- the fill generators join their lines into as few paths as they can, since
+  every separate path needs a travel to it;
+- the G-code export refines the greedy chain with a local search that shortens
+  the straight-line travel between the paths.
+
+The refinement covers every chain that `chain_and_reorder_extrusion_entities()`
+builds from a start point: the infill and ironing of `GCode::extrude_infill()`
+and the support of `GCode::extrude_support()`, as well as the order of objects
+and islands under `print_order` Default. It changes only the order and the
+direction of the paths, not the paths or the walls. Neither part has a setting.
+
+## The chain
+
+`ObjectByExtruder::Island::Region::append()` flattens every sortable fill
+collection into its paths, so the paths of all the fills of a region in one
+island are chained together. A collection that must keep its order (`no_sort`:
+monotonic, concentric, a forced fill order, the flow calibration) stays a single
+entry that cannot be reversed. Paths that must keep their direction cannot be
+reversed either: Grid's, since it alternates their direction between layers for
+strength, and those of a fill with a forced order. A loop starts and ends at the
+same point, so reversing it changes nothing.
+
+`extrude_infill()` chains each region from the current nozzle position with
+`chain_and_reorder_extrusion_entities()`, and chains the paths inside a nested
+sortable collection the same way; `extrude_support()` chains the support paths
+of a layer so too, unless they keep their order. The overload without a start
+point, used to chain collections while slicing, keeps the greedy chain. The
+order the fill generators give their paths does not reach the G-code for a
+sortable fill, which is chained again.
+
+## Connecting the lines
+
+Most patterns cut their lines at the infill boundary, and `Fill::connect_infill()`
+joins pairs of line ends that are neighbors on a boundary contour by the arc of
+wall between them, shortest arcs first, as long as neither end is joined yet and
+the join closes no loop. An arc is joined when it is shorter than
+`infill_anchor_max`, or than two anchors and a line width if that is longer:
+two ends further apart each get an anchor toward the other, and where those
+would meet, the join prints about as much wall as one path instead of two.
+
+Regular patterns leave many arcs of the same length, and the order among them
+decides the pairing. In an arbitrary order the pairs along one wall can fall out
+of step, such as lines 1–2 and 3–4, then 6–7 and 8–9, which leaves the end of
+line 5 loose, and every loose end starts or ends a separate path. So the arcs
+are also sorted in steps of half the line spacing and, within a step, along each
+contour forwards and backwards, which pairs the ends of a wall in one phase.
+Each order is replayed on the flags and a union-find of the lines, without
+building any path, and the one that joins the most lines is used; a tie keeps
+the shortest-first order.
+
+The replay includes the last pass, which joins any two open ends that are
+neighbors on a contour. With multiline infill the main pass leaves the copies of
+one line to that pass, so that each copy reaches a wall of its own. Two
+neighboring groups cut at both walls can then be joined at either wall by arcs
+of the same length: at one, their open ends stay next to their own copies, which
+the last pass joins, so each line prints out and back; at the other, the copies
+end up in separate paths printed apart.
+
+A line end left unpaired gets an anchor, a piece of the wall at most
+`infill_anchor` long. It runs toward the nearest open end of another path,
+looking up to 64 ends along the contour, since the next path usually starts
+there; without one it takes the side with more free wall. With multiline infill
+an anchor toward a copy of the same line stops short of the copy rather than
+printing over it. A copy is a neighboring end less than the group width
+(`multiline` spacings) across the line, at any wall angle, while the next group
+lies a whole line spacing away. Meeting the wall at an angle θ, the copy covers
+half a width over sin θ of the wall on each side of its end, so the anchor stops
+that far and half its own width before it, or is left out; the end still counts
+as anchored, so the last pass pairs the other ends as before.
+
+Last, `Fill::fill_surface_extrusion()` joins the sparse infill lines whose ends
+are at most two line spacings apart with a straight piece. With the anchors off
+(`infill_anchor_max` 0) nothing above runs and this is the only joining; with
+them on, it takes what the steps above leave next to each other, such as two
+anchors that stop just short of each other or a short piece cut off by a corner.
+A gap that short leaves no room to print anything in between, and as a travel it
+is the one hop a reordering can trade for a longer travel that retracts.
+Multiline copies leave the most such ends: one spacing apart across the line,
+their ends where it meets a wall at an angle θ are one spacing over sin θ apart
+along it, so two spacings reach walls met at 30° and steeper.
+
+Ends that meet are joined first, then the gaps between the leading ends of their
+lines, along each line's overall direction, then the rest, shortest first within
+each, without closing a loop or crossing a line or another join. Taking the
+leading ends first joins every pair of copies at the same side, which leaves
+their open ends next to each other; by length alone, neighboring pairs were
+joined at different walls and the travel between them crossed the island. Lines
+that cannot reverse, such as Grid's, only join the end of one to the start of the
+next, and fills that keep their order are left alone.
+
+## The search
+
+A chain of up to eight paths is found exactly, by dynamic programming over the
+subsets of paths: a state is the paths visited so far, the last one and its
+direction, about four thousand states for eight paths. The shared greedy
+chaining, `chain_segments_greedy_constrained_reversals_()`, does the same for two
+to four segments, which also orders up to four islands of a layer and the loops
+of a perimeter collection exactly. Either way the first path is no longer
+always the one nearest the start; with a free end, a path near the start can be
+worth leaving for last.
+
+Objects (`print_order` Default) and the tour of islands across objects are
+visited in the same order on every layer, so `chain_points_with_postprocessing()`
+orders them as a closed tour rather than an open chain. Up to ten points the
+shortest tour is found exactly by the same dynamic programming with the first
+point fixed; with a start point the tour then begins at the point nearest it.
+Larger sets take the greedy chain and alternate 2-opt, or-opt and crossing
+removal; or-opt moves runs of up to three points next to one of the eight points
+nearest an end of the run, found on the same grid as the chain's candidates.
+
+For longer chains, the search refines the greedy chain. On an island cut into many short pieces,
+such as infill without anchors, that chain can sweep away from the nozzle and
+come back for the rest with one long jump, which no local move below removes.
+So a nearest-next chain, going from the nozzle to the nearest free path end each
+time, is built too; when it is already shorter than the refined greedy chain, it
+is refined and used instead. Elsewhere it costs one grid query per path.
+
+`improve_chain_by_local_search()` sees the chain as a sequence of segments with
+an entry and an exit point each. Its cost is the straight distance from the
+nozzle to the first entry plus the distance from every exit to the next entry;
+the end of the chain is free. It applies three kinds of moves:
+
+- 2-opt reverses a run of segments, which flips each of them and replaces the
+  two links at the ends of the run.
+- Or-opt moves a run of up to three segments between two others, flipped or
+  not.
+- A run of any length that starts or ends next to the nozzle moves to the front.
+  Local search can settle on a chain that starts with a block of paths far from
+  the nozzle while the paths next to it sit in the middle, and moving that block
+  takes more than three segments at once.
+
+A move that would flip a segment that cannot be reversed is skipped, so such
+segments are only reordered.
+
+A move is tried only if every link it creates joins an end point to one of the
+32 end points nearest to it, which covers every move on a chain of up to 17
+segments, as most islands are; with 8 candidates the search missed most of the
+gain on grid-like patterns such as Triangles. The candidates come from a uniform
+grid of about two end points per cell, searched in rings of cells around the
+query. `KDTreeIndirect` visits its subtrees in a fixed order rather than the
+nearer one first, so a query for 32 points walks most of the tree, and on long
+chains finding the candidates would cost more than the search itself.
+
+The candidates of an end point are tried nearest first, and only while they are
+closer to it than the link the move would replace there. A 2-opt move that pays
+off creates a link shorter than the one it replaces at one of its two ends, so
+this misses no 2-opt move. An or-opt move is tried only while its new link is
+shorter than what taking the run out saves, which skips a few or-opt moves that
+would still pay off but cuts the search on long chains to a fraction.
+
+The search works through a queue of segments and applies the first move that
+shortens the chain around the segment it examines. After a move, only the
+segments next to a changed link are queued again. A new link can also make room
+for a run elsewhere that no segment next to it would try, so when the queue
+empties after any move, every segment is queued once more, and the search ends
+when such a sweep finds no move.
+
+Every move shortens the chain by more than `SCALED_EPSILON`, so the result is
+never longer than the greedy or the nearest-next chain and the search ends; a
+cap of 50 moves per segment only bounds its time. The search has no randomness
+and visits the segments in a fixed order, so the same input always gives the
+same G-code.
+
+## Cost
+
+Finding the candidates of an end point visits a few cells, and the nearest-next
+chain makes one such query per path, which only grows where the paths around the
+nozzle are used up and the chain jumps. Examining a segment tries at most a few
+hundred candidate links, usually only the nearest few, plus a scan of the chain
+for the move to the front when it is the first segment, and a move rewrites only
+the range of the chain it changes, so the search stays close to linear in the
+number of segments. Most islands hold a few to a few dozen paths; the cost shows
+on infill cut into thousands of pieces per island, such as dense infill with the
+anchors off. The straight joins only look at the line segments near a candidate
+join for crossings.
+
+## Limitations
+
+The search minimizes straight-line distance. It does not know which travels
+leave the infill area and retract under `reduce_infill_retraction`, nor the
+detours of `reduce_crossing_wall`, and a travel's time is not proportional to
+its length: a short travel is bound by acceleration, so its time grows about
+with the square root of its length. A chain that is shorter in total but trades
+very short travels for longer ones, or for ones past `retraction_minimum_travel`,
+can occasionally take a little longer to print.
+
+The end of the chain is free: it is not steered toward the next island or the
+start of the next layer. The regions of an island are chained one after the
+other, in region order, each from where the previous one ended.
