Hatched content — especially fills nested inside a block INSERT, such as a
title-block logo — plotted incorrectly: missing, mis-spaced, or with phantom
bars. Five related fixes make the PDF/plot output match AutoCAD.
1. Export block-internal hatch fills.
The export collected only hatches owned directly by the layout block, so a
hatch nested in a block INSERT was dropped and printed as bare monochrome
outlines. The insert-explosion the viewport already does is extracted into a
shared `exploded_insert_hatch_models()` and called from both the viewport
(`synced_hatch_models`) and the export (`paper_canvas_hatches`), so a plot
draws block-internal hatches identically to the screen.
2. Honour the hatch's own stored pattern-line spacing.
`hatch_model_from_dxf` re-derived pattern spacing from the name-matched
catalog entry x pattern_scale, ignoring the resolved line geometry the DWG
stores on the hatch. When a drawing was authored against a different base
spacing (imperial 0.125 vs the catalog's metric 3.175 for ANSI31), lines
came out up to ~25x too coarse and a dense fill collapsed to a few stray
lines. When the hatch carries its own line geometry it is now used directly
(identity scale/angle); the catalog path remains the fallback.
3. Fill far-from-origin pattern hatches.
`pattern_segments` clamped the ABSOLUTE scan-line index to
+/-MAX_LINES_PER_FAMILY. A fine-spaced hatch far from the pattern origin has
large-magnitude indices at both ends but a small span, so the clamp inverted
the range and emitted nothing — silently dropping the fill. Cap the line
count (span) instead of the absolute index.
4. Skip TEXTBOX boundary paths.
TEXTBOX boundary paths (flag bit 3) are text bounding-boxes AutoCAD derives
for island detection; they are never drawn or filled. Treating one as a fill
boundary painted its rectangle solid — a phantom bar. It is now skipped when
building the fill boundary.
5. Print white/ACI-7 hatch fills black on paper.
Hatch fills arrive adapted to the dark screen background, so a white/ACI-7
fill would vanish white-on-white on the sheet. Mirror the wire pass:
near-white/near-yellow -> black, near-cyan -> dark blue, matching AutoCAD's
colour-7-on-white plotting. Wipeouts keep their paper-white mask.
Adds `tests/block_hatch_export.rs` covering: block-internal hatch reaches the
export set, stored-line spacing is honoured, far-from-origin fills are not
dropped, and TEXTBOX paths are not filled.
- Reword the two new explanatory comments to describe the behaviour on its
own instead of citing another product.
- window_to_sheet: drop the unused window_min parameter (the caller already
derives its coordinate offset from the returned min-corner position) and fix
the doc comment to match what the function returns.

Ribbon:
- A ▾ selector at the right of the tab row picks the tool-panel density —
Auto (size to window), Full, Compact, or Collapsed. The choice is persisted.
It hides itself when the tool row is already tight, giving the cramped tab
row its space back.
Start page:
- The Recent Documents card is restyled to match the Supporters card
(rounded corners, 20px padding, matching title + colours).
- Its scrollbar no longer sits on top of the row ✕ remove buttons (a gutter
is reserved).
- A footer control sets how many recent files to keep: [-] an editable count
[+] with the max shown. Typing applies on Enter; an over-max entry snaps to
the max. The limit is persisted and enforced on load and on every open.
- The "Support on Patreon" heart is now the SVG icon instead of a font glyph.
Config:
- Add a shared `config::config_dir()` helper; the recent-files and status-bar
stores now go through it instead of each re-deriving the path. New minus.svg
icon for the stepper.

Pick a rectangular window in model space with the existing PLOTWINDOW command (now enabled in model space, previously paper-space only) and export it to a PDF at a chosen ISO paper size (A4-A0), orientation and scale (fit or ratio). The window is a hard clip boundary. Adds paper-size presets, a window-to-sheet transform, scale + clip support in the PDF exporter, and Page Setup controls (format/orientation/pick window).
XLine/Ray tessellate as +/-1e6 display segments (entities/ray.rs), and
both fit_all outlier defenses miss them: the IQR reject passes because a
construction line through the drawing has its centroid at its base
point, inside the consensus cluster; and the per-point lim filter passes
because local_extent_max is computed once at document load and stays at
the 1e9 default for drawings created fresh in-app. The far endpoints
then poison the bounds and the view fits +/-1e6, shrinking real
geometry to a dot.
Exclude XLine/Ray wires from the extents up front (AutoCAD likewise
ignores infinite lines in ZOOM Extents), falling back to fitting their
base points when the drawing holds nothing else.
Regression tests verified to fail without the fix (camera distance
3,000,000) and pass with it.

Adaptive tool-panel row now keeps degrading past the collapsed state instead
of overflowing:
- Panels still shrink from the right one at a time (full -> compact ->
collapsed). Once every panel is a collapsed button and the row still
overflows, each button drops its large icon to a small one (tight) together,
then the buttons are pulled together up to 8px per gap (reclaiming edge
padding) before anything is clipped.
- Tool-area height now tracks the tallest shown panel, so the ribbon shrinks
as its panels collapse; the measured height is reported for dropdown
anchoring.
- Tabs squeeze their inter-tab gaps shut before wrapping to a new row
(WrapFlow min_spacing_x).

When the window is too narrow for the full properties panel it now
collapses to a slim vertical "Properties" bar (its label drawn rotated 90°
on a canvas), freeing width for the viewport. Clicking the bar expands the
panel back out alongside the bar; clicking it again re-collapses
(props_expanded state + TogglePropertiesBar). Reuses the rotated-label bar
helper originally built for the Start page.

Rebuild the Start page as three parts — Recent Files (left), Welcome
(center) and Supporters (right) — that sit side by side while they fit.
When the page is too narrow for all three it falls back to a tab bar
(Recent Files / Welcome / Supporters) showing one section at a time, with
Welcome open by default (new StartSection state + StartSectionSelect).
The Recent Documents list moves off the left properties slot and into the
page itself. The Welcome column's button rows now flex-wrap, and the two
intro-video cards sit side by side, wrap to a stacked column when the
width gets tight, then shrink to fit the remaining height so they never
spill over the status bar. Trimmed the headline to just "Open CAD Studio"
(dropped "Welcome to" + the subtitle) and the "Release Notes" button, and
tightened the page's side padding.

- The Properties panel's Match button now shrinks to a small icon when the
panel is compacted (render_large gained a `compact` flag), so the panel
actually gets narrower and joins the from-the-right degradation instead
of jumping straight to collapsed.
- A collapsed Properties panel now shows its Match button as the
representative face: item_id recognises PropertiesGroup and
collapse_button renders its match_prop as a large tool.
- The undo/redo history controls are wrapped in PosReport, so their
dropdowns anchor directly below the button (and flip at the edge) like
every other dropdown, instead of falling back to the corner.
- Panel dividers are back: CollapsePanels draws a 1px line between adjacent
panels, skipped only between two collapsed panels.

The tool area no longer swaps every panel between a full and a compact
row together. CollapsePanels is now the whole tool area: it measures each
panel at full, compact and collapsed widths and degrades from the right —
first shrinking a panel's large buttons to compact icon columns one panel
at a time until the row fits, then (only if all-compact still overflows)
collapsing the rightmost panels to their ▾ flyout buttons. Left panels
stay full as long as possible.
Removes the global DensitySwap full/compact/collapse variant selection and
the now-unused build_tool_groups / tool_divider helpers.

All ribbon dropdowns (tool dropdowns, undo/redo history, and the layer /
colour / linetype / lineweight / style combos) and all status-bar popups
(scale, units, OSNAP, isolate, filter, customization menu, layout list)
now open directly at their widget instead of at a layout-estimated
position, and flip to the other side when the panel would cross a window
edge.
Each dropdown/pill widget is wrapped in a transparent PosReport that
records its screen bounds into a thread-local map on draw. The overlays
read those bounds:
- Ribbon: Ribbon::dd_anchor(id, panel_w, win_w) returns
(align_right, h_pad, top); position_ribbon_dropdown places the panel
below the widget, flipping right-aligned near the right edge.
- Status bar: popup builders take (pill_bounds, win_size) and call
popup::position_statusbar_popup / popup_anchor, opening just above the
pill and flipping left/right at the window edge.
The window size is now tracked (win_size, set on WindowResized). The old
layout estimators compute_dropdown_left / compute_layer_combo_left /
compute_prop_combo_left / compute_history_dropdown_left and
osnap_popup_right_offset are deleted.

Third stage of the adaptive tool area (shrink -> compact -> collapse).
When even the compact panels don't fit, DensitySwap picks a new
CollapsePanels widget that keeps a left prefix of panels inline and
collapses the rest to buttons; clicking a button opens the full panel as
an overlay flyout anchored below it (closes on outside press, mirroring
color_select's Floating).
A collapsed panel's button shows a live representative tool — the panel's
last-used tool (tracked per panel in Ribbon::note_panel_tool on every
tool click), defaulting to its first — rendered as a large icon. To
support this, render_small now also renders Large* items small and
render_large now renders plain Tool/Dropdown items large. Large dropdowns
render as icon + label + a bottom arrow strip via a shared
render_large_dropdown helper, used in both the full ribbon and collapsed
panels.
Ribbon dropdowns (tool dropdowns + undo/redo history) now anchor their
overlay directly below their widget at any size: a transparent PosReport
wrapper records each dropdown button's screen bounds into a thread-local
map on draw, and the overlays read it via Ribbon::dd_anchor instead of the
layout-estimating compute_*_left helpers.

DensitySwap now takes a third, narrowest variant: the compact panels
flex-wrapped (via WrapFlow) across as many rows as the width needs. The
tool area therefore degrades full -> compact -> wrapped as the window
shrinks. build_tool_row becomes build_tool_groups, returning fixed-height
panel elements so they lay out identically in a row or a wrap flow.
The tool bar is no longer a fixed TOOL_BAR_H; DensitySwap reports its
measured height into a cell and the ribbon dropdown overlays anchor at
tab_bar_height() + tool_bar_height() so they track the taller bar.
Second stage of the adaptive tool area (shrink -> wrap -> collapse).

Add a DensitySwap widget that renders the widest variant of the tool
area that fits the current width. The ribbon builds two variants via the
new build_tool_row(compact) helper: full-size panels, and a compact one
where LargeTool/LargeDropdown collapse to small icon columns (the
layer/properties/style combos always stay full). render_small now also
matches the Large* variants so they can be drawn small.
First stage of the adaptive tool area (shrink -> wrap -> collapse).

The Start tab, drawing tabs and the "+" button now live in a single
WrapFlow instead of a fixed-height Row, so they spill onto lower rows
when there are more tabs than the width can hold. Drops the fixed 30px
height and the trailing Fill spacer.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Add shared adaptive-bar widgets in src/ui/wrap_bar.rs:
- WrapBar: two-block bar (lead + optional Fill middle + trail). Fits on
one row, otherwise the trailing block drops below; with no middle both
blocks flex-wrap in their own row bands and stack so a wrapped lead item
never shares a row with a trailing item.
- WrapFlow: CSS-style flex-wrap row that spreads its items across as many
rows as the width needs.
Ribbon tab row: quick-access buttons and undo/redo are merged into one
WrapFlow; the tabs are a second WrapFlow. Dropdown overlays anchor to the
measured (possibly taller) bar height instead of a hardcoded 28px.
Status bar: the hamburger menu plus the Model/layout tabs form one
WrapFlow; the status pills form another. The layout-tab scroll arrows and
horizontal scrollable are removed in favour of wrapping.

Position the snap popup so the anchor point (by the Osnap button) is its
bottom-LEFT corner, opening up and to the right of the button rather than
extending left from its right edge. Pad by the anchor minus the panel
width, clamped so a narrow bar can't push it off-screen.

The snap popup used a hardcoded 4 px right offset, pinning it to the
window's right edge — but the Osnap button sits well to the left, with up
to ten pills after it (Space, Scale, Units, Transparency, Isolate, …).
Anchor it by the summed width of the pills that follow Osnap, honouring
the user's per-pill visibility. iced gives the view no real layout
metrics, so the pill widths are estimated (icon pills fixed, labelled
pills approximate); the popup now opens by the button instead of the
corner.

Two refinements to Parallel snap. The acquired reference now keeps a
point on the line and draws a ∥ marker there, so the user sees which line
the parallel is measured from. And dwelling on that same reference line
again removes it (toggle), matching how OTRACK tracking points clear;
dwelling on a different line switches the reference. Same-line detection
uses parallel direction plus perpendicular screen distance, so it holds
across zoom.
Refs #277
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Parallel snap did nothing — the type was in the osnap set, priority and
marker, but there was no logic behind it. Implement it: hovering a line
(or polyline segment) for a short dwell acquires its direction as a
reference; then while drawing from the last point, when the cursor runs
parallel to that reference the point locks onto the line through the last
point parallel to it, showing the ∥ marker and the alignment guide.
Curves (circle/arc/ellipse) are ignored — parallel to a curve is
undefined. Works with only the Parallel object snap on, independent of
OTRACK; the reference clears with the command's tracking state.

While a LINE's first point is a deferred circle tangent, the rubber band
stuck at the provisional pick point. Recompute the start on each mouse
move as the tangent from the cursor to that circle (keeping the side the
user first picked), so the tangent point on the first circle slides as
the cursor moves toward the second point.

A line whose FIRST point is a Tangent snap on a circle can't be fixed
until its direction is known, and a line tangent to TWO circles is their
common tangent — neither is resolvable at a single pick. A plain LINE
dropped the tangent object, so it drew a wrong line (TAN-TAN between two
circles).
Add an opt-in on_point_with_tangent hook (default ignores the tangent, so
every other command is byte-for-byte unchanged) and route the running
Tangent object through the point commit. LINE defers a first-point circle
tangent and resolves it on the next pick: against a second circle tangent
it picks the common tangent of the two circles (up to four — chosen by
the two cursor hits, so hovering selects inner/outer + side); against a
plain point it draws the tangent from that point to the circle.
last_point syncs to the resolved anchor. Common-tangent and point-tangent
math is f64 with perpendicularity unit tests.

The earlier #274 fix only corrected the tangent point's coordinate — the
point was still the circle edge facing the cursor, so Tangent snapped
like Nearest. Compute the true tangent from the point the command is
drawing from (from_point): the tangent point's radius is perpendicular to
the line from that point, giving two solutions at acos(r/|CP|) either
side of the C→P direction — take the one nearer the cursor. Falls back to
the facing point for a deferred tangent (object picked first) or a point
inside the circle. A line is tangent to itself everywhere, so the Line
case stays nearest-on-line. Covered by a perpendicularity unit test.

Catching a plain line-line Intersection re-runs extension_bases_screen to
draw the dashed guide(s) for an *extended* intersection (#247/#259). It
scanned every wire including tessellated circles, and a full circle's
chords point in every direction, so one almost always has an outward
extension that grazes the crossing — drawing spurious guide lines
radiating from nearby circles.
Skip closed curves (full circle / ellipse) in that scan, identified by
their Quadrant snap hints (arcs never carry them, so arc extension guides
are unaffected).

A user-defined hatch (angle + spacing + optional cross) carries the
placeholder pattern name "_USER", which isn't in the predefined catalog,
so it fell to a fallback that forced every one to flat horizontal lines
at the wrong spacing — ignoring the angle, the spacing and the double
flag.
Build base line families (angle 0, plus 90 when `is_double`) with unit
perpendicular spacing and let the HatchModel's existing angle_offset
(= pattern_angle) and scale (= pattern_scale) rotate and space them, the
same way predefined .PAT patterns are applied — so the angle/scale is
applied once, not doubled. Verified against the sample (0°/30°/90°-cross/
315°-cross at spacing 5/10).

Two object-snap fixes:
- Tangent on a circle built the snap point as
`(cx + r·nx, cy, cy + r·ny)` — the y-offset landed in Z and Y was stuck
at the centre, so the tangent point sat at the wrong place. Build it as
`(cx + r·nx, cy + r·ny, cz)`.
- Endpoint snapped to a full circle / ellipse: for tessellated curves it
snaps the first/last point, but a closed curve's first/last is a seam,
not an endpoint. Skip Endpoint for closed curves — identified by their
Quadrant snap hints, which arcs never carry — so arcs still snap their
real endpoints.

Skip re-rasterizing an unchanged frame (per-viewport render signature →
re-blit the cached resolve texture) and suppress the full-screen hatch
pass while navigating, rendering hatches once on settle. Reviewed:
signature covers every pixel-affecting input, per-viewport caches are
isolated, LOD settle timing renders + caches the full-quality frame, no
busy-loop. Targets #258.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The batched hatch pass evaluates its fill procedurally per fragment — a
point-in-polygon test over the whole boundary plus the pattern test, with a
`discard` that disables early-Z. When the view sits inside a hatch its quad
covers the screen, so panning / zooming re-runs that full-screen shader every
frame (~40 ms/frame on a hatch-heavy plan) even though the rest of the scene
is cheap — the wire pass and CPU prepare are negligible by comparison.
Suppress the hatch pass while the view is actively panning / zooming /
orbiting, detected from `camera_generation` plus a short settle timer
(`Scene::navigating_lod`), and fold that state into the render signature so
the moment the view settles it renders hatches once and the scene-render
cache holds that full-quality frame. A brief `is_settling` subscription keeps
requesting frames just past the settle point so the hatched frame renders
even when no input event would otherwise fire. Mirrors AutoCAD's adaptive
degradation. The paper sheet keeps its fills.
Every cursor movement over the viewport re-rendered the entire GPU scene
(all wires, hatches, meshes) even when nothing visible changed: iced redraws
the whole window on each input message, and the shader's draw/prepare/render
runs every time. On large drawings one such redraw exceeds the frame budget,
so moving the mouse or panning stutters — and it gets worse the bigger the
drawing.
The pipeline already resolves each frame into a persistent, clip-sized
resolve texture and blits that to the surface. This hashes the inputs that
determine the rendered image (camera uniforms, geometry/selection
generations, wire content id, render-mode flags, clip size, live preview
coordinates) into a per-viewport signature. When a frame's signature matches
the previous one the image is pixel-identical, so `prepare` skips the buffer
uploads + per-frame scissor/LOD recompute and `render` skips passes 1-7 plus
the MSAA resolve, re-blitting the resolve texture instead. A pure cursor move
becomes a single fullscreen blit rather than an O(N) re-rasterization.
The ViewCube is excluded from the signature (it renders in its own always-on
pass) so cube hover still tracks while the scene is cached. Any real change —
edit (geometry_epoch), select/hover (selection_generation), camera move or
render-mode toggle — differs the signature and forces a full render, so
nothing goes stale. Navigation still renders every frame (the view genuinely
changes); this targets the wasted re-render on cursor-only movement.
`orbit` revolved the target around the pivot as
`p + (delta * (self.target - p).as_vec3()).as_dvec3()`, casting the
target-to-pivot offset to f32. For a large model that offset is
extent-scale (the cursor can sit far from the view centre), so the f32
cast quantized it — nudging the whole view a fraction of a unit each orbit
step regardless of the drawing's origin. Do the revolve entirely in f64.

Every pan/rotate on a large drawing jerked once at the start of the
gesture. Instrumentation traced it to `paper_sheet_wires_arc` re-running a
full ~300 ms tessellation of the whole model block on the first hit-test
after each camera move.
`entity_wires_arc` (the pick/snap source in Model layout) delegated to the
camera_generation-keyed, view-culled `paper_sheet_wires_arc`. A camera
move bumps `camera_generation`, so the next hit-test cold-missed that cache
and re-tessellated every visible entity — O(visible), which is why the
jump grew with on-screen object count and shrank when zoomed in. The GPU
render was unaffected (it holds the separate camera-independent
`model_static_wires`), so only that one CPU frame stalled and the
accumulated mouse motion applied at once, reading as a jump.
Point the Model pick path at the same resident static set the render holds
(keyed on geometry_epoch only). Pick wants every entity, not a view-culled
subset, so this is also more correct — off-screen entities stay pickable —
and it never re-tessellates on a camera move.

Opening an xref-heavy drawing froze for ~22s before the first frame.
`synced_hatch_models` walked every INSERT and called
`explode_from_document()` to scan the result for hatch fills — but explode
CLONES every child of the block, including 3D solids that each carry tens
of KB of SAB geometry. Clinic.dwg's five xref INSERTs each reference a
discipline block of thousands of solids and no hatch, so this materialized
~25000 solid clones (~1 GB) on every open just to find zero hatches.
Add a memoized `block_contains_hatch`: a read-only scan of the block's
entity types (recursing nested INSERTs, cycle-guarded) that skips the
explode for blocks containing no hatch, transitively. Blocks that do hold
a hatch still explode exactly as before, so the hatch set is unchanged.
Hatch build for Clinic.dwg drops from ~21.7s to ~0.02s, cutting the total
open-to-first-frame time from ~25s to ~5s.

Pull in acadrust 4d51947, which makes SatDocument::record() an O(1) hit
instead of a linear scan. Tessellating an ACIS-heavy drawing was
O(records²) per solid; this drops the post-load mesh build for Clinic.dwg
(~9900 xref'd solids) from ~2.2s to ~0.85s of parallel tessellation, with
identical geometry.

`resolve_xrefs` parsed each xref DWG/DXF one after another, so opening a
drawing that references several large discipline files paid the sum of
their parse times. Split into two phases: parse every file in parallel
(each `load_file` is independent and never touches the host document),
then merge the parsed results serially in the original block order (merge
mutates the host doc, so it stays sequential and deterministic).
Resolving Clinic.dwg's 5 discipline xrefs drops from ~4s to ~2.1s with an
identical result (5 loaded, 0 dropped, same entity count). The speedup is
sub-linear because parsing is memory-bound (each file decompresses ~95 MB
of SAB geometry), not because of the serial merge.

Opening a drawing that xrefs several 3D-heavy DWGs (e.g. Clinic.dwg with
5 discipline files) took ~137s, effectively all of it inside the DWG
parser's AcDs SAB blob extraction.
Bump the acadrust pin to ceef045, which bounds the AcDs end-marker search
so a missing marker family no longer scans the whole buffer per record.
Total xref resolve for Clinic.dwg drops from ~97s to ~4s.
Also make the post-xref mesh pass incremental: the host solids were
already tessellated by the background loader and the merge assigns fresh
handles to every imported entity, so `populate_missing_meshes_from_document`
keeps the cached host meshes and tessellates only the merged xref solids
instead of clearing and rebuilding the whole document.

Extension-driven acquisition (OTRACK off) acquired any dwelled snap
point, including the extension foot the cursor paused on while tracing an
extension. Each such spurious acquisition filled the 4-point buffer and
evicted, oldest-first, the endpoint the user had actually acquired — so
after a few pauses its + marker and its extension disappeared.
Restrict Extension-driven acquisition to real segment endpoints (points
with an incident edge); midpoints, centres, intersections and extension
feet are ignored. OTRACK still acquires any snap point.

Extension snap extended every segment's line in the whole drawing, so in
a larger project an extension foot was live almost everywhere and the
cursor snapped to it constantly.
Extension now behaves like a temporary tracking point: an endpoint must
first be acquired by dwelling on it, and only then does that segment's
line extend. Acquisition — and the tracking-point marker — is active
whenever OTRACK is on OR the Extension snap is on, so Extension works
independently of OTRACK's on/off state (and is not tied to POLAR). Both
the per-segment extension and the extended-intersection candidates are
gated on an acquired endpoint, and the whole scan is skipped when nothing
is acquired (the common case), keeping large drawings responsive.

Mesh entities (PolyfaceMesh / PolygonMesh / SubD Mesh) could only be picked
on their thin edges — click_hit tested wire segments, and the solid face pick
only covers ACIS solids. When no edge is close, click_hit now also tests the
mesh's fill_tris with the same projected-triangle containment mesh_click_hit
uses for solids, so clicking a mesh's surface selects it, front-most first.
Edge proximity still takes priority.

PolyfaceMesh and SubD Mesh faces were fan-triangulated from vertex 0, which
is only valid for convex faces. A concave face (e.g. an L-shaped / notched
n-gon) fanned into triangles that spill outside the outline — spurious
"triangles that shouldn't be there" that covered neighbouring geometry and
its edges. Replace the fan with an ear-clipping triangulator that projects
the planar face to 2D, respects its winding, and clips only real ears, so
concave faces triangulate to exactly their own area. Convex faces (and the
cylinder-cap n-gons) are unchanged in result. Falls back to a fan for a
degenerate / self-intersecting polygon.
Verified on Annotation-2D-Mesh-Solid-BIM.dwg (concave 5-/6-gon mesh faces)
and by a unit test: a concave L-hexagon triangulates to n-2 triangles whose
total area equals the polygon's, with no overshoot.

Autocomplete suggestions came only from all_registered_command_names() —
the compile-time inventory registry returning &'static str — so
runtime-loaded plugin commands could never appear. Typing a plugin's
command prefix (e.g. `LS_`) showed nothing even with the plugin loaded
and its ribbon tab active; dispatch worked, only discovery was blind.
Collect each enabled plugin's ribbon ToolDef command ids plus its
manifest command_prefixes into a dynamic candidate pool
(OwnedRibbonGroup::command_ids → PluginManager::command_names →
plugin_command_names), refreshed in rebuild_ribbon_modules on startup
load, settings reload, and every enable/disable toggle. ranked_matches
now merges this pool with the static registry and returns owned strings.
A plugin.toml `commands = [...]` list for sub-verbs with no ribbon button
(e.g. LS_AUTOLABEL) stays a follow-up — it's a plugin-API surface change.

Picks up the acadrust change that writes xref blocks as external
references instead of serializing their resolved contents as owned
entities. An xref attached with XATTACH now survives a save + reopen as
a reference instead of being bound/exploded into loose objects.

The Layer Manager table and the ribbon's quick layer dropdown both
showed layers in document (insertion) order. Default the panel sort to
Name so both list layers alphabetically; a header click still re-sorts
by any other column. `apply_sort` reorders the panel's layer vector in
place, which the ribbon dropdown reads, so one default covers both.
With alphabetical ordering a freshly created layer can land anywhere in
a long list, so give the table scrollable an id and scroll its row into
view after creation, keeping the rename prompt visible.
Closes#270, closes#271

A rectangle's opposite corner is entered through Width/Height dynamic
fields, whose sign is taken from the cursor quadrant on commit. Typing
"50,50" is a cartesian coordinate pair, not two cursor-signed
dimensions, but the comma advance kept the Width/Height roles so the
committed corner mirrored into whatever quadrant the cursor sat in.
Key off `dyn_user_reshaped` (set only by `,`, never by Tab) to treat a
comma-separated entry as a literal cartesian coordinate for every field,
in both the point resolver and the live dyn-box display. Tab-separated
entry still reads as signed Width/Height dimensions.
Closes#269

view_world_aabb built a world-XY cull rectangle from the camera target and
ortho size without checking the view angle, so in a tilted / 3D view it
produced a top-down box that does not bound the on-screen footprint. That
box culls the pick wire set (while the render holds the full set via the
static hold), so a mesh running partially off-screen fell outside the box
and became unselectable — by edge or by face — even though it still
rendered. Top views were unaffected (the box is correct there), and 3D
solids pick through their mesh AABBs (not this wire set) so they never
showed it.
Return None for tilted views (fwd.z.abs() < 0.999), matching view_cull_aabb,
so no world-XY cull is applied and the pick reaches every on-screen wire.

Mesh (PolyfaceMesh / PolygonMesh) outline edges are drawn through the wire
pipeline, whose shader pulls each wire toward the camera by
draw_depth * DRAW_ORDER_BIAS (0.001) for 2-D draw-order layering. Every
entity gets a draw_depth in [-1, 1], so a mesh's edges were pulled forward
too — and when the mesh's depth extent projects to less than the bias (a
small or distant mesh), its hidden back-face edges peeked through its own
shaded fill. Solid feature edges use the mesh shader, which has no such
bias, which is why only meshes showed it and why adjusting the fill's depth
bias had no effect.
3-D mesh outline edges are real geometry occluded by true depth, so force
their draw_depth to 0 (they are already grouped as `mesh_edge` in
upload_wires). They now occlude exactly like solid edges.
