A legacy leader's Lines & Arrows / Text / Fit rows are now editable
per-object overrides of its dimension style, stored in the standard
ACAD_DSTYLE XDATA record (new src/entities/dim_override.rs codec). Arrow
block, arrow size, dim-line lineweight, text offset, vertical text
position and overall scale each prefer an override over the style; the
renderer honours arrow size / block / overall scale and the dim-line
lineweight, so an edited leader redraws at its new arrow and weight.
XDATA edits go through a new dispatch::set_entity_xdata, which registers
the application in the APPID table (the DWG writer drops records for an
unregistered app) and drops that app's stale verbatim EED block (which
otherwise wins over the structured record on a DWG save), so edits and
clears round-trip. The hyperlink editor moves onto this path too.
Dim-line colour stays read-only: it would live in the leader's
override_color, which the file layer doesn't serialise, so making it
editable would silently lose the pick on save. Picking "Closed filled"
writes an explicit null-handle arrow override rather than clearing, so
it sticks even when the style's arrow differs; an unparseable numeric
entry is ignored instead of wiping the stored override.
Note: the DXF entity writer only emits XDATA for hatches, so these
overrides (and hyperlinks) currently persist on DWG save but not DXF —
an acadrust-side gap to close separately.

The General-group Hyperlink row becomes an editable text field; committing a
value writes the standard PE_URL XDATA record (an empty value clears it). Adds
scene::view::dispatch::set_common_xdata, which rebuilds an entity's XDATA to
replace or remove a single application record — ExtendedData only appends, so a
plain add_record would leave a stale duplicate the reader would pick first.

Render: annotative-ness is resolved centrally in scene::annotative::is_annotative
(per-object context dictionary, legacy XDATA, or annotative style) so the bake and
the properties panel agree. Text, dimensions, tables and blocks now display at the
current annotation scale in model space. An annotative block scales as one uniform
unit about its insertion point — its internal geometry and attributes are carried by
that scale instead of being scaled individually, fixing the block-attribute size
regression. Tables scale their column/row/margin geometry.
Properties: the handle- and flag-backed rows are now editable pickers — MLEADER
multileader style / text style / arrowhead / leader linetype, General Material, and
Plot style (named plot-style mode only; the color-dependent mode stays read-only,
which is correct). A picked name is resolved back to its handle in the update loop,
where the document is in scope. Annotative Yes/No and the annotation-scale row are
shown per object.

Match the entity Properties panels to the standard CAD layout and
web-verified behaviour:
- Text: combined Justify (horizontal x vertical) dropdown; Position and
Text-alignment rows become editable/grayed by justification; drop the
Annotative-scale row.
- MText: combined Justify; editable Direction, Line space distance
(back-solves the factor) and Line space style; Defined width/height
gated on column mode.
- MLeader: regrouped to match the palette - drop the Leader Structure
group (fold landing rows into Leaders), gate Text vs Block on content
type, full 9-value attachment label set, resolve handle-backed rows
(style, text style, arrowhead, linetype) to names.
- Leader: Lines & Arrows / Text / Fit are resolved from the dimension
style (arrowhead, arrow size, dim-line lineweight/colour, text gap,
vertical text pos, overall scale); Current Vertex navigator; combined
Type; Geometry group after General; no 3D-Visualisation group.
- General: rename "LT Scale" to "Linetype scale"; show ByLayer
transparency by name. Add shared num_prop helper for conditionally
editable numeric rows.

Text and dimensions vanished on a text-heavy, multi-font DWG. The global
SDF glyph atlas was a fixed 1024² page shared across drawings; once full,
pack() returned None and every further (font, char, bold) glyph was
silently skipped — so late-baked glyphs (dimension text especially) never
rendered.
Initialise the atlas at 2048² (covers real multi-font/CJK drawings with
no growth, so no stale UVs) and add a grow_height() fallback that doubles
height, appends zeroed rows, rescales cached entries' V/solid_uv and marks
the texture dirty (up to MAX_ATLAS_PX = 8192) rather than dropping glyphs.

Files saved while a paper layout was active reopened in Model space
because the loader hardcoded the current layout to "Model" and never
consulted the space recorded in the file.
The active space is a standard part of the format and acadrust already
round-trips it: $TILEMODE (header.show_model_space) for model-vs-paper,
and the CTAB current-tab variable for the exact layout name.
- Read: on open, pick the current layout from CTAB (when it names a
layout that exists), else $TILEMODE (Model, or the first paper layout).
- Write: Scene::sync_active_space_to_document() mirrors the active layout
back into the document (show_model_space + CTAB). It runs from
set_current_layout, so every active-layout change — the status-bar tab,
the Layout Manager's Set Current, create / rename / delete, and
undo/redo — keeps the document in sync for the next save.
$TILEMODE is the guaranteed mechanism (read and written for both DXF and
DWG); CTAB refines the exact tab when the variable is present.

Completes the f64 migration on the CPU data path: the only f32 left now
is the GPU/render/screen layer, which is architecturally required (wgpu
vertex buffers and iced are f32; f64 vertices would double memory).
- EntityTransform::Rotate.angle_rad and Scale.factor are now f64 (the
transform was already applied in f64 around the DVec3 center, so this
only preserves the typed angle/factor). apply_standard_transform and
apply_standard_scale take f64.
- CmdResult::ExtrudeEntity.height and AlignSelected.{angle_rad,scale}
are f64; the EXTRUDE height parses as f64.
- defaults.rs (last-used construction values: circle radius/diameter,
rotate angle, scale factor, offset/fillet/chamfer distance, array
spacing/counts/angle) moved from Cell<f32> to Cell<f64>. Array counts
round-trip through u32 (exact below 2^53).
- Consumers in circle/array/fillet/offset/rotate/scale/align/solid3d and
dimension.rs rotate_point/scale_point follow. `as f32` is kept only
where a value feeds a WireModel rubber-band/ghost (the preview path is
screen-space f32).

Three commit helpers narrowed a typed/picked point back to f32 before it
reached the persisted entity, so the coordinate was quantized to the f32
grid (worse at large/UTM extents):
- Scene::create_block_from_entities took the base point as glam::Vec3, so
the block's local-space translation and the replacement INSERT's
insert point were f32. Param is now DVec3 (matching the sibling
define_block_from_owned_entities); the command_driver handler no longer
downcasts with as_vec3().
- The MTEXT and TEXT in-place editors stored `pos` as Vec3 and built the
committed insertion_point from it, quantizing a new label's position
and re-quantizing an existing one on edit. Both `pos` fields are now
DVec3.

The HATCH/GRADIENT/BOUNDARY commands built the persisted hatch through
the render-side boundary (f32 offsets from world_origin), and with a
zero world_origin that meant absolute f32 - so a typed boundary vertex
of 2000.8 was stored as 2000.8020, and at UTM scale the fill landed far
from its boundary.
HatchModel.boundary stays f32 (the GPU render contract). Added
HatchModel.boundary_wcs: Option<Arc<Vec<[f64;2]>>>, an exact absolute-WCS
boundary set only by the draw commands. Scene::add_hatch persists from
boundary_wcs when present (exact f64 -> DxfHatch), else falls back to the
f32 + world_origin reconstruction used by DXF-rebuilt hatches. manual_pts
is now Vec<DVec3>; make_hatch takes the f64 boundary, stores the exact
copy and derives the RTE render rep. The committed render model is
rebuilt from the DXF entity, so nothing renders the command model's f32
boundary. This also fixes command hatches mis-placing at large
coordinates (world_origin was [0,0]).

Rewrite the in-app MTEXT editor to run on acadrust's structured
MTextDocument model end-to-end: load via parse_mtext, edit a flat Cell
model, serialize via to_mtext_string. Retires the hand-rolled format-code
string handling, the parallel visible_spans parser, the composed_value
prefix, and the Edit-raw-code tab.
Selection and copy:
- double-click selects the word, triple-click selects all (click-counting)
- Ctrl+A selects all text
- Ctrl+C copies the selected text to the clipboard
Formatting:
- per-selection Bold/Italic/Underline/Overline/Strike/Case/Alignment
- Bold renders as a visibly thicker SDF pen, keyed (family, char, bold)
through the whole text pipeline; the resolved style font name is stamped
so the \f...|b1; code survives serialization
- per-selection font and color changes
- editor color dropdown reuses the Properties panel color selector
Global toolbar defaults (font/color/oblique/width/tracking) fold onto the
document as real span properties instead of a leading code prefix; a
trailing empty paragraph is preserved so Enter at the end keeps its line.

Two defects in the in-app MTEXT editor, both surfaced once the preview
text became visible:
1. Invisible preview text. After the SDF text migration, tessellate emits
glyphs as SDF quads on `text_verts` and leaves the polyline `points`
empty, but the editor preview draws on a 2D canvas that can't run the
SDF shader — so only the selection box showed. Add a `force_text_strokes`
parameter to tessellate: when set, TEXT/MTEXT run-groups also emit their
glyph outline strokes as points. The preview passes true (real stroke
font, aligned with glyph_boxes); every other caller passes false and
keeps SDF-only text.
2. Enter did not start a new line. mtext_type inserted a literal newline,
but the MTEXT layout only breaks on the `\P` code (a raw 0x0A is a break
only to the caret logic). Normalise every literal newline — from Enter or
a multi-line paste — to `\P`, so the line breaks and the saved value
stays standard.

show_viewcube was excluded from render_signature, so toggling a static (cached) view produced an identical signature — the frame was skipped and the last GPU cube pixels stayed as stale cache. Add vp.show_viewcube to render_signature so the toggle invalidates the cache and re-renders, clearing the cube. The 2D overlay is iced UI and re-laid-out correctly, which is why only it hid.
Prebaked hatch fills anchored each pattern family at its authored
base point minus world_origin. On UTM-scale drawings that offset is
~1e6, which broke the fill two ways:
- the shader consumes x0/y0 as f32, so ~0.5 m quantization shredded
the pattern phase; and
- it evaluated the pattern that far from its origin, where the
multi-family aggregate patterns (AR-CONC, AR-SAND, GRAVEL, ...) —
effectively quasi-periodic — dissolve from their interlocking
stones into scattered dashes.
Boundaries were unaffected throughout; they ride the double-single
relative-to-eye path.
Fold the origin's offset from world_origin down to a small,
coherence-safe remainder on a `spacing * 64` grid, applied as one
common fold so every family keeps the relative phase that forms the
stones. Because the origin grip / Origin X/Y edit shifts every base
point by the same delta, the sub-grid remainder tracks it 1:1, so the
grip still moves the fill; a grid crossing needs a full `spacing * 64`
drag and is never hit by realistic alignment drags.

Ortho and the running object-snap set were app-global (settings.txt only) and
Isolate/Hide was a session-only view state, so none survived save/reopen and
none were per-drawing. Bind all three to the file like AutoCAD:
- Ortho -> header.ortho_mode ($ORTHOMODE); running OSNAP <-> header
.object_snap_mode ($OSMODE bitmask) via a new SnapType<->bit map in settings
(osmode_from_snaps / snaps_from_osmode, round-trip tested). The header is the
per-drawing store, live state mirrors the active drawing: adopt header->live
on open and tab-switch, stamp live->header on save and when leaving a tab, a
fresh drawing inherits the current values, and SETVAR ORTHOMODE/OSMODE now
also update the live state. settings.txt stays as the boot/new-drawing
default; the per-file header overrides it on open.
- Isolate/Hide now set each entity's persisted invisible flag (DXF code 60,
which acadrust round-trips in DXF and DWG) in addition to the session set;
End Isolation clears it. The set is reseeded from invisible entities on load
and after undo/redo, the commands are undoable and mark the tab dirty. The
renderer already skipped invisible entities, so no render change was needed.

When the viewport got too narrow the top-left render-mode bar and the
top-right ViewCube overlapped. Hide them adaptively, measuring the render
bar's real width rather than guessing:
- Wrap the render bar in DensitySwap, which measures its natural width every
frame and swaps it for an empty spacer once it no longer fits the tile. Add
report_width0 so it publishes that measured width to render_bar_w.
- Compute viewcube_visible from that measured width: the cube shows only while
bar_w + gap + cube region fits. This one flag drives the ViewCube nav/UCS
widgets, the hover hit-test, and — threaded through build_viewports /
build_viewport_for_pane / viewport_data_for — the GPU cube itself, which
previously ignored the pane flag (show_viewcube was inst.active only), so
the cube stayed while its surrounding widgets vanished.
Result: the ViewCube gives way first, then the render bar once it too has no
room — no overlap, sized to the bar's real width (which varies with the
render-mode label, split buttons and tile count).

STRETCH picks its crossing window as two corner points. After the first
corner set last_point, Ortho/Polar constrained the opposite corner to an axis
through it, collapsing the window to a line and making selection impossible.
Add CadCommand::window_corner_pick(); STRETCH returns true for its two window
steps, and the viewport skips the ortho/polar (and OTRACK) lock for that point
in both the preview and commit paths — the corners are now free.
Also render the window like a normal box selection instead of a bare green
outline: add SelectionState::preview_box (a hit-test-free marquee), draw it
with the shared draw_marquee helper (green crossing fill + stroke), and drive
it from the command's new window_first_corner(). Cleared on command end.

Command previews (MOVE, COPY, ROTATE, SCALE, STRETCH, MIRROR, ARRAY,
PASTE, INSERT) build ghost WireModels via WireModel::translated/rotated/
scaled/stretched/mirrored, but those helpers moved only `points`, never
`text_verts`, and the ghosts' glyphs were never uploaded — so text
vanished (or froze at its source) during the preview, same root cause as
the grip-drag case.
Transform text_verts alongside points in all five helpers (shared
map_text_verts, reconstructing + re-splitting the double-single world
position), and gather preview_wires' glyphs into the per-frame
preview-text buffer in the render path. This covers every command
preview automatically. The grip-drag else branch no longer sets
preview_text explicitly (the render gather handles it); the grip-slide
fast path keeps its own scene.preview_text channel (empty preview_wires,
so no double-draw).
MIRROR honours MIRRTEXT: on -> true glyph mirror via mirrored(); off ->
readable relocation via translated().

Dragging text by a grip hid it until release. The dragged entity is
hidden from the base wire set and shown as a preview overlay, but its
SDF glyph quads (text_verts) were never uploaded for the preview, so
the text vanished mid-drag.
Add a per-frame preview_text GPU buffer (sibling to preview_wires). A
rigid whole-entity move of pure text (TEXT/MTEXT, Square insertion grip)
slides the drag-start glyphs by the drag delta instead of re-shaping the
run every move; reshape grips (MTEXT width), dimensions and wire
entities re-tessellate and feed the same buffer.
Also fold preview_text into render_signature: a pure-text slide leaves
preview_wires empty, so without it the scene-render cache froze the
dragged text at its first frame (grip moved but text stayed, then
jumped to place on release).

Three defects in ACIS curved-wall (cone-surface) tessellation, all seen
in a Villa Savoye model:
- Balloon: sample_ellipse_arc ignored the edge's own sense relative to
its curve (distinct from the coedge/loop sense). A reversed edge winds
the ellipse about the opposite normal, so evaluating P(t) with the
stored normal mirrors a short boundary arc across the major axis to the
far side of the circle. That poisoned the face's angular-span estimate
and swept the whole 2pi revolution, drawing a curved wall as a full
cylinder of the surface radius. Honour edge.sense() (negate the sin
term when reversed) so the arc traces its true vertices.
- Seam: the fallback sampler's angular_range used raw min/max of atan2
angles, so an arc straddling the +/-pi seam read as a 2pi span (false
full circle). Derive the arc from the largest angular gap instead.
- Gaps: truck's rsweep/triangulation degenerates to zero triangles on
some short-arc cylinders (profile through the local origin), leaving a
see-through hole while the rest of the solid renders. Fall back to the
bespoke parametric sampler for just that face, into the same body-local
buffers. Also scale tess_cone_face's angular divisions by the arc span
so a short arc isn't tessellated as densely as a full rim.
Verified against the model: ballooned walls become wall-sized, and a
sweep of all 528 solids shows no empty faces and no triangle explosion.

Opening a DXF whose active viewport is stored uppercase (*ACTIVE),
editing and re-saving produced a file with two full-window model-space
viewports — the file's own *ACTIVE plus a fresh *Active we add on save.
The reserved viewport name is case-insensitive, so the two didn't
collapse and other CAD apps drew them one on top of the other, which
read as the copied objects being linked / "reacting as one".
save_model_tiles_to_vports dropped existing active viewports with a
case-sensitive `name != "*Active"` filter, so an uppercase *ACTIVE
survived and sat next to the new entry. Route every *Active comparison
(save filter + camera/tile restore) through a case-insensitive
is_active_vport_name helper so the file's record is recognised and
replaced instead of duplicated.
Also bumps acadrust to #99f75fe (merged PR #1): the ASCII DXF writer now
emits shortest round-trippable floats instead of the full 16-digit
expansion, halving the round-tripped file size.

TEXTFILL 1 (default) fills TrueType text; TEXTFILL 0 draws it hollow
(outline only). Settable directly or via SETVAR, 0/1 or ON/OFF. SHX/LFF
stroke fonts are unaffected.
Reuses the existing stroke-SDF path: bake_glyph treats a TTF glyph as a
stroke (outline) field instead of a signed fill field when TEXTFILL is
off. Toggling resets the glyph atlas and re-tessellates text so quads
pick up the re-baked tiles. Persisted in user settings.

Restructure the plot dialog into a style-manager-style master/detail: a
left list of page setups plus a right settings editor. The list shows
<none> (defaults + PDF) and <previous> (the settings the dialog opened
with), then the drawing's layouts (*Model*, *Layout1*, …) and its
standalone named page setups.
- Named page setups live in the ACAD_PLOTSETTINGS dictionary
(src/scene/page_setup.rs: names/get/save/delete/rename, creating the
dictionary if absent); DWG round-trip verified.
- Toolbar New / Copy / Delete | Set current / Preview / Print. Selecting
a row loads it into the editor; Set current writes to the active
layout. Copy duplicates a layout or a setup into a new named setup;
Delete/Rename apply only to named setups.
- Scene::plot_settings_for(name) generalizes effective_plot_settings so
any layout's settings can be loaded; on open the settings are
snapshotted for <previous>.
- Default selection: model space → <none>; a layout → its own setup.

The batched path is the sole hatch renderer and has no family cap, yet it
was named hatch_batched_gpu while the old capped per-primitive renderer
kept the hatch_gpu / MAX_FAMILIES name — which reads as if visible hatch
fills are truncated at 16 families (they are not). Swap the names so the
active renderer is hatch_gpu.rs / hatch.wgsl and the legacy one, now used
only for wipeout masks, is wipeout_gpu.rs / wipeout.wgsl. MAX_FAMILIES now
lives only in the wipeout module. Pure rename; no behaviour change.

Snap and hover hit-testing scanned the whole model wire set every cursor move; a heavily block-instanced drawing explodes to millions of wires, so this stalled for over a second per move. Add a cached spatial grid (wire_grid) keyed on the geometry epoch and query only the cursor neighbourhood via Scene::hit_test_wires_near. Gate the O(in-range segments squared) intersection passes on the in-range POINT count, not the wire count — a handful of curved wires, each hundreds of tessellated points, blew the quadratic up while the wire count looked modest. Give zero-size entities away from the origin (POINTs) a real cullable AABB, and fall back to a block sub-wire's own world points when its entity bounding box is degenerate.

Dragging a model-tile pane_grid divider changed each pane's pixel size
every frame, and `ensure_depth_texture` recreated the depth + 4×MSAA +
resolve textures on any size delta. On Windows Firefox (WebGL2 → ANGLE →
D3D11) this per-frame texture realloc hangs the D3D driver — the same
hang class as the native DX12 lock in #120. Linux Firefox (native GL) and
Chromium/Edge tolerate the churn, which is why the freeze is specific to
Windows Firefox.
Round the depth/MSAA/resolve allocation up to a 128px grid and only
recreate when the rounded size changes, so a live drag reallocates at
most once per 128px instead of every frame. Geometry passes still render
at the real size into the [0,0,render] corner of the larger texture, and
the blit UV is scaled by render/alloc so it samples exactly the filled
region — visually a no-op on every platform.

The Current Vertex row is now a ◀ / ▶ stepper (new PropValue::Stepper)
showing "i / N". Stepping it moves the panel's focus through the
polyline's vertices — Vertex X/Y and the per-vertex start/end widths show
and edit the focused vertex instead of always the first — and the focused
vertex's grip is drawn hot (filled) in the drawing so it's visible while
navigating. Focus wraps around and resets to the first vertex when the
selection changes. Adds Area and Length to the LwPolyline Geometry group
(Polyline2D already had them). Applies to LwPolyline and Polyline2D.
The focused vertex is threaded to the per-entity property builder/editor
through a dispatch thread-local (like the curve-tolerance override), so
the PropertyEditable trait signatures are unchanged.

Copying and pasting a whole drawing froze the app. Three synchronous,
main-thread hot spots scaled with the full document rather than the
selection:
- Copy centroid did a linear document scan per selected handle
(wire_models_for / mirror_preview_parts), making copy O(H*N). Use the
document's O(1) handle index instead.
- The paste ghost translated every point of every clipboard wire on each
mouse move — O(points) per frame, which stalls placement of a huge
selection. Above a point budget, rubber-band a single bounding-box
outline instead (O(1) per frame).
- finalize_paste re-tessellated every solid in the document on each
paste. add_entity already tessellates pasted solids, so switch to the
incremental populate_missing_meshes_from_document.
Leaves just Material in the group. The shadow_flags entity field is
untouched (preserved on save); only the read-only panel row is removed.

Reorder the General group so Color precedes Layer. Remove the "Invisible"
row: the entity visibility flag (DXF code 60) is driven by dynamic-block
visibility states, not a manual per-object toggle — setting it from the
panel hid the object with no easy way to reselect it. The flag itself is
unchanged (dynamic blocks still set it, render/save still honour it, and
it stays settable programmatically).

Wide LwPolyline / Polyline2D fills only drew for entities directly in the
layout — the model-space loop skips block-internal ones, and the
block-explode fill pass handled hatches but not wide polylines. So a
polyline with a width nested in a block drew at zero width (its
centreline came from the wire path, the band fill never materialized).
Extend the block-explode fill walk (exploded_insert_hatch_models) to emit
wide-polyline bands at world position, gated by a new block_has_wide_poly
scan mirroring block_has_hatch, with a shared push_block_wide_fills helper
that resolves block-child colour inheritance and applies XCLIP.

The batched hatch path pre-triangulated every boundary on the CPU
(PR#300) with no cap on the resulting vertex buffer. A hatch-dense
drawing (13k solid-filled hatches) built a ~6.75 GB `hatch_batched.vertex`
buffer and panicked in `Device::create_buffer` (device max 256 MB), after
a long stall spent triangulating on load.
Drop the CPU triangulation and always draw each hatch as its AABB quad
(6 verts) with `poly_test = 1`, letting the shader resolve inside/outside
per fragment against the uploaded boundary — the path the shader always
kept as a fallback. The vertex buffer is now 6 verts/hatch regardless of
boundary complexity, so no drawing can overflow it. The interaction-LOD
flicker PR#300 addressed no longer occurs (OCS_HATCH_LOD defaults off).
Removes the now-unused hatch_tess triangulation module.

The main GPU render holds the resident (un-culled, camera-independent)
model wire set from `model_tile_wires_arc`, which called
`wires_for_block_culled` with `view_aabb = None` — the branch that bypassed
the per-entity tessellation memo. So every geometry edit re-tessellated
the whole model, even though `mark_entity_dirty` already drops just the
changed entity from the memo.
Give the resident set its own per-entity memo (`resident_tess_memo`),
separate from the camera-dependent `tess_memo` so the culled path can't
thrash it on zoom. Its guard depends only on annotation scale and
background (the resident set has no view cull or zoom LOD), so it survives
pan/zoom and a single-entity edit re-tessellates just that entity, reusing
every other entity's cached wires — on a large drawing, editing one object
now re-tessellates one object instead of the whole model.
Every `bump_geometry_no_blocks` site was audited to confirm it drops the
edited handle via `mark_entity_dirty` (or adds a new entity — a natural
memo miss); `bump_geometry` still clears both memos on structural change.
`OCS_NO_RESIDENT_MEMO` reverts to full re-tessellation as a kill-switch.

carries an explicit override and keeps it) — #301's fix, still correct for
the remaining stroke wires.
- block_cache emit_wire: the per-vertex analogue for SDF text — a glyph whose
colour equals the wire's base inherits the resolved colour; a glyph with an
inline \C / \c override keeps it. (Previously every block glyph was recoloured
with final_color, collapsing colour-split MTEXT.)
- tests/text_font_rendering.rs: restore the block colour-split regression test
(it had stopped compiling on main when expand_insert gained the InheritStyle
param) and adapt it — and drawable_point_count — to SDF text_verts, since
block MTEXT now renders as glyph quads, not colour-split stroke wires.
\C (ACI) / \c (true-colour) are parsed by acadrust (mtext_format
SpanProperties.color) → OCS InlineColor → the glyph's per-vertex colour.

External contribution by sLuCHa. A dimension draws from its baked *D block
(baked in absolute WCS); the in-drawing COPY re-points block_name to a
transformed copy (#161) but clipboard PASTE did not, so a pasted dimension
rendered at the source location (same drawing) or was missing (cross drawing).
Copy now snapshots each copied dimension's *D block into the clipboard
(dim_blocks); paste builds a fresh copy transformed by the paste offset and
re-points block_name — same- and cross-drawing alike, no orphan blocks.
Refactors out shared define_transformed_block / snapshot_block helpers
(behaviour-preserving).

External contribution by sLuCHa. Triangulates each hatch boundary once
(lyon even-odd, cached with the batch build) and rasterizes the triangles
instead of the per-fragment point-in-polygon test, removing the screen-fill
overdraw + boundary raycast that forced the flicker-causing interaction LOD
(now default off behind OCS_HATCH_LOD). Precision preserved (triangles in the
same world_origin-relative frame + RTE path); untessellatable boundaries fall
back to the old AABB-quad + in_polygon path (poly_test=1).

Two fixes for opening drawings with XCLIP'd blocks (crashed / mis-rendered
since SDF text became the default).
- block_cache emit_wire: the fill_tris/fill_tris_low length debug_assert
panicked in debug builds on a legitimate case — a Leader/dimension arrowhead
fill nested in a block carries fill_tris with an empty fill_tris_low (the
WireModel contract's "all-zero low" form, which the code already handles via
get().unwrap_or). Relax the assert to permit the empty case; a *partial* low
half is still caught.
- xclip clip_wires: also clip the SDF glyph quads. Block-internal text was
bleeding past the clip boundary (mixed batch) or vanishing (the tail retain
dropped empty-points wires). Now each glyph quad is kept/dropped by its
centroid vs the boundary (whole-glyph granularity), text_verts-carrying wires
survive the retain, and the pick-box AABB is recomputed from the surviving
glyphs.

SDF is the only text renderer now — the stroke path and its LOD ladder are
gone, and the remaining text kinds render as SDF glyph quads too.
- ATTDEF / ATTRIB: carry a GlyphRun so single-line attribute text renders as
SDF (multi-line already did via layout_mtext). Tolerance / complex-linetype
text already SDF.
- Remove `sdf_text_enabled()` (the OCS_TEXT_SDF flag / kill switch) and take
the SDF path unconditionally everywhere: tessellate Text arm (per-group by
GlyphRun presence), hit_test fallbacks, render gather, complex_lt, table,
mleader.
- Delete the text LOD ladder: tess.rs baseline/greek block and the
block_cache greek/baseline path (emit_greeked_text / emit_text_baseline),
plus the now-dead helpers text_baseline_points / text_greek_obb_tris /
text_obb_corners_native / mtext_line_count and the LocalWire
text_height_local / text_obb_local fields. All text is crisp at every zoom;
text entities are exempt from the sub-pixel stub cull.
- Fix a latent bug: block-internal SDF text was culled because its LocalWire
aabb_local was [0,0,0,0] (no points) — fold the glyph-quad extent into
aabb_local and exempt text_verts-carrying wires from the sub-pixel cull.
- Clear the pre-existing dead-code warnings (TextPlacement.elevation, TabKind,
MTextRunKind::Tab).

An in-app-created table (no baked *T### block) synthesised its cell text via
layout_mtext as stroke polylines — the last text path still rendering strokes
while SDF is the default (imported/baked tables already render SDF via the
recursive Text arm).
- tessellate_table: when SDF is on, build each cell's glyph quads from the
run-carrying layout and collect them into one text-carrying wire (per-vertex
cell colour, glyph-bounds AABB); the stroke/fill accumulation is the SDF-off
fallback. Mirrors the MLEADER SDF branch.
- tess.rs synthesized-table path: guard the whole-table AABB clobber on
(!points.is_empty() || !fill_tris.is_empty()) — matching the dim / mleader /
baked-block paths — so the empty SDF-text wire keeps its tight glyph-box AABB
and the pick box hugs the text instead of the whole table. Found by the
adversarial review pass.

Extend SDF text to the remaining text kinds and make the Text arm decide SDF
per group instead of per entity type.
- Text arm: a stroke group renders as SDF glyph quads when it carries a
GlyphRun (strokes suppressed); a run-less group keeps its strokes. TEXT /
MTEXT / dim / block / mleader are unchanged (all run-groups). A composite
Text object can now mix geometry + text: its run-less groups stay strokes and
its run-groups become SDF. The glyph-bounds AABB is hoisted so both the
bins-empty and bins-non-empty paths stamp it on the text wire.
- Tolerance: refactored to emit the feature-control frame (border, separators,
dividers) as run-less stroke groups and each cell's text as a run-group, so
the frame stays crisp geometry while the values/symbols render as SDF text.
- Complex linetypes: embedded LtSeg::Text renders as SDF glyph quads on an
extra text wire (glyph-bounds AABB) instead of stroke polylines.
- click_hits_all: include SDF text boxes so selection cycling steps through
text too, ranked after real geometry.

Flip `sdf_text_enabled()` to default ON: text renders as SDF glyph quads
(crisp at every zoom, no LOD, box-based snap/pick) for everyone. Set
`OCS_TEXT_SDF=0` to fall back to the legacy stroke path — a kill switch kept
in case a drawing or environment needs the old renderer. Off-screen text is
still view-culled per entity, so dropping the text LOD ladder stays bounded.

Render the MTEXT background (never drawn before — the flags were only shown
read-only in the panel) and make it editable.
- Text arm emits an opaque fill_tris rect behind the glyphs: flag 0x01 uses
the entity background colour, 0x02 uses the canvas colour (a wipeout-style
mask). Box = glyph bounds padded by (background_scale - 1) × text height.
- Text frame (flag 0x10) draws a closed rectangle in the text colour around
the same box.
- Threaded `bg_color` into `tessellate()` (+ all callers and the
MultiLeaderTess trait) so the mask can use the drawing-window colour.
- Properties: "Background mask" is a Off / Fill / Mask dropdown, "Background
color" is its own colour picker (independent of the entity colour — new
PropBgColor* messages; picking a colour switches to Fill mode), and "Text
frame" is a checkbox toggle. Edits re-tessellate so the change shows live.
Renders via the face3d fill path, so the fill shows with FILLMODE on (same as
MLEADER background fill); the frame is a stroke and always shows.

Rearchitect SDF text from a document-wide collector to per-entity
production during tessellation, so each entity owns its glyph quads and
composite/nested text is covered for free (no re-explosion, no per-frame
document walk).
- WireModel gains `text_verts`: glyph quads ride on the wire, so they are
cached by the tess memo, cloned on hit, and transformed by the block
expand loop exactly like `points`.
- Text arm (tessellate.rs) builds the quads when SDF is on and suppresses
the strokes; render gathers text_verts from the viewport wire set
(`gather_text_verts`, cached on wire content id) — the old collector is
removed. Covers model, dimension, table, block-internal and paper-sheet
text uniformly.
- MLEADER text (lays out via layout_mtext, not the Text arm) gets its own
SDF branch driven by the per-run GlyphRun.
- Pick box comes from the rendered glyph quads (true text extent), not
entity_aabb which mis-places the box for MTEXT; composite paths no longer
clobber the empty text wire's tight AABB (dim pick box hugs the text).
- Selection / hover highlight via a text-highlight overlay (upload_text_
highlight, keyed on selection_generation) mirroring the selected-wire
xray overlay; base glyphs stay neutral so a deselect leaves no stale tint.
- Debug: env OCS_TEXT_BOX draws each run's glyph-bounds rectangle.

Copy-paste (CTRL+C / CTRL+V) dropped dimensions. A dimension draws from
its baked *D block, whose geometry is in absolute WCS coordinates, and
the clipboard paste path added the dimension entity but never gave it its
own transformed block — unlike the in-drawing COPY, which does (#161). So
the pasted dimension kept pointing at the source block and rendered at
the original location instead of the paste point (same drawing), or had
no block at all (cross-drawing).
Capture each copied dimension's *D block into the clipboard, and on paste
build a fresh transformed copy of it and re-point the dimension's
block_name — for same- and cross-drawing pastes alike. Factored the
block-building out of clone_transformed_block into a shared
define_transformed_block, and the block snapshotting out of
capture_blocks into snapshot_block.
The batched hatch pass drew a screen-covering AABB quad per hatch and,
for every fragment, ran a point-in-polygon ray-cast over the whole
boundary plus the pattern test, with a discard that disabled early-Z.
Zoomed into a hatch the quad covers the screen, so the shader re-ran
per pixel every frame — the cost the PR #273 interaction-LOD worked
around by suppressing hatches during navigation, which made fills
flicker on and off while zooming.
Triangulate each boundary once (lyon, even-odd — same coverage as the
old in_polygon, islands/holes included) and rasterize those triangles
instead: no screen-filling overdraw, no per-fragment boundary test. The
fragment shader keeps the boundary test only on a per-instance fallback
path (poly_test == 1) for boundaries that fail to tessellate.
Tessellation is cached with the batch build (geometry_epoch) in local
space, so the double-single relative-to-eye precision is preserved.
With the fast path the interaction-LOD is no longer needed; it is gated
behind OCS_HATCH_LOD (default off) as a safety net for now.
The SDF text collector re-laid out every glyph of every text entity on
each frame (pan/zoom included). Cache the vertex list on the Scene keyed
by (geometry_epoch, annotation-scale bits) — it only changes when geometry
or the scale changes — so pan/zoom reuses it. Glyph baking happens on the
cache-miss path only; the atlas is a persistent global and the texture
upload is already gated on the geometry epoch, so cache hits skip both the
layout and any re-upload. No behaviour change.

With OCS_TEXT_SDF on, top-level text took the full path only at ≥5 px and
still drew greeked OBB rects / baseline lines when zoomed out — doubling
with the SDF glyphs. Force the text LOD height to None while SDF is on so
text always falls through to the full path, which is itself suppressed to
an empty snap-only wire; SDF then renders it crisply at every zoom.
(Block-internal text is unaffected — it is not collected for SDF, so its
wire/greek path stays.)
Verified in-app: zoomed-out SDF text stays crisp with no greek/baseline
double draw. Flag off: unchanged.

With OCS_TEXT_SDF set, text now renders only as SDF quads: the wire path
skips building glyph-stroke geometry (bins stays empty, so the existing
empty-wire branch still emits the insertion snap point). This removes the
double draw (strokes + SDF) and, as a side effect, fixes the long-standing
snap pollution (#276) — snapping near text no longer catches individual
glyph-stroke endpoints, only the insertion point.
Shared sdf_text_enabled() (cached env read) gates both the collector and
the stroke suppression so they stay in lock-step. Flag off: unchanged.
Verified in-app: TEXT/MTEXT/decorations render clean as single SDF, and
snap no longer hits glyph strokes. Click-pick on text is limited while the
flag is on (no stroke geometry) pending a text OBB pick box.
