A SOLID's filled quad and a dimension/MultiLeader text background are flat 2-D
overlays that should draw in wireframe and shaded alike, but face3d_gpu
classified fills by `!fill_tris_low.is_empty()` — and a 2-D fill at UTM scale
carries a double-single low residual for precision just like a real 3-D mesh
face. So the arrowhead fill and the "5;8" cyan text background were routed to
the 3-D buffer and only appeared in shaded mode, vanishing back to nothing on
return to wireframe.
WireModel now carries an explicit `fill_is_3d`: true only for a real surface
(PolyfaceMesh / PolygonMesh face, set in the tessellator), false for every flat
overlay fill. face3d_gpu classifies on the flag, so 2-D fills stay in the
always-visible buffer while keeping their low residual (and UTM precision).
Verified on budweiser: the `_BoxFilled` arrow SOLID and the dim '5;8' MTEXT
background both tessellate with fill_is_3d = false.

Selection tested a flat 8 px radius around each wire's centreline and
nothing else, so two things the user can see were not pickable.
A wire renders as a band `line_weight_px` wide, so pick now widens to that
rendered half-width via `pick_tolerance_px`, mirroring the wire shader's
`select(0.5, half_width, lwdisplay_enable)`. Behaviour is unchanged for
every standard weight (the widest, 2.11 mm, renders 7.97 px half-width —
just under the 8 px threshold); this keeps the two sides from drifting
apart if the display boost in `lineweight_to_px` ever changes.
Entities extruded by a DXF thickness draw their wall as four edges with
nothing in between, so the interior was a hole the cursor fell through.
WireModel gains `pick_tris`: triangles hit-testing treats as solid and the
renderer never uploads. Kept apart from `fill_tris` because that channel
reaches the GPU, and a wall that rendered shaded would change how every
thickness drawing looks. Ranked below `fill_tris` — those are drawn, these
are not, so where they overlap the drawn face is what the user means.
Walls are dropped when a wire is projected into a floating viewport:
`points` are reprojected and clipped into paper coords there, so cloned
model-space triangles would hit-test at a model-scale offset. Extruded
entities stay selectable by their edges, which do get projected.
The wall loop runs on every hover that misses everything else, so it
rejects on the wire's AABB first — an extruded circle is ~128 triangles
and a drawing full of thickness would otherwise project every wall on
each mouse move.

MLINE dashed elements were fully CPU-expanded (apply_along) — one wire per
dash — to keep the parallel lines in phase. Move pure-dash elements onto the
GPU dash shader and end-align every element to the multiline's centre-line so
they share one interior phase.
- wire_distances now accumulates arc-length from the double-single (high+low)
points, so the dash phase stays precise at UTM coordinates. f32-high-only
deltas quantised ~0.1 there and drifted the parallel lines apart — the
original reason MLINE dashes were CPU-side.
- New WireModel.dash_align_end carries a shared begin/end dash length. The
shader uses it as align_end for every parallel element (the interior phase
depends on align_end, not the wire's own length) while align_total stays the
element's own length, so each still ends on a dash at its own endpoint.
- MLINE tessellation derives that length once from the centre-line, routes
pure dash/space/dot elements to the GPU pattern and text-bearing elements to
apply_along.
- apply_along gained an "A"-type mode (shared reference length): a solid
begin/end dash and a phased interior, so its dashes — and embedded text —
line up with the GPU-dashed sibling elements instead of tiling from start.
Pure-dash MLINEs now cost one WireModel + pattern per element instead of N
segments; single (non-MLINE) entities keep the from-start tiling unchanged.

DET pipe walls now carry the stroke pattern (dash_from_start), which
tiles from each wall's own start vertex and skips the A-type end
alignment that was force-lighting a solid dash under the end symbol.
Two rendering fixes on top:
- Dedup the host polyline's vertices before offsetting the walls. Some
DGN pipe polylines carry trailing duplicate end vertices; a zero-length
segment gave offset_xy a degenerate normal, leaving that vertex
un-offset and folding the wall down to the centre line. The two walls'
fold segments met at the centre and drew a spurious line linking them.
- Re-key the symbol (end circle / half-ellipse) wires to the host handle
so the whole pipe picks and selects as one entity instead of the
symbols acting as separate phantom entities.

Multilines were drawn with a fixed ±scale/2 two-line guess in the entity
colour, ignoring the MLINESTYLE entirely, so a drawing's custom style (per-
element offsets, colours and linetypes) was lost — a red/yellow multiline
rendered as a white box.
- mline.rs: resolve the MLINESTYLE (by style_handle, then name) and build one
parallel line per element from its offset x scale + justification shift.
- tessellate.rs: special-case MLINE (like Leader) to emit one WireModel per
element in the element's own colour, CPU-dashing every element through
apply_along so the parallel lines stay in phase.
- linetypes.rs: render a drawing's OWN complex linetypes (embedded text/shape),
document definition first and the bundled .lin catalog only as a fallback, so
a file-defined text linetype like PLYN shows its text.
- Run the dash/glyph layout in a local frame (f64 origin subtracted, re-split to
double-single after) so spacing stays precise at UTM coordinates, and pass
tracking = 1.0 so embedded text keeps its letter spacing.
Cargo.lock pins acadrust to the MLINE->MLINESTYLE handle-link reader fix.

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.

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).

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.

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.

Relocate three root-level modules into io/, where they belong by concern:
- update_check.rs -> io/update_check.rs (its own doc-comment notes it
mirrors how crate::io wraps blocking calls in async).
- patterns.rs, linetypes.rs -> io/ (standard resource catalogs parsed
from asset files and populated into the document — IO-shaped work).
Fix the moved files' include_str! paths (one level deeper), add the
mod declarations to io/mod.rs, drop them from lib.rs/main.rs, and
re-point all crate:: references to crate::io::. No behavior change.

Text elements previously rendered as hollow wireframe outlines and sometimes
fell back to the wrong system font due to case-sensitive exact matching. Also,
the viewport background grid drew on top of solid entities.
Case-insensitive and partial-name fallback matching (e.g., mapping "arialn"
to "Arial Narrow") is now added to `sysfont::canonical_family_name`, ensuring
text resolves to the correct installed system font.
TrueType font contours are now triangulated into solid fills (`fill_tris`)
using `lyon_tessellation` in `ttf_glyph.rs`. To prevent the GPU from misclassifying
this 2D text as a 3D mesh (which broke flat shading), text tessellation splits
the output into separate outline and fill `WireModel`s.
The background grid is extracted from `SelectionCanvas` into `GridCanvas` and
moved beneath the 3D viewport to ensure proper layering. Finally, `DepthBiasState`
is enabled on all face/fill pipelines to apply a polygon offset, perfectly
resolving Z-fighting between coplanar wireframe lines and solid faces.
Table / PolyfaceMesh / greek-text / mleader-background fills go through
the face3d pipeline; their vertices were single f32 and quantized at UTM
scale. WireModel now carries a fill_tris_low residual (filled by the
tessellate Lines path), Face3DVertex gains position_low (location 3), and
face3d.wgsl reconstructs the eye-relative position from the pair. 3DFACE
quads built from key_vertices use a zero residual (no low source).

Foundation for double-single positions: WireModel now carries an
index-paired f32 residual buffer (`points_low`) next to the existing
`points` high half. Empty means "all-zero residual", so every existing
constructor (interactive draw, previews) is unchanged in behaviour;
tessellation from CAD f64 will fill it in the next steps so vertex
precision survives at UTM-scale coordinates.

Move the 30 flat modules under src/scene/ into six folders by role:
convert (entity→geometry), text (fonts/shaping), model (render models),
pick (hit-test/selection/grips/xclip), view (camera/transform/render),
cache (block + property caches). pipeline/ is unchanged.
Full path migration — all `scene::X` references become
`scene::<group>::X`, no compatibility re-exports. render.rs items that
were `pub(super)` (parent was scene) become `pub(in crate::scene)` to
keep their original scene-wide visibility.
No behavior change; build and tests are green.
