Phase 4.1. Handle / u64 keys dominate the hot maps (block_defn,
hatch / image / mesh caches, draw-depth map, viewport wire caches);
the default SipHash is wasted work on integer keys. Alias the std
types to rustc_hash::FxHashMap / FxHashSet crate-wide so every map and
set — including the cross-module draw-depth map shared between scene
and the GPU pipelines — uses the faster hasher consistently.
Mechanical: no behavioural change. Constructors moved from ::new() to
::default() (Fx variants carry no RandomState). Build + 13 tests green.

DRAWORDER now affects rendering immediately (bump geometry epoch so the
sort cache rebuilds) and front/back anchor to the block's full effective
sort range instead of only existing table entries, so bring-to-front
actually lands on top. The render fallback sorts table-absent entities by
their own handle.
Draw order now applies across entity types, not just within a type. A
per-entity draw-order rank (SortEntitiesTable override or own handle,
ranked per block) is encoded as a small signed clip-z bias in the wire,
hatch, image, and 3DFACE pipelines. The shared LessEqual depth buffer then
orders fills, lines, rasters and 2D solids against each other regardless of
pass order — without touching model coordinates. 3D meshes keep real
geometric depth; wipeouts stay always-on-top.
Adds a Draw Order submenu to the viewport context menu (Bring to Front,
Send to Back, Bring Above/Send Under Object). The above/under items run an
interactive reference-object pick, then reorder the captured selection.

3D yüzeyleri (Solid3D mesh, 3DFACE quad, PolyfaceMesh/PolygonMesh face
tris) HiddenLine modunda renk yazmadan z-buffer'a yazıyor; ardından
kenarlar wireframe pipeline ile çizilince LessEqual depth testi
arkadaki segmentleri eliyor. 2D fill'ler (text greek, MultiLeader
arka planı) ayrı bir vertex buffer'a ayrıldı ve her modda renkli
çizilmeye devam ediyor.
- Face3DGpu: vertex_buffer artık 3D / 2D olarak ikiye ayrıldı
- mesh_depth_pipeline + face3d_depth_pipeline (write_mask=empty)
- RenderModeFlags.hidden_line + Primitive.hidden_line plumbing

Wireframe 2D/3D modlarında Solid3D meshlerini edge-only çizmek için
LineList topolojili bir mesh wireframe pipeline ve her üçgenin
(a,b),(b,c),(c,a) kenarlarına genişletilmiş ayrı bir index buffer
eklendi. PolyfaceMesh / PolygonMesh face fill'leri (fill_tris + dolu
points) wireframe'de gizleniyor; text greek / MultiLeader gibi 2D
fill'ler (points boş) etkilenmiyor.

Greek rects rendered through fill_tris went through the face3d 0.45
dim path; the pre-boost (color × 1/0.45) compensated only until clamp
hit at 1.0, leaving bright user colors washed out. The earlier outline
workaround dodged the dim but lost the filled box visual that AutoCAD
uses for "text lives here".
- face3d pipeline now skips the 0.45 dim when `wire.points` is
empty. PolyfaceMesh / PolygonMesh keep their dim (both points and
fill_tris populated); greek and MultiLeader background-fill emit
`points: vec![]` so they render at the literal color.
- All three greek paths (top-level, block-defn, MultiLeader) emit a
2-triangle filled rect instead of an outline / boosted fill.
- Greek rects are clamped to single-line height so 5-line MText
doesn't blow the box up to the full text-block height. MultiLeader
emits one rect per line — keeps the per-row visual hint.
- BatchEntry/StyleKey gain an `is_fill_only` discriminator so greek
batches never collide with regular wire batches; otherwise the
finalized WireModel could carry both points and fill_tris and
defeat the pipeline-side empty-points check.
Xref fade still applies to the resolved color via the existing
`fade_toward_bg` path, so xref greek stays faded as expected.

PolyfaceMesh and PolygonMesh were wireframe-only. They now render with
the same flat-color solid fill as Face3D entities.
- Add fill_tris: Vec<[f32;3]> to TruckEntity and WireModel
- PolyfaceMesh: fan-triangulate each face into fill_tris
- PolygonMesh: triangulate each grid quad into fill_tris
- tessellate.rs Lines branch: apply world_offset to fill_tris
- Face3DGpu::from_wires: collect fill_tris from all wires in addition
to Face3D key_vertices quads
- upload_face3d: pass all_wires so fill_tris are batched into one draw call
- fix: polyline arc center sign was inverted (- → +) causing arcs to render on the
wrong side in LwPolyline and Polyline2D
- fix: store glyph strokes in local space with f64 origin so world_offset subtraction
uses f64 precision; prevents blocky text at large UTM coordinates
- fix: Face3D fill darkened to 45% so edge wires are visually distinct from fill
- fix: wire batch vertex buffer chunked to 256 MB GPU limit (was panic on large files)
- fix: gpu_face3d_edges changed from Option<WireGpu> to Vec<WireGpu> to support chunks

acadrust Face3D encodes triangles by setting fourth_corner == third_corner.
The fill builder was emitting a zero-area second triangle for these cases.
Now checks the p2==p3 distance and skips the second triangle.

3DFACE entities previously created one WireGpu buffer per entity,
resulting in N separate draw calls per frame. For files with large
triangle meshes this was the dominant GPU CPU overhead.
New pipeline:
- face3d.wgsl: simple flat-color vertex + fragment shader (MVP only,
no quad expansion, no pattern distance computation)
- Face3DGpu: batches ALL Face3D entities into a single TriangleList
buffer (6 vertices per face, per-vertex color) — 1 draw call
- WireGpu::from_batch: merges N Face3D edge wire models into one
quad-expanded buffer for edge rendering — 1 draw call
- split_face3d_wires: separates face3d from other wires at Primitive
build time via document handle lookup (O(N), once per epoch)
Hit-testing via WireModel (CPU) is unaffected — face3d wires remain
in entity_wires_arc() and hit_test_wires() as before.
Before: N 3DFACE → N draw calls, N × 96 B/vertex WireVertex
After: N 3DFACE → 2 draw calls (fill + edges), 28 B/vertex fill
