Explains the stop-gap MAX_SEGS_PER_WIRE / MAX_TOTAL_SEGS limits added in
321433e, why they must be reverted, and the condition under which they
should be removed (Phase 1.3 CPU cull landed and verified).

Adds two-layer protection against large entities crashing the renderer:
- MAX_SEGS_PER_WIRE (100K): per-entity hard cap, excess segments truncated
- MAX_TOTAL_SEGS (3M): scene-level budget in upload_wires, excess wires skipped
Both limits log a warning to stderr when triggered.

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
Parsing + DerivedCaches construction now runs entirely in a dedicated
OS thread inside open_path(). FileOpened handler only assigns the
pre-built caches, keeping the UI thread free during file load.
- Add build_derived_caches(): parallel hatch + mesh tessellation via rayon
- Extend Message::FileOpened / open_path return type with DerivedCaches
- Drop populate_*_from_document() calls from FileOpened handler
- Hatch pattern_scale multiplied by annotation_scale in model space so
pattern density stays consistent when CANNOSCALE changes
- Annotative check now uses AcAnnoPO xdata (R2007+ marker) instead of
relying solely on group-code-293 flag; falls back to is_annotative
for files with no xdata (old DXF backward compat)
- acadrust patched to local path for is_annotative field

- Scale popup dropdown replaces cycle behavior; paper-space viewport scale
editable when a viewport is active/selected
- CANNOSCALE persisted via DXF $USERR1 (read on open, write on save)
- PSLTSCALE: linetype dash lengths scaled by viewport anno_scale so dashes
appear uniform physical size in paper space
- MultiLeader: arrow size, dogleg length, and text height scale with
anno_scale; leader line paths (world coords) stay fixed
- Leader: arrow size and hookline length scale with anno_scale; also
corrects world_offset subtraction that was previously deferred to the
TruckObject::Lines path

Viewport-projected wires now clip at pixel level to their viewport boundary.
- WireModel.vp_scissor: Option<[f32; 4]> — paper-space bbox set on projection
- WireGpu.vp_scissor carries it through to the draw loop
- Pipeline.compute_wire_scissors() converts paper→NDC→pixel each frame
- render() calls set_scissor_rect() per wire, reset after viewport group
- INTEGRATION_GAPS.md: Viewport ⚠️ → ✅, all 51 gaps resolved

LwPolyline PLINEGEN=0 (DXF default): emit SegmentedLines with NaN
separators between vertex-to-vertex segments; wire_gpu resets
arc-length to 0 after each NaN so linetype pattern restarts per vertex.
PLINEGEN=1: existing Contour path unchanged (continuous pattern).
WireModel gains plinegen field propagated through tessellate pipeline.
Solid3D/Region/Body: call SabReader::read() when parse_sat() returns
None due to binary SAB format (DWG files / newer AutoCAD exports).

cxf.rs: missing non-ASCII glyphs now emit eprintln! once per font+char
pair via a global Mutex<HashSet> dedup set. ASCII chars silent (expected).
INTEGRATION_GAPS.md: ellipse partial arc snap marked done — endpoints are
correctly emitted via key_vertices → SnapType::Endpoint in snap engine.
Unicode warning gap closed. plinegen behaviour documented.

OLE2Frame: full TruckConvertible/Grippable/PropertyEditable/Transformable
impls in src/entities/ole2frame.rs — grips on corners + center, properties
panel, translate/scale transforms.
Shape: rotation (DXF code 50) now converted degrees→radians on load in
fix_dxf_dimension_rotations(), matching Dimension and Attribute behaviour.
All ❌ gaps resolved. Remaining: Viewport GPU scissor, LWPolyline plinegen.

Tessellates bottom + top paths with NaN-separated walls at each vertex.
Arc segments (bulge != 0) use 16-step parametric tessellation.

Arc: tessellates bottom + top arcs (32 segs each) with 2 endpoint walls.
Circle: tessellates bottom + top circles (64 segs each) with 4 quadrant walls.
Both use TruckObject::Lines with NaN-separated segments.

When line.thickness != 0, renders 4 NaN-separated wire segments
(bottom, top, left wall, right wall) using TruckObject::Lines.

Dimension measurement origin points (first_point, second_point,
definition_point, angle_vertex, etc.) are now emitted as Node snap
hints so OSNAP Node mode can locate them precisely without relying on
the tessellated geometry wire alone.

Hatch boundaries with arc or ellipse edges were silently dropped from
the wire outline, leaving gaps in the hatch contour. CircularArc and
EllipticArc boundary edges are now tessellated as polyline segments and
their centers are emitted as Center snap hints.

Entities carrying a non-standard extrusion normal (normal ≠ (0,0,1)) were
rendered flat in the XY plane. The DXF arbitrary-axis algorithm is now
implemented in scene::transform::{ocs_axes, ocs_point_to_wcs} and applied
during tessellation of Arc, Circle, and Line so they render correctly on
tilted planes in 3D DXF files.
