Grid snap (F9):
• snap spacing now tracks the visible grid zoom level — computed via
compute_grid_step() (same adaptive pow-of-5 logic as draw_grid),
updated on every ViewportMove so zooming in/out keeps snap aligned
with the grid lines on screen
Polar tracking (F10):
• configurable angle increment stored in polar_increment_deg (default 45°)
• right-click the POLAR pill to cycle through 15 → 30 → 45 → 90°
• pill label shows current angle ("POLAR 45°")
• visual guide line: while drawing with polar on, a dashed cyan line is
drawn from last_point along the snapped direction across the viewport
• SetPolarAngle message + handler; all polar_constrain() calls use the
stored increment instead of the hardcoded 45°
ROADMAP updated: Grid snap and Polar tracking marked ✅.

Both commands detect which terminal segment/vertex is nearest to the
pick point, compute the new endpoint along the segment direction, and
move only that terminal vertex — preserving all other vertices and bulge
values intact. ROADMAP updated: EXTEND and LENGTHEN marked ✅.

Add shared spline_ops module with:
- spline_to_bspline / bspline_to_spline: acadrust ↔ truck BSplineCurve conversion
- spline_sample_xy: sample DXF-XY projection at N+1 points with parameters
- spline_nearest_t: nearest-parameter search via coarse+bisection
- spline_pts_wire: world-space wire points for WireModel preview
TRIM: Spline entities can now be used as cutting boundaries (Geo::Spline
sampled into polyline segments) and as entities being trimmed; uses
BSplineCurve::cut() to produce surviving pieces.
EXTEND: extend_spline() shoots a tangent ray from the nearest endpoint
and appends a control point at the first boundary hit.
OFFSET: offset_spline() offsets each sample point along the local
perpendicular normal and rebuilds a new spline from the offset control pts.
BREAK: break_spline() uses spline_nearest_t() + BSplineCurve::cut() to
split the spline at one or two click points.
LENGTHEN: lengthen_spline() uses numerical arc-length integration +
bisection to cut the spline at the parameter corresponding to the new
requested length.

Replaced the simplified MOVE-based STRETCH with a real crossing-window
implementation. Workflow: pick two crossing-window corners, then base+target
points. Only vertices/endpoints inside the window are translated:
- Line: moves start/end independently
- LwPolyline/Polyline: moves individual vertices inside window
- Arc/Circle/Ellipse: moves whole entity if center is inside
- Insert/Text/MText: moves if insertion point is inside

Add HATCHEDIT (HE alias) command. Works on pre-selected hatch or via
entity pick. Accepts text options: P <pattern>, S <scale>, A <angle>.
Enter applies changes; rebuilds hatch entity and GPU model via add_hatch.

Add DDEDIT (ED alias) command that edits Text/MText/Attribute entities
in-place via the command line. Double-clicking a text entity in model space
now auto-launches DDEDIT for that entity. Supports Text, MText,
AttributeDefinition, and AttributeEntity types.

Extended FilletCommand and ChamferCommand to accept Lines and Arcs as
first/second entity. Added fillet_line_arc() and fillet_arc_arc()
geometry functions that find a tangent fillet circle between the two
entities, trim each to the tangent point, and insert the fillet arc.
r=0 case trims/extends to the nearest intersection without inserting an arc.

- Add explode_mline() that decomposes each MLine segment into its
spine Line plus two ±scale/2 offset Lines using per-vertex miter
directions, matching the visual representation of MLine entities
- Update file header to document all actually-supported entity types
(LwPolyline, Polyline2D/3D, Polyline, Insert, MLine)

Add lengthen_ellipse() that approximates the arc length via 128-point
numerical integration, then bisects to find the new angular span matching
the requested delta/total/percent, and adjusts the nearer endpoint.

Add offset_ellipse() that scales both semi-axes uniformly by the offset
distance (inside vs outside determined by projecting side_pt onto the
ellipse local frame). This is the standard CAD approximation; a true
offset of an ellipse is a higher-order Lamé curve.

Add break_ellipse() that projects the two break points onto the ellipse
parameter space (eccentric anomaly) and removes the CCW segment between
them, producing a partial Ellipse entity — matching AutoCAD break behaviour.

Previously wipeout solid fills were part of the hatch pass (pass 1),
drawn before wires (pass 5), so all wires appeared on top of the
wipeout. This fix moves wipeout fills into a dedicated pass 6 that
runs after wires, so the background-colored polygon correctly covers
the lines/text beneath it — matching AutoCAD behaviour.
- Scene.wipeout_models() separated from synced_hatch_models()
- Primitive.wipeout_hatches populated via wipeout_models()
- Pipeline.gpu_wipeouts + upload_wipeouts() + pass 6 after wires

Add VP freeze/thaw toggle columns to the layer panel when in a paper
space layout. Each viewport gets its own column (VP 1, VP 2, …) showing
a freeze icon per layer. Clicking toggles frozen_layers on the Viewport
entity and syncs back to the panel.
- scene: viewport_list() → [(handle, label, frozen_handles)]
- LayerPanel: VpCol + vp_frozen per layer, sync_with_viewports()
- Message::LayerToggleVpFreeze(layer_idx, vp_col_idx)
- Sync VP columns on layout switch, VPLAYER cmd, undo/redo, layer ops

Scene now carries bg_color / paper_bg_color fields (defaults match
previous hard-coded values). synced_hatch_models() reads these instead
of hard-coded constants, so Wipeout fills correctly use the custom
background when BACKGROUND <r> <g> <b> has been set.
BACKGROUND command syncs both DocumentTab.bg_color and scene.bg_color.

When add_entity receives a RasterImage without a definition_handle,
create an ImageDefinition object in document.objects and link it.
This ensures DWG/DXF files save the IMAGEDEF section correctly so
other CAD programs can resolve image paths on reload.

Replace raw text dump with proper boxed feature-control frame:
- parse_gdt_rows(): splits %%v cells and ^J row separators
- substitute_gdt_codes(): strips {\Fgdt;X} patterns, maps symbol chars
to 3-letter ASCII labels (POS, PRP, PAR, SYM, CIR, CYL, …)
- tessellate_tolerance(): outer rectangle, row separators, column
dividers, and CXF-tessellated cell text — all as Vec<Vec<[f32;2]>>
(TruckObject::Text polyline path)
- Column widths computed per cell content; text centred in each cell

Wipeout entities now render a background-colored solid fill polygon
(via the hatch GPU pipeline) that masks other hatch fills beneath them.
Fills use model space background (0.11 grey) or paper space background
(0.22/0.24/0.28). Polygon and rectangular clip boundaries both supported.
Selected wipeouts use a translucent blue highlight instead.

- Add `active_ucs: Option<Ucs>` per-tab state to DocumentTab
- Add `ucs_to_wcs`, `wcs_to_ucs`, `ucs_z_axis`, `ucs_rotated_z` helpers
- Add `Camera::pick_on_plane` for ray–plane intersection against any plane
- Mouse picks project onto the active UCS XY plane instead of world XY
- Typed coordinates are converted from UCS space to WCS before dispatch
- UCS command now really activates/deactivates a UCS:
- `UCS W` resets to WCS (clears active_ucs)
- `UCS <name>` activates a named UCS
- `UCS SAVE <name>` saves the current active UCS
- `UCS ORIGIN x,y,z` shifts origin (in current UCS space)
- `UCS X/Y/Z <angle>` rotates the UCS around its own axes

Before layout completes the viewport bounds are 0×0, causing project_point3
to produce NaN/Inf coordinates which panicked in lyon_path assertions.
Added early-return when bounds < 10px, and finite checks on all projected
and derived coordinates before calling any canvas drawing functions.

Screen-space UCS icon drawn on the existing selection canvas overlay.
Axes are projected from world space so the icon rotates with the camera,
always showing the correct X/Y/Z orientation relative to the drawing plane.
Each axis has its canonical color (X=red, Y=green, Z=blue) with arrowheads.
Icon visibility controlled by show_ucs_icon flag (default on); toggled by
UCSICON ON/OFF command which also updates paper-space viewport entities.

TruckConvertible renders the 4 perimeter edges as wireframe outline.
The scene injects a solid-fill HatchModel for the filled quad using the
existing hatch GPU pipeline (DXF Z-order: p0→p1→p3→p2).
Grippable provides 4 square corner grips; grip moves rebuild the fill model.
PropertyEditable exposes all 4 corners and thickness. Transformable handles
move/rotate/scale/mirror via the standard entity transform path.

Polyline, Line, CircularArc, EllipticArc, and Spline boundary edges
all get diamond grips at their control vertices. Dragging a grip updates
the underlying DXF boundary vertex and immediately rebuilds the GPU
hatch model via Scene::apply_grip.
