f515b556c7 feat: PRINT command — send layout to system printer via lp/lpr
The PRINT command renders the current layout to a temporary PDF (reusing
the existing PDF export pipeline) and dispatches it to the OS default
printer:
  - Linux/macOS: `lp` (CUPS) with `lpr` as fallback.
  - Windows: ShellExecute "print" verb (compiled-in, unused on Linux).

PLOT and EXPORT still open the save-file dialog as before.
Status messages are shown in the command line during the async job.

Closes ROADMAP 1.8.

ff39759d02 feat: VPORTS preset viewport configurations (2H / 2V / 4 / SINGLE)
VPORTS now accepts a layout subcommand in paper-space:
  VPORTS 2H     — two viewports side by side (horizontal split)
  VPORTS 2V     — two viewports stacked (vertical split)
  VPORTS 4      — 2×2 grid of four equal viewports
  VPORTS SINGLE — one full-page viewport

Paper dimensions are read from PlotSettings (fallback A4 landscape).
Existing user viewports are replaced and each new viewport is
auto-fitted to show model-space content.
Bare VPORTS still lists existing viewports.

Closes ROADMAP 8.5.

28f5c84b09 feat: Solid3D wire fallback render + Ole2Frame placeholder
- When SAT tessellation yields no mesh (binary SAB or unsupported ACIS
  geometry), render the pre-computed edge-wire polylines stored in
  Solid3D / Region / Body entities as a visible line fallback.
- Ole2Frame entities now render a bounding rectangle with diagonal X
  instead of an invisible stub — marks embedded OLE objects in the
  viewport.

Closes ROADMAP 2.13 (partial), 3.2 (Ole2Frame).

5cf7a19ca8 feat: Region and Body entity tessellation + render
Refactors solid3d_tess to share tessellate_sat() across Solid3D,
Region (2D planar ACIS body), and Body (3D ACIS body).
populate_meshes_from_document() and add_entity() now tessellate
all three entity types into GPU MeshModels when ACIS SAT data
is available.

Opens a reference panel listing all built-in keyboard shortcuts
(F3-F12, Ctrl+N/O/S/Z/C/X/V, etc.) and any user-defined overrides.

SHORTCUTS LIST         — open the panel
SHORTCUTS SET <k> <c>  — add/update a custom shortcut label
SHORTCUTS CLEAR <k>    — remove a custom entry

Custom shortcuts are stored in app state (runtime only) and shown
in the panel alongside the hardcoded bindings.

549ae38459 feat: BOX, SPHERE, CYLINDER primitives + EXTRUDE / REVOLVE commands
BOX, SPHERE, and CYLINDER build truck topology solids and tessellate
them into MeshModels stored alongside a Solid3D placeholder entity so
the GPU mesh pipeline renders them immediately.

EXTRUDE picks any closed 2D profile (Circle, LwPolyline, etc.),
attaches a planar face via try_attach_plane, and translational-sweeps
it (tsweep Face → Solid) along Z by the given height.

REVOLVE picks a profile, two axis points, and an angle (default 360°),
then rotational-sweeps the wire (rsweep) around the axis.

Three new CmdResult variants drive the operations:
  CommitSolid3D, ExtrudeEntity, RevolveEntity.

Scene::layer_color() added to retrieve the active layer's RGBA color.

a773a1a1f1 feat: REFEDIT / REFCLOSE — in-place block reference editing
REFEDIT picks an INSERT, extracts the block entities into model space
with the INSERT transform applied (translate + rotate + uniform scale),
and enters an editing session.  Any normal modify command works on the
temporary entities.

REFCLOSE SAVE applies the inverse transform, replaces the block
definition, and rebuilds all derived caches (hatch/image/mesh), so
every INSERT of that block reflects the edits immediately.
REFCLOSE DISCARD removes the temp entities without changing the block.

Non-uniform-scale inserts are rejected with an error message.
RefEditSession is stored on DocumentTab; undo snapshots bracket the
begin and close operations.

42048362e2 fix: MSAA resolve no longer overwrites widget backgrounds
MSAA and depth textures are now sized to the shader widget's clip
bounds instead of the full surface. The resolve writes to a matching
clip-sized intermediate texture; a blit pass (blit.wgsl, viewport
trick) then copies the result to the exact clip region of the surface
target, leaving all other widgets untouched.

c12b30ad3d feat: 4× MSAA anti-aliasing for main drawing pipelines
All main render pipelines (wire, hatch, image, mesh) now use 4×
multisampling. Drawing passes render to a dedicated MSAA color buffer;
a final empty resolve pass transfers the anti-aliased result to the
iced surface target. The ViewCube renders post-resolve at 1× to avoid
pipeline incompatibility. Depth buffer also upgraded to 4× MSAA.

f73d38f0a2 feat: Object Snap Tracking (OTRACK / F11)
- snap/mod.rs: Snapper gains otrack_enabled, tracking_points, dwell state;
  update_otrack_dwell() acquires a snap point after DWELL_THRESHOLD=4
  consecutive moves near the same position; otrack_snap() returns an
  H/V alignment snap position; clear_tracking() resets state on command end
- overlay.rs: selection_overlay accepts ost_points + cursor_screen;
  draws light-blue dashed H/V lines from acquired points + small cross marker
- statusbar.rs: OTRACK pill (F11) added next to DYN
- view.rs: projects tracking_points to screen, passes to selection_overlay
- update.rs: calls update_otrack_dwell + otrack_snap in ViewportMove;
  overrides effective point with OST alignment when no normal snap is active

4c1c13cab6 feat: Grid snap adaptive spacing + Polar tracking improvements
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 .

a99115bda5 feat: Solid3D (3DSOLID) ACIS tessellation
Parse SAT geometry directly into GPU MeshModel without going through

  • cone-surface faces   → parametric grid (handles cylinders and cones)
  • sphere-surface faces → UV sphere grid (GRID_U × GRID_V)
  • torus-surface faces  → UV torus grid

Scene integration:
  • add_entity(): tessellates Solid3D on insert, stores in scene.meshes
  • erase_entities(): removes mesh from scene.meshes on delete
  • populate_meshes_from_document(): rebuilds all meshes on file load
    and undo/redo (called alongside populate_hatches/images)

083eb5cbb5 feat: Spline support for TRIM, EXTEND, OFFSET, BREAK, and LENGTHEN
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.

b425c9e790 feat: LENGTHEN support for Ellipse entities
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.

eca4c96569 feat: OFFSET support for Ellipse entities
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.

519b305f0e feat: BREAK support for Ellipse entities
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.

09a6cc3521 feat: TRIM and EXTEND support for Ellipse entities
- Add Ellipse variant to the Geo boundary enum
- Implement algebraic line-ellipse intersection (le()) for fast boundary checks
- Add ellipse_seg_ts() using bisection for all boundary types including
  Arc/Circle/Ellipse boundaries (64-sample sign-change + 32-step bisection)
- Add trim_ellipse() producing partial Ellipse entities with updated parameters
- Add extend_ellipse() to stretch an ellipse arc to the nearest boundary
- Wire Ellipse into TrimCommand and ExtendCommand: on_entity_pick,
  on_entity_replaced, and on_hover_entity (live red/cyan preview)

80ca095121 feat: command history navigation with up/down arrow keys
CommandLine now records every submitted command in a recall list (up to
50 entries).  Pressing ↑ in the command input walks back through the
list, ↓ moves forward, and returning to the newest position restores
the draft text the user had typed before navigating.

0868a1719c feat: add RECTANG/REC and POLYGON/POL command aliases
Standard AutoCAD aliases now dispatch to the existing RECT and POLY
commands respectively, so users familiar with AutoCAD naming find
them without modification.
