Root cause: the DXF reader never reads group code 340 (block_record
handle) inside LAYOUT objects, so layout.block_record stays Handle::NULL
after opening any DXF file. This caused current_layout_block_handle()
to return NULL, which made belongs_to_visible_block() return true for
every entity — all entities appeared in all layouts simultaneously.
Fix in current_layout_block_handle() — three-tier lookup:
1. Layout.block_record (non-null) — works for DWG files.
2. Conventional DXF name ("*Model_Space", "*Paper_Space", …) derived
from the layout's tab_order — works for standard DXF exporters.
3. Position-based fallback: sort paper-space block records and paper
layouts independently, then match by index — handles exporters that
set tab_order = 0 for all layouts.
Apply the same two-tier lookup to model_space_block_handle().

Paper limits:
- Change A4 fallback from 12×9 to 297×210 mm in paper_limits()
Context menu:
- Translate layout context menu labels to English (Rename / Delete)
Viewport clipping:
- Replace AABB-only culling with proper Cohen-Sutherland line clipping
in viewport_content_wires(); each projected segment is now clipped at
the exact viewport boundary instead of being included or discarded whole
- Add cs_clip() and clip_polyline_to_rect() free functions in scene/mod.rs
Frozen layers per-viewport UI:
- Inject a "Frozen Layers" EditText property in the Properties panel for
viewport entities (layer names resolved from handles at display time)
- Handle "frozen_layers" in PropGeomCommit: parse comma-separated names,
resolve to layer handles, update vp.frozen_layers in-place
PDF export improvements:
- Add offset_x/offset_y params to export_pdf() for model-space normalization:
coordinates are shifted so the drawing origin maps to the page origin
- Model space export computes extents via model_space_extents() (now public)
and adds a 5 % margin; falls back to A4 landscape for empty drawings
- Skip __paper_boundary__ wire in PDF (white background covers it)
- Map yellow (active viewport border) → black and cyan (vp border) → dark
blue for print-friendly output

- Add printpdf 0.9.1 dependency for native PDF generation.
- New src/io/pdf_export.rs: converts paper-space WireModels to a PDF
page (per-wire stroke color, line weight in Pt, NaN-split segments).
White/near-white colors are inverted to black for print output.
- Add PlotExport / PlotExportPath messages: opens a save-file dialog
and writes a .pdf next to the drawing file.
- Add PageSetupOpen/Close/WidthEdit/HeightEdit/Commit messages: a
centered modal panel lets the user enter paper width and height (mm);
on commit the Layout object's min/max_limits are updated in-place.
- Register PRINT / PLOT / EXPORT and PAGESETUP (PS) commands in
dispatch_command; fix MVIEW error message to English.
- Layout ribbon gains a "Plot" group with Page Setup and Export PDF
ribbon buttons.

- Add model_space_extents() to Scene: collects key_vertices from all
model-space entities to compute an AABB.
- Add auto_fit_viewport() to Scene: sets view_target to model centroid
and derives custom_scale / view_height so the content fits the new
viewport with a 10% margin.
- Call auto_fit_viewport() in commit_entity() after a viewport is added
to a paper-space layout, so newly placed viewports immediately show
model-space content at a sensible scale.
- Scale line_weight_px by the viewport scale factor when projecting
model-space wires into paper space, so dimension arrows and annotation
lines appear at the correct visual thickness.

- 3D view direction support: model geometry projected using view_right/
view_up vectors derived from Viewport.view_direction — enables Front,
Side, Isometric views inside paper-space viewports
- Proper AABB clipping: replaces centroid heuristic with bounding-box
intersection test against the exact viewport rectangle
- Per-viewport frozen layers: Viewport.frozen_layers Vec<Handle> is
resolved to layer handles and used to skip frozen entities
- view_target used consistently as the model-space pan origin
- Model wires collected per-viewport (inside the loop) so each viewport
can apply its own layer-freeze set

- Viewport ID uniqueness: commit_entity assigns max_existing_id+1
instead of always using id=2
- Lock/On boolean toggles in Properties panel (vp_locked, vp_on)
backed by status.locked / status.is_on fields
- Standard scale Choice picker: 1:500 to 10:1 (also syncs view_height)
- Numeric scale edit now syncs view_height when changed
- Standard view Choice picker: Top/Bottom/Front/Back/Left/Right/4×Iso
updates view_direction vector via apply_geom_prop
- Viewport content not rendered when status.is_on is false
- current_layout_block_handle_pub() added for external access

- Add active_viewport: Option<Handle> field to Scene
- Add EnterViewport(Handle) and ExitViewport messages
- Double-click on a user viewport (id > 1) enters MSPACE;
double-click on empty area while in MSPACE exits to PSPACE
- MSPACE middle-drag pans the viewport's model-space view (view_target)
- MSPACE scroll zooms the viewport's view_height / custom_scale
- Drawing commands inside MSPACE receive model-space coordinates
via paper_to_model() coordinate transform
- Active viewport rendered with yellow dashed border (vs. cyan solid)
- Camera screen_delta_to_world helper for MSPACE pan conversion
- LayoutSwitch clears active_viewport

- Kağıt sınırı dikdörtgeni: paper layout'ta Layout.min/max_limits'ten
beyaz çerçeve wire'ı oluşturulur, entity_wires()'a eklenir
- first_viewport_scale(): paper layout'taki ilk kullanıcı viewport'un ölçeğini döner
- paper_limits(): mevcut layout'un kağıt sınırlarını döner, sıfır boyutlu
layout için varsayılan 12×9 kullanılır
- Status bar scale göstergesi: hardcoded "1:1" yerine aktif viewport ölçeği
dinamik olarak "1:50", "2:1" vb. formatında gösterilir
- Overall viewport (ID=1) zaten gri renkte render ediliyor (tessellate_one)

- Layout sekme sağ-tıklamasında context menüsü (Yeniden Adlandır / Sil)
- Inline rename: sekme metin-giriş alanına dönüşür, Enter ile commit, ✕ ile iptal
- LayoutDelete: layout ve sahip olduğu tüm entity'leri kaldırır
- LayoutRename: Layout nesnesinin adını yerinde günceller
- LayoutCreate çakışma koruması: mevcut isimler arasında benzersiz ad bulur
- Escape tuşu açık rename/context menüsünü kapatır

- Deactivate ribbon tool highlight when command ends (issue #1)
- Reset last_point on new command dispatch to fix polar snap offset (issue #2)
- FILLET/CHAMFER: disable text input during entity pick so clicks reach viewport (issue #3)
- Dropdown icon buttons now use RibbonToolClick so they highlight blue when active
- FILLET/CHAMFER: AutoCAD-style sub-step UX — typing R/D + Enter prompts for value
- Fix FILLET arc preview plane: arc was rendering in XZ instead of XY
- Bump version to 0.1.1

Each command implementation is now in the same file as its ribbon
tool definition. Groups moved to a dedicated groups/ toolbar folder.

- ribbon.rs → ribbon/mod.rs + ribbon/widgets.rs
Extracted all rendering helpers, button styles, colour constants,
layout constants and dropdown position calculators into widgets.rs.
- scene/mod.rs → scene/mod.rs + scene/selection.rs + scene/render.rs
Moved SelectionState into selection.rs; moved CameraState, Primitive,
shader::Program/Primitive impls, render_style and resolve_pattern
into render.rs, reducing mod.rs from 1323 to ~1030 lines.
