PageSetup panel:
- Paper size presets (A4/A3/A2/A1/A0 portrait+landscape, Letter)
- Plot area selector: Layout vs Extents
- Center-on-page toggle
- Plot offset X/Y fields
- Rotation picker: 0° / 90° / 180° / 270°
PlotSettings (acadrust object):
- PageSetupCommit finds or creates a PlotSettings object in the document
- Writes paper size, plot type, centering, offset, rotation to it
- DXF round-trip: PlotSettings persisted to file
PDF export:
- Reads PlotSettings for the active layout
- Applies centering (auto-computes offset from wire extents)
- Applies offset X/Y from PlotSettings
- Applies rotation via PDF CTM transformation matrix
- Swaps paper dimensions for 90°/270° rotation

Snap is now suppressed (both cursor indicator and coordinate snapping)
when a command is in entity-pick mode (needs_entity_pick) or
selection-gathering mode (is_selection_gathering), and restored
automatically when the mode ends.

Selection, snapping and editing are now mode-aware:
PSPACE (paper layout, no active viewport)
- Only paper-space entities (viewport borders, title blocks, etc.) are
hit-testable and selectable. Viewport content wires are invisible to
the interaction layer.
- Drawing commands add entities to the paper-space layout block so
annotations/title blocks land on the sheet, not in model space.
MSPACE (active viewport entered)
- Only model-space entities visible through the active viewport are
hit-testable. Other viewports' content and paper entities are ignored.
- Drawing commands add entities to model space (correct DXF block).
- Snap results from projected viewport-content wires are converted from
paper-space back to model-space via paper_to_model so that placed
coordinates and command previews are consistent.
Entering/exiting MSPACE clears the current selection so no stale
cross-space selection is carried over.
Implementation:
- Scene::hit_test_wires() returns mode-filtered wires for all
hit-tests, snaps, and selections (entity_wires() still returns
everything for rendering and PDF export).
- viewport_content_wires() gains an Option<Handle> filter to render
only the active viewport's content for MSPACE hit-testing.
- Scene::add_entity() routes to the paper-layout block or model-space
block depending on current_layout / active_viewport.

Four bugs prevented viewports from working like AutoCAD model-space windows:
1. Dead-code double-click block: `!is_down2` was always false because
`is_down2 = sel.left_down` is captured while the button is still held
(before the selection block clears it). Changed to `is_down` so the
double-click handler actually fires.
2. Inverted pan direction: pan_active_viewport used `-=` on the delta
returned by screen_delta_to_world, which is the same delta that cam.pan
*adds* to its target — causing reversed drag. Changed to `+=`.
3. Zoom not cursor-centered: zoom_active_viewport now accepts an optional
paper-space cursor position and adjusts view_target so the model point
under the cursor stays fixed (same as cam.zoom_about_point).
4. ESC did not exit MSPACE: CommandEscape now calls ExitViewport when
active_viewport is set and no command is running.
Also added MS/MSPACE and PSPACE command aliases, and MspaceCommand /
PspaceCommand messages so MS auto-enters the first viewport.

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.

- 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
