Three changes to make paper-space viewports render correctly on
UTM-scale drawings whose viewports were saved with default
view_target=(0, 0, 0) and a view_center pointing at empty WCS:
1. **Auto-fit fallback.** When the saved view's WCS rect doesn't
overlap the IQR-bounded content cluster (`world_offset ±
local_extent_max`), override `view_center` with `world_offset` and
recompute `view_height` to fit the cluster into the paper viewport.
Matches AutoCAD's silent auto-fit-on-open for stale / uninitialized
viewports; without it those viewports rendered blank.
2. **f64 projection inner loop.** The previous f32 path computed
`(wire_offset_rel - target_offset_rel).dot(view_right) -
view_center` by subtracting values at ~5e6 magnitude (f32 ULP
~0.5 m) to land on a small paper offset. The cancellation produced
centimetre-scale jitter on paper output even when the model was
clean. Reconstruct the wire WCS coord, subtract the display center,
and dot-project in f64; cast to f32 only at the final paper
position where magnitudes are bounded by the viewport rect.
3. **examples/inspect_viewports.rs** — diagnostic that dumps every
viewport's saved view fields (view_target, view_center, view_height
vs paper height, custom_scale, status flags) plus drawing-level
insertion_units and model-space extents. Used to verify that
acadrust's DWG reader reads view_height correctly; the
`view_height == vp.height` patterns observed on real files turn out
to be genuine "default 1:1" file content rather than a reader bug
(a round-trip test through DwgWriter / DwgReader survives all
per-viewport values).
Also: switch the `acadrust` patch from `HakanSeven12/acadrust@feat/
expose-blockrecord-is-loaded` (a stale branch with the abandoned
is_loaded experiment) to `hakanaktt/acadrust@main`. Upstream main
now carries the layout paper-dimensions and mirrored-arc fixes that
this branch used to add — plus PR #20's DXF reading fixes that the
old branch was missing.

When the host DWG marks an xref as Unloaded (via XREF→Unload in
AutoCAD), the user explicitly chose NOT to load that reference. We
were ignoring that and pulling the external file in anyway, which
on large drawings could push GPU memory past the device budget.
Bump the acadrust dep to the branch that exposes
`BlockRecord::is_loaded`, then short-circuit `resolve_xrefs` for
any entry with `is_loaded == Some(false)`. New `XrefStatus::Unloaded`
surfaces this in the command-line log so the user can see which
references were skipped (and can re-load them via the XREF dialog).

Old fork was deleted and re-forked from upstream; the mirror-handedness fix
is now isolated on fix/mirrored-arc-handedness with no other diverging work.
Mirrored INSERTs reverse OCS handedness, but acadrust's explode used to
keep the original normal — making CCW-around-normal arcs and ellipses
sweep the wrong way. The fix lives in acadrust 7c711e9, which flips the
new normal when det < 0 and reprojects center/major_axis/angles into the
new OCS. H7CAD's fix_mirrored_arc workaround is no longer needed.
- 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

paper_limits() now reads paper_width/paper_height/plot_rotation from the
Layout object (populated by a patched acadrust from the embedded DWG
PlotSettings). This fixes layouts where min/max_limits do not match the
physical paper size (e.g. A4 portrait content inside A3 landscape limits).
DXF files use codes 44/45/73 from raw_plot_settings_codes; DWG files use
the PlotSettings block embedded in the LAYOUT object. Both fall back to
min/max_limits when paper_width is zero.
Depends on HakanSeven12/acadrust feat/layout-paper-dimensions (PR #21 on
hakanaktt/acadrust); using that fork until the PR is merged.

Extract tessellate_one body into a Send-compatible free function
tessellate_entity, then drive it with rayon::into_par_iter() in
wires_for_block(). Spreads file-open and post-edit tessellation across
all CPU cores. Navigation frames are unaffected (Options A/B cache
eliminates per-frame tessellation entirely).

Block-definition geometry (entities stored inside named blocks) was
leaking into the viewport when DXF files omit the owner-handle group
code (330) on block-content entities.
The fix tightens `belongs_to_visible_block`: when `owner_handle` is
null, the current layout block-record's `entity_handles` list is used
as the authoritative allow-list before falling back to the older
"not-in-any-other-block" heuristic. This ensures block definitions
are never rendered directly, only when referenced via an INSERT.
Bumps version to 0.1.4.

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.

- 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.
