The VPORT view direction fix and its test stay. The Export Strokes as
Centerlines option and the preset button are not in the documented DXF/DWG
export options, so they wait for the owner's decision.
Every symbol instance was measured as its transform applied to the
20 × 20 square around the origin, which symbols made in the app keep
their art in. The SVG and DXF importers keep symbol art as drawn, so
the box of an instance of an imported symbol did not match its art.
The SVG Star instance at x 20, y 30 draws from (20, 30) to (40, 50)
and was measured from (10, 20) to (30, 40). Align moved such an
instance by the wrong amount, clicks and marquees beside its art
selected it, and the canvas, exports and prints left it out when its
art reached the view or the page and the square did not.
An instance is now measured by its symbol's art, which
Document::symbol_boxes looks up in the document each time
(Node::geometric_bounds_with, visual_bounds_with and
reach_bounds_with). With Use Preview Bounds on, the strokes in the art
count at their own weight, as the canvas draws them, and
object.setBounds counts them at that weight when it sizes an instance
or an object that holds one. When strokes do not scale and a width or
height of 0 or more is smaller than what a path's stroke adds,
object.setBounds now gives the path no width or height, as it does
for an instance whose art has strokes; before, it mirrored the path.
With Use Preview Bounds on, object.setBounds now measures the margins
that strokes add object by object, the members of groups and the
objects in symbol instances' art included, and solves for the width,
height and reference point asked for when the width and height are 0
or more. Before, it measured the margins of the whole selection and
could miss the size or the reference point asked for when strokes did
not scale and the objects' strokes added different margins, and when
strokes scaled and the width and height were out of proportion, even
for one path. A clip group, a Shaper Group, a compound path, type, and
a group or instance with effects or an opacity mask of its own are each
measured as one object, and so is an instance in perspective or one
turned or slanted relative to the bounding box, other than by quarter
turns. When the selection holds more than 4,096 objects to measure this
way, each selected object is measured as one. Instances inside symbol
art are measured by their own symbol's art. An instance is measured as
the square when its symbol is missing, when its symbol or a symbol
nested in its art holds an instance of itself, and when symbols nest 32
deep in its art.
Align and Distribute, the Transform panel, the bounding box and the
selection outline, clicks, the marquee, document.inspect and
document.node, Fit to Artwork Bounds and Fit to Selected Art, canvas
culling, thumbnails, the SVG filter region of an instance with a
raster effect, raster effect images, Export Selection, the SVG of an
artboard, printing, and the PDF, EPS, EMF/WMF and DXF writers use the
new box. The renderer also culls an instance by the effects and
brushed strokes in its art, and it culls a blend, envelope or repeat
by the brush art of what it holds and the effects in the art of the
instances in it. It culls an instance with geometry effects of its own
by the effects in its art after those geometry effects reshape the art.
It measures the effects in a symbol's art once for each symbol and
linear part of the transform that places it. For symbols whose art
holds instances, it measures at most 4,096 placements a frame, and at
most 4,096 more for each pattern tile it rasterizes and each placed
document it draws. Past that, it estimates the reach from the symbol's
reach with no transform, which it measures once. When the drawn
document's symbols change, the renderer drops the cached bounds of the
instances and of the objects that hold them.
The PDF and EPS writers, the SVG of an artboard and Skip Blank
Artboards grow the box of an instance whose art holds brushed strokes
by 16 times the widest stroke (at least 1 pt) of the objects in that
art that have a brushed stroke, plus 8 pt, as the renderer grows the
cull bounds of a brushed path. They keep an instance whose brush art
reaches the page. The SVG of an artboard also keeps an object that
holds an instance when what the canvas paints for it, the effects in
the symbol's art and the instance's own included, reaches the artboard.
Not yet: other commands that measure objects, such as Select › All on
Active Artboard, Transform Each and Convert to Artboards, still measure
an instance by the square.
Docs: docs/mcp.md, docs/target-app-parity.md.
Rarely set fields move into one optional boxed NodeExtras, and large NodeKind payloads (images,
live shapes, blends, envelopes) are boxed. Every object, and every undo step that copies it,
shrinks: a 50k-path move keeps ~24.5 MB per step instead of ~40 MB. Files stay byte-identical
(Node keeps its flat JSON through a borrowed Serialize and a from-wire Deserialize, no flatten),
and loading is slightly faster. Undo and redo reuse their step's size estimate instead of
walking the document again (8.3 -> 5.6 ms for a 50k-path move).

A subpath that geometrically closes (e.g. an ellipse outline) was always emitted
with SPLINE group 70 = 8 (planar only). Autodesk's DXF reference defines bit 0
of group 70 as 'closed', and CAM software such as VCarve relies on it to treat
the cut as a pocket or profile rather than asking the operator to join endpoints.
Now `self.e.int(70, if sub.closed { 8 | 1 } else { 8 })`.
Test: extend lines_are_lwpolylines_curves_splines_and_fills_hatches to assert
the existing closed ellipse's SPLINE group 70 is '9' (1 closed + 8 planar).
Every edit of an object copied its whole appearance (its fills, strokes and effects, about
540 bytes for a basic object) into the new node, though a move leaves it as it is. Over 45
whole-selection moves of 10,000 paths, undo history grew by 589 MB; now 349 MB (41 % less), and
a nudge or a drag of the selection takes 12 ms instead of 15.
- Node::appearance is a vectorcraft_doc::Shared<Appearance>: copy-on-write. A clone shares it,
and the first change through DerefMut copies it (Arc::make_mut). Reads, writes, equality (also
against a plain Appearance) and the saved form are those of the Appearance itself, so call
sites read and change it as before. Sites that build or assign a whole appearance add .into(),
and the few that need a plain copy take (*n.appearance).clone().
- Node::transform changes the appearance only when it has gradients to transform, and pattern
paints are transformed only when there are some: a move no longer copies an appearance it
doesn't change.
The workspace suite (5,301 tests) and clippy pass with the change; the doc and engine suites
pass again after the transform guard.

$INSUNITS 22, 23 and 24 (US survey inch, yard and mile, as Autodesk's INSUNITS reference
lists them) had no size or name, so the drawing opened as unitless (millimetres, or inches
with $MEASUREMENT 0) and document.dxfInfo said Unitless.
They now derive from the US survey foot (1200/3937 m) like code 21, with their names.
The test reads each survey code's unit name and default scale and opens a survey-inch line at
7200.0144 pt.

Laser and cutter software skips HATCH entities, so shapes that were only
filled (type, traced art) reached it as nothing. Each filled area is now
written as its outlines (polylines and splines, in the fill's colour)
followed by the solid hatch; R12 keeps writing the outlines alone.

DXF text justified Fit now keeps its height and stretches or squeezes
horizontally to run exactly from its first point to its second; Aligned
text scales as a whole, height included, to do the same, its width factor
kept. Attributes justified the same way follow suit. Without a second point,
or with both points the same, the text keeps its size as before.
Root cause: the importer took the angle of the two points and anchored the
text at the first, but kept the text's height and width factor, ignoring the
distance between the points. The text now records that span and, when it
becomes a text object, is measured in the font it is set in, then given the
horizontal scale (Fit) or size (Aligned) that makes it end at the second
point, kept between 1% and 10,000% of its natural length. The import's
bounds estimate uses the same scale.

- Images distort as a raster mesh warp: cut by Fidelity into triangles,
each a clipped image under the affine map of its corners (pieces overlap
slightly, no seams; the renderer paints them without clip layers; SVG
writes the pixels once and <use>s them).
- Symbol instances distort as their symbol's art (the renderer's cache
follows edits to the symbol).
- Distort Appearance bakes strokes (filled outlines) and geometry effects
before bending; Distort Linear Gradients bends linear gradients; Distort
Pattern Fills bends the tiles. Opacity masks of the content bend too.
- Bug fix: a rotated, sheared or reflected warp envelope re-warped along
the page axes. Envelopes now keep their own frame (append-only model
field), so the warp turns with the art; move and scale keep it square.
- Live evaluation shares one set of hooks (vectorcraft_doc::live::Hooks,
vectorcraft_effects::{expand_live, expanded_live_group,
expand_live_deep}) between the canvas, Expand and every exporter.

Every exporter (SVG, PDF, EPS, EMF/WMF, DXF) evaluated live objects with no
text outliner, so type inside an envelope was written undistorted. They now
share vectorcraft_effects::expand_live_deep, which outlines type per run in
each run's paint, as the canvas now does too (it used the first run's paint
for the whole line).

A spline edge read an optional fit count (97) after its control
points. Files before DXF 2010 have no fit data there, so the 97 that
follows is the loop's count of source objects: the edge took it, then
failed reading fit points where the 330 handles are, and the whole
hatch was dropped without a warning. That is every associative hatch
bounded by a spline from AutoCAD R2000 to R2007.
A fit count is 0 or followed by fit points (11), and a source count
by handles (330), so the edge now only takes the 97 when it is 0 or
points follow.
Fixes#175.

ASCII DXF of any version opens (document.open) and places (file.place) through
a new reader in vectorcraft-cad: lines, LW/2D/3D polylines with bulge arcs,
circles, arcs, ellipses, NURBS splines (exact Beziers up to cubic, fitted
otherwise), solids, solid and pattern hatches, TEXT/MTEXT/ATTRIB as point
type, named blocks as symbols (one per look for by-block art), anonymous
blocks and dimensions as groups, MINSERT arrays, OCS extrusion; layers keep
off/frozen/locked/plot state; ACI and true colour, lineweights, linetypes and
transparency resolve through layers and blocks. The `dxf` option object picks
the layout, ratio or fit, lineweight scaling, centring and merged layers;
document.dxfInfo lists layouts, layers and units. Binary DXF and DWG answer a
clear error. The DXF Import Options dialog (dxfImport) asks on open and place
with a layout preview. Fuzzed in import_fuzz.

The Links panel lists every image (thumbnail, name, page, missing/modified/embedded
badge) with Show filters, sorting and thumbnail sizes; its buttons and flyout relink
(to a file or a folder), go to, update, edit the original, embed and unembed, show in
folder and open Placement Options. Link Info shows format, colour space, location, ppi
and effective ppi, dimensions, scale, rotation, size and dates. Edit > Edit Original
and the Properties panel's image section reach the same commands.
Engine: links.list, links.goTo, links.embed, links.unembed, links.info and
links.placementOptions; links.relink and links.update now place the new file as the
image's Placement Options say (transforms, bounds, file dimensions, fit, fill, the
alignment point, clip to the old bounds). Model: ImageObject.placement.
UI: links.editOriginal, links.reveal, ui.placementOptionsDialog; Services.open_file
