The Simplify help page says the slider starts at an auto-simplified value
(https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/modify-paths/manually-simplify-paths.html).
The slider opened at a fixed level 50 (1 pt), whatever the size of the
selection, so the first preview was the same tolerance for a 30 pt icon as
for a 1000 pt drawing.
The level Auto-Simplify picks for the selection is now one engine function,
vectorcraft_engine::auto_simplify_level (the existing 1/400-of-the-longer-
side rule in vectorcraft_pathops), which object.path.simplify {auto: true}
and the slider's opening fields both use. Object › Path › Simplify (and
ui.menuDialog, the Properties and contextual task bar buttons, which go
through the same menu dialog) opens the slider there, and the canvas
previews that result; Auto-Simplify still moves the slider back to it.
The retained Simplify dialog path is unchanged.
Verification: simplify_slider_opens_at_the_auto_simplify_level_of_the_selection
opens the slider on 1140, 285 and 28.5 pt waves (levels 35, 55, 89) and
checks the preview is exactly object.path.simplify {auto: true}'s result;
without the change it fails with level 50 != 35, and
simplify_opens_a_slider_whose_drag_previews_fewer_or_more_points fails with
{"level": 50} != {"level": 55}. cargo xtask ci: all 10 steps passed.
Illustrator documents Unite as a single compound path; use shape_node_styled and compoundPath.release in tests instead of wrapping islands in groups.

After Unite, split the result with draw2::components so each island (outer
contour plus its holes) becomes one group child instead of one compound path.

With paths selected but every offset empty (an inset larger than the
shape), Offset Path failed with "select paths", sending the user to
look for a selection problem. It now says the offset leaves nothing of
the selected paths; "select paths" stays for selections without paths.
Fixes#1590
The public Pathfinder documentation says Trim and Crop remove any
strokes, and Merge removes them and merges same-coloured fills. The
pieces kept every stroke, and Merge, grouping by the whole style, left
same-filled objects with different strokes apart. The three now drop
stroke layers before styles are compared.
Fixes#1570
Object > Path > Split Into Grid took a number of rows and columns and one gutter, and split each
selected path on its own. The dialog now has the documented options, the rows beside the columns:
number, height or width, gutter and total, with Add Guides and Preview. Several selected paths
become one grid over them all, painted as the topmost one, as documented.
object.path.splitIntoGrid takes rowGutter and columnGutter (gutter still sets both), totalHeight
and totalWidth, height and width (the size of each row and column, which sets the total) and
addGuides, which adds ruler guides along the row and column edges on the grid's layer.

Simplify and Add Anchor Points edited the document whenever the
selection held a path, so a call that changed no path still recorded
an undo step, emptied Redo, marked the document modified and turned
the selected live shapes into plain paths. OK in the Simplify dialog
did the same. Simplify at its default options leaves a rectangle, a
star, a line and a path with one anchor as they are, and Add Anchor
Points leaves a path with one anchor as it is.
Both commands go through edit_paths, which now computes the new paths
before it edits the document. When no path changes, the command
returns without editing the document, and the reply
({ids, before, after}) has the same form and counts as before. When
some paths change, the command replaces only those paths and records
one undo step, so a path that Simplify leaves as it is keeps its live
shape.
One line in the evidence list of docs/target-app-parity.md names the
commands.
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.
