Random in a Transform effect takes its seed from the object's id. When
art evaluated from an object repeats ids (the copies a Transform effect
makes, a copied group's members included, and the object under Crop
Marks), Expand Appearance and the baking in bake_document gave the
pieces new ids before expanding or baking their effects. The result
then drew with other random values than the canvas did: on main, 2,382
to 5,205 pixels of a 200 x 200 render changed after Expand Appearance,
and 7% to 14% after Flatten Transparency, for 50 pt squares with a
random Transform on their stroke, on their group or under Crop Marks.
bake_pieces now bakes each piece with the ids it has and gives new ids
after. expand_pieces expands the object's own pieces, and the other
members that repeat an id and hold a random Transform, before their
ids change. Expand Appearance now expands a node value
(expanded_node). The Crop Marks branch expands the object before the
object and the marks get new ids. The reply still lists the expanded
object first, then what was expanded inside it.
Object > Rasterize, Crop Image, Flatten Transparency, Expand
Appearance of raster effects and Vector Halftone draw the art with the
renderer and replace it with the result. When the art held an image
that could not be decoded, the renderer drew nothing for it, and the
result lacked the image with no message. A raster export of the same
art warns that "an image couldn't be decoded and is missing from the
picture".
These five commands now compare decode_failures before and after they
draw, as raster exports do, and their replies carry that text as
`warning`. They still make their result in one undo step. The app
shows a command's `warning` in the status bar: after a menu command,
after OK in a dialog with a preview, and after a tool runs a command
(Crop Image's Apply).

Raster Effects Settings, Vector halftone).
Type is drawn as its glyph outlines under a geometry effect, in EMF and
WMF export, in DXF export when it is written as outlines, through
Flatten Transparency with Convert All Text to Outlines, and inside an
envelope. Those outlines differed from the type the canvas draws in
four ways. They had no underline or strikethrough bars. A character
stroke on scaled type kept its unscaled weight. An unplaced gradient was
fitted to the glyphs it painted instead of the layout box. A run's
pattern tiles stayed in document space instead of scaling and turning
with the type. A group's or layer's own fills and strokes also painted
the glyphs of the type in it without the bars.
The outlines now include each run's underline and strikethrough bars,
as the canvas has drawn them since #850. Each run's path is made in
text space with its unplaced gradients fixed to the layout box, then
placed by the type's transform, which also scales its stroke weight
and dashes and transforms its pattern tiles. The type's own fills and
strokes have their unplaced gradients fixed to the bounding box of the
layout box in the document, where the canvas fits them.
Geometry effects that move or scale the outlines move and scale the
type's gradients with them: the type's own effects, also inside an
envelope and after Flatten Transparency has converted the type to
outlines, and the effects of a group, symbol instance or envelope that
holds the type. outline_text marks its group with a new node field,
type_outlines, which is saved with the document. reshape_leaves maps
the placed gradients in each marked group through the map that takes
the group's bounds before the effects onto its bounds after them. A
scale out of proportion stretches a radial gradient into an ellipse
and turns the isolines of a diagonal linear gradient, as it does on
type scaled by its own transform. Placed gradients outside those
groups stay where they are.
Offset Path, Outline Stroke, the Pathfinder panel, Clean Up, Make
Blend, Rasterize and the other commands that #1429's table marks 3,
except Split Into Grid, added, removed or replaced their objects one at
a time, and so did Remove Anchor Points, Redefine Symbol and the
removal of Shaper groups whose source art is gone. Each insertion or
removal moved the later objects of the layer or group. The lookups by
id that followed walked the tree, and every fourth walk rebuilt the
lookup cache. On 25,000 rectangles a release build of vectorcraft-cli
took 29.1 s for Offset Path.
These commands now make their edits with Document::wrap,
Document::insert_beside and Document::remove_many, in one pass over the
children of each layer or group, and Outline Stroke and Expand write
each new object into the place of the object it replaces. A list that
holds an object twice, or an object and another inside it, and that was
edited without an error before, is still edited one object at a time.
The documents, selections and undo steps are the same. On the same
rectangles Offset Path now takes 1.3 s.

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).

Same treatment as the branch's `as_chunks` commit (Rust 1.99's
`chunks_exact_to_as_chunks` lint) for the flattener's coverage pass, the
CMYK ink compositor, the Flattener Preview highlight and four test helpers.

object.flattenTransparency {preset?|options, ids?} splits the targets into groups of overlapping
objects. Groups with transparency become atomic regions (faces of the arrangement of every fill,
outlined stroke and clipping path) filled with the colour the renderer composites there: blend
modes, group opacity, isolated and non-isolated groups, knockout groups and knockout shapes, over
white or (Preserve Alpha) over nothing. Regions reached by gradients, patterns, images, opacity
masks or raster effects are rendered into one image per group, under the regions, clipped to
them with Clip Complex Regions. The raster/vector balance rasterizes whole groups past its region
budget (all at 0). Options and presets live in FlattenOptions; single visible paints keep their
colour and overprint; text and strokes can be outlined everywhere. One undo step.
