dotCooCoo fa89546397 PDF export: leave out an object whose opacity mask lost an image
An unclipped opacity mask is drawn on a white backdrop. When an image in
the mask art could not be written (a colorized image whose color channel
is over the size limit, an image that can't be decoded, or one placed
beyond the coordinates a file holds), the backdrop stayed white and the
masked object showed in full where the image should hide it.

The exporter now records an image left out while it writes mask art,
and leaves the masked object out instead of applying the incomplete
mask, with a warning. A failure in a nested mask makes the outer mask
incomplete too.

ham9zah e56aa356b5 Type on a path: joined scripts bend along the path so their joins stay connected
On a curved path each glyph was placed rigidly (turned to the tangent at
its middle), so its baseline ends stood off the curve and neighbours
turned by different angles: in scripts whose letters join, every join
opened into a notch. Measured with Arial on circles: at 29 pt on a
radius of 110 pt, 0.64 pt at the baseline and 1.24 pt at the height of
the joining stroke (a quarter of the size); 14.7 pt at 72 pt on a radius
of 60. Placing glyphs on the chord alone closes the baseline but leaves
about h (a_i + a_{i+1}) / 2R above it (0.71 pt here), so joined glyphs
are bent instead.

- Shaping marks each glyph of a segment whose script joins (Arabic,
  Syriac, N'Ko, Mongolian, Adlam and the other cursive scripts), by the
  segment's script, so a word bends as a whole.
- With the Rainbow effect such a glyph's outline is mapped point by
  point: pen space (x, y) -> P(s + x step/advance) + (y + rise) N there,
  each segment cut into pieces short enough for 0.01 pt (capped). A
  glyph the path doesn't turn under stays exactly as it was; Skew, 3D
  Ribbon, Stair Step and Gravity, vertical type, inline art and colour
  glyphs are unchanged. `PositionedGlyph::bend` records it; `xf` stays
  the straight glyph for the caret, hit testing and tools.
- PDF export draws bent glyphs as outlines and writes them again as
  invisible text where they stand, so they can be selected, searched
  and copied. SVG export outlines them (right-to-left type already was),
  never as a <textPath>, and labels the group with its text
  (role="img", aria-label) for screen readers and search.

Tests (crates/text/src/tests_path_joins.rs; installed Arabic font, skip
without one): the gap at the baseline and at join height is <= 0.01 pt
at 12, 29 and 72 pt on radii 60, 110 and 300, on both sides of the
path, with finite outlines; Latin on a curve and joined type on a
straight path are byte-for-byte what they were; the chord-only
prediction is checked.

vectorcraft-cli perf (load average 43 before, 34 after: not trustworthy;
the synthetic document has no type on a path, so bending doesn't run):
render fit 113.8 -> 132.7 ms, pan 115.5 -> 140.0 ms, 400% 32.9 -> 43.3
ms, hit test 1.36 -> 1.59 ms, save 81.5 -> 88.2 ms, open 306 -> 401 ms,
SVG 426 -> 439 ms, Pathfinder 93.7 -> 85.5 ms, handle drag 5.5 -> 6.7
ms, segment drag 5.1 -> 6.7 ms.

aiongg 714434527e Docking: panels on craft-ui's shared docking, floating panels in OS windows (#4135)
* Build: craft-libs at 2869b8cc

Pin craft-pdf, craft-print, craft-docpath, craft-ui, craft-keymap,
craft-window and the patched hayro/krilla backends to craft-libs
2869b8cc1077530bd07a7e192fb2b0e1304a1354, with the pdf-deps gate,
NOTICE, ASSETS.md and docs/pdf-backend.md at the same revision.

PDF: no modification date beyond the creation date, DeviceN images
are not JPEG-encoded, and clipping text draws nothing (its outlines
arrive as a clip path).

* Docking: compile against craft-ui at 2869b8cc

Floating windows are trees of groups: window_panels and window_active
read one as a flat group, and windows rebuilt from the legacy groups
keep their ids. Unknown dock actions are rejected, the new ones are
checked like the old, and every panel a close action removes keeps its
return location.

* Docking: panels and canvas on craft-ui's docking area

* Docking: tests for the dock area, flyouts, floating panels and the Tools panel

* Docking: catalogs without the old dock's strings

* Build: craft-libs at 8a503cfe

* Docking: floating panels in OS windows of their own on the desktop

* Docking: modal dialogs block panel windows; their keys and dropped files reach the main window

* Docking: art dragged onto a panel in its own window drops there

* Docking: module doc names the OS windows

* Build: craft-libs at a042cf26

* Docking: onto, above, below, collapsed, icon and column places on Float and Dock Panel; ui.docking

* Docking: command descriptions of Float, Dock, Move and Collapse Panel for the craft-ui layout

* Docking: control protocol describes the craft-ui layout, its commands and ui.docking

* Docking: rustfmt

* Docking: layouts saved before the canvas joined convert on load

Saved ui.json files and workspaces from before the shared layout held the
canvas (a dock-only tree plus floating_panels, docking_icons,
docking_collapsed, dock_collapsed and dock_width) convert into one layout:
the dock tree's groups in the main column, the icon column with the panels
dropped on it, floating groups and sets, sets docked as columns, collapsed
groups, the dock width and the places of closed panels. The legacy fields
are read, never written. A ui.json read only in part is copied to
ui.unreadable.json before anything saves over it.

* Docking: catalogs without the old collapse message

* Docking: converted floating sets start at most 720 points tall

* Docking: closed icon panels convert into the icon column; old floating rects, set heights and a copy of the file before conversion

* Build: craft-libs at 27e60765

* Docking: dock column places and icon count from the icon column; a docked column moves to a later place

* Build: craft-libs at d24e4bcc

* Build: craft-libs at 5bbe9f62

* Docs: floating panels in OS windows of their own close the other-monitor gap

* Docking: keys forwarded from a floating panel's OS window run shortcuts while the main window is unfocused

dotCooCoo bef464ea97 PDF export: the hyphen that ends a hyphenated line is written as text
With type written as text, PDF export drew the hyphen that ends a line
broken inside a word as a path. The file's text had no hyphen where the
canvas draws one, so copied or searched text read "considerations"
where the line shows "con-".

The hyphen is now written as text where the line draws it, as the
character the font gives its glyph to: "-", or U+2010 when the font
gives the glyph to U+2010 and not to "-". It is a text run of its own,
and right-to-left lines keep their /ReversedChars marking. The invisible
text of type without paint holds the hyphens too. Kashidas and list
markers are still drawn as paths.

Dylan M. TaylorandClaude Opus 5.5 1febfd1d31 Security: render and PDF export bounds for symbol expansion, dotted guides, blending groups and pinned images
CodeRabbit findings #32, #38, #41, #44, #102:

- A frame (and a PDF export) draws symbol instances holding at most 16M objects together
  (`vectorcraft_doc::MAX_SYMBOL_NODES`): nested instances multiplied past the depth limits.
- A dotted guide whose control polygon would make more than 100,000 dashes is drawn solid.
- Groups blending with their backdrop, drawn twice each, are drawn isolated past 4 nested.
- An image is decoded only while it and the images paints hold fit twice the decode allowance.

Taha-Mahmoodi 2bad646821 Gradients: a Perceptual gradient mixes its colours in OKLab, and SVG and PDF write it as an image
Illustrator 30.0's gradient Method, from the public documentation
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-perceptual-interpolation-in-gradients.html):
Classic or Perceptual; perceptual interpolation matches colour transitions to
how the eye perceives differences between colours, and perceptual gradients
are rasterised when saved as PDF or SVG.

- Gradient gains `method` (Classic | Perceptual; serde default Classic,
  written only when Perceptual, so older files open as Classic and Classic
  files are written as before). The colour crate's OKLab helpers open up for it.
- Perceptual mixes neighbouring stop colours in OKLab (sample, and
  sample_keep_model for the stroke meshes, Expand and blends); opacity stays
  linear. Renderers that mix linearly get stops on the perceptual curve,
  placed by halving each half segment where a straight line strays more than
  0.4 of a colour level (a nearly straight segment needs none). Classic
  gradients expand exactly as before.
- draws_as_pixels includes Perceptual gradients, so SVG and PDF write a
  Perceptual fill or stroke as an image at the document's raster effects
  resolution, clipped to what it paints. A gradient along or across a stroke
  stays slices (PDF no longer draws it as a within-stroke image).
- With Dither: a dithered Perceptual fill is the perceptual mix with dither's
  noise (the canvas's dithered grids are keyed by method too); SVG and PDF
  write it as an image with the noise, and a dithered Perceptual stroke as an
  image without it, as the canvas draws it (GradientPaint::pixels, SVG's
  raster_paint and PDF's area are told whether they paint a fill).

Taha-Mahmoodi 6b10b159b9 Gradients: dithered type in PDF keeps its resolution when scaled and stays searchable
Review follow-up (CodeRabbit): a gradient drawn as pixels was sized from its
area in the space it is drawn in, so type scaled 4 times got a quarter of the
raster effects resolution; the image is now sized from the area on the page,
within the same pixel caps. And type whose fill is drawn as art (a dithered
or freeform gradient's image, a pattern) went out as outlines only; its
characters are now also written as invisible text (rendering mode 3), as
unpainted type already is, so they can be selected and searched.

Taha-Mahmoodi cc1a660a6d Gradients: Dither in the Gradient panel draws a gradient fill with fine noise that hides banding
Illustrator 30.0's gradient Dither, from the public documentation
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-dither-in-gradients.html):
a Dither checkbox in the Gradient panel; dither converts the gradient into
pixels with subtle noise, works with gradient fills only, and follows the
Document Raster Effects resolution.

- Gradient gains `dither` (serde default false, written only when on, so
  older files open unchanged and new files keep it).
- The renderer draws a dithered linear or radial fill as an image paint: the
  gradient sampled a cell per device pixel or finer (quarter-octave steps,
  cached per thread), each channel given seeded triangular noise of up to a
  level before rounding. Same pixels every run; strokes and undithered fills
  draw exactly as before. PNG and other raster exports go through it.
- SVG and PDF write a dithered fill as an image at the document's raster
  effects resolution, clipped to the shape (the freeform-gradient path);
  characters' fills stay vector gradients in SVG, with a warning.
- paint.editGradient and paint.setFill take `dither`; strokes refuse it.
  The Gradient panel's Dither box is dimmed behind the Stroke proxy.
- i18n rows in all 24 catalogs; docs: G13, target-app-parity, ui-parity,

Taha-Mahmoodi a1d8952bc8 Gradients: a linear or radial gradient can be drawn as pixels, and SVG and PDF write such a gradient as an image
Shared groundwork for gradient options SVG and PDF can't express (Illustrator
30's dither and perceptual gradients): GradientPaint::pixels samples a placed
linear or radial gradient on a grid (Ramp: its stops, midpoints as stops, mixed
as the renderer mixes them), and draws_as_pixels says which gradients are drawn
that way (freeform ones, so far). The SVG and PDF writers' freeform-gradient
image path takes any such gradient, a linear or radial one at the document's
raster effects resolution. No change in output yet.

dotCooCoo 5f6c7b8da9 PDF export: a 16-bit PNG is written at 8 bits for PDF 1.3 and 1.4 instead of failing the export
When the Compression settings keep a PNG as it is, the PNG goes to
the PDF writer unchanged, and the writer refuses images of 16 bits a
sample below PDF 1.5. Saving a document with a placed 16-bit PNG as
PDF 1.4, or as a .ai file at 1.4, failed with "PDF writer error:
SixteenBitImage(...)" and wrote nothing. PDF 1.3 and PDF/X-3 failed
the same way for an opaque 16-bit PNG, and PDF/X-1a failed for a
16-bit gray PNG.

In PDF 1.3 and 1.4 files, such a PNG is now decoded and encoded again
at 8 bits a sample, with the same color type and ICC profile, before
the writer reads it. From PDF 1.5 on, it keeps its 16 bits. A 16-bit
PNG whose pixel data can't be decoded is left out with the note "an
image couldn't be decoded and is missing from the picture".

dotCooCoo 6807e757af PDF export: PDF and .ai files carry File Info's copyright status, notice and URL
The PDF writer's metadata has no copyright fields, so the XMP packet of
PDF exports and PDF-compatible .ai and .ait saves left out File Info's
copyright status, notice and URL. A PDF exported without its editing
data opened with the status Unknown and an empty notice and URL,
although the reader takes them from dc:rights, xmpRights:WebStatement
and xmpRights:Marked.

The export now adds those three properties to the XMP packet after
the writer has written it, as it does for the modification date.
Marked is True for Copyrighted and False for Public Domain, and is left
out for Unknown. The notice and URL are escaped for XML, and characters
XML 1.0 does not allow are left out. A document without a copyright
gets none of the properties.

Brian TorresandClaude Opus 5.5 ac7f0eebf8 PDF import and export: keep invisible text (rendering mode 3) as type (#2675)
Text drawn in rendering mode 3 (3 Tr), which is how a scanned page carries
its recognized OCR text, was left out on open (since #2988, with a warning),
so a scanned PDF opened and saved again lost its searchable text.

Import: an invisible glyph now comes in as type with neither fill nor
stroke. It skips the glyph-outline checks that guard how visible type looks,
and it joins only other invisible text on a line (Look::takes no longer
lets it into a stroke-only run). INVISIBLE_TEXT_NOTE now only reports text
that can't be type (text opened as outlines, Type 3 fonts), and
tests_reader_compat::invisible_text_is_reported_when_left_out expects the
invisible line as unpainted type when text opens as type.

Export and print: characters with no fill and no stroke are written as real
text inside a form marked Mark::Invisible; forms::finish sets that form's
text rendering mode to 3, so it draws nothing but stays selectable and
searchable (PDF/X-1a and PDF/A-2b too). The writer has no invisible mode of
its own, so this reuses the marked-form mechanism used for layers and
overprint.

Hamza 1c80b23745 Exports: SOURCE_DATE_EPOCH stands in for the clock, so output repeats
PNG, PDF, EPS, legacy `.ai`, packaged zips and saved `.vectorcraft` files
record the wall-clock time they were made in, so the same commands run twice
gave different bytes although the pixels matched (#2880):

  PDF   /CreationDate and /ModDate   D:20261018155816 vs D:20261018155817
  PNG   the `Creation Time` tEXt entry
  .vectorcraft  one byte of the stored date
  SVG   carries no time, and already repeated

`metadata::output_time` is the time a file records: `SOURCE_DATE_EPOCH` when it
holds a non-negative whole number of seconds, else the clock, as the
reproducible-builds specification defines it. A date a command is given
(`file.new {created}`, a save's `modified`) still wins over the variable, and a
blank, negative or non-numeric value is ignored so that an export is never
refused over the environment.

`metadata::now_unix` keeps the real clock and now has exactly two callers, both
of which must not be pinnable from the environment: the recovery heartbeat, and
the seed PDF encryption draws on.

dotCooCoo aa9cf83fd2 PDF export: PDF and .ai files keep the document's creation date
The engine built the PDF options without a creation date, so the
writer dated every PDF and PDF-compatible .ai file with the time it
was written. A document created on 2020-01-01 (File › File Info
shows the date) exported as a PDF with today's date in /CreationDate
and xmp:CreateDate. SVG export with the metadata option already
writes the document's own date.

The options now carry the document's File Info created date and the
time of writing as the modification date. A document without a
creation date is dated with the time of writing, as before, so PDF/X
files still get their required date. The PDF writer writes one date
for both, so the export then sets /ModDate, xmp:ModifyDate and the
PDF/A history dates to the time of writing; /CreationDate and
xmp:CreateDate keep the document's date. The page information mark
and the embedded editing data's modification date keep the time of
writing.

dotCooCoo df7daff3e4 PDF export: an image that can't be decoded is left out with a note instead of failing the export
When the PDF writer keeps a PNG, GIF or WebP image as it is, it accepts
the image once its header reads, and it reports pixel data that it
can't decode only when it finishes the file. An image whose pixel data
was cut short or damaged therefore failed the whole export with "PDF
writer error: Image(...)", and nothing was written. This happened in
Save as PDF, .ai saves, Save a Copy, Print, Export for Screens and
native files with PDF compatibility, and with On Copy: PDF turned on,
Copy left the PDF off the clipboard.

When the writer fails on an image's pixel data, the export now runs
again with that image left out. Its warnings hold the note that raster
exports give, once: "an image couldn't be decoded and is missing from
the picture". This note replaces the writer's "image '<key>' could not
be decoded and was skipped", which named the image by an internal key.
An export without such an image runs once, as before. A .ai file keeps
the image in its editing data and reopens with it.

japbcoelhoandClaude Opus 5.5 92a801a04f PDF: colours are written in the profiles assigned to the document
A document assigned a CMYK profile (Edit > Assign Profile) keeps it when
it is saved, but the working spaces are the app's, and a new session
starts with the defaults. Opened again, such a document exported its CMYK
colours tagged with the working CMYK space (VectorCraft Generic CMYK
(SWOP-like)) instead of its own profile, made that profile the PDF/X
output intent, and separated its RGB colours through it; print
separations did the same. edit.assignProfile still reported the assigned
profile, and document.exportPdf's documentation says CMYK colours are
tagged with "the document's CMYK profile".

Found on a book cover assigned FOGRA39L Coated: built in several
vectorcraft-cli runs, each reopening the saved document, its PDF/X-4
came out tagged with the SWOP-like profile unless every run set FOGRA39
as the working CMYK space again.

Export and print now work in the document's colour spaces: the active
settings with the assigned profiles in their place (document_cms). An
assigned profile that isn't available leaves the working space, with a
warning.

The MCP server read one line, ran it and answered it before reading the next,
so notifications/cancelled was never seen during a call and every request
(even ping) waited behind a running export.

- vectorcraft_doc::cancel: a thread-local cancel token and progress sink that
  long work polls. Checkpoints: PDF pages, PDF flattening, geometry bake,
  raster-effect flattening, drawing objects, raster artboards, and before any
  file is written. A cancelled command returns EngineError::Cancelled and
  changes nothing.
- Server::serve reads on its own thread: notifications/cancelled drops a
  queued request or stops the running one (no reply, as the MCP spec says),
  engine-free requests (ping, the list methods, prompts/get) are answered at
  once, a request that would wait behind a call running for 2 s is refused
  with -32003 naming that call, and _meta.progressToken gets
  notifications/progress (page n of m). Queue and output are bounded.
- The remote backend stops waiting for the app when the call is cancelled.

dotCooCoo f46b0f7dc4 PDF export: a page larger than 14,400 pt is written with a UserUnit
PDF export and .ai saves wrote every page in points. ISO 32000-1
(Annex C.2) gives 14,400 units as the longest page side, and a page
with a longer side got a media box past that limit. A PDF/A-2b file
with such a page failed veraPDF's page size rule (6.1.13).

Such a page now gets a UserUnit (PDF 1.6): its longer side divided by
14,400 and rounded up to the next thousandth, with the page's sizes
and coordinates in those units. A 20,000 × 10,000 pt artboard is
written as a 14,398.85 × 7,199.42 page with /UserUnit 1.389, and
VectorCraft's PDF import reads it back at 20,000 × 10,000 pt. Pages
up to 14,400 pt, PDF 1.3 to 1.5 files, PDF/X files and printing are
written as before.

A scatter brush whose art is an instance of a symbol stroked with that brush, or any brush whose
art is painted with a pattern whose tile is stroked with it, drew itself without end: a stack
overflow in a hand-written native file. Brush pieces already strip the brushes of their own
strokes; now what they draw by name that would draw a brushed stroke (a symbol instance, or a
pattern paint, also through the symbols and patterns those use) is left out too, in one place
(`stroke_pieces`, which every renderer and exporter calls with the document).

Probed the rest of item 2 of the depth follow-up with hand-written hostile inputs, kept as tests:
graph designs of deep art and of a symbol holding itself, Affinity groups nested to and past
both of its reader's caps, DXF blocks inserting themselves, EMF/WMF saving states without end,
and plug-in manifests and output nested 30,000 to 100,000 deep. None of them overflowed.

dotCooCoo d9bd9b134d Symbols: instances of imported symbols are measured by their art
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.

dotCooCoo 5d5e7a1dd2 PDF export: art beyond 1,000,000,000 pt is left out, so dev and test builds no longer abort
In builds with overflow checks (`cargo run`, `cargo test` and
`cargo xtask ci`), PDF export aborted the process when a number it
wrote rounded to -2,147,483,648 as an f32. pdf-writer 0.15 writes
-2,147,483,648.0 as an integer, and `Limits::register_int` overflows
when it takes the absolute value. krilla 0.8.2's `Surface` then fails
an assertion in its `Drop` while that panic unwinds.
`svg_hostile_markup_never_panics` in `import_fuzz` hit it with type
shifted 2,147,483,649 pt down. Paths, gradients, dash offsets, images
and artboards that far out hit it too, and so does a group around a
stroke wide enough to reach that far. Release builds have no overflow
checks.

PDF export now leaves out art whose coordinates or transform entries
lie beyond 1,000,000,000 in its own space or in the content stream it
is drawn into, and glyph lines whose spacing lies beyond 1,000,000,000
thousandths of an em. That covers paths and clipping paths, glyph
lines, images, gradients, strokes whose width, caps or miter spikes
reach that far, and the art and marks of a page whose artboard lies
that far, which is written blank. A dash offset beyond the bound is
written as its remainder after whole periods of the pattern.

The type's transform is now pushed inside the form that marks a fill
or stroke of type to overprint. The exporter checks what that form
holds through the type's transform, as it checks the same fill or
stroke without overprint.

bflatastic 934d83405c Part of #1286: constant alpha masks are drawn white, so the page shows where soft masks are read by luminosity
A CMYK page with transparency is drawn through an alpha soft mask that covers the page (a
non-isolated group). Its cover was black: opaque as alpha, but nothing shows in a reader that
takes the mask's luminosity. A white cover is the same mask either way.

arhammusheer 5beac4f122 #1244: smaller objects: Node 352 -> 152 bytes, NodeKind 200 -> 80, and a cheaper undo estimate
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).

bflatasticandClaude Opus 5.5 72c9cec0e0 Fix #847: draw Underline and Strikethrough
The styles were stored on the text and written to SVG's text-decoration,
but the type was drawn without the lines. vectorcraft_text::decorations
now gives each underlined or struck-through stretch of a run on a line
its bar, placed and sized from the font's own underline and strikeout
metrics (with fallbacks for fonts that have none). The canvas, Create
Outlines, PDF export (outlined and real text) and SVG's outlined text
draw them in the run's paint.

bflatasticandClaude Opus 5.5 00344f9b68 Fix #733: PDF export keeps type as text in embedded subset fonts
The PDF writer defaulted to Convert Text to Outlines, so every glyph of
every page became a path: a text-heavy PDF grew several times larger on
export (a 7-page document went from 27 KB to 226 KB) and its text could
no longer be selected or searched. Illustrator's PDF presets embed font
subsets and keep live text; that is now the default too
(advanced.outlineText: false). Outlining stays available as an option,
fonts that can't be embedded still become outlines with a warning, and
printer's marks (page information) are drawn as shapes as before.

haven b843fe8af3 M7: inline symbols in text
Document symbols placed inline in a run of type (beyond Illustrator; like
InDesign inline anchored objects): TextRun.inline holds the symbol, scale and
shift; the run is one U+FFFC laid out as a glyph sized to the art, centred on
the cap height. text.insertInline and Type > Insert Inline Symbol; editing
keeps the graphic whole; canvas, SVG (<use>) and PDF draw the art; Create
Outlines turns it into a symbol instance.

bflatasticandClaude Opus 5.5 50bb36ebc2 Part of #372: .ai files write layers and sublayers as PDF layers, hidden ones kept
A `.ai` file's PDF part is what apps that don't read VectorCraft's native
document open. It had no PDF layers: hidden layers and sublayers were left
out of it and everything else was flat page content.

- `.ai` files (Save As, exports, the CLI) write PDF layers unless
  `createLayers` is false (a PDF standard still decides for itself).
- createLayers writes sublayers too, as optional content groups listed
  under their layer's in `/Order`, hidden ones off with their art.
- A layer's form gets a box round the whole page instead of its art's
  bounds, which readers made a clipping group of, gathering a layer's art
  and its sublayers' in one group.
- PDF import: art inside a group, clip or form that dissolves into its
  parent keeps the layer it was drawn in, so sublayers nested in their
  layer's content import as sublayers.
- Save PDF: "Create PDF layers from layers and sublayers" (ja, es, it,
  pt-br, ru, zh-hans, zh-hant).

Hidden objects (not layers) still aren't in the PDF part.

bflatasticandClaude Opus 5.5 ab62b5f8e8 Fix #320: CMYK images stay CMYK from PDF import to PDF export
A PDF's DeviceCMYK image opened as RGB (the interpreter's pixels as a PNG),
so every export wrote it as DeviceRGB or ICC RGB, silently. Images now keep
their CMYK samples, as CMYK colours already did:

- Model: CMYK images are blobs holding CMYK samples, a four-component JPEG
  (Adobe's inverted samples) or a Deflate CMYK TIFF. vectorcraft-doc's cmyk
  module reads their ink amounts (ImageBlob::is_cmyk, ::cmyk, capped at 64
  megapixels) and writes the TIFF (ImageBlob::cmyk_tiff).
- PDF import: DeviceCMYK, CalCMYK and four-component ICC images keep their
  samples. A JPEG with Decode [1 0 1 0 1 0 1 0] is kept byte for byte; any
  other is decoded (8 or 16 bits, its Decode array applied) and stored as a
  CMYK TIFF. Masked CMYK images and 1/2/4-bit ones open in RGB with a warning.
  Placing a CMYK TIFF keeps it CMYK too.
- PDF export: CMYK images are written in CMYK (DeviceCMYK, or ICC-based with
  the CMYK profile when colours are tagged: PDF/X-3, PDF/X-4, PDF/A). A CMYK
  JPEG neither resampled nor recompressed passes through unchanged; others are
  resampled in CMYK and compressed as ZIP or as a CMYK JPEG (jpeg-encoder,
  which also replaces the ZIP fallback and its warning for images converted to
  CMYK). Output conversion treats them like CMYK colours: Preserve Numbers and
  PDF/X-1a keep their numbers, Convert to Destination converts them to another
  CMYK profile or to RGB through a 17^4 lookup table (cms::CmykLut, now also
  behind the renderer's ink table). A CMYK image that can't be decoded is
  reported in the warnings.
- Canvas: CMYK images show through the working CMYK profile, as CMYK fills
  do, and paint their own inks in ink planes (CMYK raster exports, CMYK
  blending). SVG export writes TIFF images as PNG.

Illustrator's Output › No Conversion keeps colour data as it is
(https://helpx.adobe.com/illustrator/using/pdf-options.html).

BFlatandClaude Opus 5.5 079f9a8b9a Fix #296: variable fonts list and draw every named style
The font database made one style per font file, so a variable font
such as Figtree[wght].ttf listed only its default instance (Light).
Faces now also yield their fvar named instances, each a style of the
family named by its subfamily name (the default instance is the face
itself; unnamed or duplicate instances are left out; axes and
instances read are capped). The system font scan reads the fvar table
beside the name table, so installed instances are listed before the
file is loaded and found by name and by PostScript name.

An instance face carries its axis settings: skrifa draws its outlines
and reads its metrics and advances at that location, harfrust shapes
with a ShaperInstance, so layout, the canvas, Create Outlines and hit
testing all use the instance. PDF export embeds it through krilla's
Font::new_variable, SVG @font-face through subsetter's
subset_with_variations: both write a static font of that instance.

Tests build a small variable font in code (test_fonts, via
write-fonts; no font file is committed) and check listing, resolving,
glyphs and advances, PDF and SVG export and damaged fvar/gvar tables;
Bahnschrift and Segoe UI Variable are checked where installed.

bflatasticandClaude Opus 5.5 04fa49413c M8.16: Envelopes bend images, symbols, gradients, patterns and appearance; warps keep their frame
- 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.
