dotCooCoo d5e1c00470 File formats: HEIC and HEIF images open and place
File › Open and File › Place read HEIC and HEIF still images (.heic,
.heif) through heic-rs 0.1.4, the pure-Rust decoder photocraft-heif
uses, and store the pixels as PNG. Single pictures and grids of tiles,
8 to 10 bits, with or without an alpha image, are read with the
container's rotation, mirror and crop applied. A grid without a color
box of its own takes its tiles'. When neither the image nor its tiles
have an nclx box, the HEVC stream's video signal type gives the
samples' matrix and range. An RGB ICC profile, or Display P3 with the
sRGB curve named by an nclx box or, without a color box, by the
stream, is converted to sRGB. The EXIF resolution tags size the image;
without them it is 72 ppi. When the container's rotations turn the
image an odd number of quarter turns, the resolution's axes swap with
the pixels'.

Image sequences, images that aren't HEVC-coded, grids of cropped tiles
and images past the pixel allowance are refused with a message before
the pixels are decoded. The allowance counts each coded picture at the
size its sequence parameter sets give it.

The decoder is in the engine's `heif` feature, which is on by default
and listed by the desktop, CLI and web apps. A build without it still
recognizes the files and refuses them with a message.

dotCooCoo 023ee90657 Perspective grid: Snap to Grid moves objects at every depth by one plane offset
With Snap to Grid on, a move of objects on one perspective plane at
different depths applied the snap correction only to the objects at the
first object's depth, and every other object moved by the pointer's
offset read at its own depth. Those objects left the grid and lost their
spacing.

Every object on the first object's plane now moves by that object's
plane offset plus the correction, so the edge of the joint bounds nearer
a gridline lands on it and the objects keep their spacing. A selection
at one depth snaps as before, and objects on other planes keep their own
offset.

dotCooCoo 6fce6d1884 Type: text.startList names the bullet each typed trigger starts
The command catalog said "* ", "# ", "> " and "+ " all start a list
with the filled dot. It now names the filled dot, hollow circle,
filled square and dash. The text.startList test checks each of the

dotCooCoo 246b8ed8cd Type: typed +, # and > start lists with a hollow circle, square and dash
Typed list detection gave every bulleted trigger the filled dot. Now
`*` and a space start a list with the filled dot (•), `+` with the
hollow circle (◦), `#` with the filled square (▪) and `>` with the dash
(–), each one of the existing Bullets presets. `1.`, `1)`, `A.` and `A)`
start the same numbered lists as before.

Only the list a typed trigger starts changes. Lists already in a
document keep their bullets, pasted triggers start no list, and Undo
and Redo of a typed list work as before.

dotCooCoo c1164f271f Type: Start Lists From Typed Markers turns typed list detection off
Preferences > Type gets Start Lists From Typed Markers (`typedLists`, on
by default). With it off, a list marker and a space typed with the Type
tool at the start of a paragraph (`1. `, `1) `, `A. `, `A) `, `* `,
`# `, `> `, `+ `) stay as text and start no list. `text.startList`,
`text.setFormat {list}` and the Bullets and Numbered List buttons work
as before.

The preference reaches the Type tool through `ToolContext::typed_lists`.
The label has a row in every catalog.

dotCooCoo 0d1a8b6ffa Actions: Batch Save and Close over data sets counts only saves that make the file the document's own
A recorded save in the template format writes a copy and leaves the
document's file as it was, so it no longer clears the warning or the
refusals. A recorded Save or Save As with its own path gives a never-saved,
converted or restored document its file before Save and Close, so the
batch runs and warns that every data set saves over that one file.

dotCooCoo 427029def6 Actions: Batch Save and Close over data sets follows a redirected Save step
With a destination folder and Override Save on, a recorded Save or Save As
step writes each data set to its own file in that folder and makes that
file the document's own, so Save and Close then saves each data set to its
own file. The batch no longer warns that every data set saves over one
file in that case, and no longer refuses a document that was never saved,
converted or restored, since the recorded step gives it a file first.

dotCooCoo 64cfa8b553 Actions: Batch over data sets warns about PDF, EPS, DXF and web exports and refuses Save and Close on converted documents
A recorded PDF, EPS, DXF, Save for Web or Save for Office Documents step
that gives a `path` writes the same file for every data set, because the
batch does not point these steps into the destination folder. The one-file
rule now counts them, so the dialog and `action.batch` warn.

Save and Close over the data sets of a document converted from an older
version or restored by Data Recovery is refused with "save the document
with Save As before Save and Close" before a data set is selected. Saving
such a document does not write its file, so the batch reported success
without saving anything. The message has a row in each of the 26 catalogs.

dotCooCoo 2ad0268388 Actions: Batch over data sets keeps Save and Close and warns when each data set saves over one file
Batch… with a Data Sets source offers None, Save and Close and Folder again.
Save and Close saves the open document over its own file after each data
set. When every data set saves over the same file, the dialog shows a
warning and `action.batch` returns `warning`: with Save and Close, or with
a recorded step that writes a file and that the batch does not point into
the destination folder. A Save step without a path counts when it writes
the document's own file; Save As, Save a Copy, Save as Template and Export
steps count when they give a path; Export for Screens counts when its
folder, given or from its preset, names a folder. Save and Close over the
data sets of a document that was never saved is refused with "the
document has never been saved" before a data set is selected.

dotCooCoo 7fd287238f Actions: Batch refuses Save and Close over data sets instead of saving each one over the open document
Data sets share one open document, so Save and Close saved every data set

returns an error for source datasets with destination saveAndClose before
it selects a data set or runs a step, and the Batch dialog offers None and
Folder for a Data Sets source, moving a Save and Close choice to Folder.

dotCooCoo 394bbb37c0 Effects: placed gradients move and scale with the Warp effects
A gradient placed with the Gradient tool stayed where it was when the
object's Warp effect changed the outline, so the warped shape no longer
matched its gradient.

Under each Warp style the placed gradients of a path now move and scale
from the path's bounds before the warp to its bounds after it, as they
do under Free Distort. This applies to an object's own Warp and to a
fill's or stroke's own (a stroke uses its stroke-inflated bounds), on
the canvas and in Object > Expand of the fill. In a group with a Warp
effect, each path's and compound path's gradient follows its own
bounds, and the own fills of the group and of the groups inside it
follow those groups' bounds. A warp with no bend and no distortion
leaves gradients exactly where they are, and gradients fitted to the
object are unchanged.

This changes how existing documents draw: a placed gradient on art with
a Warp effect now follows the warped outline instead of staying in
place.

How gradients follow the warp is VectorCraft's own rule. What the Warp
effects do to the object is described in
https://helpx.adobe.com/illustrator/using/reshaping-objects-effects.html

dotCooCoo 91d9639e6a Plug-ins: a permission grant covers only the module that was approved
A grant records the module's SHA-256, but only its permissions were
compared, so a module with other bytes under a granted id inherited the
grant when it listed no new permission.

A grant now covers a module only when the id, the SHA-256 and every
listed permission match. plugin.inspect reports needsApproval for a
changed module, plugin.install refuses it without a new grant and leaves
the installed module and its grant as they are, Install Plug-in and
File > Open ask again, and the plug-in store and plug-in folders skip it.
The same bytes install again without asking, and a module with no
permissions list or an empty one needs no grant. A grant whose hash is
not 64 lower-case hexadecimal digits covers nothing.

plugin.install still trusts the client that sends grant; the docs say so.

dotCooCoo 5522059417 Save: the save commands and Export for Screens refuse an unknown option key
document.save, file.saveAs, file.saveCopy and file.saveAsTemplate wrote
the file when given a key that no save format reads, beside the path or
in options, or an unknown key inside a PDF option object such as
marks.useDocumentBleed. document.exportForScreens did the same for an
unknown top-level key, a key in a format row and a key in the settings
of a format.

These commands now refuse such a key and name its path
(options.noSuchOption, formats[1].marks.useDocumentBleed). The svg
object is checked in every save, export and format row, also when the
file written is not SVG. A save still leaves out a key that only another
save format reads, and warns as before. A format row and a format's
settings still take includeArtboardFill and richBlack, which the
encoders read. document.exportPresets.save checks its settings, with the
rows and settings in it, the same way.

In the app, file.save and file.exportForScreens sent as commands are
checked as document.save and document.exportForScreens, and app.save is
checked before anything is written; MCP's app.save, file.save and
file.exportForScreens are checked the same way. The SVG Options dialog
no longer passes its internal fields on to the save.

HassanKhan 1e52ef587d Part of #4936: refuse malformed ids in text.spelling.check; dictionary-independent test; docs
- text.spelling.check checks a given `ids` as edit.findReplace does
  (checked_ids_param): a non-array, a negative, non-numeric or unknown id is
  an error instead of a check of the whole document. Null still means every
  visible, unlocked type object.
- The byte-offset test puts an em dash, not "café", before the unknown word,
  so it passes whichever dictionaries craft-proof is built with (CI builds
  with craft-i18n's, where "café" is unknown).
- Docs: the spell check engine in target-app-parity.md (Type advanced rows
  and evidence), gaps.md (G4), roadmap.md (M7) and the Language per
  character rows of type-parity.md, with status lines and revision history.

dotCooCoo a5ea32b386 Effects: fitted gradients turn with the Transform effect
A gradient fitted to the object refit to the outline after the object's
Transform effect rotated, reflected or scaled it unevenly, so the
gradient kept running left to right while the shape turned under it.
Object › Transform already turns such a gradient.

A Transform effect that a refit would not reproduce now fixes the
gradient to its fit on the geometry the effect takes, and then maps it
with that effect and the effects after it, as a placed gradient. Under
moves and even scales it draws as a refit does, and an effect that
scales the object to nothing across leaves it fitted. This applies to
an object's own effects, a fill's or stroke's own effects, and a
group's: in a group, the gradients fitted to its paths, to its own
fill, to the groups inside it and to its images' and symbol instances'
own fills each fix to the fit on their own object. Object › Expand of
the fill draws the same.

This changes how existing documents draw: art with a fitted gradient
and a Transform effect that rotates, reflects or scales it unevenly
now shows the gradient turned with the art. How gradients follow the
effect is VectorCraft's own rule.

way: a plug-in, shortcut set, script, preset, library or swatch library

dotCooCoo 76bb829e3a Graphs: a style that removes a mark's painted row resets the stored opacity
Applying or redefining a graphic style on a series mark whose fill or
stroke had paint, when the style leaves that row without paint, now
stores the row's opacity and blend mode on the graph. Before, the
opacity and blend mode another mark of the series left stayed, so a
Filled Lines band's outline kept a stroke opacity after a style without
a stroke went on a stroked marker. A row with no paint before and after
the edit still keeps what the graph stores.

dotCooCoo 517e0b7ae8 Effects: hiding a 3D effect still checks the values given with it
effect.setParams with visible: false skipped every 3D parameter check,
so a hidden edit could store a Classic depth of 2001, an unknown
surface or bevel, an empty light list or a Revolve edge other than left
or right. The values given are now checked by validate_three_d_params
(the checks of validate_three_d that do not build the art); after a
change of 3D type the values the effect keeps are checked too. The
object still does not need to fit while the effect is hidden.

dotCooCoo d8afed1562 Plug-ins: painted pieces keep their swatches in Pathfinder and baked art
Pathfinder effects, compound shapes, Expand Appearance and pattern
expansion now pass the document to the effects they evaluate, so a
painted piece that names a swatch or pattern takes part as drawn instead
of being refused. A path with a painted effect takes part in Pathfinder
and compound shapes as its pieces, each with its own paint, inside the
path's opacity and blend mode.

The renderer's kept effect art and live evaluations now count the
document's swatch and pattern names for objects with a plug-in effect,
so deleting or restoring a swatch a piece names redraws the object.

New from Template, Load Character/Paragraph/All Styles, Recolor's Other

The artboard of a document an importer opens is now kept within
±4,000,000 pt. Art at the edge (a zero-width path at x = 4,000,000, or a
stroke past the edge) gave an artboard beyond it, and every later edit
of the document was rejected.

HassanKhan 7a145576d4 Part of #4936: text.spelling.check lists unknown words, text.spelling.suggest suggests
The Edit > Spelling items have been placeholders with nothing behind them. This adds the
engine half of Check Spelling on craft-proof, the shared spelling engine in craft-libs (at the
revision the other craft-libs crates already pin), so no word list is copied here:

- text.spelling.check {ids?} lists the words the dictionaries don't know in every visible,
  unlocked type object (or ids), each run checked in its Character panel Language (English
  when it has none; nothing in a language without a dictionary), as {id, start, end, word,
  lang}. start/end are byte offsets in the object's text, the ones text.editRange takes, so a
  word is changed with text.editRange as one undo step. At most 10,000 words, with `more`.
- text.spelling.suggest {word, max?, lang?} gives the dictionary's suggestions, asked for one
  word at a time as craft-proof recommends.

English comes from the public-domain Moby word list built into craft-proof. Its dependencies
(log, miniz_oxide, toml, unicode-normalization) are already in the lockfile. The Check
Spelling dialog, Auto Spell Check and Edit Custom Dictionary follow in later PRs.

dotCooCoo 66a01584ae Plug-ins: inputs need a granted doc.read and stay within totals
A filter manifest that lists `inputs` must now list `doc.read` in
`permissions`, so installing it asks the user to grant them and the
Additional Plug-ins Folder loads it only once granted. Left out, the
manifest does not install.

The pixels of all images in one filter input take at most 16 MiB of
base64, and the runs and paragraphs of all its type at most 16 MiB of
JSON. An image whose pixels do not fit what is left comes with
`pixelsOmitted`, checked before it is decoded, and type that does not
fit comes with `truncated`. The read-only objects are kept once and
written into the input from there.

A field a filter adds to a read-only object is named in the refusal
with control and bidirectional characters escaped, cut to 64
characters.

dotCooCoo 68609fb43b Plug-ins: filters at API level 2 read type, images and symbol instances
A filter manifest at `api` 2 may list `inputs` (`type`, `image`,
`symbolInstance`). Such a filter is also given the selected objects of
those kinds, read only: type with its runs and paragraph attributes,
images with their pixel size, color mode and, when embedded and small
enough, their RGBA pixels in base64 (never a linked file's pixels or
path), and symbol instances with their symbol and transform.

The output must return each read-only object as {"id": ...} alone or
exactly as given. A change, an omission or a duplicate is refused
before the edit, so the document and undo history stay as they were,
including for output handed in from a heavy run. A filter without
`inputs` gets the same input bytes as before.

A manifest that lists `inputs` below `api` 2, outside a filter, with an
unknown or repeated kind, or with a permission list that lacks
`doc.read` does not install.

dotCooCoo b109378ae6 Plug-ins: live-effect plug-ins at API level 2 can paint the pieces they return
A live effect whose manifest has "api": 2 and "paintOutput": true returns
{"objects": [...]} as pieces, each drawn by itself in order with fills and
strokes of its own in the forms a filter returns. A piece without fills or
strokes keeps the ones the effect was given, and an empty list paints none.
An effect on a fill returns only fills, one on a stroke only strokes.

The whole result is checked before any of it is drawn: the output limits,
finite numbers in range with nothing clamped, known keys only, and every
swatch and pattern it names in the document. One fault draws that step of
the stack unchanged, keeps the effect record and puts the plug-in's name
and the field in plugin.info's lastError. Each piece counts against the
geometry-effect budget, so the painted effects of one stack make at most
100,000 pieces.

The pieces are drawn, measured and exported to PDF and SVG from the
appearance stack without changing the document, and Expand Appearance
writes them as ordinary paths in one undo step. The plug-in API level
rises to 2; plugin.list and plugin.info give api and paintOutput. Effects
without the key behave as before.

dotCooCoo fd94ebe86c Plug-ins: importer plug-ins open file types VectorCraft does not read
An importer plug-in (kind "importer", permission import.read) lists 1 to 8
file extensions and turns a file's bytes into objects, which open as a new
document whose artboard is their bounds. File › Open lists its extensions,
File › Open With (file.openWith) opens a file with a chosen importer, and
document.open takes importer and params. A built-in format that reads the
file by its content or extension always opens it; among importers listing
the same extension, the one whose id sorts first opens it. An importer reads
at most 128 MiB, and Place still reads only the built-in formats.

dotCooCoo 1ea4eefa80 Color: Generic CMYK separates nearby colors alike when an ink sits at 0 or 100%
The Generic CMYK solver clamps each ink to 0..1 after a step. When an
ink sits at 0 or 1 and the step pushes it further out, the clamp
removes most of the step, and the solve can stop after a step under
1e-6. Where it stopped depended on the input's last float bits. For hex
ed1e79, magenta ranged from 93.2% to 93.9% and yellow from 15.3% to
16.3% over 4,001 f32 values of its red, with 230 jumps over 0.001
between neighboring values.

An ink at 0 or 1 whose descent direction points out of the range now
stays where it is, and the step moves the other inks. The solve stops
when every ink is held. Two new tests step a channel one f32 at a time
and check that every ink stays within 0.001: the red of ed1e79 (cyan
held at 0) and the blue of sRGB (0, 0, 0.25) (cyan and magenta held at
1).

The solver still minimizes plain Lab distance to the gamut-mapped
target. The CMYK values of many RGB colors change; hex 00ff00 now
separates to C=61 M=0 Y=100 K=0 (cyan 0.6235 before, 0.6064 now), and
the swatch test that pins its name is updated.
