From the review of #5228. The finished CMYK group was drawn through
whatever paint transform a preceding shading pattern left on the
context, so its cyan half showed magenta. Hayro patch (27) now resets
the paint transform before drawing the group's pixels.
Two regression tests, both reported in that review:
- a pattern painted before the group (fails without the reset);
- the Color blend mode over an empty CMYK group, swept over all 256 K
levels (failed on nine levels before #5199's vello_cpu fix was merged
in; passes with it).

main's knockout patch (hayro (22)) draws each element of a knockout group
once in erase mode, to clear what the group drew under the element's shape.
An isolated DeviceCMYK group nested in such an element still took the CMYK
path in that pass, and drew its finished pixels with Normal blending over
what should have been cleared. draw_isolated_cmyk_group now declines while
erasing, so the group's contents are interpreted in erase mode as before.
The new test fails without the fix (the centre shows red through the
magenta: [240, 63, 168] against [245, 127, 197] for the DeviceRGB control).

main has taken hayro-interpret patches up to (66) and hayro up to (25)
since #3777 was opened, and open PRs claim hayro-interpret (67)-(69) and
hayro (26). The isolated DeviceCMYK group patches become hayro-interpret
(70) and hayro (27). vendor/README.md names the tests by their new path,
raster::tests::isolated_cmyk_groups.

Review of #3777 (test report by mtlcl410).
- A group wider than about 512 device pixels lost its blend mode in the
tiles that a paint covers completely: on the bare pass canvas, vello_cpu
fills such a tile without the blend mode. At 300 dpi, magenta then black
with Difference drew black in the middle of the group, not green. Each
ink pass now draws inside a layer of its own.
- A nested isolated group that names another blending space (for example
/CS /DeviceRGB) blends in that space (ISO 32000-2 §11.3.4). The
interpreter now tells the device about such a group
(Device::group_blends_outside_device_cmyk), and a pass that meets one
declines, so the enclosing group is drawn as before. A non-isolated
group's /CS is ignored (ISO 32000-2 §11.6.6, Table 145, CS: it takes its parent's space), so
it stays in the enclosing group's CMYK.
Test: raster::tests::isolated_cmyk_groups_blend_at_any_size_and_respect_nested_spaces.

Review of #3777. `Color::ink_tints` no longer gives tints for a
four-component ICCBased colour. Such a colour keeps its own profile, so a
group that holds one is drawn as before. vendor/README.md: the hayro
patch (21) entry refers to hayro-interpret patch (45), not (44).
ISO 32000-2 §11.3.4: the elements of a transparency group blend in the
group's colour space. For a subtractive space, each component is
complemented before the blend function and again after it. §11.3.5.3:
the nonseparable modes blend C, M and Y as their complements R, G and B,
and K comes from the backdrop (Hue, Saturation, Color) or from the source
(Luminosity). PdfCraft converted each colour to RGB and blended in RGB.
A print test file's blend-mode patch then showed an X in almost every
cell: magenta under black with Difference stayed magenta, not green.
hayro-interpret patch (45): CmykGroup and Device::draw_isolated_cmyk_group
(default false) for isolated, non-knockout groups with /CS /DeviceCMYK.
interpret_form_contents is now a function of its own. Color::ink_tints
and color::cmyk_to_srgb8 are new.
hayro patch (21): the renderer draws such a group as a CMY pass and a K
pass of complemented tints. It converts the tints to RGB with the CMYK
profile and composites the result through the group's layer. The group
is drawn as before with reading colours, for contents without process
tints (RGB, spot colours, patterns, images) and above 2^24 pixels.
Test: raster::tests::isolated_groups_blend_in_device_cmyk.

* M5: Import comments takes another PDF and copies its comments onto the same pages
Import comments read only XFDF, FDF, XML, XDP, CSV and text data files.
It now also takes a PDF: each comment of that PDF is copied onto the
page with the same number, at the same place, with its appearance
stream, its pop-up, its replies and its layer. Comments on pages past
the document's last page are left out, together with replies to them.
Links, form fields and redaction marks are not copied. A comment named
like one already on its page replaces it, as an XFDF or FDF import
does. A PDF without comments is refused with "nothing in the file
matches this document", and a PDF that needs a password is refused.
- organize: import_comments copies the comments with the page copier
that Insert Pages uses, and registers the layers they use.
- engine: Edit::ImportData reads a file that starts with %PDF- as a PDF.
Any other file goes to the data importer first, and is read as a PDF
when that fails, %PDF- occurs in its first 1,024 bytes and the PDF
reader opens it.
- ui: Comments > Import comments lists .pdf files; form.import_data
lists the same files as before.
- automation: the doc_import_data description names the PDF case.
- parity: comment.import-from-pdf is shipped.
* Import comments: an annotation that is no comment keeps its name
A comment imported from a PDF replaced any annotation of the same /NM
on its page that was not locked, a redaction mark or a widget, so a
link, screen or 3D annotation of that name was overwritten. Only an
annotation whose subtype is one of the copied comment subtypes is
replaced now; for any other, the copy is added beside it without the
name. The subtype is read through an indirect reference.
* Import comments: index each page's annotations instead of scanning them per comment
* Import comments: a layer that BaseState OFF hides stays hidden
* Import comments: a PDF with binary bytes before its header imports on an XFA form, and two comments with one name both land
On an XFA form, a decode failure no longer stops the import when a PDF
header is in the first 1,024 bytes; the PDF's comments are copied. Two
incoming comments on one page with the same /NM no longer replace the
same comment: the first replaces it, and the second is added without
the name.
* Import comments: an inline annotation on the page is replaced by name
An annotation written inline in a page's /Annots is made an indirect
object before names are matched, so an incoming comment with its /NM
replaces it instead of being added beside it.
* Import comments: two new comments with one name keep it once
When no comment on the page has the name, the first incoming comment
keeps its /NM and each later one with the same name is added without it.
* M6: Organize pages ▸ Page properties sets the selected pages' tab order
Page properties in the Organize pages panel was listed as planned. In
the app, a page's tab order could only be set for every page at once,
with the form.tab_order commands, which offer no Unspecified. (The
form_tab_order tool already set chosen pages, Unspecified included.)
- Page properties (page.properties) opens a Tab Order dialog for the
selected pages, with Use Row Order, Use Column Order, Use Document
Structure and Unspecified. OK writes Edit::SetTabOrder for those pages
as one undo step. The dialog opens on the pages' order, or with no
choice made when they differ, and then OK is off until one is chosen.
OK on the order the pages already have adds no undo step.
- Rows and columns run right to left in a document bound on the right,
as Use Row Order and Use Column Order are described. PdfCraft reads a
right-to-left binding from /ViewerPreferences /Direction /R2L
(ISO 32000-1, 12.2, Table 150). Before, rank_tabs ranked them left to
right.
- A page whose /Tabs is an indirect object now takes its row, column or
structure order. Before, rank_tabs read only a direct name and ranked
the page in annotation order.
- pdfcraft_forms::tab_orders and Document::tab_orders read each page's
/Tabs. form_tab_order returns them as page_tabs, and reads without
changing anything when it is given no order or field.
- set_option("dialog", "page-properties") opens the dialog.
- Parity: organize.page-tab-order is shipped, and its notes say the
Actions tab of Page Properties (organize.page-actions) is still
planned; the Organize pages grid notes list Page properties.
* Page properties: OK applies only to the document the dialog was opened on
The draft keeps the document's id. When another document is active by
OK, the dialog closes without changing either document.
* Menus: list Page properties… in the Pages menu
The menu bar now lists its commands explicitly, and every command with a menu group must appear in it.
* Page properties: apply the tab order only to an unchanged document
An edit, undo or redo made while the dialog is open can move the pages
at the stored indices. OK now closes the dialog without changing a page
when the document's edit generation differs from when it opened.
* Page properties: say when a document change cancels the tab order
OK shows a notice when the document changed or another document became
active while the dialog was open, so the user knows to open it again.
* M6: form script messages keep their title, icon and buttons, and every one is shown (#4293, #4294)
* M6: a form script message waits for a notice the toast already shows
* M6: form script messages past the queue's room are counted and reported
* M6: a sentence break in the merged parity note
* M6: an object that names no parameter is a message's text, as a String object or a caught error
* M6: the count of left-out script messages is said again if another notice replaces it before its time
* M6: a full stop between two sentences of the FormCalc parity note
* chore: re-run CI (a frame-budget timing test missed on a shared runner)
Export Data (CSV) wrote field names and values as they are, so a value
from a received form that starts with = or @ (or + or - when it is not a
number) runs as a formula when the CSV is opened in a spreadsheet.
It now uses the rule merge_csv got in #4101, moved unchanged into
runs_as_formula, so the merge report's output is the same. Import Data
takes the added ' off again, so Export Data then Import Data gives back
every value unchanged.
The script already validated CARGO_BUILD_TARGET and named the archive after the arch, but
cargo build ignored it, so a cross build compiled for the host. Pass --target, resolve
host-tuple to the build host's triple first, and skip the --version smoke run for any
CARGO_BUILD_TARGET build (an aarch64 binary cannot run on the x86_64 VM).
The previous commit's message and this header said the Luminosity ramp
passes because pages use the u8 pipeline. That wasn't established; the
case simply renders correctly here, so the test is a guard.

vello_cpu 0.0.8's clip_color, shared by the nonseparable blend modes,
divided 0 by 0 when a gray's equal components were rounded just below 0
or above 1 after set_lum. The NaN drew the pixel black at the source's
alpha whatever the backdrop: nine gray levels under /BM /Color in an
empty isolated group (0.96 g among them) rendered (0, 0, 0), and two
more at half opacity came out wrong.
Vendor vello_cpu 0.0.8 (Apache-2.0 OR MIT) with a backport of
linebender/vello#2000, which clips only when the denominator is
positive. No vello_cpu release carries the fix yet; drop the copy when
one does.
Tests in it::nonseparable_gray run every gray level. The two Color
ramps fail with the unpatched blend.rs. The Luminosity ramp (black over
each opaque gray, upstream's other case) passes either way here: pages
use the u8 pipeline, and that case only failed in the f32 one; it stays
as a guard.

A wrapper without a `CFF ` table must draw exactly what the same font
with no embedded program draws, and not the embedded program. The old
check (some ink on the page) also passed if the program were read
despite the missing table; with the lookup changed to take the first
table whatever its tag, the new assertion fails.

A Type1 font whose FontFile3 has subtype /OpenType (ISO 32000-2 §9.9)
keeps its CFF program in the `CFF ` table of an OpenType wrapper.
CffFontBlob::new rejected the wrapper, so the font fell back to the
standard-font stand-in and the text drew in the wrong face and weight.
The CFF table is now taken from the wrapper, as composite fonts already
do (hayro-interpret patch (69)).
The test wraps the renderer's bundled CFF program in a one-table OTTO
directory at run time (no font file added) and requires the wrapped and
bare programs to give identical pixels; it fails with the fix reverted.
A wrapper without a `CFF ` table still draws, with the stand-in.

An error from rendering a neighbour ahead left it wanted and unqueued, so
each frame queued it again. It is now kept out of rendering ahead at that
scale (drawing it when shown still decides). On the web, where nothing
renders ahead, no render pool is made; picture()'s doc says a page that
fails keeps a picture drawn earlier.

The page shown was drawn through a fresh renderer each time, which parsed
the whole unmarked document on the UI thread; UnmarkedPages now parses it
once and keeps it. An error from rendering a page ahead (the pool retiring
its parser, a cancelled request) no longer marks that page failed: only
drawing it when shown decides, and a page that has a picture keeps it. On
the web, where the pool renders on the UI thread, nothing renders ahead.

The preview showed the page's thumbnail, old marks and all, until the
unmarked page rendered, and one page that failed to render switched the
unmarked preview off for every page. The page shown is now drawn from the
unmarked document straight away at the preview's size; the pages a step
goes to render ahead off the UI thread; a page that fails falls back to
its own thumbnail while the others keep theirs.

The preview cloned and wrote the whole document on the UI thread for every
page it stepped to, and showed a blank sheet while the page rendered.
Document::without_marks now removes the marks of a kind from every page
once per dialog (UnmarkedPages), each page shown renders from it off the
UI thread, and the page's thumbnail stays until it arrives.
