crates/render/src/raster.rs: main's tests plus the PR's #2970 test after the knockout test
vendor/README.md: main's rows with the PR's rewording of hayro patch 18
crates/render/src/raster.rs: both new tests (#2975 stencil masks, #2971 knockout groups)
vendor/hayro/src/renderer.rs: set_paint returns main's PaintSetup; the PR's knockout erase early return wraps its clip in PaintSetup::Clip
vendor/README.md: main's rows plus the PR's hayro-interpret patch 39 and hayro patch numbered 22 (19 is #3296's), with tests
vendor/hayro-interpret/src/pattern.rs: ShadingPattern::new takes the default colour spaces (#3018) and no opacity (this PR); without_opacity (#2977) and set_alpha both kept
Conflicts:
- ATTRIBUTION.toml: ours (sha256 lines only); hashes recomputed at the end of the track
- crates/engine/Cargo.toml: main's workspace chrono entry, plus the PR's pdfcraft-testkit dev-dependency
vendor/hayro/src/renderer.rs: main's PaintSetup::Clip match with the PR's fill paint (is_stroke false) and comment
vendor/README.md: main's row plus the PR's hayro-interpret patch and test, numbered 46 (35 is #3296's)
crates/cos/src/document.rs: #2220 moved the header scan into object_headers; it also returns the position after `obj`, and reconstruct applies this PR's /XRef candidate check (same 1024-byte window) to each header there. Tests: kept both sides.
vendor/hayro-interpret/src/encode.rs: both sides; a pixel sampled by either test (corner held, or centre covered) widens the mesh extent from #3296
vendor/README.md: main's row plus the PR's patch 36 and its test
Vendored hayro-interpret refuses an embedded font whose `post` table
version isn't 1.0, 2.0, 2.5 or 3.0 (a guard from pdf.js issue 9462).
ScanSoft PDF Create! writes the version of every font it embeds with its
16-bit halves swapped (`00 00 00 03` for 3.0), so those fonts were refused
and their text drawn with a substitute: Hebrew came out as Latin
look-alikes or not at all.
1.0, 2.0 and 3.0 with swapped halves are now accepted too; any other
unknown version is still refused. PdfCraft patch (38) in vendor/README.md.

TextDevice::draw_glyph called std::env::var_os twice for every glyph. getenv scans the whole environment under a lock, so text extraction paid for it on each glyph. Read the variable once into a OnceLock.
* fix(render): read each object stream's index once (vendored hayro-syntax patch 22)
`XRef::get_with` parsed an object stream's whole index of `objnum offset`
pairs again for every object it fetched from that stream, so reading all of a
stream of N objects took N² steps. Firefox keeps every object of a page in one
stream: the pdf.js corpus file bug1978317.pdf (65,542 objects in one stream)
took 37 s to draw and 40 s to extract its text, and was a known timeout in the
robustness baseline.
The parsed index is now kept per stream, beside the decoded stream data it
indexes (`ObjectStreamIndexes`), and never cleared, as that data isn't. A
malformed index is remembered as malformed; `/N` or `/First` that can't be
read (a reference that can't be followed while another stream loads) is not
remembered. An offset past `usize` is malformed instead of wrapping. A poisoned
lock is still used: entries are inserted whole.
Release build, Linux: bug1978317.pdf draws in 0.5 s (was 37 s) and extracts
its text in 1.9 s (was 40 s), and leaves the baseline's known timeouts;
40,000 pages in one stream open in 0.2 s (was 54 s).
`raster::tests::objects_in_one_large_object_stream_are_read_in_linear_time`
times out at 20 s with the fix reverted and passes in 0.2 s with it.

* test(render): an object stream offset past usize is malformed, not a panic
Review follow-up on #2427. Mutation testing by mtlcl410 found that replacing
patch (22)'s `checked_add` in `read_object_stream_index` with a plain `+`
survived every test, although in a debug build that `+` panics on the very
input it guards against (and wraps in a release build). Their test pins it:
it fails with "attempt to add with overflow" under that mutant and passes on
this branch.

* Release: PdfCraft v0.11.0
- Bump the workspace to 0.11.0.
- Fix main's red CI (cargo-deny): update rustls-webpki 0.103.15 -> 0.103.16
(RUSTSEC-2026-0382) and webpki-root-certs 1.0.9 -> 1.0.10 (RUSTSEC-2026-0383),
both reached through winprint's sigstore build dependency.
- `cargo xtask version set` now moves the workspace crates' pins in
[workspace.dependencies] with the version; before, `cargo update --workspace`
refused the bump and the pins had to be edited by hand.

* Tests: a healthy private retry may answer during the watchdog pass that scheduled it
shared_timeouts_retry_healthy_pages_privately_before_blacklisting failed on
CI (PR #3893): the try_recv that runs the watchdog spawns the private retries,
and page 1's retry has no gate, so on a loaded runner its healthy result
arrived before that same call read the channel. Accept that early answer
(page 1, no error) and use it as the healthy result; an error still fails.
Reproduced by sleeping 300 ms after the watchdog in try_recv: the old test
fails every time, the new one passes.

A bookmark made in the app always went to the top of the page. It now goes to
the top-left of the selected text, or with nothing selected to the top of the
window, as /XYZ left top null: the reader's zoom is kept, and with only the top
pinned so is the horizontal position.
- render: PageInfo::xyz_for_view, the inverse of dest_fraction. It pins only
the coordinates given; on a page turned a quarter the displayed y decides the
user left and the displayed x the user top.
- organize: add_bookmark_at and OutlineError::BadPosition (a coordinate that is
not finite is refused before anything changes).
- engine: Edit::AddBookmark takes left and top (None, None is the page top, as
before).
- automation: bookmark_add takes top and left in points from the top-left of the
displayed page, as bookmark_list reports them, bounded and refused when not a
usable number.
- ui: DocView::bookmark_position. It follows the window's vertical when the view
is turned a quarter (View > Rotate View), picks the selection's corner that
shows at the top-left, and in a spread of unequal pages uses the page that
crosses the window's top edge.
- parity: organize.bookmark-add evidence and what is still missing.
Once drawn, a line or arrow could be moved but not changed: selected, it showed a frame and
no handles, so a wrong length or angle meant drawing it again. A selected line, connected
lines, polygon or cloud now has a handle on each end or corner instead of the frame; dragging
one moves that point (Shift holds it to 45° from the point before), the new shape is drawn
while dragging, and the release is one undo step. The drawing tools keep drawing from an end
(a new line starts there); the Select and Fill & Sign tools pick the handles up.
pdfcraft_annot::set_points sets /L or /Vertices, lets /Rect follow with room for the width
and arrowheads (the rule a new comment is drawn with) and draws the appearance anew;
measurements keep the points they measured, locked comments their shape. Edit::ReshapeAnnotation
("Reshape comment"), comment_edit `points`; the comment list (Summary, DocInfo, comment_list)
carries a line's ends and a polygon's corners.

PageText::nearest measured the distance to each glyph's axis-aligned bounding
box. In sheared or turned text that box is wider than the glyph and overlaps its
neighbours, so a pointer on a letter was also inside the box of the letter before
it, at distance 0, and the earlier glyph won. A drag ending on the last letter of
a word or line then ended one or two letters short.
A glyph whose drawn em box (quad) holds the point now wins, the nearest centre if
several do. With no quad hit the bounding-box distance still decides, so pointers
past a line end or between lines behave as before; a tie there goes to the nearer
centre rather than the first glyph.
Tests: pdfcraft-render lib 312 -> 314. The sheared and 45-degree test fails on
the old hit-test (glyph "i" resolves to the glyph before it) and passes now.
pdfcraft-ui-egui text_select: 14 pass.
FredApps's note on #3327: five points that are all on the bounding box's
corners still need not trace the rectangle. Three sides and a step back
along the third --
10 10 m 30 10 l 30 30 l 10 30 l 30 30 l S
-- visits every corner, so it was taken as the box and stroked with a
left side the path does not have.
path_as_rect now asks what a rectangle actually is: four distinct
points, each step from one to the next along a single axis, and the last
point back at the first (written as the fourth LineTo or as ClosePath).
That is a rectangle and nothing else is, so the corner test and its
off_corner flag are gone -- four points of an axis-aligned traversal are
necessarily the corners of their own bounding box. A degenerate path,
whose points are not distinct, now takes the general route as well,
where it painted a zero-width or zero-height rectangle before.
The vendored-patch table has the row this change was missing: without
it a re-vendor of hayro-interpret would drop the patch silently, which
is the other half of FredApps's review.
Any value in a PDF may be written as an indirect reference, the tagged
flag included: `/MarkInfo << /Marked 9 0 R >>` with object 9 holding
`true` is valid, and veraPDF's corpus has pass files that write it that
way. Both readers of the flag tested the reference itself, so such a
document was reported as untagged:
doc_info "tagged": false
Accessibility Checker "The document isn't marked as tagged
(MarkInfo Marked)"
Both now resolve the value first. On a pair of otherwise identical
tagged pages, one with `/Marked true` and one with `/Marked 8 0 R`:
before direct: tagged true indirect: tagged false
after direct: tagged true indirect: tagged true
and the checker reports the finding for neither.
A document with no flag at all still fails the rule, which the test
asserts alongside, so this does not turn the rule into one that always
passes.
Fixes#3671.
A glyph narrower than a twentieth of its height was matched as a fake-bold
redraw by a fifth of its height, so in OCR text layers squeezed to 20 Tz or
less the second l of "Hallo", and at 10 and 5 Tz the tt, ss, mm and ff and
letters repeated two or three places on, were dropped. Every glyph with a
width is now matched within half of it; only zero-width marks keep the
height-based distance.
UniJIS-UCS2-HW-H maps code 0x0020 to CID 231 / U+2002. The OpenType
substitute for a non-embedded Japanese CID font lacks that glyph, so
.notdef boxes were drawn. Type0Font::map_via_unicode now falls back to
the substitute's ordinary-space glyph for explicit spacing characters
its charmap lacks. Native and variation-selector glyphs keep priority;
PDF advances and Unicode text are unchanged.
Fixes#3601.

Review on #3239: a name that only numbers the glyph (C39, c251) says
nothing about the character. Reading it as the code's StandardEncoding
character invents text wherever the font's /Encoding puts the glyph
elsewhere: with /C1 at 233 it extracted O-slash for a glyph drawn as
e-acute. numbered_glyph_name and the fallback are removed; the AGL
specification's full mapping stays.
The test puts one glyph per line: the test font has none of these glyphs,
so they have no width, and on one line a later 'fi' sat on the first and
was dropped as its fake-bold copy once the guessed glyphs between them
were gone.

A font naming a Latvian comma-below letter by its code point (/uni0136) or by
the glyph list's name for it (/Kcedilla, /Gcedilla...) still drew nothing:
the name resolves to the cedilla name the glyph list prefers, which the
composite table does not hold. The thirteen comma-below letters are now
looked up by character, which also replaces the special case for U+021A and
U+021B. T and t with a cedilla (U+0162, U+0163) are not in that table and
keep their cedilla.
Raised by CodeRabbit on the PR.

The stand-ins for the standard fonts (PDFium's Foxit fonts) have neither the
comma-below letters nor a commaaccent glyph, and the composite-letter patch
left comma accents out. A non-embedded font naming /scommaaccent therefore
drew nothing, which is the blank "si" left in Romanian XFA forms, and
/tcommaaccent drew a cedilla through the glyph list's alias to U+0163.
Romanian s/S/t/T and Latvian k/K/l/L/n/N/r/R/G with a comma below are now
built from the letter and the font's comma, scaled to three quarters and set
just under the baseline, moved back along the slant in italics. The uni021A and
uni021B names of T and t with a comma below, which the glyph list
does not name, resolve by code point. Lowercase g with its turned comma above
is still not built.

While a handle of a Fill & Sign line, check, cross, dot, typed signature
or comment stamp was dragged, only the selection frame followed the
pointer; the stamp kept its old size (or place) until release. Image
signatures already had a live layer. Every stamp now gets one: the page
without the stamp, and the stamp drawn alone on a transparent page,
whose pixels are stretched with the frame. Resizing a stamp only changes
its /Rect, which its appearance is stretched to fit, so the preview is
what the release produces.
- render: RenderConfig.transparent clears the page to transparent.
- annot: isolate_annotation leaves a page showing one annotation alone.
- engine: Document::stamp_preview builds the two read-only layers; the
page beneath gets the appearances drawn for comments without one.
- ui-egui: the signature drag layer covers every stamp, rendering the
stamp's own tile sharp at the current zoom.
