* Viewer: accelerate coarse wheel scrolling (#1072)
Line/Page notches moved a fixed eased step, so a fast spin felt slow.
Accumulate one frame of coarse input per axis, scale by arrival rate
(1.0 idle, up to 6.0 spinning), and apply it directly like precise
touchpad input.

* Viewer: add only the fast-spin surplus on top of egui smoothing
Single notches flow through egui untouched, so isolated input matches
the scroll speed preference exactly; page units are never boosted.

* M3: type an exact zoom into the rail's zoom field
The rail's zoom percentage was a read-only label. It is now a text field:
Enter applies a typed percentage (150, 150%, 62.5 %), Escape or unparsable
input keeps the current zoom. The control channel's zoom option uses the
same parser.

ROADMAP.md, docs/roadmap.md: union of both sides' log lines and milestone rows, each line once.
parity/acrobat-features.toml, crates/xfdf/README.md: next's text, a superset of main's (#1917, #2686 plus #2688).
crates/edit/src/tests.rs: both sides' new tests (#2558 and #3084).
crates/ui-egui/src/editing.rs: the picked picture is cleared on every edit, and a new drawing commits its raster (#3149).
The Hand tool scrolled by the page widget's drag delta from inside the
page view's ScrollArea. egui applies that delta when the area ends, after
the frame's pages are laid out and drawn, so the page showed each move a
frame late and trailed behind the pointer. (Until the page view stopped
animating its scrolls, the delta was also eased in over several frames,
which is the stutter #924 and #1992 describe.) On top of that, the points
the pointer moved before egui tells a drag from a click were dropped, so
the page never caught up with the grab point.
Pan before the area lays the pages out instead: when the page widget is
being dragged with the Hand tool, set the scroll offset from the last
offset minus this frame's pointer delta, or minus everything moved since
the press on the frame the drag is recognised. The page now moves point
for point with the pointer in the frame it moves, and still stops where
it is let go (no fling). Other scrolls (go to page, links, zoom anchors,
compare sync) are untouched and still win when asked for in the same
frame.
* fix(ui): validated signature display, snapshot tab reuse
Signature widgets with layered appearances baked the unverified state
into the page, so a valid signature kept reading 'Signature Not Verified'
while the banner and panel said valid. Validated verdicts are now drawn
into the icon and caption layers in the display copy only: the signed
bytes are untouched, saving keeps the original appearance, and files
without those layers or without a valid verdict render exactly as before.
Other valid signatures still get the verdict mark over their widget,
sharing one style with the Signatures panel, and hide it again once the
appearance itself shows the verdict.
View signed version and View revision opened a new tab on every click,
and every tab showed the document title, so repeats piled up identical
tabs. Repeats now reuse the snapshot tab, snapshot tabs read like their
source plus the suffix in the tab strip, window title and Combine picker,
and carry a notice bar naming the revision with a Close that asks about
saving first.

* Address review comments on validated appearances and trust refresh
Count every field when checking shared appearance streams, so a
caption shared with an unvalidated field is never rewritten for the
valid one alone.
Pick the icon slot by drawing instead of length, and only when a
single layer qualifies. Bare rectangles never count as the icon, and
ambiguous or missing slots fall back to the overlay badge.
Revalidate and invalidate together through one helper, so trusting a
certificate always drops rendered pages. Trust alone still marks
nothing dirty.
Tests: mixed-verdict sharing, longer decorative borders, competing
and doubled layers, capture-before preservation, trust invalidation
without zooming, and signed Session round trips with rendering,
saving and passwords.

* Prove the icon slot geometrically and cover real layered signatures
A lone line drawing is still not the icon: frames and borders span the
box while the status mark lives in a corner of it. The icon now has to
sit strictly inside the appearance frame and cover at most half of it;
anything else falls back to the overlay badge. Widgets without a
measurable frame veto the rewrite the same way.
Tests: parsed extents and inhabitant checks as units, both reported
border repros plus a frameless widget, and real layered signatures
built with cms::sign_detached through Session open, trust, rendering,
save and reopen, plain and password-protected.

* Identify the icon by shape instead of geometry
A lone line drawing is still not the icon, but size and position were
the wrong signals: the real status mark is large, and geometry blocked
it. Frames, borders and panels are rectangles by nature while the mark
is not, so a drawing made only of axis-aligned rectangles is decoration
however it is stroked. Singularity, shared-stream and template checks
are unchanged; anything ambiguous still falls back to the overlay badge.
Tests: rectangularity as a unit, nested line-drawn frames, and a
triangular fixture mark in place of the rectangular one.

* Budget the appearance walk and keep the marks with the bytes
The walk that finds a signature's icon and caption capped depth,
layers and fields, but not the work: a dictionary whose entries all
point at the next one is visited once per entry per level, so a small
hostile file never finishes opening. The walk now counts its visits
and gives up, and a field whose tree cannot be read to the end stops
the whole pass, because a layer we never read may be the one two
fields share and a rewritten shared layer puts one field's verdict on
another field's page. The sharing count is exact again with that: two
widgets of one field pointing at the same appearance claim it once,
or the field vetoes its own rewrite.
A mark used to outlive the bytes it described. A failed display write
left the page showing the file's own caption while the verdict still
claimed its state was drawn; a metadata edit dropped the mark while
the page kept drawing the state, so the badge landed on top of it. The
write fallback now drops the marks and logs the loss, and metadata
carries them over.
Tests: a self-referential appearance tree, which never finished before
the budget, two widgets sharing one appearance, a metadata edit that
keeps its mark, a save that goes through the writer instead of
short-circuiting on the opened file, and the snapshot bar's Close
button pressed for real.

* Cite the new regressions in parity, restore main's installer note
The appearance entry now cites the bounded walk and the save through
the writer, and says what a tree that cannot be read to the end does.

signed installers are planned; main's newer note is taken verbatim.

The jump scrolls to MARGIN - GAP above the page. A page that fits has
nothing to scroll, and egui clamps the offset only after drawing the
frame, so the page showed 14 pt too high for a frame and then hopped
down. Clamp the jump to the scroll range before handing it to egui.
At Fit Page in single-page view, every wheel turn forward drew one
blank frame before the new page appeared.
- Lay out the shown row again after the wheel is read. The jump to the
new page was measured from the old row's place and scrolled both out
of view; going back it came out negative and was clamped, so only
forward turns flickered. The edge-turn deferral that worked around
this goes.
- Prefetch the rows either side of the shown one, so the next page is
rendered before the turn instead of showing blank paper.

- Retain tiles of on-screen pages at both eviction sites in
crates/ui-egui/src/canvas.rs, so a pan or zoom that moves the viewport no
longer discards tiles that were rendered sharp moments earlier.
- Stop dropping a zoom's tiles when zooming out far enough shows the page
whole; that made returning to a visited zoom a cold miss, which re-blurred
the page and re-interpreted it once per tile.
- Bound older-zoom retention by bytes (TILE_BYTES) as well as by count
(OLD_TILES): a tile of a large scan can be 4096 squared, about 67 MiB, so a
count alone ran past the tile allowance.
- Add returning_to_a_visited_zoom_reuses_its_cached_tiles, which fails on the
reverted fix, and cite both view tests in view.deep-zoom-tiles; the entry
stays partial because the 8192 px-per-side cap is untouched.

Wayland compositors leave momentum to the client: libinput reports the
swipe as pixel deltas and the lift as an axis stop (TouchPhase::End), and
the page view stopped dead there (#1708). It now measures the gesture's
speed over its last 0.1 s and keeps scrolling through the #759 1:1 path,
slowing with a 0.35 s time constant.
- No glide for a slow drag, a pause before lifting, zoom or Shift swipes,
single-page paging, or with Animation effects off.
- Any wheel input, click, key, zoom, dialog or the document's edge ends it.
- Off on macOS (it sends its own momentum) and the web; Windows and X11
report no touch phases through winit, so nothing starts a glide there.
Not yet: fingers resting on the touchpad don't catch the glide; that needs
Wayland hold gestures, which the vendored winit doesn't bind.

* M3: follow Windows' Animation effects setting; Smooth scrolling preference
With Settings > Accessibility > Visual effects > Animation effects turned
off, the wheel still eased: egui spreads a coarse wheel step over about a
quarter of a second, for scrolling and for Ctrl-wheel zooming, and has no
switch for it.
- crates/ui-egui/src/motion.rs reads each frame's wheel input the way egui
does, minus the easing, and hands it to the scroll areas and the views
(zoom_delta). A test sums what egui eases and compares it with what is
read at once, and fails if egui stops easing.
- With the system asking for no animations, egui's own animations take no
time and the progress card's bar steps without its sweep.
- The desktop app asks WinRT's UISettings.AnimationsEnabled at launch and
every two seconds of use, so a change applies without a restart.
- Preferences has Smooth scrolling: Use system setting (default), On, Off.
On or Off decides the wheel's scrolling and zooming, and scrolling to a
place, whatever the system says. Saved, settable as smooth_scrolling on
the control channel, translated in all 20 catalogs.
How far a notch scrolls or zooms is unchanged. macOS, Linux and the
browser aren't asked for their setting yet; Off works everywhere.

* M3: rename Smooth scrolling to Animation effects; it decides every animation
The preference also governs Ctrl-wheel zooming, so "Smooth scrolling"
described only part of it. As "Animation effects" (Use system setting, On,
Off) it now decides every animation in the window, the way the Windows
setting of the same name does:
- the wheel's scrolling and zooming, and scrolling to a place (as before);
- egui's own animations, the progress card's sweep, and the chrome's hover
and press washes (new on main, with durations of their own), which used
to follow the system alone or not at all.
Saved and set on the control channel as animation_effects (system, on,
off); the unreleased smooth_scrolling name is gone. The three labels are
retranslated in all 20 catalogs.

* Tests: the app's two real-GPU tests take turns (FreeBSD SIGSEGV)
FreeBSD CI died with SIGSEGV in the pdfcraft binary's tests on this branch
(d4b928f1). The log shows a_gpu_error_while_a_window_is_set_up... (started
first, still running) and pipeline_creation_error... (started shortly
before) both in flight when the process died: two test threads inside the
graphics libraries at once. Nothing else still running was native code.
Both now take one lock for the whole test, as the UI tests already do for
the same reason (crates/ui-egui/tests/view.rs). Each takes about two
seconds with a device, which is why they can overlap.
The FreeBSD job has been failing at the same step with the same exit code
on main (84a75eae, 4a1e205f, 3d2bdfe7: every completed run since #1042
added the second real-GPU test) and on unrelated PRs. Their logs weren't
available to confirm it is the same crash.
Not reproduced locally (no FreeBSD machine here); the next FreeBSD run is
the check.

* Heavy pages: cull off-tile images, cache decodes, preview backdrops, calmer queues
A large CAD sheet (page 24 of the benchmark file: ~5050 pt wide, 2104
images, 9 MB of content) cost a full page interpret per tile: 4.3 s for a
1024 px tile at 1000%, 10.5 s for the whole page, and a storm of renders on
every pan frame. Tiles now cost 0.6 s, the sheet is covered by a handful of
large tiles, and gestures no longer queue work faster than workers finish it.
- Vendored hayro patch (10): skip images whose stream-size box misses the
canvas before decoding them, so a tile no longer decodes, resamples and
rasterizes every image on its page. Pixel-identical; the skip regression
test now covers images too.
- Vendored hayro-interpret patch (23): decoded image pixels shared across
renders through the interpreter cache, keyed by stream and decode target
size within a 64 MiB budget.
- Preview renders (hayro patch 11, RenderRequest::preview through to the
device): backdrops, thumbnails, grid cells and signature-drag backgrounds
skip images under 16 device px. Tiles, whole pages, print and export always
draw everything. Previews may differ by those pixels; finals don't.
- Viewer: zoom/pan settle holds apply only to pages whose raster proved slow
(slow_pages, 500 ms), so fast pages render with no added latency; tile sides
grow with zoom and page size (giant sheets need ~8 tiles, not ~28), queued
center-first and keyed by exact coordinates; Edit-text outlines capped.
- vendor/README.md records the new patches with their tests.

* Decoded-image cache: key every decode input, survive a poisoned lock
The key was the dictionary's bytes and the target size, so two images with byte-identical
dictionaries (uncompressed, one size) shared pixels, and an image drawn under a transfer
function reused pixels decoded without it. DecodedImageKey now holds the dictionary's place
in the document (its data follows it), its bytes and object, mask/stencil/raster output,
interpolation, the target size and preview or final quality; images under a transfer
function and inline images (named colour spaces, dictionaries in content streams) are not
cached, and an image over the budget is never kept. A poisoned lock decodes uncached
instead of panicking. Soft masks: the per-renderer cache can't carry a preview mask into a
final render (documented). Regression tests for identical dictionaries, preview then final
through one cache, and transfer functions.

* Content edits on heavy documents: narrow refresh, cached appearances, per-page invalidation
Every content edit (drag, resize, retype) on a large document ran a full
synchronous refresh on the UI thread: a whole-file re-inspection plus a
redraw of every missing annotation appearance, then dropped all page
rasters. On a 72 MB / 202-page CAD file with 27k appearance-less
annotations each commit cost ~1.5 s before anything re-rendered. Now ~0.3 s.
- New Scope::Content for edits that touch only page content, resources and
added content/marks (move/resize/retype/images/added items/marks): the
page tree, annotations, fields, links, outline and fonts are unchanged,
so refresh_content rebuilds working bytes, display bytes and renderer and
validates with a light check_pages (parse plus page count, keeping the
roll-back guarantee) instead of a full inspect. added/marks are re-read
only when the edit can change them; undo/redo re-read both.
- AppearanceCache in pdfcraft-annot: built display appearances are reused
while no annotation edit runs (content edits leave every annotation
dictionary alone); cleared on comment, structural and full refreshes.
set_appearance is split into build/apply halves so a hit skips the draw.
- check_pages in pdfcraft-render: light post-edit validation.
- Viewer: single-page content edits invalidate only their page
(page_changed); other pages keep tiles, text and thumbnails.
- XFA dataset sync now also runs for content edits.

* Viewer: touchpad scrolling tracks the finger 1:1 (#759)
A precision touchpad sends pixel-precise `MouseWheel` events. On Windows
they arrive with no `TouchPhase::Start`, so egui never takes its
no-smoothing "in touch" path and eases any delta of 8 px or more over
several frames, leaving the page a frame behind the finger.
The page view now applies precise (Point-unit) wheel input itself, 1:1,
through the same un-eased scroll path as keyboard and middle-button
auto-scroll, and suppresses egui's eased copy for a short window so its
internal easing tail neither doubles nor trails the motion. A coarse
mouse wheel (Line/Page units) keeps egui's smoothing, which is pleasant
for chunky notches, and single-page paging still owns the vertical axis.
Regression test: one 200 px precise swipe scrolls the full 200 px at
once (an eased path would ramp there over ~0.1 s) and leaves no drift.

* Viewer: Continuous scrolling is an independent checkbox over the base layout (#752)
Page display matches Acrobat: the base layout (Single page or Two-page
view) is a radio choice, and Continuous scrolling is a separate checkbox,
so every combination is reachable. This also adds the previously missing
"Two-page view, one spread at a time" mode.
`PageLayout` now has just `Single` and `TwoUp`; a separate `continuous`
flag on the view (and on the default view preferences) decides whether it
scrolls. A single `display_token` ("single" | "continuous" | "two-up" |
"two-page") serialises both for settings and the control channel, keeping
the earlier `continuous`/`single`/`two-up` names working and adding
`two-page` for the new mode. The PDF's own page-layout request now maps
to the right (layout, continuous) pair, including plain TwoUp.
- View ▸ Page display and the rail menu show two radios plus a Continuous
scrolling checkbox; Preferences gains a default Continuous checkbox.
- `view.continuous` toggles the checkbox; `view.layout.single` /
`view.layout.two_up` switch the base layout without touching it. The
former `view.layout.continuous` command is gone (its state is Single +
continuous); the `layout`/`default-layout` options and a new
`continuous` option cover scripting.
- Not scrolling, the wheel and the arrow/Page keys turn whole spreads in
Two-page view, and only the current page or spread is laid out.
Tests: new `notches_turn_two_page_spreads`,
`two_page_view_shows_one_spread_at_a_time_until_continuous`, and updated
layout/command/persistence tests; the `view()` helper takes `continuous`.

* D5: README for cos and engine, and an honest cos status line
Thirteen crates have no README, although the session protocol tells every session to read the README of the crate it is touching. These are the two biggest: cos is where every hostile file lands first, and engine is the whole API surface a frontend gets.
Each states its layer and the rules that bind it, sketches the API against the real signatures, and ends with what is deliberately not done. The cos README spells out the clone-is-a-snapshot property and why both writers return bytes rather than taking a sink; the engine README spells out the four-step editing model that makes what you see what Save writes.
Also corrects the module doc on cos/src/lib.rs, which still said encryption and object-stream output for full saves were not done. Both shipped: security.rs handles R2-R6 with crypt filters and /EFF, and SaveOptions::object_streams defaults to true.

* View: keep earlier tiles on screen while a zoom's new tiles render
Zooming a tiled page (larger than 4096 device pixels) dropped every tile
of the previous scale at once, so each zoom step fell back to the
2048 px backdrop until the new tiles arrived: the page went blurry on
every frame of a pinch. Tiles are now keyed by scale; those of earlier
zooms stay (nearest scale on top, at most 64) and are drawn stretched
under the current ones until those cover the page. Entering the tiled
range also keeps a whole-page raster sharper than the backdrop instead
of replacing it with the backdrop.

digits into u64 using wrapping arithmetic. Integer mantissas exceeding
u64::MAX wrapped modulo 2^64, severely corrupting page dimensions
(e.g., 3874.96 pt became 185.61 pt, rendering as a warped ribbon).
Accumulation now uses checked arithmetic: trailing fractional digits
exceeding u64 capacity are safely ignored without incrementing decimal_shift.
This preserves full IEEE-754 f64 precision while preventing overflow for
numbers with arbitrary numbers of decimal places.
Includes:
- Unit test in hayro-syntax with reported values and a 50-digit fraction.
- Synthetic PDF regression test in pdfcraft-render verifying inspect().
- Vendored patch (6) documentation in vendor/README.md.
Fixes#199
* M2: bound page-label work and output before applying labels
Share bounded PDF Roman and repeated-letter formatters between inspection
and editing. Bound tree traversal, raw and decoded prefixes, individual
labels and aggregate label output, with checked numbering arithmetic.
Stage inspection labels before applying them and retain physical page
numbers with a warning when optional labels cannot be processed. Reject
unsupported label edits before changing the document tree.
Add synthetic limit, cycle, Unicode, numbering and atomic-edit regressions.

* Never crash: mesh shadings can't exhaust memory or run for minutes
`cargo xtask fuzz` (with the dash, JBIG2 and decompression fixes in
place) found a page whose Coons patch shading (type 6), a 147-byte
stream with 1-bit coordinates decoded onto +-40000, took the renderer
past 3 GB. hayro-interpret samples mesh shadings (types 4-7) pixel by
pixel over each triangle's device-space bounding box into a map, with
nothing but the u16 cast bounding it: up to 65536 x 65536 entries for
one triangle. A synthetic single patch passed 6 GB in six seconds; ten
thousand triangles that each cover half a 1000 x 1000 page ran for
minutes. Two rounds of review of earlier versions found more: every
patch was cut into 722 triangles (about 150 KB) before anything limited
them; a lattice mesh with `/VerticesPerRow 0` pushed empty rows forever,
and one with 4294967295 read the whole stream into one row; a mesh
painted a thousand times was triangulated a thousand times; and the
first caps cut content without a word.
Vendored hayro-interpret patch (18):
- `ShadingPattern::encode_within(area)`: the vendored hayro renderer
passes the area it will actually draw (the path's bounding box on the
canvas, which it already computes) plus a pixel for texels at a
fractional edge, and triangles are sampled only inside it, so the map
holds at most that area's pixels.
- `TriangleSampler`: at most 8 visits per pixel of that area plus 4 per
triangle in it. A triangle's bounding box is about twice its area and a
sub-pixel triangle's is at most 2 x 2 pixels, so tiling meshes and
small dense ones (a patch in a few pixels is 722 triangles) still
shade completely; overlapping ones stop.
- Coons and tensor-product patches are triangulated one at a time.
- Meshes hold at most `MAX_MESH_PATCHES` (2^16; a 200 x 200 gradient
mesh is 40 thousand) patches and `MAX_MESH_TRIANGLES` (2^20)
triangles, and a lattice needs two (ISO 32000-2 8.7.4.5.6) to 2^19
vertices per row.
- A page samples at most `MAX_PAGE_MESH_TRIANGLES` (2^25; the 200 x 200
mesh is 29 million) mesh triangles in all, reset per page like the
existing paint budget.
- Each of these cuts logs a warning.
`encode()` keeps its signature; with no area it samples within a fixed
2^24 visits.
Synthetic regression tests in render:
- `mesh_shadings_far_off_the_page_render`: a Coons patch and a triangle
mesh decoded onto +-40000 render and the rest of the page draws; a
patch on the page, the part of the huge one that covers it, and a
patch filling a 4 x 4 pt rectangle as a pattern are all shaded.
- `many_overlapping_mesh_triangles_finish`: 10,000 triangles each
covering half of a 1000 x 1000 page finish, and are drawn.
- `mesh_shadings_with_many_patches_or_no_rows_finish`: 40,000 patches
beside the page, and a lattice with `/VerticesPerRow 0`.
Red on main (out of memory, killed at 3.9 GB). Each part is pinned by a
mutation: no visit budget stalls past 60 s; no clip leaves the covering
patch unshaded; no per-triangle allowance leaves the small patch
unshaded; triangulating all patches first runs out of memory (killed at
5.8 GB); no rows check runs out of memory.

* Never crash: decompression bombs can't exhaust the renderer's memory
The renderer's parser (vendored hayro-syntax) decoded Flate, LZW and
RunLength streams with no output limit. A 2 MB page whose content
stream inflates to 2 GB, or whose 8 x 8 image does, took `pdfcraft-cli
render` and `text` past 3 GB in under a second, and a few more MB of
file scale it further. On the desktop that is the first-page render of
an emailed PDF, and the allocation-failure abort takes every open
document with it. Our own layers already bound single streams (lopdf's
load-time decoding at 256 MiB, cos at 1 GiB), so `info` stays at a few
MB; the renderer path didn't. Random mutation almost never makes a
high-ratio stream, so `cargo xtask fuzz` doesn't find this; found by
hand while triaging the fuzz run.
Vendored hayro-syntax patch (6):
- `decode_limit` gives each filter an output limit, and Flate (both
flate2 and the fallback inflater), LZW and RunLength never write past
it (the buffer can still grow to under twice it):
`MAX_DECODED_STREAM`, 256 MiB, lopdf's figure; or, for the last filter
of an image whose size, bits per component and components are known,
twice its pixel bytes (a PNG predictor tag byte per byte at most),
capped at 1 GiB. Earlier filters in a chain produce compressed data
and get the general limit.
- `Stream::decoded_within(max)` for callers that budget.
- A page's `/Contents` array shares one `MAX_DECODED_STREAM` (naming one
bomb twenty times decoded 5 GB), reserving exactly what it appends.
Vendored hayro-interpret patch (18):
- The content a page holds at once (its contents, and the forms, tiling
patterns and Type 3 glyph procedures being painted) stays within
`MAX_PAGE_CONTENT`, 512 MiB, reset per page like the existing paint
budget. Forms nest fifty deep and each level kept its content while
the next ran: a form painting itself around a 256 MiB stream would
have held over 12 GB. Each level gives its bytes back when it is
dropped, so content painted again and again keeps drawing, and a
stream without filters (borrowed from the file) costs nothing.
- Type 0 sampled functions read every sample into a 4-byte value and
then a table entry: 256 MiB of 1-bit samples asked for over 8 GB. They
now take at most 2^21 table points and 2^23 values (the largest real
tables, DeviceN tint transforms such as 33^4 points x 3 outputs, are
1.2 million and 3.6 million), counted with checked arithmetic, and
read no further than `/Size` asks. `/Size 0` no longer underflows
building the default `/Encode`.
Three rounds of independent review found the aggregate cases, buffer
doubling past the limit, a chain/predictor shape the first image limit
would have truncated, the Type 0 amplifier, and a first, cumulative
budget that would have dropped legitimately repeated content, and a
first Type 0 cap low enough to refuse real tint transforms; all fixed
here.
Measured in a release build (render; OS peak commit):
- content stream inflating to 2 GB: 389 MB, 0.3 s
- 8 x 8 image inflating to 2 GB: 4 MB, 0.2 s
- /Contents naming it twenty times: 516 MB, 0.3 s
- a form painting itself around it: 644 MB, 0.4 s
Synthetic regression tests in render (flate2 is a new dev-dependency
there, already in the workspace):
- `decompression_bombs_stop_at_the_stream_limit`: 288 MiB bombs through
flate2, the fallback inflater (a stored block with a wrong length
check, which flate2 refuses and the fallback accepts), LZW and
RunLength each decode exactly 256 MiB, and at most 128 bytes as an
8 x 8 image.
- `page_contents_and_nested_forms_share_one_budget`: three /Contents
references decode one stream's worth; a self-painting form finishes.
- `content_painted_again_and_again_keeps_drawing`: a 2 MiB form painted
300 times draws the 300th time.
- `sampled_functions_with_billions_of_samples_are_refused`.
Ten mutations each turn them red: no limit at all; no limit in flate2,
the fallback, LZW, RunLength or for images; an unshared /Contents limit;
no page budget; no refund on drop; no Type 0 sample cap. (Taking a form
out of the budget no longer compiles: its content is the budget guard.)

Every destination was reduced to a page index (`dest_page` in the
inspector), so a bookmark written as [p1 /XYZ 0 420 0] went to the top
of page 1 instead of putting y 420 at the top of the window, and /FitH,
/FitV, /FitR and an /XYZ zoom were ignored.
Destinations now keep their view (ISO 32000-2 §12.3.2.2):
- render: `DestView` (Top, Xyz, Fit, FitH, FitV, FitR) parsed from
explicit arrays, /D dictionaries and named destinations (/Names
/Dests and /Dests). `OutlineItem` gains `view`; `LinkTarget::Page`
carries it. Missing, wrong-typed or non-finite operands are null, a
zoom that isn't positive keeps the zoom, and an unknown type or a
/FitR without four numbers falls back to the page top.
`PageInfo::dest_fraction` maps a user-space point to the displayed
page through the crop box origin, /Rotate and the view rotation,
clamped to the page.
- ui: `DocView::go_to_dest` applies it for bookmark and link clicks
(and so for `ui.click` on the control channel): /XYZ puts (left, top)
at the window's top-left (beside the quick-action gutter) at its
zoom; /Fit, /FitH and /FitV switch to fit page, width and height with
top/left at the edge; /FitR zooms so the rectangle fits, centred. The
/FitB* content box is read as the whole page.
Tests: operand parsing incl. hostile values, a fixture with every form
(named, GoTo, wrong types, huge numbers, no page), point mapping under
crop offsets and rotations, go_to_dest state, and kittest bookmark and
link clicks checking the point lands at the window's top.

The ui-egui integration tests drive the shell by its English labels, and
`i18n::system_lang` returns `Lang::EN` under `cfg!(test)` so they can. That
only covers the unit tests: an integration test links the library as it
ships, where `cfg!(test)` is off, so `PdfCraftApp::new()` leaves `language`
on `auto` and the shell is drawn in the system language. On a Spanish
Windows eleven of the test binaries fail; a French, Russian, Chinese,
Japanese, Portuguese, Czech or Telugu machine does the same. CI never sees
it because its locale is English.
`tests/theme.rs` and `tests/create.rs` already pin the option; the other
119 harnesses now do too, and the comment in `system_lang` says why, so a
test copied from an existing one keeps the line.
Also `i18n::tests::windows_display_language_query_returns_a_locale_tag`
treated the return of `windows_ui_language()` as a single tag. It is the
preferred-language list, one tag per line, as `first_supported` reads it,
so on a Windows with two or more display languages the assertion tripped
over the newline. It now checks the shape of every line.

* Forms: round required-field border on radio buttons; Highlight fields is remembered
#260 (page 8) compares PdfCraft with Acrobat, which outlines required
checkboxes and radio buttons in red. Adobe's documentation says that
border shows "when the Highlight Existing Fields button is selected",
which PdfCraft already did (View: Highlight fields). Two differences
remained:
- The red border was a rectangle for every widget, so a round radio
button got a square around its corners; Acrobat's follows the button.
Radio buttons now get a round border and tint.
- Acrobat keeps Highlight existing fields as a preference, while
PdfCraft forgot it for every document. The choice is now remembered
for the next document and the next session (ViewDefaults and
settings). It still defaults to off, and red borders still appear
only while fields are highlighted.
Tests (view.rs): required_radio_buttons_get_a_round_red_border (the
widget's corner, outside the circle, is not red; on main it is) and
field_highlighting_is_remembered (a second document and a restored
session open highlighted; on main the second document didn't). The
form.highlight-fields parity entry cites both.

#260 (page 9) reports text that looks softer than in Acrobat once zoomed.
The page was rendered at the zoom's device scale rounded to 1/64
(render_scale, to spare re-renders on tiny fit-width changes), and the
texture was stretched onto the page's layout rectangle, whose corner
usually isn't on a whole physical pixel. Every line and glyph went
through linear resampling: at 87 % on a 2x display the raster was 0.32 %
too small for its rectangle, and #260's page 9 lost 7.9 % sharpness
against a direct render (1.7 % at 137 %; 0 at 150 %, which happens to
quantize exactly).
The page now renders at the exact device scale (tags resolve 1/65536 of
a scale step instead of 1/1000), each page rectangle starts on a whole
physical pixel, and a raster at the current scale is drawn at its own
pixel size from there, whole page or tile. A raster from an older scale
(mid-zoom) and the low-resolution backdrop under tiles still stretch, as
before. With the fix, page 9 on screen matches a direct render exactly
(mean difference 0.00/255 at 87 % and 137 %, was 6.30 and 2.66).
Test: view.rs::page_raster_maps_one_to_one_onto_screen_pixels renders a
page of 0.5 pt lines at 87 % with 1 and 2 pixels per point and compares
the screen with the page rendered directly at the exact scale. On main:
mean difference 69.5/255, max 216. Now: under 1, max under 16.

* M3: add middle-click autoscroll
Co-Authored-By: Codex <noreply@openai.com>
* M3: keep middle-click autoscroll toggled after release
Keep scrolling enabled after releasing the wheel, including when the
pointer moves before release. Anchor speed to the initial press event,
so movement later in the same frame cannot shift the starting point.
Cover toggle behavior and increasing speed with distance in both views.
Co-Authored-By: Codex <noreply@openai.com>
* M3: increase middle-click autoscroll speed
Double scrolling speed at the same pointer displacement and raise the
speed cap proportionally, preserving the dead zone and click toggle.
Keep the sustained-scroll fixture visible at the faster response.

* M3: match Chromium middle-click scrolling
Use a 15-point dead zone and Chromium's nonlinear distance-to-speed curve
in the document viewer and Organize Pages. Request continuous redraws so
scrolling follows elapsed frame time and preserves fractional movement.
Keep click toggling, cancellation, and the existing marker unchanged.
Cover reference speeds, pathological inputs, pause/resume, and consistent

The app, crates, binaries, bundle id, packaging, icons, screenshots and docs are now
PdfCraft / pdfcraft (repo storytold/pdfcraft). On first launch the desktop app moves the
PrintCraft settings and crash-recovery folders to the new name, and both apps read settings
saved under the old storage key, so upgrades keep recent files, preferences and unsaved work.
The signing test fixtures keep their PrintCraft subject names (they are binary).

On GitHub's Windows 11 ARM64 runner (no GPU, so wgpu uses Microsoft's WARP)
tests/view.rs died with STATUS_ACCESS_VIOLATION in about 1 run in 4. A crash
dump puts it inside WARP's pixel-shader JIT
(d3d10warp!PixelJitProgram::ClassifyVars, on WARP's own thread pool) when the
two tests that render pixels compile shaders on separate devices at once.
Single-threaded, or each test alone, it never crashed (180 runs); bigger
thread stacks didn't help (6/30 vs 7/30), so it's that race, not our code.
The app has one device on a real GPU and can't hit it.
Those two tests now hold a per-binary lock for their whole run (taken before
the harness, so released after its device drops). Other test binaries render
from at most one test.
