scale_at converted every number of a viewport's /BBox before checking it
had four, and read every viewport the page listed, so many viewports
sharing one long box array took time proportional to their product. A box
of any other length is skipped unread, and at most 1024 viewports are read,
the most set_scale gives a page.
Every Do operator resolved the stream's /XObject resources again, and
resolving a direct dictionary copies it, so a large direct XObject
dictionary and many short Do operators multiplied the copying. The
dictionary is read on the first Do and kept for the rest of the stream.
Snap geometry charged decoded bytes only on success, so a /Contents
array repeating one stream that inflates past the 16 MiB limit ran that
inflation for every entry without spending any budget. A tolerant decode
fails only on an unsupported filter or after producing the remaining
budget, so a failure now spends the rest of the budget and later parts
are skipped as truncated.
The listing read a measurement for every /Annots entry, so one annotation
referenced many times, or many small annotations sharing one indirect
2048-point vertex array, multiplied its points and text in memory. The
listing skips annotation references it has already read and stops,
marked truncated, once the kept points and text pass 32 MiB.
The Measure panel's drawing scale had its page side fixed in PDF points, so
"1 = 50 mm" was stored as 1 pt = 50 mm and every length came out
72 / 25.4 = 2.835 times too big (a 1:50 plan needed 50 x 25.4 / 72 = 17.64).
The page side now carries a unit (pt, in, mm, cm). It defaults to the
real-world unit, and to the display unit when that is not one of the four.
Scale::ratio converts it to points before building the /X, /D and /A number
formats (ISO 32000-2 12.9) and writes /R as entered ("1 mm = 50 mm").
measure_scale takes the same ratio through page_distance and page_unit.
Scales read from files, Scale::calibrate and units_per_point are unchanged.
Fixes#2752
55 files hand-rolled the same serialiser -- number the objects, record each one's offset, emit a
classic cross-reference table and a trailer -- 111 times over. The object bodies are properly the
business of the crate under test; the envelope around them is not, and every copy is a place for a
fixture to be quietly wrong in a way that makes a test prove less than it appears to.
`pdfcraft-testkit` holds that envelope. It has no workspace dependencies on purpose, so the crates
at the bottom of the layering can use it without a cycle, and it returns bytes rather than a parsed
document for the same reason.
The builder is byte-identical to the serialiser it replaces, asserted against a verbatim copy of
the old code across versions and trailer variations, because a migration that changes a fixture's
bytes silently changes what the test using it proves. Watched failing by breaking the free-entry
generation: three tests caught it. The one intended difference is that an empty stream dictionary
gives `<< /Length N >>` rather than a doubled space.
Migrates cos, measure and redact: 111 copies in 55 files becomes 108 in 53. The rest are
follow-ups rather than one sweep -- ui-egui alone is 27 of those files and is the most contested
area in the repository. Some copies should stay: a test about a malformed cross-reference table
needs to write its own bytes.

* Issue #432: global Units preference (mm, cm, in, pt), defaulting to the system region
Preferences ▸ Documents and view ▸ Units sets the unit for page sizes
(Document Properties, Print), Header & Footer margins, the start of Set
Page Boxes and the Measure tool on pages without a viewport scale. On
first start it follows the system region: AppleMeasurementUnits on macOS,
Region ▸ Measurement system (iMeasure) on Windows, then LC_ALL /
LC_MEASUREMENT / LANG; inches for US, LR and MM, millimetres elsewhere.

* Issue #432: macOS falls back to AppleLocale when the measurement system was never set
AppleMeasurementUnits only exists in the global domain once someone changed
Measurement system in System Settings, and apps started from the Finder get no
LANG, so a German Mac with untouched settings landed on inches. The region of
AppleLocale (always present) decides next; AppleMeasurementUnits still wins.

* Issue #432: the Print dialog's PDF page size follows the Units preference
Main's new "PDF page: {w} × {h} in" label was always in inches. It now uses
the preferred unit like the sheet size next to it; each catalog keeps its
wording with the size in place of the inch values.

* M2: pages with /UserUnit are shown at their size in points, as in Acrobat
/UserUnit gives the size of a page's user-space unit in points; PdfCraft
ignored it everywhere except the measuring tools, so a /UserUnit 2 page
was shown, extracted, printed and edited at half its size, and the
measuring tools disagreed with the rest of the app.
The value is now read as Acrobat reads it (the page's own entry, a number
from 1 up, at most 75,000; anything else counts as 1) in two places:
- vendored hayro-syntax Page (patch 13): render_dimensions and
initial_transform give the page in points, so rendering, tiles,
PageInfo and the text layer follow; a page without it keeps exactly
the transform it had.
- pdfcraft-model Page: user_unit(), and display_size/view_matrix in
points, so print, header/footer, watermark, background, added content
and measuring agree with the screen. The measure crate drops its own
arithmetic. Added items record the /UserUnit they were written for;
items without the record (written before) read back converted.

* M2: an added item's recorded /UserUnit is clamped like the page's
An infinite or huge recorded /UserUnit made the scale factor 0 and collapsed the item.

instead of failing, closed polygons with a repeated vertex, printable unit
