Each leaf page gets its own copy of every attribute it inherits, so a
large direct /Resources on the root of a page tree with thousands of
leaves was copied thousands of times: a compressed file of a few
kilobytes could need tens of gigabytes. The walk weighs each inherited
value once where it is declared and charges every copy to a 1 GiB
budget; past it the walk is cut off, as an over-large tree already is.
Page::rotation rounded a /Rotate that isn't a multiple of 90 down to a
quarter turn (135 became 90), while the renderer draws such a page
upright. Display size and the display-to-user-space matrix (header and
footer, watermarks, measuring, printing, image signatures) then
disagreed with the page on screen. ISO 32000-2 §7.7.3.3 requires a
multiple of 90; read any other value as 0, as the renderer does.
Page import and image stamps, which read /Rotate themselves, already
treat such a value as 0. Test: rotate_off_a_quarter_turn_counts_as_upright
(/Rotate 135, 30, -45, 359).
* 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.

* Stamps and added images follow a JPEG's EXIF orientation (part of #434)
Phones store a portrait photo as landscape pixels plus an EXIF
Orientation tag. A JPEG went into the PDF as it was (DCTDecode), and PDF
image XObjects have no such tag, so a photo used as a custom stamp, an
added or replaced image, a watermark or background, or a button image
showed up turned 90 degrees.
Before these images are embedded, a JPEG whose Orientation is not 1 is
decoded, turned the way the tag says and re-encoded (quality 92). Its
JFIF resolution is kept, swapped for quarter turns, so the natural size
on the page stays right. Other images, JPEGs without the tag, JPEGs that
fail to decode and photos over 64 megapixels are embedded unchanged, as
before. Fill & Sign image signatures already applied the tag.
* Image signatures stay upright and anchored on rotated pages (part of #434)
On a page with /Rotate 90, 180 or 270 an image signature turned with the
page, because its picture was drawn along user-space axes while the click
or the "at" argument is a displayed point. It was also anchored at the
wrong point: its left edge and vertical centre were taken in user space,
so on a 90 degree page the image centre ended up elsewhere.
The signature's appearance now carries the counter-rotation as its form
/Matrix, which viewers fit to /Rect, so the picture reads upright as
displayed. The page's rotation is kept in /PCPictureRotate, so restyling
regenerates the same matrix and moving and resizing keep it. The box of the
signature runs along the displayed axes, so its left edge and vertical
centre are where they were asked for. The page view matrix in
pdfcraft-model is split out as view_matrix_for.
The Fill & Sign preview and the live move/resize preview draw the picture
the way the appearance does, and the resize handles keep the image's
proportions as displayed. comment_image_preview reports image_rotation,
how far the image is shown turned (0 for one placed upright).
Custom image stamps are left to #473.
* Use is_multiple_of for the quarter-turn checks (clippy) (#434)
* Probe the pointer preview away from egui_kittest's drawn cursor (#434)
The kittest render paints a mouse cursor (a 16 px triangle with a black outline) at the
hover point, so the 2 pt probe beside the pointer landed on its outline when zoom and view
rotation made 2 pt only a pixel or two. Put the stroke's block at the picture's right end and
probe there and at its far margin instead.
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).

annot, compare, content, cos, export, geom, model, ocr, preflight, print and redact have no
production `unwrap`/`expect`/`panic!`/`unreachable!`/`todo!`/`unimplemented!`. The attribute
keeps it that way.
