Each `Do` copied the page's `/XObject` dictionary, and each form its `/Resources`, `/Properties`,
`/Font` and `/ExtGState`, or the resources it was drawn with if it had none. So Office export of one
page took time in the square of what it drew: 31 s for 10,000 pictures, about 70 ms of it decoding, 30
s for 10,000 forms with no `/Resources`, and 16 minutes for one form with 100,000 keys in them drawn
50,000 times, in a test build.
`FormCall` keeps the form and `resource_dict` reads a dictionary where it is, with an object of its
own held. 10,000 pictures take about 0.15 s now, 10,000 forms 79 ms, and that form drawn 5,000 times 40 ms. The test holds to 10,000 pictures, not the 2,000 it could afford.
A `gs` reads a direct graphics state in place too, in the text walk and in `page_background`, and a
value of the wrong type isn't copied to find that out. A form that sets a font still reads the font each time it is drawn, as the fonts read
are kept only for that draw: 3.5 ms a draw for one of 100,000 widths.

Includes #4325#1952#4180#2529#4320#4805, preserving their original histories.
Keep paragraph alignment and hard/soft wrap metadata together; retain CCITT/downsampling/RGB ownership guards with bounded JBIG2 export and exact-copy symbol encoding.
Combined interaction regressions added. Validation pending.
wrap() already dropped the whole gap at a wrap point (#4199); rejoining it always guessed a single space back, so two or more typed spaces silently became one, and a Chinese/Japanese word split (which has no space of its own) could gain a spurious one. wrap() now records how many separator characters it consumed at each wrap (0 for a CJK split); the /PCSoft marker carries it as /N (a file saved before this, or by another writer, reads as 1); reflow_text and the mixed-style row editor insert exactly that many spaces back instead of assuming one.
wrap()'s own test for mixed exotic whitespace fed through it directly, bypassing the caller's CR/CRLF normalization, needed its expected value updated for #4199's keep-every-space design, landed on main after this branch's base.
Main brought #4178 (already on this branch), #4217 (edited text keeps
every space typed), #4266 (added text takes character spacing) and
#3546 (Save commits the open text boxes).
Conflicts:
- edit/added.rs: AddedText has both aligns and char_spacing. Lines are
measured with the spaced width (latin_width) and placed by their own
paragraph's alignment, with Tc set before them; both are read back.
- edit/text.rs: wrap keeps #4217's spacing and still returns each
line's row, so a row aligned on its own keeps its alignment; a
justified row stretches over its interior spaces only.
- ui-egui/content_ui.rs: the box keeps its per-paragraph layouter,
which now draws character spacing (spaced_job), with input_id() and
the per-document typing history.
- automation: aligns and char_spacing are both text-only options.
- Tests from both sides kept; #4178's two editor tests, present on both
sides, kept once, and mode_tab's doc comment put back.
The TextDraft literals from #3546 take selection and typing_from, and
an engine test's AddedText takes aligns. New test:
added_text_paragraphs_align_by_their_spaced_width, seen failing with
the unspaced width.
Edit text set a paragraph whose font lacks a typed character (an accent
missing from a subset) in a standard font, always under the resource
name PCEdHelv, whatever face it stood for. Rewriting a bold paragraph
after a regular one replaced PCEdHelv with Times-Bold, so every
paragraph set in the earlier stand-in turned bold, and the editor's
draft measurement saw those paragraphs change and grew its frame over
them.
The stand-in is now named after its face (PCEdTimesBold, ...), as the
line and region rewrites already name theirs.
Fixes#4280
Centring one highlighted line of a paragraph moves it out of the
paragraph's rows, so the next alignment of it saw a one-row paragraph
and aligned it in its own box: Left left it where it was, and since a
single row grows to the page's margin, each Centre moved it further
right. An alignment for a one-row paragraph is now laid out across the
column of text it sits in (the left edge the page's other text uses, to
the furthest right those rows reach), or its own box when no column
holds it.
Format text's alignment always re-aligned the whole paragraph or added
text box, and clicking it closed an added text box, losing the
selection, so one line couldn't be aligned. With text selected,
alignment now applies to the lines (text between line breaks) the
selection touches; with only the caret, to the whole box as before.
- Added text stores each line's alignment in its /PCAdded parameters
(/Aligns, null where a line follows /Align). A justified line's last
row is not stretched.
- An edited paragraph sends its rows' alignments with each rewrite
while it is open (BlockStyle::aligns), in both the single-style and
the styled-region rewrite.
- Both editors draw each line by its own alignment, and the alignment
buttons show the selected line's. An added text box stays open while
Format text is used, its style applied at once; clicks are judged by
where they were pressed, so a touch or pen tap on the panel doesn't
close either editor.
- Automation: `aligns` on page_add_text, content_update and text_edit.
rewrite_block clamps a requested paragraph width between the text's
size in user space (size * k) and the largest page PDF allows
(14 400 pt). f64::clamp panics when its minimum is the larger, so text
set above 14 400 pt crashed the app as soon as its paragraph was given
a width. The size comes from the file (`20000 Tf`, or `1 Tf` scaled up
by `Tm`) or from the request (the automation tools pass `size`
through).
The lower bound is now capped at 14 400 pt too, so such a paragraph
gets the widest width allowed. `f64::min` also turns a NaN size into
the cap.
Test: a 20000 pt Tf, a 1 pt Tf scaled 20000x by Tm, and a requested
size of 20000 pt each take a width of 200 without panicking (all three
panicked before).

A multi-line or multi-style draft is laid out by rewrite_styled_block, which broke rows only at \n: a CRLF left a stray CR before the break and a lone CR broke nothing. The CR of a CRLF is now skipped and a lone CR breaks the row, keeping the draft's character positions, and a draft whose only break is a lone CR takes the same path as one with \n.
Review follow-up for #3551: two ExtGStates at the same opacity are the same
Paint, so a dashed outline after a solid one joined its line and was
rewritten with the first run's selections. Ts tracks the effective dash
pattern and line cap, from d and J and from an ExtGState's /D and /LC, and
same_paint compares them as values for stroked text, so states with the
same settings under other names still continue a line. A dash array longer
than 32 entries, or with an operand that isn't a finite number, and a cap
outside 0-2 are ignored.

Review follow-up for #3551, rebased on the gs grouping of #3310:
- The styled rewrite draws each run in its own q/Q from the state where
the rewrite is drawn: a gs has no inverse, so one run's ExtGState stayed
in force for the runs after it. Two ExtGStates at the same opacity share
a paragraph (Paint), but either may set what Paint doesn't compare.
- The gs arm applies an ExtGState's /LW to the line width; paint_ops
restates the effective width after any replayed gs.
- A run whose visible Tr (or, for stroked text, stroke colour and width)
differs no longer joins the line before it, so a line is not rewritten
in its first run's state. Clipping and invisible modes still join, as
the #3447 refusal reads the whole line; gs changes are already kept
apart by Paint.

A rewritten paragraph is drawn before its text object and restated only the
font, spacing and fill. Anything the text object set before its first show was
lost: `1 Tr 1 0 0 RG 2 w` inside BT turned red outline text into filled black
text, and `/GS1 gs` inside BT made semi-transparent text opaque, even when the
text was unchanged.
The interpreter now tracks stroke colour, line width and the ExtGStates
selected (bounded to 32 distinct names), and the rewrite restates whatever
differs from the state in force where it is drawn. Styled runs restate it per
run, too.

Rewriting a paragraph in one style split its text at white space and
joined the words with one space, so a run of spaces, an indent or a
trailing space typed in the editor was saved as one space or none. The
text is now kept as typed (other white space becomes a space, and CR or
CRLF become line breaks), and the wrapper keeps each run of spaces,
dropping only the spaces where a row wraps.
A justified (stretched) row still drops its indent and the spaces after
its last word, as before, so word spacing reaches only the spaces
between its words; keeping an indent on a justified row is a possible
follow-up. Centred and right-aligned rows, and the editor's draft box,
are measured to the last word, and a paragraph at 0 Tz is not justified.
Fixes#4199Fixes#3797
TextLine::runs also says whether joining put a space before each run,
and covered_words uses it: a word shown in two runs with nothing
between them (`SE` `CRET`) is reported as one word, not `SE CRET`.
Runs with uncovered runs left out between them are still spaced.
The regression test writes its content streams on one line each.
Review on #4198 (CodeRabbit).
A text line joins runs painted on one baseline, and the audit reported
the line's whole text for a cover over part of it, including words
painted beside the cover that stay visible (`SECRETtail` for a cover
over `SECRET`).
TextLine now keeps each joined run's text with the end of its word
boxes (TextLine::runs), and the audit reports the runs whose words
the cover overlaps. A single run, a line reordered for reading
(right-to-left or visual-order Indic), or a cover that overlaps the
line's box but none of its words still reports the whole line.
Fixes#4164
The tests each branch appends to the audit, edit and organize test files are
kept side by side; prune.rs merges cleanly, with the form memo on top of the
budgeted page content.
The redaction audit read each page's text through text_lines, which walked
the whole page tree again for every page (quadratic in the page count) and
let /ActualText replace the glyphs, so an empty or substitute ActualText hid
covered text from the audit. Edit gains glyph_text_lines, which reads the
page dictionary it is given and ignores ActualText; the audit uses it.
Text extraction copies a ToUnicode destination for every glyph showing its
code, and the page's total text was not bounded, so a small page could expand
into gigabytes. One page's extraction (its forms included) stops with an error
past 16 MiB of text.
text_editor_fonts counted only the programs it kept against its 32 MiB
budget, so up to 128 aliases of one unusable program were each inflated
in full. Every decode now spends a shared 64 MiB allowance.
The editor's page readers decoded every /Contents entry and every form
entry with a fresh 1 GiB allowance, and the reading-order image
inventory added a record per image draw in every form entered, so a few
shared forms drawing each other produced millions of records. Content
streams and form entries are decoded against one per-page DecodeBudget
(content past it is an error, so no edit rewrites a page from part of
its content; forms past it are reported truncated), and an inventory
past 100,000 image draws is refused.
A text line joins compatible runs on one baseline, and the audit took
the line's last painting operator as its paint position. Text drawn
after a cover on the same baseline joined the covered words and moved
the line past the cover, so the covered words went unreported. The
audit now compares against the line's first painting operator: any
run painted before the cover is checked, and runs painted after it
in the same low-contrast color are unreadable on it too.
crates/edit/src/text.rs: interpret takes the page resources (#3310) with #3289's CachedFont cache and Result return; walk/enter return Result and use main's form budget; call sites pass resources and propagate with ?. TextLine and the text state keep both sides' fields (clips, gs; unreadable_mode, vertical, unreadable). The shown run keeps main's tracking: 0.0 with #3289's vertical advance and tm. replace_line checks ensure_editable before main's clipping-text refusal.
crates/edit/src/tests.rs: kept both sides' new tests.
crates/edit/src/text.rs: interpret takes the page resources (#3310) and the named property lists for /ActualText (main's #3301); every call site passes both. In BDC handling, #3310's layer push runs before main's property-list lookup; carry.layers is saved before positioned_tracking.
crates/edit/src/tests.rs: kept both sides' new tests.
ROADMAP.md: kept both sides' progress-log lines.
crates/edit/src/lib.rs: re-export list is the union (TextSession from #3942; BlockKey, block_overlapping from #2756).
