A legacy THSarabunPSK subset whose map gives a shifted alternate (glyphs
342-368) as the nominal mark, its nominal glyph dropped, shaped that
alternate wherever the nominal was needed, drawing the mark out of place.
The shaping copy now reaches an alternate only through its presentation
form, so text that needs the dropped nominal is refused instead.
A complete program of the source's family in another style, such as one
its descriptor marks bold, stopped the bundled Regular Thai outlines from
completing a Regular subset, and the text was then drawn in that bold
program. Count only a program in the source's style, as the subset
completion itself does.
The source shaper refused any Thai text in a program without GPOS mark
positioning, so a row of Thai digits failed although nothing in it is set
on a base. Require the positioning only for text with a vowel or tone
mark, or Sara Am.
The resource limit was checked before a form's resources were merged into
the page's, so one form could take the page past it and every later form
was then refused, even one whose resources were all the page's already.
Check the merged dictionary instead.
The first program of the face that could shape a span was chosen even when
its embedding permissions forbid embedding it, and the edit then failed
while a later program of the same face could have been used. Check that a
program may be embedded before choosing it.
A space that no subset of the face encodes was drawn as a quarter-em gap,
narrower than the text-space fallback the source font uses elsewhere.
Keep each subset's source space with it and use that for the gap.
Every resource name of a page's Thai subsets decoded and kept its own copy
of the font program, so many names of one large program could hold about
2 GiB for a single edit. Names of one font object now share its program,
the subsets of an edit are decoded within a shared 64 MiB allowance, and
an edit that needs more is refused with the reason, changing nothing.
A legacy subset can keep a cmap of its own that maps only Latin, so the
editor program returned it unchanged and an edit such as a consonant with a
tone mark failed although the subset keeps both outlines. Add the PDF's
verified Thai and alternate mappings to the editor-only cmap where the
program's own lacks them, keeping its existing mappings.
* M10: Correct recognized text keeps the window's tabs and toolbar and shows the page (ocr.correct-recognized-text)
Scan & OCR > Correct recognized text drew the OCR Verify screen before
the tab strip and the mode bar and returned, so it took the whole
window: the tabs, menus and toolbar went away (on macOS the traffic
lights landed on the PAGES caption). Its source pane drew only a
document the screen had recognized itself, so opened on a document
(already searchable or not) it was blank until a run.
The screen now takes the document area under the tab strip and the
mode bar; the command palette shows over it too. Before a run, and
after a review is accepted or rejected, the source pane shows the
document in front at the page it is on. Another mode or the Home tab
puts the screen away, as Exit does; the command brings it back with
its review as it was. A run now shows the first page it reads (the
current page for that scope) instead of page 1.

* M10: OCR Verify keeps its review when the document is closed and shows a page it read (ocr.correct-recognized-text)
- Closing a document whose OCR review is still open (File > Close, the tab's
Close, the snapshot bar's Close, Close all) brings the review forward with
a notice to accept or reject it first, instead of closing the document under it.
- After a run the source pane shows a page that was read, over one skipped for
its text; a run that read no pages keeps the page it was started on.
- PAGE shows the page's number over the document's page count.
- A cached preview of another document or page is dropped before rendering.
- The re-entry test checks a review and its correction survive another mode
and Correct recognized text.

* M10: OCR Verify holds Quit for an open review, lets a failed Accept be rejected, and survives a worker that cannot start (ocr.correct-recognized-text)
- Quit and closing the window bring a document under OCR review forward
with its review instead of exiting, as Close all does.
- Reject also throws away a reading whose Accept failed.
- A run or re-read whose worker thread cannot start leaves the screen
usable and an existing review as it was.
- A page preview that fails to render is not rendered again on every
repaint, only once the document changes.

* M10: the web build's leave warning asks while an OCR review is open (ocr.correct-recognized-text)
A browser reload or a closed tab cannot be held the way Close and Quit are,
so the beforeunload flag the web page reads now also counts an OCR review
that is not yet accepted or rejected, by the same check that holds Close all
and Quit.

* M10: an OCR review holds a deferred close, a run on another document, and the embedding page's leave warning (ocr.correct-recognized-text)
A close that waited for a save checks again for an OCR review started
meanwhile: the reviewed document stays open, and Close all and Quit stop.
Run OCR on another document while a review is held is refused with a
notice, so the review keeps its corrections. The embedding page's
`host_dirty` hears an open review as work at risk, as the reload warning
does.

A predictor whose parameters are an indirect object left its row tags in
the decoded font program and glyph map, so the Thai map repair, the glyph
codes and the shaper read the wrong bytes. Resolve the parameters as the
other font readers do, keeping the decode budgets.
Edit text queued Prepare grouped text for every page that came into view, after a full
preparation on a copy of the document on the UI thread to see whether it could. Scrolling cost
that work per page, marked the document changed, added undo steps and inlined shared forms
although nothing was edited.
Now nothing happens while pages are shown. A click (press and release, no drag) on grouped
artwork, routed to the picture by the page router as before, asks once whether that artwork
shows text preparation would open (text::forms::grouped_text_at, which reads the page without
copying or changing it). If it does, the page is prepared as one undoable step and the
paragraph at the point clicked opens for typing. A logo or a group preparation would refuse is
selected as before, with no message and no change. A drag still moves the selected group, and
while a paragraph is open or an edit is waiting the click selects as before. text_prepare is
unchanged.
The docs and the parity entry no longer say text is prepared on entering Edit text.
The repair reads the page's own fonts. It ran only after a group was expanded, so the same
damaged map on text that was never grouped kept reading wrong. Preparation now repairs it
whenever it finds it, recorded in the repair log as before, and PrepareText (text_prepare)
succeeds when it repaired a map even with nothing to expand. A repaired map no longer matches
the damage's fingerprint, so preparing again changes nothing.
Ungroup and text preparation now check the placement in one place, ungroup_ops, which is given
the page's operators and the Do's index:
- The form is looked up by the name the Do writes, byte for byte. Ungroup looked it up by the
picture's display name, a lossy UTF-8 copy, so a form named /F#FF was 'missing'.
- A Do with more than one operand is refused: the picture was read for its first, the renderer
draws its last.
- A Do inside BT…ET or an unfinished path is refused. Inline, the form's text objects would be
nested in the page's, and its clip would take in the page's path. Preparation already refused
these; Ungroup didn't.
A Q with no q before it restores nothing; the renderer ignores it. The check for translucency at
the Do took it as restoring the opaque default, so a transparency group drawn after /H gs Q was
inlined although it is drawn translucent.
A form with resources of its own and no /DefaultRGB (likewise Gray, CMYK) draws its device
colours as they are. Inline, the page's resources apply, and a /DefaultRGB there would remap
them (ISO 32000-2 §8.6.5.6). Only the form having an entry the page lacks was refused; now either
side having one the other doesn't share is.
text/forms/expand.rs was a drifted copy of ungroup.rs. It is gone: text preparation now opens each
placement with crate::ungroup, so Ungroup and preparation share one implementation.
What the copy added is now in ungroup.rs: a Refusal that says whether the form itself or only
this placement is the reason (intrinsic) and whether a rename alone was the problem (renaming),
the shows_text result, merges_without_renaming, refusals for unreadable /Resources and /Group
entries and arrays with a non-number, a cap on resource counts and q nesting, a total size for
pattern copies, and ending an unfinished path with the form. Ungroup's newer behaviour stays:
names are read from the operand the renderer uses, so a surplus operand is renamed correctly
rather than refused; default colour spaces are compared with the page's; and a group blending
in DeviceRGB on a page that names no blending space is drawn inline, as Ungroup does, rather
than refused as the copy did.
What a form draws is now read within one decode allowance shared with the form itself, so a
crafted group can no longer make one Ungroup decode 64 MiB for each of 1024 nested forms. A
group whose content can't be checked is refused; for a form without a group, blend modes inside
don't matter, and content that can't be checked only means preparation can't tell whether it
has text (shows_text is None), which it reports.
