The text document reader set a type stroke's paint and weight but never
its cap, join or miter limit, so every stroked text object imported from
a .ai or EPS editing copy drew with a miter join at a limit of 10. Type
the file strokes with round joins, or with a miter limit of 4 or less,
drew long spikes at its sharp corners.
Keys 61, 62 and 64 of a run's character attributes (the run, its
character style, then the document defaults) are now read as the
stroke's cap (0 butt, 1 round, 2 projecting), join (0 miter, 1 round,
2 bevel) and miter limit, as PostScript numbers caps and joins. In the
users' files the page strokes type with exactly these settings. Other
values keep the defaults, a miter limit is capped at 500, and type
without a stroke keeps the defaults.
- ate.rs: Style reads the three keys and char_style passes them on,
with a unit test over defaults, character styles, run overrides,
hostile values and unstroked type.
- tests_native.rs: an imported story with round, bevel, default and
unstroked runs.
- docs/file-format-parity.md: revision row, status line, one line on
the mapping.

Two installed versions of one font are two fonts of the set, so each
keeps its own /5. The generated variable test font now has a version
(name ID 5), and the test checks each variable record writes it.

A variable font's CoolTypeFont record in the text document now carries
/4 (its design vector, one 16.16 value per fvar axis) and /5 (its
version string), and the font set keys on name plus design vector, so a
named instance or a run's own axis setting no longer opens at the
font's default instance. Static fonts are unchanged.

The put-back after a failed page check replaces each live envelope with
its drawn art in one go, which fails as a whole when one envelope lies in
another's art: only the outermost are put back now. A live envelope of
type removes its hidden type only once it has found the drawn art it
replaces. The file format docs lose a revision row left twice by a rebase.

A variable library binds the text object a slot of the envelope's
contents became, which stays hidden beside the drawn art. Once the
envelope opened live that hidden text object went, and its type in the
envelope has an id of its own, so a visibility binding was dropped and
counted as one that wasn't made. A slot bound to a text variable
already kept the drawn art; one bound to a visibility variable does
too now, with the note, so the binding is kept.
Carrying the binding over to the type in the live envelope would bind
an object inside an envelope's contents, which nothing in the import,
the data sets or the .ai writer is known to handle, so it is left for
later.

An envelope of type opens live only where the layers with it draw as
the page. Two ways of using layers that don't left it live all the
same: the editing data trusted (they come from it with a note), and
the objects that draw differently coming in as the page's art. In both
the envelope now keeps its drawn art and its type, hidden, with the
note, as where its drawn art is put back. A .ai whose layers would
open alone, without its PDF part, then opens alone again, as it did
before envelopes of type could open live, rather than compared with
the page.
The type put back no longer carries the mark of type made from the
text document in its name.

The comparison with the page counts the area of each text object that
shows as type, which it holds to less (type laid out again from the
file's text can sit a little apart from the page's). It took the text
object in a live envelope's contents for such type, at its own unbent
box, so most of what an envelope of type draws went unweighed: one
opened live where the page draws other art there, with only a note
that the type differs. The envelope draws its type bent, as art, and
is now weighed as such, as the drawn art it takes the place of is.
Part of #3179.

An envelope whose contents hold type kept its drawn art, with the type
hidden, because the type is laid out from the text document only after
the layers are read. It now waits for that, as warped type does: once
its text slots hold their type, the envelope is made of that type and
drawn by VectorCraft's own rule, and where it draws as the drawn art the
file saves (the same check and budget as other envelopes) it takes the
drawn art's place, with the type visible and editable in Edit Contents.
The hidden copy of the type goes.
As other live envelopes are, it is held to the page: when the layers
with it don't draw as the page, its drawn art and hidden type are put
back. A .ai whose layers would open alone, without its PDF part, now
waits on the PDF part when an envelope of type is in them; where none
opens live, the layers open alone as before. Layers built without a page
leave envelopes of type their drawn art.
Elsewhere it keeps its drawn art and hidden type, with the note: type in
a font that isn't available, a slot without made type (threaded, bound
to a text variable, a wrap object, type a look draws), an envelope that
doesn't read, no check left, or one that draws differently. Envelopes in
a symbol's or a pattern's art keep their drawn art.
Part of #3179.

The check that keeps a live envelope or warped type only where it draws
as the art saved with it renders each on its own, over nothing, and
compared the pixels as seen on white. White art over nothing looks like
nothing on white, so white contents that drew somewhere else passed and
opened live in the wrong place.
Pixels now also differ when they look different seen on black, so such
art keeps its saved art, as colored art does. Opaque colored art is
compared as before.

A text slot the text document gives nothing is left out, with a note of
its own, so the note for type in an envelope no longer says the type is
kept hidden.

An envelope of type keeps its drawn art with its type hidden, but nothing
in the import notes said so, while the other envelopes that keep their
drawn art do. Opening such a file now notes that the type in an envelope
comes in as the envelope's drawn art, not as editable type, and that the
type is kept hidden. The type is still not editable in the envelope.

An image whose color space XC sets to one ink (n [c m y k /DeviceCMYK
(name) /Separation] XC) opened as a gray RGB image: its samples, the ink's
tints (255 at 100 %), were read as gray levels, so the tints drew inverted
and the ink was lost.
It now opens as a grayscale image of the tints, black at 100 %, colorized
by the ink at 100 %: its spot swatch, a process plate's CMYK color, or
Registration. Its alpha channel becomes its opacity mask, a reduced large
image's too (a colorized image reduced to fit the limits no longer keeps
its alpha in its pixels). 8-bit and 1-bit samples, binary or in hex
comment lines. A device space and the ink None change nothing.

The warning #6326 added listed the families `set_text` met while the
page ran. An Illustrator EPS can be rebuilt from its editing copy,
whose type may be in other fonts than the page's, and `stringwidth` and
`charpath` reach `set_text` without adding any type. The families are
now taken from the text objects of the document the import gives (its
layers and its symbols), once each, in the order the type comes,
whichever path built it.
Type set in a family that isn't available keeps its name and shows in
the fallback font, as in PDF import, but EPS import said nothing. It
now notes each such family once, in the order its type comes (at most
64), and ends with PDF import's warning: "fonts that aren't available
show in the fallback font until they are: <families>".
Tests that set type in fonts the test machine may lack (Helvetica,
Ryumin, made-up names) check the program's warnings without that note,
since which fonts are installed depends on the machine.
When the page's type is matched with the text objects, page words are also
split at private-use characters (from uniXXXX ligature glyph names such as
/uniE028 for a "ti" ligature) and each piece is matched as its own word, so
"Quality" set with that ligature matches its text object and the layers are
read without a false note.
A CMap name of the public Unicode CMap form (UniJIS-UCS2-H, UniGB-UTF16-H
and similar) is understood without being defined in the file, so type in a
CIDFont the file only names decodes to its Unicode characters and is set as
live type.
bfchar and bfrange mappings are kept in the CMap and carried over by
usecmap. A code mapped to a character code draws that code in the base font
usefont named; a code mapped to a glyph name draws that glyph.
Each CID-keyed font in a FontSet's CFF data is defined as a CIDFont named by
the CFF Name INDEX, with its glyphs found by CID through the charset and
FDSelect, so a composefont over it draws its type.
Between each two characters the kshow procedure runs with the two codes and
the current point after the first, in any font, not only Type 3 fonts. Where
it moves the current point the next character follows, kept as tracking.
An embedded Type 1 font's eexec part is decrypted and its charstrings read,
so its glyphs and widths are used instead of the installed or fallback
font's. Codes are decoded through the font's Encoding, so fonts that place
glyphs at low codes no longer lose their type.
Adds composefont, the CIDInit and FontSetInit procedure sets and the CMap
operators, so EPS with CID-keyed fonts (as pdftops -level3 writes) opens.
Type 0 fonts with FMapType 9 decode their codes through the CMap's codespace
ranges and CID mappings, and the Identity CMaps are predefined.
A plain Type 42 font now maps each code to its character through its glyph
names, or through the glyph its CharStrings give it in the font's own
character map or post names, instead of reading the code as Latin-1. The
font's own widths move the current point, charpath outlines its glyphs, and
the show operators' spacing and the embedded widths are kept on live type as
tracking. Type shown under nulldevice no longer appears.
Only a Stroke Style filter's widths written as one centered array come in as the drawn look. A Stroke Offset stroke and widths written for each side stay live with their profile.
