craft-rtf: WordCraft's RTF reader and writer on craft-wordmodel and craft-flow (feature doc)
* Add craft-wordmodel: WordCraft's document model without its editing code
WordCraft's crates/doc (wordcraft-doc, at 07f97737) moved as it is, so the DOCX,
RTF, ODT and other text-format crates can read into and write from one model.
Module paths, type names and serde attributes are unchanged: an app that
re-exports the crate keeps its native file format.
Left in the app: range editing (edit.rs), IME text and equation editing. Not
model, and already in craft-libs: code pages (craft-rtf), the ZIP entry-count
check (craft-opc), the compound-file guard (craft-cfb). The paragraph walks
moved to walk.rs and the unit helpers of wordcraft-geom to geom.rs.
* craft-wordmodel: math_tree, the arguments of an equation node and a walk over its runs
The DOCX reader and writer walk an equation's runs. The walk and the child
accessors it uses were in WordCraft's equation editor (math_edit.rs), which
stays in the app; they are structure, not editing.
* craft-wordmodel: keep the document operations (edit.rs) with the model
The DOCX and RTF readers use them: alternative-format chunks are merged into
a document with adopt_blocks, and a reader formats ranges with format_range
and inserts objects. They operate on the document, not on a view, so they
belong beside it. The tests that drove them come back with them; the
paragraph walks stay in walk.rs and edit re-exports them.
base64 0.23, as WordCraft and craft-offcrypto use.
* Add craft-flow: the flow model the text formats map to, on craft-wordmodel
WordCraft's crates/formats/src/model (07f97737) moved as it is: Flow,
FBlock, Para, Inline, Fmt, tables and cells, pictures, to_doc and
from_doc, picture sniffing, colours, base64 and the Dropped report. Only
the paths changed (wordcraft_doc is craft_wordmodel); the report helpers
are public so the format crates can call them; the image re-encoding
helper stays with WordCraft's RTF writer.
* wip: WordCraft's RTF interpreter, as it is
* Take main's side of files outside craft-rtf
* craft-rtf: WordCraft's RTF reader and writer as they are at wordcraft 07f97737
crates/formats/src/rtf.rs and crates/formats/src/rtf/, unchanged and not yet
compiled (no module declares them), so the next commit shows only what the
move changes.
* craft-rtf: WordCraft's RTF reader and writer as craft_rtf::doc (feature doc)
On craft-flow and craft-wordmodel, with this crate's code pages
(craft-codepage), dates and escaping in place of WordCraft's copies, and
craft-metafile's metafile sniffing. A picture in a format RTF cannot carry is
re-encoded as PNG with a bounded decode (100 megapixels, 512 MiB), as
WordCraft's picture decoder bounded it.
The 76 tests moved with it.
craft-rtf and craft-dxf each carried tables for DOS 437, 737, 850, 852 and
857 (and craft-rtf one for 866). They are now one set in craft-codepage,
which takes craft-rtf's codepage module (Windows and Mac tables, OEM glyphs,
font charsets) and craft-dxf's DOS tables. craft_rtf::codepage re-exports it
unchanged; craft-dxf keeps its $DWGCODEPAGE names and Decoder and looks the
DOS tables up there.
Every byte of every code page either crate decodes is unchanged: the
public decoders of both crates were dumped over all 256 bytes of each page
(and the East Asian pairs) before and after, and the dumps are identical.
craft-mime now reads the DOS pages by their IANA names (IBM437, cp850,
ibm-852, 857...), which it read as UTF-8 before.
The outlook feature adds MailCraft's reader of PidTagRtfCompressed
([MS-OXRTFCP]) and of the text and encapsulated HTML ([MS-OXRTFEX]) of the
RTF inside, from crates/pst/src/rtf.rs at a44a450. Font charsets use this
crate's charset_code_page table; code pages are decoded by craft-mime.

* Add craft-rtf: RTF tokenizer, text decoding, and a reader and writer for a small model
The tokenizing rules, code pages, multibyte decoding, dates and escaping come
from WordCraft's RTF reader and writer. The model (paragraphs with outline
level and indent, character formatting, tables) covers what DesignCraft's text
import, DeckCraft's outline import and export and PdfCraft's export use.
An unpaired UTF-16 surrogate in \u reads as U+FFFD and a high surrogate pairs
only with the very next \u, as storytold/wordcraft#6105 describes for Word.
* craft-rtf: a symbol font's bytes are its own codes
A font with \fcharset2 (Symbol, Wingdings) has no letters: a byte from 0x80
reads as U+F000 + the byte instead of a letter of the document's code page.
The symbol page applies to body text only, a symbol default font's page does
not apply to text in a font chosen with \f, \plain makes the default font's
page current again, and a code page an entry names with \cpg is kept.
Ported from storytold/wordcraft#6014.
* craft-rtf: alignment, indents, spacing, superscript and subscript; NUL is not text
The model and both directions gain what DesignCraft's RTF export writes:
\ql \qc \qr \qj, \ri, \fi, \sb, \sa, \super, \sub, \nosupersub.
A \u0 or \'00 no longer puts a NUL into the text.
