The nine OFL faces in `assets/fonts` are compiled into every build of
vectorcraft-text: 3.4 MB of the binary, about 1.6 MB of a gzipped wasm.
An embedder that loads every font at run time with `FontDb::add_font`
(a web app serving its own font catalogue, say) ships them twice and
can't turn them off.
- vectorcraft-text: `bundled-fonts`, a default feature, holds the
`include_bytes!` list. Off, a database starts without them (craft-fonts
and system fonts are unaffected) and text has no glyphs until a font
is added, as when the bundled fonts fail to parse.
- vectorcraft-engine: a `bundled-fonts` default feature forwards to it,
so the apps and any embedder using the engine keep the fonts unless
they build it with `default-features = false`.
- The workspace declares vectorcraft-text without default features, so
no library crate turns the fonts back on. The tests of cad, metafile
and tools, which lay type out, ask for the feature in their
dev-dependencies; the other crates' tests get it through testkit.
`cargo test --workspace` builds with the fonts, as before. A new
integration test, `without_bundled_fonts`, covers the configuration
without them (`cargo test -p vectorcraft-text --no-default-features
--test without_bundled_fonts`): the database starts without them, text
in no font lays out with no glyphs, and a font added later is used and
is the fallback for families the database lacks.

These scripts don't separate words with spaces, and lines only broke at
spaces, hyphens and CJK characters, so a Thai paragraph in area type ran
on to the next space (or was cut wherever it overflowed). Each
paragraph's glyphs now carry the word ends ICU4X's line segmenter finds
in text of those scripts (its dictionaries on the desktop, its far
smaller LSTM models on the web), and a line may break after them as
after a space. Other text keeps its own breaks, and clusters (a
consonant with its vowel and tone marks) still never split.

The Type tool's Left and Right arrows and Delete moved one code point at
a time, so the caret could stop between a Thai consonant and its vowel
or tone marks (or inside an accented letter or emoji sequence), where
typing or deleting splits the cluster. They now step over extended
grapheme clusters. Backspace still takes back one character at a time,
as Thai typists expect for a mistyped tone mark.

The scan read only the platform's font folders, once per session (or on
Character panel menu > Refresh Font List). Fonts Windows registers outside
its font folders (installed as shortcuts, or by programs into their own
folders) never listed, nor did fonts installed while the app was open.
- Windows: the font files registered under the local machine's and the
user's Fonts registry keys outside the scanned folders are scanned too
(windows-registry, the windows-rs project's safe registry API).
- Linux/BSD: the XDG data folders' fonts (XDG_DATA_HOME, XDG_DATA_DIRS:
Flatpak, Snap, NixOS, Guix) and a Flatpak sandbox's host fonts
(/run/host/fonts, local-fonts, user-fonts); macOS: /Network/Library/Fonts.
- The global database looks the platform's paths up again at each scan,
and a scan's roots may be font files as well as folders.
- FontDb::installed_fonts_changed compares the folders the last scan read
(their modification times, and the paths it started from); the app
checks it when its window comes back to the front and rescans
(text.rescanFonts) only when fonts were installed or removed meanwhile.

- Unicode bidi (unicode-bidi, unicode-script, unicode-general-category):
each paragraph's direction from its first strong character, Hebrew and
Arabic shaped right to left, embedded Latin and numbers keep theirs,
lines wrapped in logical order and reordered per line by whole
clusters; source text, undo and style ranges stay logical.
- Caret, hit testing, selection and the arrow keys follow the visual
order.
- New text aligns automatically: right-to-left paragraphs right, others
left (Justify::Auto, text.setStyle {justify: "auto"}); the Paragraph
panel highlights the resolved alignment and has an Automatic alignment
toggle. Explicit alignments, and older documents', are kept.
- SVG export outlines bidirectional text (with a warning) until it can
be written as directional live text.
The font database made one style per font file, so a variable font
such as Figtree[wght].ttf listed only its default instance (Light).
Faces now also yield their fvar named instances, each a style of the
family named by its subfamily name (the default instance is the face
itself; unnamed or duplicate instances are left out; axes and
instances read are capped). The system font scan reads the fvar table
beside the name table, so installed instances are listed before the
file is loaded and found by name and by PostScript name.
An instance face carries its axis settings: skrifa draws its outlines
and reads its metrics and advances at that location, harfrust shapes
with a ShaperInstance, so layout, the canvas, Create Outlines and hit
testing all use the instance. PDF export embeds it through krilla's
Font::new_variable, SVG @font-face through subsetter's
subset_with_variations: both write a static font of that instance.
Tests build a small variable font in code (test_fonts, via
write-fonts; no font file is committed) and check listing, resolving,
glyphs and advances, PDF and SVG export and damaged fvar/gvar tables;
Bahnschrift and Segoe UI Variable are checked where installed.

SVG export writes UTF-8, UTF-16 (big-endian with a byte order mark) or
ISO 8859-1 (other characters as character references) and SVG/SVGZ
open in any of them. The Tiny 1.2 profile (simplified) writes
presentation attributes only and leaves out filters, masks, blend
modes and symbols with warnings. embedFonts embeds the fonts type uses
as @font-face subsets of the characters used, honouring the fonts'
fsType (whole when subsetting is forbidden, left out when embedding
is). New options: encoding, profile, embedFonts (SVG Options dialog,
document.formats); document.serialize also returns dataBase64 for
non-UTF-8 files.
