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.

New crates/cad (L3): a hand-written ASCII DXF writer. Layers become DXF
layers (hidden: off, locked, non-printing: not plotted), straight paths
LWPOLYLINE (POLYLINE before R14), curves cubic SPLINEs through every
anchor, fills solid HATCHes (outlines in R12), strokes lines with a
lineweight and a linetype per dash pattern, type TEXT or glyph outlines,
placed images IMAGE entities linked to PNG or JPEG files. Units and
scale ($INSUNITS), scaled lineweights, 8/16/256 indexed or true colour

Alter Paths for Appearance, Outline Text.
document.export {format: dxf} and document.exportDxf; useArtboards
writes one drawing per artboard; selectedOnly (any export) writes the
selection in its layers. Export As lists DXF (then DXF Options,
ui.dxfOptionsDialog for agents, remembered between exports) and DWG
greyed out; document.formats lists DWG and PICT as unsupported with a
hint, and exporting or opening them answers with it.
