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
(420), transparency (440), Preserve Appearance / Maximize Editability,
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.

file.place {path | name+dataBase64, link, template, replace, at, rect, page, crop} places a
file as one undo step without touching the clipboard. Raster images come in at 100% of the
resolution their file declares (PNG pHYs, JFIF/EXIF, TIFF, BMP; 72 ppi otherwise), linked to
their path by default; SVG becomes one group with its embedded images; a PDF/.ai page or a
native document's artboard becomes one clipped group. The images, symbols, patterns and
swatches the art uses join the document (renamed on conflict). Replace keeps the replaced
object's stacking place and transform; Template puts the art on a new locked template layer
below the current one. file.place.info and image.info report size, ppi and colour mode.
File > Place picks a file and opens the Place dialog (Link, Template, Replace); the web picks
through the inbox. The Control bar shows Linked File/Embedded, the file name, colour mode and
ppi of the selected image.

svgz is a writable format with the SVG options (document.export,
serialize, save, Export for Screens): exactly the SVG export, gzipped.
SVGZ is recognised by its extension or the gzip magic bytes and opens,
places and pastes like SVG (clipboard.importSvg takes dataBase64 of SVG
or SVGZ); Export As SVG or Save As to a .svgz name writes it
compressed. Gzip lives in the svg crate (pure-Rust flate2, builds for
wasm) and unpacking stops at 512 MB.
