Legacy PostScript .ai files (Illustrator 3-8, and their EPS) open through
the EPS interpreter, which only recorded what was drawn: every group came
in flattened. In a file in Illustrator's format (its %AI comments, or
Illustrator named as the creator) the `u` ... `U` it writes at the top
level now open and close groups, whatever its prolog defines them as, so
groups come in nested as they were, between and inside clipping groups.
clipnest's Clip carries an optional region: without one it is a plain
group, nested in the same chain as the clips (ids given in opening order,
so a chain of clips and groups sorts by id).
Clips nested without end used to nest clipping groups past the stack
(a stack overflow in EPS and EMF/WMF import): clips and groups now nest
at most 128 deep with a warning, and each object's chain counts against
the EPS reader's drawing budget.
PDF-compatible .ai (Illustrator 9+) can't get the same: its PDF content
draws each object on its own and doesn't mark plain groups (only layers,
clipping groups and groups with opacity, blending or a mask, which
already come back); the groups live only in the private data, which is
out of scope. Documented in ROADMAP and docs/mcp.md.

- Images distort as a raster mesh warp: cut by Fidelity into triangles,
each a clipped image under the affine map of its corners (pieces overlap
slightly, no seams; the renderer paints them without clip layers; SVG
writes the pixels once and <use>s them).
- Symbol instances distort as their symbol's art (the renderer's cache
follows edits to the symbol).
- Distort Appearance bakes strokes (filled outlines) and geometry effects
before bending; Distort Linear Gradients bends linear gradients; Distort
Pattern Fills bends the tiles. Opacity masks of the content bend too.
- Bug fix: a rotated, sheared or reflected warp envelope re-warped along
the page axes. Envelopes now keep their own frame (append-only model
field), so the warp turns with the art; move and scale keep it square.
- Live evaluation shares one set of hooks (vectorcraft_doc::live::Hooks,
vectorcraft_effects::{expand_live, expanded_live_group,
expand_live_deep}) between the canvas, Expand and every exporter.

Every exporter (SVG, PDF, EPS, EMF/WMF, DXF) evaluated live objects with no
text outliner, so type inside an envelope was written undistorted. They now
share vectorcraft_effects::expand_live_deep, which outlines type per run in
each run's paint, as the canvas now does too (it used the first run's paint
for the whole line).

Rust 1.99's clippy adds chunks_exact_to_as_chunks, and cargo clippy
--workspace --all-targets -D warnings (cargo xtask ci) failed on its eight
hits in metafile, pdf and eps. as_chunks gives fixed-size arrays, so the
loops read the same bytes without indexing into slices, and encrypt's
CBC loop takes the remainder from as_chunks instead of the iterator.
as_chunks is stable since 1.88.

document.open and file.place read .eps files and PostScript by any name
(PostScript .ai opens as artwork, .ait as a new untitled document). An EPS
file VectorCraft wrote restores the document it carries (restored: true);
other files run through a small clean-room PostScript interpreter (paths,
colours and spot inks, gsave/grestore, concat, line state, bind def,
procedures, loops and dictionaries, clips, shadings, images through the
decoding filters, type as point type), and fall back to their TIFF preview
with a warning when the program can't be read. Operation, nesting, memory
and path budgets keep hostile files from hanging or exhausting memory.
The clipping-group nesting the metafile reader used moves to
vectorcraft_doc::clipnest, shared by both readers.

crates/metafile import: EMF and WMF (placeable or not) records play on a
small device-context model (objects numbered as GDI does, saved DCs, world
transforms and mapping modes, path brackets, the current position) into one
artboard (the picture's frame) and one layer: paths with fills and strokes
(pens with caps, joins, dashes), clipping groups for clips, images from DIBs
(StretchDIBits, BitBlt, StretchBlt, AlphaBlend, StretchDIB, DIBBitBlt) and
point type in the font the file names. Lines drawn one after another join
into one path; a clip around the whole picture is dropped; objects far
outside it are left out; unknown records are skipped with one warning.
document.open and file.place read .emf and .wmf through the shared loader
(Open and Place filters list them). clipboard.importEmf loads a picture into
the clipboard, and Paste takes image/emf from a system clipboard service
ahead of text and bitmaps. The import fuzzer covers mutated and random-record
metafiles opened, placed and pasted.

New crates/metafile (L3, pure Rust): hand-written EMF and WMF writers over
one shared document walk. EMF keeps Bezier paths, solid brushes, geometric
pens (width, caps, joins, miter limit, user-style dashes), clipping masks as
path clips, images (StretchDIBits, or AlphaBlend with transparency) placed by
a world transform, type as outlines; gradients become images clipped to their
shape and pattern fills their tiles clipped to it. The header's frame is the
artboard in 0.01 mm on a 100 px/mm reference device. WMF flattens curves into
polygons in 16-bit units behind a placeable header (with its checksum),
numbers objects as players do, and reports what it leaves out (clipping,
transparency, gradients, rotated images).
document.export {format: emf|wmf} (and serialize, export) writes one artboard,
or one file per artboard with useArtboards (false: the art's bounds); raster
effects are rendered to images first, as for PDF. Export As lists EMF and WMF.
