bflatastic 64891c1a2e Fix #234: EPS files from the reference app open
EPS files the reference app saves (its procsets in the prolog, a binary header with a TIFF
preview) now open as editable art instead of failing with "undefinedresource in Generic". When
their PostScript still can't be read, the palette preview they carry is placed with the usual
warning instead of the file being refused.

Root cause: five interpreter gaps and one preview format. The Generic and Category resource
categories didn't exist, so categories couldn't be made from Generic (now Category holds the
standard categories, defineresource in Category makes new ones, undefineresource is added);
clipsave/cliprestore were unknown (now a clip stack in the graphics state); systemdict's
languagelevel was the operator, not the integer 3; getinterval copied arrays and strings
instead of sharing their storage, so astore into a subarray was lost (arrays and strings are
now views into shared storage, and readstring/readline return the part they fill); and
resourceforall was unknown (now enumerates matching names with * ? \ templates). The preview
is an 8-bit palette TIFF with an alpha sample, which the image crate can't decode: a small
bounds-checked reader handles that layout (either byte order, any strips).

bflatastic 04fa49413c M8.16: Envelopes bend images, symbols, gradients, patterns and appearance; warps keep their frame
- 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.

bflatastic 42be928367 M8.16: Enveloped type exports distorted, run by run, everywhere
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).

theironchef 945dcbae1d Lint: as_chunks for constant chunk sizes, as clippy 1.99 asks
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.

bflatastic 49e8413ebe Fix #130: installed fonts are found by name whatever ran before
Opening, placing, pasting or importing a file, the font menus and MCP now find
the installed system fonts (Arial, Times New Roman...) in a fresh session, so a
file renders the same whatever happened earlier, and PDF import keeps the real
family names (Microsoft YaHei, not "Microsoft Ya Hei").

Root cause: FontDb only consulted the system font catalog, which stayed empty
until a CJK fallback or Character panel > Show System Fonts happened to scan
the font folders. Every lookup by family name (face, families, styles,
has_family) now waits for one cataloging scan per session: the app starts it
in the background, other processes run it on first use. The scan reads only
each file's table directory and name table (about 70 ms for 780 faces here,
instead of reading every font file whole), the catalog is indexed by family,
the family list is cached, and an installed style of a loaded family (a
bundled family also installed with more weights) loads when asked for.

bflatastic 0428e56342 M4.92: Print to a PostScript file
file.print {format: "postscript"} (the default for a .ps path) writes the
print job as Level 3 or 2 (level) PostScript instead of a PDF: DSC comments
with %%Pages the page count, one page per sheet with its paper size,
printer's marks in Registration, separations naming their ink (%%PlateColor)
with its halftone screen, a fixed flatness and film negatives. Transparency
is flattened first with flattenerPreset. The answer says which format was
written. In the app, a PostScript job is always saved, never sent to the
printer (the Print dialog's own options are unchanged).

The PDF print's layout is exposed as vectorcraft_pdf::plan (the PDF writer
uses it too); vectorcraft_eps::print draws its sheets with the EPS writer's
document walk, each sheet once however many copies print.

bflatastic 6752b22783 M4.91: EPS and PostScript files open and place
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.

bflatastic d01b2fbd8a M4.67: TIFF export in RGB, CMYK or grayscale, with LZW, either byte order and the profile
document.export {format: "tiff"} writes baseline TIFF through the raster
export path (resolution, background, anti-aliasing, artboard ranges):
colorModel rgb (transparency as unassociated alpha), cmyk (ink amounts,
CMYK colours keep their inks) or gray, lzw (weezl), byteOrder little (II)
or big (MM), embedIcc, and the resolution tags. Export As offers it with
the tiffOptions dialog; TIFF moves from read-only to read and write.

The TIFF writer is shared: EPS previews now use it (and its PackBits)
instead of their own copy, so eps depends on render (layers allow it).

bflatastic 4c4850e745 M4.76: EPS export (PostScript Level 2 and 3) with EPS Options, TIFF previews and the document embedded
New crates/eps (L3): a hand-written EPS writer. A DSC header with
%%BoundingBox and %%HiResBoundingBox (y up from the origin), %%LanguageLevel
and spot colours; paths filled and stroked with caps, joins, miter limits
and dashes (strokes a plain line can't draw as filled outlines, brushes as
their art), clipping groups, linear and radial gradients as smooth
shadings at Level 3 and stepped fills at Level 2 or with compatible
gradient printing, patterns as tiles, freeform gradients and placed images
as images (Flate with masked transparent pixels at Level 3, run-length at
Level 2), type as glyph outlines, spot colours as Separation spaces and
overprints when preserved; RGB written as CMYK on request. A TIFF preview
(1-bit or colour, transparent or opaque) behind the binary header, a PNG
thumbnail and the native document in comments (eps::native and
eps::thumbnail read them back for a later import).

document.export {format: eps} and document.exportEps: transparency is
flattened first with a flattener preset (built-in or saved) and options;
the visible art's bounds, or with useArtboards one file per artboard named
{stem}_{artboard}.eps. Export As lists EPS, then EPS Options
(ui.epsOptionsDialog for agents, remembered between exports).
