Before deciding to use the layers of an Illustrator file, the import
drew them again for each text object made from the file's text
document, to see whether the page draws it. When the layers differ from
the page by more than the check allows even with every such object
gone (taking one out only changes what is drawn in its box), the
layers aren't used whatever is taken out: that weighing is now
skipped.

Illustrator EPS and .ai type is made whole from the file's text
document, shown or hidden: point type, area type (a story in several
frames as threaded type that flows when the file opens) and type on a
path, with its fonts, size, leading, tracking, scaling, baseline shift,
fill and stroke colours (grey, RGB or CMYK), alignment, indents and
paragraph spacing. The page's drawing of that type, often in pieces, is
left out; where the text document can't say, type that shows still
comes from the page.

- Fit to Artwork Bounds fits the art exports draw: hidden objects and
layers, guides and template layers don't count, and the bounds stop at
a layer's clip.
- The comparison with the page catches an object one draws that the
other doesn't (pixels whose neighbours all differ, away from type), a
light colour against white, and, for an EPS whose page is its art's
box, art the layers print outside it.
- textAs: outlines opens a .ai whose type shows from its PDF part, which
has the outlines.
- document.open takes editingData: false to open an Illustrator EPS or
.ai as its page or PDF part only, for print pipelines.
Part of #637.

Each comparison of the layers' art with the page made a new renderer and
drew both again, so the page was drawn and every image decoded once per
text object weighed, plus once more for the final check. The page is now
drawn once, and the layers keep one renderer (with its decoded images)
across their draws. The page's images keep a renderer of their own, as
their keys can match the layers' without their pixels doing so.

Such a file's PDF part is a placeholder page, which was refused. When
the file carries editing data, it now opens from that alone: its
structure as a PDF-compatible file's, its point type made from the text
document, and type it can't make (area type, type on a path) left out
with a note that marks the import as lossy. Without editing data, or
with pages picked or layers off, the placeholder is refused as before;
damaged editing data says so.
The page-order note is no longer given when the page has no type.

The layers reader of the editing copy (operators translated into
PostScript for the interpreter, any file with RGB colours, gradients,
transparency or images falling back to its page) is replaced by a reader
of the whole structure (import/ai): layers and sublayers with their
options, groups, compound paths, clipping groups and layer clipping,
names, hidden and locked objects, RGB, CMYK, grey, named and spot
colours, gradients, transparency, fill rule, overprint, embedded images
with their alpha channel, guides and every artboard, and objects drawn
as their look when they have several fills or strokes, effects or a
brush. Containers: Zstandard, zlib or plain data in EPS and .ai.
The text placement, the comparison with the page and the overwrite guard
stay around it. The page's type takes its text object's place without a
group; the comparison is by lightness, on nothing, without layers that
don't print. Symbols, pattern fills, placed files and unknown operators
make the file come in as its page where they show, and are left out of
layers that don't.

- a story is read once however many text objects name it; the text objects, their pairs with the
page's type, the pieces of a line and a story's size are capped, and over a cap the layers aren't used
- the ASCII85 of the text document is bounded before it is decoded
- joining the pieces of lines that interleave no longer removes the wrong pieces
- a run length too large for the text saturates instead of overflowing
- a dictionary left open at the end of a layer, and layers nested deeper than are read, make the
file one that comes in as its page (they were silently dropped)
- a file whose editing data can't be decoded says so, and the notes about art that was too much or
too far away count as losses, so writing over the source asks first
- the private data of a .ai is inflated under a cap of its own (the PDF reader's decoder has none)
- the other writers (PDF, selection, office, print) ask before replacing a source that lost things,
and a recovered copy remembers that

Type turned to outlines leaves its text object in the file, which the app that
wrote it doesn't draw (it paints every shown text object on the page). A text
object made from the file's text document that shows on the page's area where the
page has no type, and without which the layers look no worse against the page, is
left out, with a note.

The pieces joined into one text kept the layout cached for the first piece, so the selection box covered only that piece.

- A PostScript font name's shortened style words (Md, Lt, Bd, XBd, Cn, It, ...)
weren't matched to installed faces, so AkzidenzGroteskPro-Md came in as
the condensed face. They are spelled out before the face is looked up.
- A line the page draws in pieces (around kerning) came in as several text
objects ("swe", "ep"); the pieces that add up to one line of the file's
text object now join into one, with the line's spaces between them.

Some files write a text object twice, once plainly and once as comments (and
others only as comments). Reading both made a second copy of the type, built from
the text document, over the page's own (wrong size and place). The commented copy
is now skipped when its story has a plain text object.

An Illustrator EPS is a flattened page plus, after %%EOF, an editing copy of
the document; a PDF-compatible .ai carries the same in its private data.
Importing only the page lost layer names, order, visibility, hidden layers
and hidden objects and hidden text.
- eps: read the editing copy (Zstandard %AI24_DataStream, older zlib
%AI9_DataStream) into layers, sublayers, groups, compound paths, clip
groups and hidden objects, run by the existing PostScript interpreter.
Falls back to the page, with a warning, when a shown layer uses an
operator that isn't read or the art differs from the page by over 5%.
- eps: read the text document (ate.rs) to place type on hidden layers and
objects; the page's type is matched to the file's text objects by
position (pieces of a line included) and kept with the nearest one when
none claims it. Area type and type on a path are left out with a note.
- pdf/engine: .ai files go through the same reader.
- engine/cli: a file whose import left things out isn't overwritten unless
asked (acknowledgeLoss, --replace-lossy).
- eps: font names re-encoded with a *<n> suffix resolve to their family.
- i18n: es/it/ru for the new import messages; ROADMAP updated.
Container and text-document formats were inferred from user-owned files; the
Adobe file format specification was not read.
