An envelope is written on `%_` lines as a group holding the mesh that shapes
it, with the distortion (`AIDeformStyle`, `DeformValue`) in the group's
dictionary; the distorted art the PDF part draws follows on plain lines. The
reader kept that group, so the mesh drew as a grey gradient mesh behind the
art. A group on `%_` lines that holds only meshes and carries a distortion is
now dropped; a mesh with no distortion is still art.

A .ai or EPS opened from its editing data lost the opacity and blend
mode of its text objects. text_slot made the slot without the graphics
state's opacity and blend mode, which paths, meshes and images take, so
an Xy before a text object was lost. An Xy after it reached the slot,
but fill_slots then put type made from the text document in the slot's
place with only its visibility and name, and style_marker dropped the
transparency that a text object with an appearance carries on its look.
text_slot now takes the state's opacity and blend mode. fill_slots
gives made type the slot's opacity, blend mode, isolation and knockout.
The page's type gets them too, in place of its own transparency when
that is none, the slot's, or the slot's combined with that of the
objects around it; otherwise the page's type and the strokes around it
keep their own (a fill's, for example). When the type has transparency
and comes with other art (the strokes the page draws around it, or page
type that goes with it), a group of them takes the transparency. A text
object with an appearance takes the transparency from its look; where
the look draws more than the type and has transparency, the look and
the type go into a group that has it, and that group is not taken as
the look of a later object. The import fuzz's .ai tokens now include a
commented text object, 1 /FreeUndo , and a group's state marker
(6 () XW).

Shift pressed while dragging a segment had no effect on the curve:
Direct Selection's curved-segment and spine-segment drags, the Anchor
Point tool and the Pen with Alt sent the pointer offset alone, and the
segment bent freely. The reference app keeps the handles in the
perpendicular direction and of equal length while Shift is held.
path.reshapeSegment and object.blend.spine.reshapeSegment take
perpendicular (default false, which keeps today's behavior). With it,
both of the segment's handles stand at right angles to the line between
its anchors, on the same side and at the same length, and the point at
t lies as far from that line as the moved point does. A smooth anchor
at either end stays smooth, as it does in a drag without perpendicular,
and a segment whose anchors coincide bends as it does without
perpendicular. With Direct Selection, Shift pressed once a curved
segment's drag has started sends perpendicular; Shift held at the press
still toggles the path's selection, as before. Direct Selection's
spine-segment drag and the Anchor Point tool's segment drag send Shift
as perpendicular too, so the Pen with Alt does as well. A straight
segment dragged with Direct Selection already moves at 45° steps with
Shift.

Shift+Enter in a panel or Control bar field ended its editing, as Enter
does. The reference app's default keyboard shortcuts list "Apply value
and keep text box active" under Use panels and "Apply a value and keep
focus in edit field" under Transform panel, both Shift+Enter on Windows
and Shift+Return on macOS.
- A focused single-line field of the shared widgets (num_field,
mixed_field, plain_field, range_field, spin_field, spin_field_auto,
spin_plain, text_field, exact_text_field, opt_field and hex_field)
takes Shift+Enter before its text box reads it, applies the text as
Enter does and keeps the focus. In the next frame it shows the value
as it now is, all selected, so typing replaces it.
- A text box of several lines keeps Shift+Enter as a line break.
- While a dialog is open, Shift+Enter applies the field's value and
confirms the dialog, as before. The app sets widgets::set_dialog_open
at the start of each frame.

The Paragraph panel menu's Reset Panel turned Hyphenate off but left
the Hyphenation options: Words Longer Than, After First, Before Last,
Hyphen Limit, Hyphenation Zone and Hyphenate Capitalized Words. A
paragraph kept its custom hyphenation limits after a reset.
Reset Panel now also sets those six options to the values of
HyphenationOptions::default(), in the same text.setFormat call. The
reset paragraphs then save no hyphenation options.
Smart Blur's Edge Only and Overlay Edge modes marked a pixel when one
of its four nearest pixels differed from it by more than Threshold,
and Radius changed only the blur. The reference app's documentation
says that Radius sets the size of the area searched for dissimilar
pixels.
A pixel is now on an edge when one of the pixels the search reads
within Radius differs from it by more than Threshold and its
channels, alpha included, add up to at least that pixel's. The search
picks its neighbors as the Normal blur does, over the whole pixels of
Radius and within it, and always reads the four nearest pixels.
A color step gives a line about as wide as Radius on the side with
the larger sum, and a Radius of one pixel or less gives the same
edges as before. The edge modes' reach() includes the blurred copy
that a wide Radius reads.
On a 2,000 by 2,000 px image, Edge Only takes 0.49 s at Radius 10 and
0.34 s at Radius 100, and Normal takes 0.73 s and 0.39 s. Normal
draws the same pixels as before.

The PostScript interpreter that reads EPS and PostScript files had no
CCITTFaxDecode filter. Reading a file whose image data went through it
stopped at an error naming the filter, and the file opened from a
fallback, such as its preview or the art drawn before the image, or
did not open.
CCITTFaxDecode now decodes CCITT Group 4 (ITU-T T.6) and Group 3
one-dimensional and mixed (ITU-T T.4) data to rows of 1-bit samples.
It reads K, Columns, Rows, EndOfBlock, EndOfLine, EncodedByteAlign and
BlackIs1 (PLRM 3rd ed., §3.13; ISO 32000-2, §7.4.6). With EndOfBlock
the data ends at its EOFB or RTC regardless of Rows, and the RTC of
mixed Group 3 data, six EOLs each with a tag bit, is found by the
filter. Damaged data keeps the rows decoded before it, and damage in
the first row is an ioerror. Columns outside 1 to 65,535 and Rows
below 0 are a rangecheck, and data that would decode to more than
256 MiB is refused. hayro-ccitt 0.3.0, already in Cargo.lock through
hayro-syntax, becomes a dependency of vectorcraft-eps.
The tests encode their images in the test, with the fax crate's
Group 4 encoder and T.4 run codes (a dev-dependency, already in
Cargo.lock through tiff), and fail without the change. The import fuzz
tests read a Group 4 and a Group 3 image coded by hand from the T.4
and T.6 tables, read the same file with random damage, and add the
filter and its parameters to the hostile programs.

The EPS reader read PostScript by any name, but the Open and Place
dialogs hid .ps and .epsf files, and a .ps or .epsf file whose header
is only %! could not be opened or placed ("not a format VectorCraft
reads"). The reference app lists .eps, .epsf and .ps under Open and
Place.
- A read-only PostScript format (ps) joins the format table. A .ps
file opens and places through the EPS reader and reports the
ps format. document.export does not write .ps; file.print does.
- .epsf is an EPS extension.
- OPEN_EXTS and PLACE_EXTS list epsf and ps, so the dialogs, the CLI
help and the MCP open_file description list them.
UNASSOCIATED_EXTS lists them too: the macOS bundle declares neither.
- A .ps or .epsf file whose header is only %! now pastes as EPS when
copied in a file manager, as one with a %!PS header already did, and
clipboard.importEps reads PostScript whose header is only %!, which
it rejected before.

A double-click on a ruler guide with the Selection, Direct Selection or
Group Selection tool did nothing, whatever keys were held. A guide could
be released only with View › Guides › Release Guides.
With the Selection, Direct Selection or Group Selection tool, a
double-click with Cmd/Ctrl and Shift held now runs view.guides.release
on the ruler guide under the pointer (index) or, when no ruler guide
is there, on the guide path under it (ids). Nothing is released while
guides are hidden or locked, and a double-click without both keys does
what it did before.

The Character panel menu's Reset Panel reset tracking, leading,
kerning, baseline shift, the scales, rotation, underline,
strikethrough and All Caps, but left Small Caps, superscript or
subscript, Character Alignment, Proportional Metrics and Digits at
their custom values.
Reset Panel now also sets those five to their defaults in the same
text.setFormat call, with the values taken from CharStyle::default().
It resets them in the same characters as the other attributes: those
of the selected type, or, while the Type tool edits text, its
selection (all of that text at a caret). It resets them whether or
not Show East Asian Options and Show Indic Options (Preferences ›
Type) are on.
The Layers panel menu had no saved-selection items, and the Select
menu was the only menu that listed saved selections. The reference
app's help also names a Save Selection menu in the Layers panel that
lists the saved selections and holds Save Selection, Update Selection
and Edit Selection.
The Layers panel menu now has a Save Selection submenu after Locate
Object. It holds Save Selection…, Update Selection and Edit Selection…,
which are enabled and run as in the Select menu, and below them the
active document's saved selections. Choosing a name runs select.recall
with that name, as the Select menu's list does.

Native files remember the grid like the saved view, so reopening restores it.
Toggling it is still view state: no undo step, document not marked modified.
