As Illustrator's help describes (Filter fonts by classification, Font Technology › Variable), the font menu gets a Font Technology row whose Variable choice lists only the families with variation axes, together with the script, kind, favourites and search filters, and stays set from one opening to the next. A family is variable when any of its faces, loaded or scanned, has an `fvar` table, so a family installed as static files beside a variable one counts.

COLR and SVG glyphs, which have no outlines, were left out wherever type was taken as its outlines: geometry effects, Expand Appearance, EMF/WMF export.
A root size without a viewBox sets up the em, a viewBox that isn't square is centred in it, and a glyph element nested in others is drawn on its own, as if used.
A PDF names fonts by PostScript name. When the font isn't installed at import, the importer
splits the name (`Honoka-Mincho` → family Honoka, style Mincho) and the document keeps that
pair. Installing the font later didn't help when its family name shares nothing with its
PostScript name (ほのか明朝): the pair stayed missing. FontDb::canonical now also looks the
pair up, joined, among the PostScript names, and answers with that face's own family and style.
The renderer placed symbol art that holds a blend, an envelope or a
repeat again for every instance in every frame. The live object in the
placed copy was a new node each time, and the renderer evaluated it
again. Symbol art that is itself a live object, an opacity mask whose
art is one, and a live object in a clip group in Outline view were
drawn from an uncached copy in every frame. At 1000 x 1000 pixels,
2,000 instances of a symbol holding an envelope took 126 ms a frame on
main, and the same 2,000 envelopes on the page took 30 ms.
The renderer now keeps the placed art of instances and inline graphics
when it holds blends, envelopes or repeats, and when the art is itself
a live object. It draws kept live art, opacity-mask art and Outline
view clip members that are live objects from the live cache, which
evaluates them again when the symbols, patterns, fonts or color
settings they show change. The 2,000 instances take 28 ms a frame,
with the same pixels.

Review follow-up (CodeRabbit, clean-room): the test header, gaps.md and
target-app-parity.md quoted a phrase from the cited help page. Comments
and docs only.
The Simplify help page says a path can be simplified whole or "a specific
path region with the Direct Selection tool"
(https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/modify-paths/manually-simplify-paths.html).
Simplify refitted every selected path whole, whatever part of it was
direct-selected.
object.path.simplify now looks at each path's direct selection: the
segments picked as segments, or else every segment with both anchors
selected. Each run of consecutive selected segments is refitted on its own
(vectorcraft_pathops::simplify_part) between its two end anchors, which stay
where they are with their handles on the side away from the run; every
other anchor and segment stays exactly as it was. A closed path's run may
cross its start point (the path then starts at the run's end anchor),
separate runs on one path simplify independently in one undo step, and the
runs stay direct-selected (as segments when segments were picked). A path
with only lone anchors selected still simplifies whole, as before, and
wholePaths: true simplifies partly selected paths whole. The slider, its
preview, Auto-Simplify and the Simplify dialog all run the command, so
they act on the part too. simplify_with now shares its run fitting with
the part refit (same results).
Verification: crates/engine/src/tests_simplify_part.rs (unselected anchors
and segments equal bit for bit, run end anchors fixed, the run within the
tolerance, two runs equal to each simplified alone in one undo step, a
closed run across the start point, picked segments, wholePaths, slider
preview and Auto-Simplify, a run that can't be simpler records no step)
and simplify_slider_and_dialog_simplify_only_the_direct_selected_part_of_a_path
(the slider's preview, Enter and the dialog's OK). Live: the release build's
slider at level 20 on a 91-anchor wave with anchors 30–60 selected refits
only that stretch.
A file opened or placed off the UI thread waited while the active tool
reported busy. The Dimension tool also reports busy between its clicks,
so after one click a ready file stayed queued with its spinner until
the dimension was finished or canceled. Files also waited between the
clicks of the Blend tool.
The session now records whether the pointer button is held. A file
waits for a busy tool only while the button is held. A file that
opens between a tool's clicks resets the tool, as a switch of
documents does; a file placed in the active document leaves the
tool's clicks in place. Files still wait while a dialog is open, a
drag is under way or a preview is open, and a tool's preview between
its clicks counts as one (the Flare tool after its center drag, the
Dimension tool's line once the pointer moves after its second click).
The drawing modes help page
(https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/learn-drawing-basics/drawing-modes-overview.html)
has you draw or paste into the selected object in Draw Inside. The isolation
help page
(https://helpx.adobe.com/illustrator/desktop/manage-objects/select-objects/isolate-objects.html)
isolates a path, group or object on a double-click with the Selection tool,
and puts art added in isolation mode where the isolated art was once the mode
ends, so that art belongs with what is isolated.
Steps: select a path, choose Draw Inside, double-click the path with the
Selection tool (it is isolated), then draw or paste. The art went into the
clip group Draw Inside makes around the path, but isolation mode stayed on the
bare path, so the new art was outside it: drawn dimmed, passed through by
clicks and marquees, and a double-click on it selected the path and never
entered the clip group. Double-clicking an existing Draw Inside clip group
from outside isolation mode already isolated it, and pastes then went inside
it; that is unchanged.
Cause: create::insert_look_turned and edit::paste_clip put the art into
create::draw_inside_group's clip group but left DocState::isolation on the
object drawn into, and with a single object isolated, hit testing reaches
only that object.
Change: when the object drawn into is the isolated one, isolation moves to its
clip group (create::isolate_draw_inside_group), after new art and after Draw
Inside pastes. A drag's previews replay from its snapshot and make the group
under the same id, and cancelling the drag restores the isolation it began
with. Undo and redo end isolation mode when the isolated object is no longer
in the document (the undone clip group), as mask editing already does,
instead of keeping an id a later object may take.
Verification: drawing_inside_an_isolated_object_keeps_the_new_art_in_isolation_mode
fails without the change (isolation Some(NodeId(2)) instead of the clip group
Some(NodeId(6))). A whole-window egui run through the control channel's
ui.click/ui.drag (double-click the rectangle, drag an ellipse inside, paste,
click the copy) left isolation on the rectangle and the click selected the
rectangle before; after, isolation is on the clip group and the click selects
the copy.
Converting a frame of threaded text to point type left the frame's
text in the point type, and the re-flow also added that text to the
story, as it does for a frame that was deleted. The other frames then
held it a second time.
A frame that is still in the document as point type now leaves its
thread with the text it holds. The story flows through the other
frames without that text, so each character is held once. A thread
left with one frame is no longer a thread, and undo restores the
thread.

#3836 added the message without @msg rows, so
complete_languages_translate_every_message fails on main (cs first, then
every language in COMPLETE_MESSAGES). Each row follows the catalog's own
"PDF settings are not an object" row and its word for Security.
On Linux under X11, and under XWayland, winit 0.30 hands a drawing
tablet's pen to the window as a mouse without its pressure. Every pen
stroke reached the tools at full pressure: a Calligraphic brush with
Size on Pressure drew one width, and the Liquify tools' Use Pressure
Pen applied full intensity.
When the window is on X11, the desktop app now reads XInput2 raw
events on a second X connection (x11rb's RustConnection, without
unsafe). A device with an "Abs Pressure" valuator is a pen, unless
its XInput type is TOUCHPAD or TOUCHSCREEN. Its pressure, scaled from
the valuator's range to 0..1, goes into Services::stylus, and another
pointer moving clears it. The canvas uses that pressure when a frame
has no touch force. A press takes the highest pressure of the pen's
latest touch since the canvas last read the feed, and waits up to
5 ms for the touch of a hovering pen. The moves and the release of a
held press keep the pressure the pen last touched with when its lift
has already arrived. Native Wayland is unchanged.
The valuator mapping and the reader come from PhotoCraft's tablet
crate (storytold/photocraft#255), with the pressure axis only.

Many tools note things on SVG objects in attributes of their own XML
namespace: a plotter's pen, a cutter's passes, a game engine's
collision flag. Import dropped them, so a file that went through
VectorCraft lost what other software had set on its objects. #522
asked for unknown and data-* attributes to survive a round trip; #580
kept the data-* ones, and this keeps the ones in other applications'
namespaces.
- Import keeps every attribute in a namespace that isn't SVG's,
XLink's, XML's, Inkscape's, Sodipodi's or VectorCraft's own, on the
object or layer it belongs to, in order, with its namespace URI and
the prefix the file gave it (ObjectAttributes::foreign, beside the
data-* attributes and the event handlers). The file is untrusted: at
most 64 per object and 64 KiB per value, and what is left out is
warned about. Files that declare no other namespace skip the scan.
- They are the object's own, as its data-* attributes are: a pasted
copy and a duplicate keep them, and deleting the object takes them
with it. The native file keeps them in the object's attributes, a
key written only when an object has some.
- Export writes them back on the same elements and declares each
namespace once, on the root, under the file's prefix. A prefix the
export uses itself, or that another namespace already has, becomes
prefix2, prefix3...; one XML keeps for itself (xml...) becomes ns. A
name or value XML can't hold is left out with a warning.
Nothing in VectorCraft reads them, and nothing in the UI lists them.
svg/tests/foreign_attributes.rs: a layer's and a shape's attributes
survive import, export and import again, Inkscape's and Sodipodi's
own aside and with no warnings, and the native form round-trips;
prefixes are made unique, and bad names and values are left out with
a warning; the caps hold and are warned about once.
engine tests_attributes.rs: a pasted copy and a duplicate keep them, a
deleted object leaves none behind, and the native file and SVG export
keep them.

Claude-Session: https://claude.ai/code/session_01HhvnnnD5fTFupK8WWq35un
Cause: since #3742 place_each measures a line's spacing from the file's
own widths, so tracking is only the file's Tc/Tw/TJ. Where the widths
are systematically off the installed font's advances (up to the 1% that
still counts as the same font), those differences add up along a line
and nothing made up for them. With no kerning and every tracking value
0, place_each returned the untracked layout early, without the 0.02 em
placement check (CodeRabbit's review of #3742): a line of embedded
Source Sans 3 with /Widths 0.8% wide opened 3.7 pt off. With the early
return removed the check rejects the line and the line-wide fit takes
over: one whole-thousandth tracking value with the font's kerning,
0.30 pt off (as before #3715). Before #3742 main placed it exactly but
with a run per character (49 and 62 runs).
Change: the early return is gone; every line goes through the check.
Before it, on_course() keeps the file's spacing where the glyphs stay
within 0.01 em of the file's; otherwise each stretch of the line takes
one share after every character (the longest stretch one share keeps
within 0.01 em), so ordinary text stays one run, and a line whose
differences change course (30 m then 30 i) takes a run per stretch (2).
Verification: new test
a_long_line_of_widths_a_little_off_the_fonts_advances_lands_in_one_run
(embedded Source Sans 3, widths x1.008 and x0.992, a kerned and an
unkerned line): one run each, glyphs under 0.24 pt (0.02 em) from where
the file draws them. Without on_course it fails after #3742, with and
without the early return ("glyphs 0.300 pt"); before #3742 it fails on
the run count. It replaces an Inter test drafted for the review: Inter
isn't embedded there, so the file's outlines are the interpreter's
stand-in stretched to the widths, not Inter, and the contours differ by
0.6 pt even with exact widths. tests_text_placement and
text_becomes_point_type pass; cargo xtask ci: all 10 steps passed.
Thanks to the CodeRabbit review on #3742 for the early-return finding.
Review follow-up (CodeRabbit): the clip group's mask copied the target with
only a new root id, so a compound path's subpaths had the same ids in the
mask and in the object. The mask is now Document::reid's copy. Paste on All
Artboards with only an artboard on the clipboard made an empty Draw Inside
clip group; it now needs objects to paste.
draw_inside_a_compound_path_gives_its_mask_ids_of_its_own: without the
change an id is used twice (7 ids for 6 nodes).
The drawing-modes help page
(https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/learn-drawing-basics/drawing-modes-overview.html)
has you draw or paste into the selected object in Draw Inside. It also says
the modes apply to Paste in Place and Paste on All Artboards but not to Paste
in Front or Paste in Back.
Cause: only new art (create::insert_look) read the drawing mode. The paste
commands (edit::paste_clip) always used the insertion parent, so a paste in
Draw Inside landed on the layer above the object, outside the clip.
Double-clicking the object first only isolated the bare path, which didn't
change where the paste went. Separately, view.drawMode {} went from Draw
Behind to Draw Inside whenever one object was selected, then refused it unless
the object was a path, compound path or type. So with one group selected
(such as the clip group Draw Inside makes), Shift+D and the toolbar button
failed every time and stayed in Draw Behind.
Change: the clip-group wrapping moves into create::draw_inside_group, which
new art and pastes now share. In Draw Inside, Paste, Paste in Place and Paste
on All Artboards insert the copies at the top of that group, in the paste's
one undo step, ignoring Paste Remembers Layers. In Draw Behind, Paste in Place
and Paste on All Artboards go just below the selection, as Paste in Back does.
Paste in Front, Paste in Back and pasted artboards keep their placement.
Shift+D goes on to Draw Inside only when it can draw into the selection, and
otherwise back to Draw Normal.
Verification: pasting_in_draw_inside_puts_the_copies_inside_the_object,
paste_in_place_in_draw_behind_goes_behind_the_selection and
shift_d_goes_past_draw_behind_whatever_is_selected all fail without the
change ("Layer" != "Clip Group"; index 3 != 0; the Draw Inside error on a
selected group). cargo xtask ci: all 10 steps passed.
