#6716 added the member index to each solid part after #6754's shadow
code was written against the five-field tuple, so main stopped compiling
once both landed. The Inflate, Extrude and shadow-drawing loops now
destructure all six fields.
Revolve, Extrude & Bevel, Inflate and Rotate take a Shadows switch on the
Lighting tab, with Position (Behind Object or Below Object), Distance from
Object (0 to 100%) and Shadow Bounds (10 to 400%), saved in the effect as
shadow, shadowPosition, shadowDistance and shadowBounds.
With shadows on, the first light casts a hard-edged vector shadow of the
solid: every face of every solid of the object projected along the light
onto a plane behind the object (square to the view) or below it (square to
its own vertical axis and turned with it), filled black with the nonzero
rule at 50% times the opacity of the art that casts it, in that art's
blending mode, and drawn behind the solids. Distance moves the plane away
by a share of the object's largest size; Bounds ends the plane at a square
about the foot of the object's center, four times that size across at
100%. No shadow is drawn while Shading is off, when the first light's
intensity is 0, or when it does not reach the plane. A member's opacity
mask and blending mode apply to the part of the shadow it casts. A shadow
is cast from at most 327,680 faces; past that, commands are refused and a
loaded file draws the source path. The canvas, SVG and PDF exports draw the
shadow, and Expand Appearance keeps it as a path. Values out of range are
refused before the document changes.

Extrude & Bevel (both kinds) and Inflate drew the faces of the fill's
solid and the stroke's solid in one order by each face's center depth.
At a concave corner a long fill wall could sort after a stroke wall in
front of it, so stripes of the fill showed through the stroke.
- Facets now record whether they are side faces (walls, bevels,
Inflate's sides) and whether they are turned away from the viewer.
- With caps on, each fill side face turned toward the viewer is drawn
before every face of the same shape's stroke whose bounds overlap
it, for strokes whose solid hides the fill's whole edge: a closed
shape, a width, no dashes, width profile or brush, and a solid color
or a gradient without transparent stops. Caps, other shapes in a
group, hollow effects and translucent or blended surfaces keep their
order.

When a layer effect moves a sublayer's ruler guides onto the layer, a
guide inside a hidden or locked group now stays hidden or locked, as it
does for a hidden or locked sublayer.
- A layer with a Pathfinder effect, or a Transform effect that copies its
art, keeps the ruler guides of its sublayers on the layer, hidden and
locked as their sublayers were, instead of losing them with the art.
- Opening a file counts the ruler guides of sublayers removed beyond the
canvas.
- Opening a file moves misplaced ruler guides above the art before the
canvas check, so a guide saved before a clipping path beyond the canvas
no longer makes other art the clipping path.
Follows #6632.
With Envelope Options > Distort Appearance on, VectorCraft turned the strokes
of type in an envelope into filled outlines and bent them with the art, so a
stroke got thinner where the grid squeezes the type and thicker where it
stretches it. The drawn art of users' .ai files keeps those strokes as stroked
paths at the type's own weights, and the ring they paint is as wide wherever
the grid squeezes or stretches the type. An envelope of stroked type in such a
grid therefore didn't draw as its drawn art and kept it instead of opening live.
Type's strokes (its characters' and those on its own appearance) now paint
along the bent glyph outlines at their own weight, with Distort Appearance on
or off, also in an envelope inside an envelope:
- doc: `map_node` maps the groups that hold type's glyph outlines with
`Hooks::type_appearance` in place of `Hooks::appearance`, for type in the
envelope's contents and for type that a live object in them (an inner
envelope) outlined (`Warper::type_outlines`). Such a group's opacity mask
is mapped with the ordinary hooks, so it bends as other art does. Groups
marked as type's outlines in the contents themselves (art an earlier Expand
made) stay plain art.
- effects: `bake_type_appearance`, `bake_appearance` with strokes kept as
strokes: geometry effects on type's fills and strokes still bake in and bend.
- doc: `max_outset` counts type's character strokes as type's own visual
bounds do (`char_stroke_outset`). It left them out, though they already
painted past an envelope's grid where the glyphs reach its edge; this also
grows the visual bounds of blends and repeats of stroked type and the reach
of symbol art holding it.
Paths' strokes, geometry effects, opacity masks, linear gradients and pattern
fills bend as before. The canvas, hit testing, effect bounds, Expand, every
export and the .ai save take the evaluation from the same hooks. Expand of an
envelope of stroked type gives the bent outlines with the strokes on them.
This changes how VectorCraft's own envelopes of stroked type draw.

Ruler guides were a list kept beside the layers. Each guide is now an
object of its layer or sublayer, always directly in it and above the
layer's art. These behave as on main:
- Guides draw on screen only. Exports (SVG, PDF, PNG, PSD), Fit All,
Select All, the art bounds, clicks and marquees, and a layer's
Pathfinder and Transform effects leave them out. The Layers panel
lists them as guide rows of their layer, the highest guide.list
index first.
- Deleting a layer deletes its guides, and merging layers keeps their
guides in the merged layer.
- The guide commands number guides as guide.list does, in the order
they were made.
New: each guide takes an id from the document's object ids. An object
command given a guide's id fails with an error, and node.move cannot
put a guide into a group or out of its layers. A guide made while an
opacity mask, a symbol or a pattern is edited moves to the top
visible, unlocked layer when editing ends.
File format: native files still save the guides in the document's
guides list, in every file version, so older builds read them. Each
entry may now also carry the guide's id, name, locked and hidden
flags; older builds ignore those fields. Opening a file puts each
saved guide on its layer (on the top visible, unlocked layer when the
file names none or a layer it does not have), and each saved guide
counts against the object limit for opening a file. A ruler guide node
that a file holds below a layer's art moves up to the layer's guides,
and one anywhere else (in a group or another object, beside the
layers, or in a symbol) is removed. Ruler guides read from an .ai file
become guide objects on the layer they were on, numbered in the order
the file lists them.
The blending-mode test for a member of a 3D group now checks that every face of the multiplied member, and no face of the other member, is drawn inside the Multiply group, telling the members apart by height. Before, it only checked that some faces were multiplied and some were not, so it also passed when the mode went to the wrong member.
On a group, these effects drew every member's solids in Normal mode: only
an opacity mask on a member or on a group inside the 3D group was applied
to the solids it holds. A member's blending mode, and that of a group
inside the 3D group, now apply the same way, to the solids of the members
it holds together. Group Revolve already did this.
Paste renamed a pasted SVG filter to a name no filter of the document
held, but an effect could still use that name, for example after its
filter was deleted. Defining a filter of that name later changed both
effects. Paste now also skips the names the document's effects use,
read only when a pasted filter needs a new name.
A new name with a tab, line feed or carriage return was written into
the filter's id as is, which XML reads as a space, so the id no longer
matched the effect's name. svg_filter::with_id now writes those
characters as character references, and paste takes a name only when
the filter's id reads back as that name.
Expand Appearance on a symbol instance with a fill tint and a color
adjustment applied the adjustment to the untinted art, so the expanded
colors differed from the canvas. The expand path now passes the tinted
instance art to adjust_in_document.
While the app draws a document on screen, the live-effect plug-in runs of
its first view share a 2,000 ms budget (VectorCraft's own value); each run
takes the lesser of its 5,000 ms limit and what is left. A stage left out
for time, or one that times out, fails, has no plug-in or meets Safe Mode,
draws its input art unchanged and is deferred, and the status bar says how
many. Later drawings leave a deferred stage as it is until its input or
parameters change.
- effect.deferredStatus lists the deferred stages with object, effect
index, fill or stroke, plug-in and reason, objects in symbol, pattern,
brush and opacity-mask art included.
- Effect › Refresh Deferred Effects (effect.refreshDeferred {ids?}) runs
them again with a fresh budget and returns {refreshed, stillDeferred,
failed}.
- Each document has its own budget and deferred stages; exports, Expand
Appearance and commands run every stage under the per-call limit.
- The web build has no clock for the budget: its first view runs no
plug-in effect, and a refresh runs them.

A 3D effect on a group built its solids from the members' paths and
paint and left out each member's opacity mask, and the mask of a group
inside the 3D group. Clipping groups, blends and symbol instances
resolved for the effect lost their masks the same way.
A member, or a group inside the 3D group, with an opacity mask now
gets a scope like one with its own opacity or blending mode, and the
mask goes on the group that holds that member's surfaces. Revolve
applies it with the member's opacity and blending mode; Extrude &
Bevel, Extrude & Bevel (Classic), Inflate and Rotate draw each solid
on its own when a mask is present and put the masked members' solids
in a group with the mask. A resolved clipping group, blend or symbol
instance keeps its mask. A disabled mask is ignored.
The check that refuses a symbol instance before its art is placed
counted only the symbol's own objects. Placing art through 9-slice
guides can make up to 28 objects of each one, and an instance's
dynamic-symbol overrides can turn a path that would be cut at the
guides into clip groups in every cell it reaches. Such an instance
passed the check, and its art was placed in full before the work
limit refused it.
The check now counts the symbol's own objects first, then the most
objects placing makes (NineSliceMap::most_placed) of the art with the
instance's overrides applied, and refuses the instance with the same
message before anything is placed.
A 3D effect on a symbol instance placed a copy of the symbol's whole art
before counting it against the effect's work limit, so a symbol far past
the limit was copied in full on every check and redraw before it was
refused. The symbol's objects are now counted first, and a symbol that
would pass the limit is refused with the same message without being
placed.
The message for a group member that can't become a solid now names groups
and clipping groups too. docs/three-d.md states that an image left out of a
clipping group also needs no visible fills or strokes of its own.
Inside a clipping group, the fills of a shape were cut into one piece in
the top fill's place. Rotate turns every fill, so with a fill, a stroke
and a fill, the lower fill was drawn above the stroke. With Rotate, each
fill now becomes its own piece in its own place. Extrude & Bevel, Inflate
and Revolve build from the top fill and keep one piece there, also when
an object changes from Rotate to another 3D type.
Inflate's grid clipped every ring of the outline in each cell the
outline crosses and tested every edge for each cell's center, so its
work grew with the outline's points times the cells: a comb of 4,000
teeth (16,002 points) took 1.1 to 1.3 s and one of 16,000 teeth 8.8 to
9.1 s. Inflate now counts that work (the edge index's entries, the edges
its queries look at and the ring points its cells clip) and refuses the
shape with "The 3D surface is too complex; simplify the shape" once it
passes 268,435,456, VectorCraft's own value (about 0.65 s). The index
takes at most 16,777,216 entries (64 MiB). Each row's inside test reads
the sorted crossings of its line, and a cell clips only the rings whose
bounds meet it, so a 65,536-point circle inflates in 0.66 s instead of
1.0 to 1.2 s.
The effects test of a stroke past the limits uses 40,000 corners, so its
outline passes the 65,536 points a solid takes.
Docs: docs/three-d.md, docs/mcp.md.
A clipping path nested past the depth limit, and a group at the limit
that holds further groups, are refused before they are walked, instead
of being followed to any depth. The clipping path's check follows the
members its outline is built from: the first member of a nested
clipping group and the shown members of other groups. The group check
skips hidden members and treats a compound path as one shape, as the
solid builder does.
An image in a clipping group whose bounds lie wholly outside the clipping
path's bounds draws nothing, so a 3D effect leaves it out instead of
refusing it. An image with effects, fills or strokes of its own, or one in
a group with effects inside the clipping group, is still refused, since
those can draw it inside the clip.
- When a group's geometry effects reshape its members inside a clipping
group, each member's piece goes back into groups with the opacity and
blending mode of the groups it was in.
- A clipped shape's pieces (its fills and each stroke) are counted against
the 4,096-object and work limits before they are cut.
- Resolving the symbol instances, blends and clipping groups a 3D effect
builds from counts every object it visits or makes and stops past
262,144 with an error. Nested symbol instances that end in hidden art
are refused instead of being expanded at every level. Each object is
visited once; a group is no longer walked again for each level above it.
- A symbol instance, blend or clipping group inside a 3D group keeps its
appearance, so its geometry effects reshape the art it shows. A nested
group's geometry effects now reshape its members inside a 3D group too,
and inside a clipping group they apply before the clip cuts the art.
- Hidden members and guides of a group inside a clipping group build no
solid.
- Tests cover an empty clipping group, a blend set to no steps, an
instance of an empty symbol, a symbol holding a clipping group, the
paint-copy budget across resolved art, and art past the limits drawing
as it does without the effect.
Extrude & Bevel, Extrude & Bevel (Classic), Inflate, Rotate and Revolve
now apply to a clipping group (or a layer with a clipping mask), a blend
or a symbol instance, alone or inside a group or layer. The solid is
built from the art the object shows: the art inside the clipping path
(fills cut to the clip, strokes as their outlines cut to the clip), the
blend's keys and steps, and the symbol's art where the instance places
it. Validation, the canvas, bounds, Expand Appearance, Rasterize and
assets.add3D read the same art from the document.
An image is refused, alone or in a group, with a message to trace it
first with Object > Image Trace > Make. A missing symbol, a symbol that
holds an instance of itself, art nested more than 64 levels deep and
more than 4,096 objects are refused. The refusal messages change, and
their rows change in every catalog.

With Measure Type by Glyph Bounds on, point type is measured by its
glyph outlines and its underline and strikethrough bars, as the canvas
draws them. A typed W or H gives what is drawn that size, and underlined
or struck-through spaces are measured by their bars instead of the em
box.
The texts now say that each point type object selected as an object
(not inside a selected group) is measured this way, that moved type
snaps by its ink box, and which Arrange Tools commands follow the
option: Swap Objects, Replace with Top Object, Set Size of Each and
Sort Objects. Arrange in Grid and Group Overlapping Objects keep
measuring visual bounds.
A face of a group member that paints nothing (its fill or stroke at 0% opacity) was drawn without a group, so its zero opacity was lost and the member drew fully opaque. Such a face now keeps a group with the opacity and blending mode of its fill or stroke.
Measure Type by Glyph Bounds (`typeGlyphBounds`, off by default) is in
Preferences > Type > Glyph Bounds and the Transform panel menu. With it
on, the bounding box, the Transform, Control bar and Properties X, Y, W
and H, `object.setBounds`, the transform tools' reference point and the
Arrange commands measure point type selected on its own by the ink of
its glyphs instead of its em box. A typed W or H scales the live type
until its ink has that size.
- The engine caches each type object's ink in text space with its
layout bounds; the cache is not saved.
- Use Preview Bounds adds the characters' strokes, and type with
geometry effects is measured as drawn. Skewed type is measured by its
outlines.
- Type that draws nothing, area type, type on a path and type inside a
selected group are measured as before. Align and Distribute keep
following Align to Glyph Bounds.

When any member of a revolved group had an opacity below 100% or a
blending mode, every member's surface was drawn whole in member order,
so the opaque members lost their shared depth sort and a transparent
member drew entirely over or under the others.
Every member's faces are now sorted into one order. Opaque faces go in
that order on their own. A transparent member's faces share one group
with its opacity and blending mode, and its scopes group them further,
unless a face of another member that overlaps them on the page lies
between them in the order; only there is the member split. Faces
overlap when the convex hulls of their outlines come within the 0.75 pt
seam stroke of each other. Faces that paint nothing never split a
member. Past 4,194,304 overlap tests on one group, each further face
of such a member is drawn as a part of its own.
Docs: docs/revolve.md.
effect.setParams checks a Revolve before the edit, so turning a hidden Revolve back on measured
its profile after every geometry effect on the object, those after the Revolve included, and could
refuse a profile that draws. The check now measures the profile after only the geometry effects
before the Revolve, hidden or shown, as drawing does. An object holds at most one Revolve, hidden
ones included, so the check finds the same one that draws.
The opacity of a group inside a revolved group was multiplied into each member's surface, so where members overlap they drew darker than the group does without the effect. A member or group with opacity below 100% or a blending mode other than Normal now holds its members' surfaces in one group with that opacity and mode.
With Use Preview Bounds on, the visual box of a butt-capped stroke on an
open path grew by half the stroke weight past each end of the path, where
a butt cap paints nothing. A 2 pt vertical line set to H: 10 mm in the
Transform panel drew about 9.3 mm long.
The box of an open subpath with butt caps no longer reaches past its
ends. A straight segment's box comes from the four corners of its stroked
rectangle, and a curve's box comes from the stroke at its ends and where
its tangent is square to an axis. Bevel joins, and miter joins the limit
bevels, are measured by the stroked corners, and round joins by the arc
they paint outside the turn, instead of half the weight all round. Round
and projecting caps, arrowheads, closed paths and miter tips measure as
before. Two cases can still measure larger than the stroke paints: a
curve that bends more tightly than half the weight, and a butt-dashed
path whose first or last dash is a gap, which is measured to the path's
ends.
A horizontal or vertical butt line now measures one stroke weight less
along its length in W or H, and Align places it by its end points. A
slanted line's box shrinks by less: the stroke's corners still reach
past the end points across the line. object.setBounds measures as drawn,
after each scale it tries, a butt-capped open path with a segment at a
slant, symbol instances' art included.
A member of a group with Revolve drew its surface in Normal mode whatever its own blending mode or that of a group it is in. Each mode now applies once, to the member's surface or to the surfaces of the group that has it, nested as the groups are. Expand Appearance keeps every face of a blended member.
