The widget's Constrain button was grayed out in Free Distort, and
neither it nor Shift changed a Free Distort corner drag. Constrain is
now available in Free Transform and Free Distort, and stays unavailable
in Perspective Distort.
With Constrain on, or Shift held, a corner dragged in Free Distort
moves only along the line through the opposite corner, in the box's
own proportions, and the other three corners stay in place. On a
turned box the line runs through the box's own corners. A box with no
size leaves the corner where it is. Cmd/Ctrl+Alt+Shift on a corner
still drags in Perspective Distort. The measurement label shows how
far the corner moved.
Control bar > Snapping > Pixel Snapping Options... opens a dialog with
three checkboxes: Snap to Pixel While Drawing, While Moving and While
Scaling. OK sets them; Cancel leaves them as they were. While View >
Snap to Pixel is off, the dialog notes that the options take effect once
it is on.
- view.snapToPixel.options {drawing?, moving?, scaling?} reads and sets
them. They are kept in the preferences as the pixelSnap group, all on
by default, so turning Snap to Pixel on behaves as before. An unknown
key or a value that is not a boolean is refused and changes nothing.
The command has a parameter schema, which raises the API level to 4.
- Drawing covers points the drawing tools place, the Knife's straight
cut, the Measure tool and the rulers' origin. Moving covers Selection
and Direct Selection moves, ruler guides, artboard moves and the
Rotate, Reflect and Shear tools' drags. Scaling covers bounding-box,
Free Transform, artboard and slice handles and the Scale tool's drag.
An edit whose option is off snaps as it does with Snap to Pixel off.
- Align New Objects to Pixel Grid and the objects' pixel-aligned
property do not depend on these options.
Docs: docs/mcp.md, docs/target-app-parity.md.
After a rotation the Selection tool already shows and drags a bounding
box turned with the objects, but the Free Transform tool still used the
page-aligned box. Its handles sat on the wrong corners, a side handle
scaled along the page axes, and Perspective Distort and Free Distort
started from a box that did not match the art.
- The Free Transform tool keeps the selection's turned box for the
drag. Handles, the rotate zone and the move zone are read in its
frame; a handle scales along the selection's own sides from the
opposite handle (or the center with Alt) and snaps as the Selection
tool's does; Cmd/Ctrl on a side handle shears along that side; the
outline, handles and cursors are drawn on the turned box.
- Perspective Distort and Free Distort move the corners of the turned
box. `object.distort` takes `angle?` (degrees): `from`, or the
selection's bounds without it, is then a box in the frame turned by
that angle. Upright boxes send the same params as before.
- The Scale and Reflect tools, their dialogs and commands, and the
Transform panel's flips keep the page's axes.

A linear, radial, conic or diamond gradient has a spread: Pad (the
default, as before), Repeat or Reflect, with a count of 1 to 100
(VectorCraft's own limit). Repeat and Reflect run the stops that many
times along the vector (around the turn for a conic) and keep going past
both ends, Reflect running every other run backwards, as SVG's
spreadMethod does.
The Gradient panel has a Spread menu and a Repeats field, and the
Gradient tool marks where the runs meet. paint.setFill and
paint.editGradient take `spread` and `repeats`; bad values are errors.
Presets, swatches, blends, strokes along or across a path, Outline
Stroke and Object › Expand follow the spread; Expand gives each run the
same whole number of objects, and Outline Stroke's mesh keeps the color
on each side of a sharp step between two stops at one offset.
SVG writes and reads spreadMethod: SVG import now reads a repeating or
reflecting gradient as one that repeats or reflects once, instead of
expanding its stops over the shape. CSS writes repeating gradients.
PDF writes a conic's sweep shading over one run. PDF, EPS, legacy .ai
and the .ai editing data write the other kinds with their stops
repeated across the shape: at most 256 runs and 16,384 stops (256 stops
in .ai files), and for a radial or diamond no farther than 65,536 runs
from its center, with a warning past those. PDF import now finds sharp
steps in any axial or radial shading instead of blurring them.
Docs: docs/mcp.md (Spread), docs/target-app-parity.md, docs/gaps.md.
A new gradient kind, `diamond`, runs its stops from the center (the
start) out to a square with a corner at the end of the vector; the
aspect stretches the square across the vector into a rhombus. The
Gradient panel's Type row has a Diamond button, the Gradient tool draws
the square with the aspect handle and center ring, and a gradient
fitted to an object covers its box.
- Model and canvas: the level is |x| + |y| in the square's frame; a
square with no area (no vector, an aspect of 0, numbers out of range)
paints the last stop. The canvas draws it as pixels, out to a
stroke's miters, caps and arrowheads. Transforms keep the vector and
take the mapped size across it as the aspect.
- Commands: `paint.setFill`, `paint.editGradient` and
`paint.setGradientGeom` take `kind: "diamond"`; a negative aspect or
a focal point is an error. A conic or diamond gradient that a plug-in
returns with a focal point loses the focal point.
- Gradient tool: dragging the aspect handle of a radial or diamond
gradient whose file gave it a negative aspect now sets a positive
aspect; only a conic's negative aspect mirrors it.
- Export: PDF, SVG, EPS and legacy .ai write four linear gradients, one
for each quarter of the square, clipped to the shape (PDF as axial
shadings). PDF and SVG write an image for translucent stops, a
dithered fill or a flat square, and for the Perceptual method unless
PDF writes the stops as spot color shadings. SVG writes a diamond on
type characters as a radial gradient through the corners, and so
does CSS. A swatch library saved as CSS gets four corner layers, a
value for the `background` property (a circle when the swatch is
turned by an angle that is not a multiple of 90 degrees). The .ai
editing data holds a radial gradient through the corners. The
document exports give a warning.
- SVG export: a stroke drawn as an image, as conic wedges or as diamond
quarters now covers the miters, caps and arrowheads that reach past
its paint box.
- PDF import reads a function-based shading whose color is the same
along each square about the origin of its space as a diamond.
- Object > Expand gives nested squares or a mesh of rings.
Docs: docs/mcp.md, docs/target-app-parity.md.
Each of the fifteen Warp styles now bends the bounds as one Bézier patch.
The style sets the patch's control points from the bend and the size of
the bounds, the horizontal distortion scales each column of control
points about its middle, and the vertical distortion scales each row.
The Warp effects and warp envelopes share the map (`WarpNet`). Content
with no width or no height takes the middle of the patch along that
side.
A warp carries the map it draws with as `version`. New warps, the
built-in graphic styles' Warps and warps opened from .ai files get 1.
Warps in .vectorcraft documents saved before the version existed read
as 0 and keep the earlier map, so those documents keep their look.
Edits keep a warp's version, and Warp Options editing several objects
keeps each one's own. effect.apply, effect.setParams and the warp
envelope commands take `version` 0 or 1 (`1.0` counts as 1) and refuse
any other value. An .ai file holds a warp's settings and not its
version, so a version 0 warp saved to .ai opens again with version 1.
The .ai writer compares a style's settings without the version, so
saved warps still export as editable effects.
Docs: docs/mcp.md (Envelopes), docs/effects-parity.md (Warp),
docs/target-app-parity.md.
A fourth gradient kind, conic (also accepted as `angle` or `conical`),
sweeps the stops once around the center (the gradient's start),
clockwise on the page from the vector, with a seam where the last stop
meets the first. A negative aspect mirrors the sweep, and reflecting an
object turns its sweep the other way, also for a conic without a
vector or with a flat extent.
- Gradient panel: a Conic button in the Type row; the Aspect Ratio
field works for conic gradients and keeps a mirrored sweep mirrored.
- Gradient tool: the extent ellipse, aspect handle and center ring of a
radial gradient, without a focal point.
- Rendering, swatch chips, transforms, warps, plug-in round trips, and
Object > Expand into wedges or a mesh of columns around the center.
- Commands: a negative `aspect` is an error for linear and radial
gradients, and so is a `focal` point for a conic gradient.
- PDF export writes a function-based shading whose calculator function
turns the angle into the ramp, and PDF import reads a function-based
shading that turns around the origin of its space back as a conic
gradient, also when that origin lies outside the painted area. A
PDF/A file, or a conic with more than 97 stops, gets an image
instead.
- SVG export writes 360 solid wedges clipped to the shape for opaque
stops and an image otherwise, and a linear gradient on characters.
- CSS export writes `conic-gradient(from ...)`, with the stops mirrored
for a mirrored sweep.
- EPS and legacy .ai export write 360 solid wedges; the .ai editing data
holds a linear gradient along the vector with the same stops.
- .af files: conical gradients open as conic gradients.
- An export that writes the gradient in another form gives a warning.
Supersedes #2326 and includes switch87's code from it.

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.
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.
Docs: docs/mcp.md, docs/control-protocol.md, docs/target-app-parity.md,
object.setBounds params text.
The Measure and Measure & Inspect tools ignored View › Snap to Glyph:
their press and end points snapped only to targets that hold no glyph
guides.
With Snap to Glyph, Smart Guides and Alignment Guides on, and Snap to
Grid and Snap to Pixel off, a drag's press and end land within the
snapping tolerance on the guides of live type that the Character
panel's options allow, except Anchor Point. A Shift-drag's end slides
along its 45° step to them, and the guide shows during the drag. With
Snap to Glyph off, the tools snap to the same targets as before and
show no guide. The targets are kept while the document, the window and
the snapping options stay the same, so a drag lays out the type once.
Artboard Options gets a Global group with Fade Region Outside Artboard and
Update While Dragging. Both are application preferences
(fadeRegionOutsideArtboard, artboardUpdateWhileDragging), on by default and
also listed under Preferences > General > Artboard Options.
While the Artboard tool is active, the canvas draws the pasteboard with each
color channel at 60% of its value. With Update While Dragging off, the
pasteboard draws as usual while the tool moves or resizes an artboard and
darker again when the drag ends. Exports and print do not change.
Docs: docs/mcp.md, docs/target-app-parity.md.
The Eyedropper, the Live Paint check for paint to sample, the Appearance
panel's Characters chips and the colors the Libraries panel adds from
the selection found the paint behind the Fill or Stroke proxy through
Node::proxy_paint, which measures the object's geometric bounds. They
now read it with Node::proxy_paint_only.
- Eyedropper: the test for an empty fill reads the paint without
measuring. A sample measures the object only for a gradient or a
pattern, whose color depends on the point; a solid color gives its
color at once.
- Live Paint: the check for paint to sample reads the paint without
measuring.
- Appearance panel: the Characters row's two chips read the paint
without measuring.
- Libraries: adding a color or a pattern from the selection reads the
paint without measuring; a gradient is still measured for its
placement.
The paints and colors are the same as before. On an open path of
200,000 anchors, the Live Paint check and the Eyedropper's sample for a
point inside it take 0.004 ms together instead of 26.0 ms in a release
build.
Docs: docs/target-app-parity.md.
With Snap to Point alone, an anchor behind the start could pull the
projected end behind it, and the measurement read 180 degrees from the
pointer's step. Such an end is now turned back onto the pointer's step,
keeping its length, as an end rounded nearer another step is.
With a Constrain Angle other than 0, the grid point a Shift-drag's end
rounds to can lie nearer another 45-degree step, and the measurement then
reported that step. A Shift-drag from (0, 0) to (5, -3) with a 30-degree
Constrain Angle and a 9 pt grid measured -15 degrees instead of 30. The
end is now turned back onto the step nearest the pointer's direction,
keeping its length.
A drag that takes a selected freeform gradient point out of the object previews its removal,
which deselects it. A dropped press now selects again the point that was selected once the
tool took the press, and Escape reselects a point dragged out and back inside the object.
Escape also clears state that earlier clicks set up, so taking Escape for a
dropped press lost it in five tools. Each now drops only the press:
- Blend: the object picked first and the blend being added to are put
back as they were at the press.
- Dimension: a dropped click picks nothing, and the points or lines picked
before stay; a dropped drag is canceled as before.
- Width: the drag ends and the width points selected at the press are
selected again.
- Gradient: a dropped click on a freeform gradient leaves the line being
drawn open.
- Selection: with the pointer loaded with text, a dropped press threads
nothing and the text stays loaded; a dropped press on a port loads none.
The Measure tool and the Measure & Inspect tool snapped the end point of
a drag without Shift, but with Shift held they only turned the pointer
onto its 45° step and kept its distance: with Snap to Grid on the
measurement ended off the grid, with Smart Guides on it did not land in
line with an anchor, and with no snapping a drag of (37.3, 12.1) measured
39.2 pt at 0°.
Both now project the pointer onto the 45° step nearest its direction and
snap it there as the Line Segment tool snaps a Shift-drawn end, so it
stays on the step: (37.3, 12.1) measures 36 pt at 0° on a 9 pt grid, and
37.3 pt with no snapping. With Snap to Point alone, the anchor the pointer
snaps to is projected onto the step instead, so the end lands on an
anchor on the step and in line with one beside it.
A sample now shares one work limit, counted in objects looked at, across
hit tests, pattern tiles and the tile or symbol art it places for hit
testing, and gives no color when the limit runs out. Objects that give
no color are skipped by id instead of cloning the document for each
retry, each nesting level reuses one scratch document that holds only
the symbols, and patterns and images are looked up in the sampled
document. The sample runs on a deep stack and follows art inside art at
most 16 levels deep.
A symbol instance is now sampled as it draws: its art is stained by the
instance's fill and placed by the instance's transform without moving
the patterns in it or scaling its strokes. Between the shapes of its art
the sample shows what lies below instead of the stain, and a pattern
tile holding an instance is sampled wherever the symbol's art reaches.
Shift-click with the Eyedropper sampled solid colors, gradients and
images only; on a pattern fill or a gradient mesh it sampled nothing.
- A pattern gives the color of the front-most tile art at the point,
placed by the pattern's transform, at any tile size. Tile art that is
itself a gradient, image, mesh, symbol or pattern is sampled the same
way, and a pattern inside tile art moves with its tile. A gap between
the tile art gives the color of what lies below.
- A gradient mesh gives the patch color interpolated at the point.
- A symbol instance gives the color of its symbol's art at the point.
The Live Paint Bucket's Eyedropper sampling and Brush Options' Key Color
eyedropper use the same sampling.
With the Live Paint Bucket, Alt-click on vector art samples its fill,
stroke and stroke weight into the paint defaults, and on a placed image
it samples the pixel as a solid fill with no stroke. Alt+Shift-click
samples only the color under the pointer, including an intermediate
gradient color or image pixels, into the active fill or stroke. Neither
click paints or changes the selection or selected art, and the next
Bucket click paints with the sampled paint. While Alt is held, the
Bucket shows the Eyedropper cursor and no face or edge highlight.
appearance.copyFrom takes `defaultsOnly: true` to update only the paint
defaults, and paint.sampleColor takes `clearStroke: true` to clear the
stroke default after an image sample into the fill.
Holding backquote while dragging with the Selection tool (move, bounding-box
scale or rotate) or the Rotate, Reflect, Scale or Shear tool applies the drag
to the selected objects' pattern fills and strokes and leaves their geometry
in place. The key state at release decides the result: the key may be pressed
after the mouse button goes down, and releasing it before the button comes up
commits an ordinary transform. Objects without pattern paint do not move.
PointerEvent gains a `backquote` flag (false when absent). The desktop canvas
reads it from the held key on every pointer event, and `ui.pointer` and the
`pointer_gesture` tool accept it per event or as a default for the gesture.
Escape did not cancel a drag with the Anchor Point, Mesh, Shape Builder
and Measure tools, or a Direct Selection drag of a mesh point, a corner
widget or the brackets of type on a path: the drag went on until the
mouse was released. Escape cancels every other Direct Selection drag
and a drag with the Free Transform, Rotate, Reflect, Scale, Shear and
Gradient tools.
Escape now cancels an Anchor Point drag, a Mesh tool drag of a mesh
point or handle, and a Direct Selection drag of a mesh point or handle,
a corner widget or the brackets of type on a path. The art goes back to
how the press found it, no undo step is added, and the rest of the drag
and the release send nothing. Escape during a Shape Builder drag ends
it, so the release merges and deletes nothing; the tool takes Escape
only during the drag. Escape during a Measure tool drag ends it and
brings back the measurement shown before the press. Escape after an
Anchor Point or Direct Selection press that has not moved yet drops the
press. Otherwise, outside a drag, Escape does what it did before.

The Artboard Options help pages describe two display options
(https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/organize-manage-artboards/modify-display-settings-of-artboards.html,
.../set-video-display-options-for-artboards.html): a mark at the artboard's
center, and lines from the middle of each side through the center. The
document already had show_center_mark and show_cross_hairs on Artboard, but
nothing set or drew them.
artboard.setProps (each `artboards` entry too) and artboard.new take
showCenterMark and showCrossHairs as true/false, in the same single undo
step as the other fields; a locked artboard can still change them.
Artboard Options has both checkboxes, filled in from the artboard whether
it opens from the panel or a double-click with the Artboard tool, and its
New Artboard form passes them to artboard.new. The canvas draws them in the
new theme token artboard_mark, 1 point wide on screen at any zoom: a cross
12 points across at the center whose arms follow the artboard's sides, and
the two cross hairs. They are screen-only like the edges; exports and print
never read the fields. inspect_document reports them when on. Saved files
are unchanged: the two keys were already always written, so a document that
never shows them saves byte for byte as before, and a file without the keys
opens with both off. Video safe areas, video rulers and the pixel aspect
ratio are not part of this change.
Verification: artboard_display_marks_are_set_and_cleared_in_one_undo_step,
artboard_display_marks_round_trip_through_the_native_format,
artboard_display_marks_stay_out_of_exports (SVG and PDF identical with the
marks on and off), an_artboard_shows_its_center_mark_and_cross_hairs
(positions, screen-constant size under zoom, rotated view) and
artboard_options_show_center_mark_and_cross_hairs. cargo xtask ci: all 10
steps passed.
With the Artboard tool the arrow keys did nothing to the artboards: the
tool claimed only Escape, Delete and Backspace (tools/src/xform/artboard.rs
claims_key), so the arrows fell through to object.nudge in
ui-egui/src/shortcuts.rs, which moved the selected art on its own (or
nothing, with no art selected) and left the artboard where it was.
- artboard.rs: the tool claims the arrow keys and turns each press into
one artboard.move of the selected artboards that aren't locked, by the
keyboard increment (Preferences > General > Keyboard Increment, read
from the tool context as Touch Type does), Shift ten times as far as
object.nudge does, with moveArt from the tool's Move/Copy Artwork with
Artboard option, as a drag sends it. One undo step per press; nothing
during a drag or with only locked artboards selected.
- tests: arrow_keys_nudge_the_selected_artboards (tools: claims, step,
Shift, moveArt, several boards, locked, mid-drag) and
artboard_tool_arrow_keys_move_the_selected_artboards_with_their_art
(engine: the artboards and the art on them move, one step per press).
Verified live over --control: a 400x300 artboard with a selected 40 pt
square, Artboard tool, ArrowRight: before, the artboard stayed at x 0 and
the square moved to x 51 ("Move"); after, the artboard goes to x 1 and the
square with it ("Move Artboard"); Shift+Down moves both 10 pt; with
Move Artwork off only the artboard moves; increment 5 moves 5 pt.
The drag case in the report: a drag already moves the art, but only the
art that lies wholly inside the artboard and is unlocked and visible
(doc/src/lib.rs art_on_artboard; locked and hidden art only with
Move Locked and Hidden Artwork with Artboard). Art overlapping the
artboard's edge stays behind by design, which may be what the reporter
saw when dragging.
Hue Shift colorization can sample key color from canvas art via the
eyedropper next to the swatches, matching Illustrator's brush workflow.

With Use Preview Bounds on, the bounding box, the Transform panel,
Align, Distribute, Distribute Spacing and object.setBounds measured
each object without its geometry effects. A square with Offset Path
10 measured as the square, and type with Outline Object measured by
its layout box instead of its glyphs.
The new vectorcraft_effects::preview module measures objects as they
are drawn. A path is measured by its effected shape, with the
geometry effects of each fill and stroke that paints. Type, images,
live objects and symbol instances are measured by their reshaped art.
A group or layer with geometry or Pathfinder effects, or with a fill
or stroke of its own that has geometry effects or paints members with
geometry effects, is measured by its evaluated art. A blend, envelope
or repeat whose objects have geometry effects is measured by its
evaluated art, with those objects measured after their effects. Raster
effects are not measured. In one object, the art of at most 4,096 symbol
instances is measured with its geometry effects, and the other
instances are measured without them. With Use Preview Bounds off, the
measures are unchanged.
object.setBounds sizes objects with geometry effects by measuring
them after each scale it tries, so type with Outline Object set to
100 pt wide gets a glyph box 100 pt wide.
Selection::anchors_box is split out of Selection::anchor_bounds. The
doc comment of VectorcraftApp::selection_bounds said that it includes
effects; it now says that it leaves them out.
With the Artboard tool, a Shift-press on an artboard toggled it in the
selection and started a move, which Shift kept at 45° steps. A
Shift-drag on the pasteboard drew a square artboard. The reference
app's documentation gives Shift-drag inside an artboard as the way to
draw an artboard there, and Shift-drag on the canvas as a marquee that
selects artboards.
A Shift-click now toggles its artboard when the button comes up. A
Shift-drag inside an artboard draws a new artboard (artboard.new), and
a Shift-drag on the pasteboard toggles every artboard it touches, the
last one added becoming active. Shift no longer constrains an artboard
move or keeps a new artboard square, and no other modifier does. Shift
on the active artboard's handles still resizes it proportionally. The
hint bar names the Shift gestures in every complete catalog, and the
cursor is a crosshair over an artboard while Shift is held.
Escape while a new artboard was being drawn left the tool. Escape
during any drag, the new marquee included, now cancels the drag and
keeps the Artboard tool, as it already did during a move or a resize.
Docs: docs/target-app-parity.md.
A clip group answered a press only strictly inside its clipping path,
and there the art above the path came first in the hit test, so where
the clipped art extends past the mask's edge the clipping path's
segments could not be reached on the canvas.
With the new HitOptions::clip_outlines, which the Selection, Direct
Selection and Group Selection tools set
(ToolContext::selection_hit_options), a press within the selection
tolerance of a clipping path's outline, inside or just outside it,
hits the clipping path (HitKind::Outline) before the art it clips:
Direct Selection takes its segments and the Selection tool the clip
group. It applies to a clip group's clipping path and to a layer's
clipping mask, and only to one a click may hit (may_hit: visible,
editable, within reach). Inside the mask the art is hit as before.
The other tools, which act on what is drawn (the eyedropper, type,
gradients...), leave the option off, and hit_test_visible never
applies it, so they still take the art at the mask's edge rather
than the mask's empty appearance. Select Behind's one-pass walk takes
a layer mask's outline first too, so it lists what the repeated hit
test finds. Object Highlighting and a right-click's selection in the
canvas (selection_hit_at) take what those tools take; dropping a
swatch on art still hits what is drawn.
The reference app reshapes a clipping path with Direct Selection:
https://helpx.adobe.com/illustrator/desktop/manage-objects/edit-objects/edit-clipping-masks.html
Tests in doc: a_clipping_path_is_hit_on_its_outline_before_its_art,
only_the_selection_tools_hit_a_clipping_path_on_its_outline and
select_behind_takes_a_layer_masks_outline_first; the random Select
Behind test now clips layers and sublayers and sets clip_outlines,
and fails without the Select Behind change. In tools,
a_press_on_a_clipping_path_takes_its_segment_over_the_art fails
without the change; select::a_press_on_a_masks_edge_selects_its_clip_group
fails when the Selection tool uses the plain options; the eyedropper
copies the art on the edge. Recorded in docs/ui-parity.md,
docs/gaps.md and docs/target-app-parity.md.
