One rule for the hover's context (PR review follow-ups): the target is
recomputed where the pointer is, or cleared, whenever what lies under it
can change while Alt is held.
- The tool hovers only where the pointer is on the canvas itself
(`on_canvas`): under a floating panel, a menu, a popup or a dialog
its hover ends (Tool::hover_ended), as when the pointer leaves the
canvas or a pan, zoom or view-rotation press starts.
- The canvas keeps the hover's context: its rect, the view's centre,
zoom and rotation, and the active document's id and revision (which
moves with every edit, undo and selection change). When it changes
under a still pointer, a tool that asks (Tool::wants_rehover; the
Selection tool after an Alt hover) is hovered again at the pointer,
so wheel, gesture, key or command scrolling and zooming, tab
switches, edits and undos re-measure.
- Coming back onto the canvas re-hovers the tool.
canvas::tests::distance_guides_follow_what_lies_under_a_still_pointer:
a floating window over the pointer (fails without the on_canvas filter),
a 150 pt scroll that leaves empty artboard under it (fails without the
re-hover), a square made under it. select::tests::distance_guides_need_
alt_a_selection_and_smart_guides checks wants_rehover.
An Alt+Space pan press went to Drag::Pan and never reached the tool, so the Distance Guides stayed through the pan until the pointer left the canvas (PR review follow-up). One rule now covers all three cases: the tool's hover ends (Tool::hover_ended, renamed from pointer_left; Session::tool_hover_ended) when the pointer leaves the canvas with no press the tool holds, and when a press starts any drag that doesn't reach the tool (pan, middle-button pan, zoom box or scrub, view rotation, touch gesture). canvas::tests::distance_guides_go_when_the_hover_ends asserts they go at an Alt+Space press and stay gone panning out over a panel.
The pointer-left check skipped every drag, so Alt+Space panning out over a panel kept the measurements (PR review follow-up). Only a press the tool holds (Drag::Tool, Drag::Art) keeps its state now; pan, zoom box, zoom scrub, view rotation, gesture and presentation drags never reach the tool. canvas::tests::distance_guides_go_when_the_pointer_leaves_the_canvas pans out with Alt+Space; it fails with the old drag.is_none() check.
Leaving the canvas (for a panel, or out of the window) sent the tool no
hover event, so the Selection tool kept its Alt-hover target and went
on drawing the measurements (PR review finding).
- Tool::pointer_left: the pointer left the canvas with no button held;
the Selection tool drops its Distance Guides target and its Smart
Guides hover label. Session::tool_pointer_left reaches it.
- The canvas remembers whether the pointer was over it last frame: on
leaving with no drag it calls tool_pointer_left; on coming back it
re-hovers the tool even after a single jump egui doesn't count as
moving, so the guides show again.
Tests: canvas::tests::distance_guides_go_when_the_pointer_leaves_the_
canvas (fails before: the label stayed over a panel with Alt held),
select::tests::distance_guides_need_alt_a_selection_and_smart_guides
(pointer_left clears them).
Distance Guides, from the public "Use Distance Guides for accurate
placement" and "Smart Guides options" (Invoke Distance Guides) pages:
with Smart Guides on, something selected and the Selection tool,
holding Alt/Option over another object shows the horizontal and
vertical distances between the selection and it, and over an empty
part of an artboard the selection's distances from the artboard's left,
right, top and bottom edges.
- guides::distance_guides measures the selection's bounds to a box: on
an axis on which they lie apart, the gap between their facing edges;
otherwise the offsets of both pairs of matching edges. Each line runs
across the middle of the overlap on the other axis (else the
selection's middle), with a dashed line out to the target's edge when
it passes beside it. An artboard is always measured edge to edge.
Labels are in the General unit, in the smart guide colour.
- The Selection tool keeps what its Alt hover points at and draws the
guides while idle; letting Alt go (the canvas re-hovers on a modifier
change), a press or moving off clears them.
- Overlay::Distance: the line with end ticks and its length in a pill;
the canvas draws it.
- Preferences › Smart Guides › Invoke Distance Guides (`distanceGuides`,
on by default), with i18n rows; View › Smart Guides gates it too.
- Hover only, as the pages describe: nothing while moving or nudging.

Step 3 of the Rectangular Grid tool and Arc tool help pages
(https://helpx.adobe.com/illustrator/using/tool-techniques/rectangular-grid-tool.html,
https://helpx.adobe.com/illustrator/using/tool-techniques/arc-tool.html)
and the Tools page (https://helpx.adobe.com/illustrator/using/tools.html)
say a double-click on the tool opens its Tool Options. For these four tools
the double-click (tool.options, and Enter once #2891 lands) said the tool
had no options (#2691).
The Tool Options are the tool's click dialog in dialogs/shapes.rs, opened
without a place to draw (shapes::open_options; a `__toolOptions` field
marks it), as the review of #2979 asked: no copied form code. Its OK runs
tool.setOption and draws nothing; Cancel changes nothing. The grids' dialogs
are titled Rectangular Grid / Polar Grid Tool Options there. The options
are what the next drag draws with and what a click's dialog opens at:
- Line Segment: Length and Angle (now kept by the tool and used by the
click dialog) and Fill Line (new: shape.line {fill: true} gives the line
the current fill; the click dialog has it too);
- Arc: lengths, Reference Point, Type, Base Along, Slope, Fill Arc;
- the grids: dividers, skews and switches, plus the Default Size and
Reference Point, now kept by the tool (width, height, reference) for the
click dialog; a drag leaves them out of its command.
The grids' Reference Point is drawn only as the 9-point locator (it also
showed as a plain number field).
New strings (Rectangular Grid Tool Options, Polar Grid Tool Options, Fill
Line) have rows in all 24 catalogs.
Verification:
toolbar::tests::double_clicking_the_line_arc_and_grid_tools_opens_their_tool_options
double-clicks each tool's toolbar button: the dialog and its title, Cancel
leaves the next drag as it was, OK draws nothing, the next drag uses the
option and a click's dialog opens at it (a grid at its Default Size);
line_segment_options_and_fill_line, grid_default_size_is_an_option_the_drag_leaves_out,
fill_line_gives_a_new_line_the_current_fill. Grid dialog tests now expect
the stored Default Size. Live: double-clicking the Rectangular Grid tool in
the release build opens Rectangular Grid Tool Options; OK with 2 and 3
dividers, then a drag, draws a 3 × 4 grid.
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

artboard_options_show_center_mark_and_cross_hairs. cargo xtask ci: all 10
steps passed.
A Shape Builder drag merged only the regions the pointer passed over,
and the tool did not read Shift. The reference app's Shape Builder page
describes a Shift-drag that draws a rectangular marquee to merge many
paths at once.
With Shift held at the press, the drag now draws a rectangular marquee
from where it started to the pointer. The regions it reaches are shaded
while it is drawn and merge into one shape on release; with Alt also
held at the press, they are deleted. The marquee reaches each region
whose outline crosses it or has an anchor inside it, and the region that
holds the whole marquee. A Shift-click that does not move is a click,
and a drag without Shift works as before. With In Merge Mode, Clicking
Stroke Splits the Path on, a Shift-click on a stroke splits it as a
click does; a marquee splits no stroke, and while it is drawn the
pointer does not show scissors and no stroke is highlighted.
shapeBuilder.merge takes the marquee as rect: [x, y, width, height],
where x and y are where the drag started, and points may then be left
out. For Pick Color From Artwork, the corner where the drag started
counts as the drag's first point, and the opposite corner counts as its
last. With rect, splitStroke does not split a stroke.
Docs: docs/mcp.md, docs/target-app-parity.md.
Cause: with Snap to Point, the point of a moved selection that snaps to a
ruler guide is the grabbed point (#1534). Away from an anchor or center
that was the raw pressed spot (select.rs: `grab` fell back to `p`;
direct.rs: a straight segment's `grab: p`, MoveObject's `start`). A press
on a stroke or within the pick tolerance of an edge lies a few pixels
beside the path, so the pressed spot landed on the guide, "align" showed,
and the path stopped that far beside it: 0.096 pt at 3,891% and 0.0099 pt
at 28,757% in the #3701 screenshots, visible only when zoomed in.
Change: `guides::hold_on_path` finds the nearest point of the path (on a
straight segment exactly on its line). `select::hold_point` uses it for a
press on the stroke or outline, or within 6 px of it. The Selection tool
(`State::Moving::hold`), Direct and Group Selection moves
(`State::MoveObject::hold`) and Direct Selection's straight-segment drag
(`grab`) snap that point. The move delta still runs from the press, so
nothing jumps. A press in the middle of a fill still snaps the pressed
spot, as Snap to Point is documented to.
Verification: tests_prefs::a_move_held_by_a_paths_stroke_lands_the_path_on_a_ruler_guide
and tests_prefs::a_straight_segment_dragged_by_direct_selection_lands_on_a_ruler_guide
fail without the change (edge 0.0257 pt and anchors -0.0052 pt off the
guide) and pass with it (|gap| < 1e-9 pt). A headless egui/wgpu render at
3,891% and 28,757% puts the guide, the selection outline and the centre of
the 1 pt stroke band in the same pixel column. cargo xtask ci: all 10
steps passed; 9429 tests passed, 0 failed.
With In Merge Mode, Clicking Stroke Splits the Path on, the run a click
split off could run against its path. A click on a rectangle's top side
gave a side from (100, 0) to (0, 0) on a rectangle that runs from
(0, 0) to (100, 0) there, so arrowheads and other settings that follow
a stroke's direction moved to the other end. The run now goes the way
the path goes.
The two paths of a split, and what an Alt-click or a merge leaves of a
path, had a gradient fitted to the path's bounds fitted again to their
own bounds. They now keep it where it was on the path.
A run that left 0.05 pt or less of a path still split it, into the
run and a speck. Such a path now does not split, and the tool shows
no scissors over it.

Illustrator 30.0's Method choice in the Gradient panel
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-perceptual-interpolation-in-gradients.html).
- paint.editGradient takes `method: classic|perceptual` (one undo step);
paint.setFill/setStroke take it in `gradient`, and gradient params (swatches,
copied paints) carry it when Perceptual. Anything else is refused without
editing. One edit can set `method` and `dither` together.
- The Gradient panel shows a Method menu (Classic, Perceptual) for linear and
radial gradients, dimmed without a gradient; the Dither box stays under the
stops.
- i18n: "Perceptual" where a complete catalog lacked it, and the `method`
error in all 24 catalogs.
- Docs: G13 (estimate 14–24 h → 13–23 h, after Dither's 15–25 h → 14–24 h),
target-app-parity (row and evidence), ui-parity, mcp.md, plugins.md.
With Pick Color From Artwork, a Shape Builder merge took the look of
the front-most object over the first covered region the drag touched,
and the current fill when the drag touched only areas no object
covers. The reference app's combine page gives the look of the object
where the drag starts, else of the object where it ends, else of the
topmost selected object.
shapeBuilder.merge now follows that rule: the merged shape takes the
appearance, opacity and blending mode of the front-most of the objects
it is given (the selection by default) under the first point, else of
the one under the last point, else of the front-most of those objects.
A drag from a hole across a gray bar into a red square now gives a red
shape, where it gave the bar's look. A click in an area no selected
object covers, such as a hole that gray bars enclose or a triangle
that lines enclose, takes the front-most selected object's look
instead of the current fill. Pick Color From Color Swatches works as
before. The tool already sends the press point first and the release
point last.
Docs: docs/mcp.md, docs/target-app-parity.md.
Illustrator 30.0's gradient Dither, from the public documentation
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-dither-in-gradients.html):
a Dither checkbox in the Gradient panel; dither converts the gradient into
pixels with subtle noise, works with gradient fills only, and follows the
Document Raster Effects resolution.
- Gradient gains `dither` (serde default false, written only when on, so
older files open unchanged and new files keep it).
- The renderer draws a dithered linear or radial fill as an image paint: the
gradient sampled a cell per device pixel or finer (quarter-octave steps,
cached per thread), each channel given seeded triangular noise of up to a
level before rounding. Same pixels every run; strokes and undithered fills
draw exactly as before. PNG and other raster exports go through it.
- SVG and PDF write a dithered fill as an image at the document's raster
effects resolution, clipped to the shape (the freeform-gradient path);
characters' fills stay vector gradients in SVG, with a warning.
- paint.editGradient and paint.setFill take `dither`; strokes refuse it.
The Gradient panel's Dither box is dimmed behind the Stroke proxy.
- i18n rows in all 24 catalogs; docs: G13, target-app-parity, ui-parity,
mcp.md, plugins.md.
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.
## Summary
Adobe help documents Area Type and Type on a Path as starting from a click on the path or shape border, not inside a filled interior. Restore outline-only hit testing for those tools (no fill-interior hits that would steal point-type clicks). Strokeless filled paths still accept clicks on the outline.

## Summary
Area Type and Type on a Path locate the path under the click with the same hit rules as the other tools, so a filled shape with no stroke can be clicked in its interior. Illustrator accepts those clicks for area type and for type on a path (the start follows the click on the path). VectorCraft had forced outline-only hit testing here, so interior clicks missed and the tools fell back to ordinary point or area text with placeholder copy.

A face hidden on its own (for example with Object > Hide after Live
Paint Selection picks it) while its Live Paint group stays visible was
still highlighted, selected by Live Paint Selection and filled by the
Live Paint Bucket, and it kept the face of a group behind it from being
picked.
live_paint_at and lp_part_at now take the front-most face that is not
hidden (visible_face_at). A point on a hidden face falls through to the
visible face of a group behind it; where there is none, an edge pick
takes the nearest visible edge as it does outside the faces.
livePaint.fill also skips hidden faces. With group, a point on a hidden
face is an error. With ids, it fills the face there of another Live
Paint group among the objects, or else fails and does not merge the
group.

Hue Shift colorization can sample key color from canvas art via the
eyedropper next to the swatches, matching Illustrator's brush workflow.
Co-authored-by: Cursor <cursoragent@cursor.com>
Illustrator links type in an area or along a path (https://helpx.adobe.com/illustrator/using/manage-text-area.html); until now only area type threaded here. Type on a path that overflows ends its line where its text stops fitting, so a story flows on from it, and its red out port, just past its end bracket, loads the Selection tool with the text as area type's does. A new frame threaded from it at a point is type on a path of its shape.
With Use Preview Bounds on, a bounding-box handle drag scaled the art by
the ratio of the visual box, so margins that stay (a stroke with Scale
Strokes & Effects off, an Offset Path reach) or scale by another factor
moved the opposite visible edge: dragging the right edge of a square with
Offset Path 10 from 210 to 310 left its left edge at 98.33 instead of 90.
The Selection tool now previews object.setBounds with the dragged visual
size and the opposite handle (with Alt, the center) as the reference
point, so the scale is solved from the geometric box and the margins the
visual box adds, for strokes with Scale Strokes & Effects on or off and
for geometry effects. Shift and Alt drags follow the same rule; a drag
that flips the box, and one with anchors selected, still scale by the
matrix. A previewed object.setBounds runs as object.transform with the
transform it finds, so Transform Again repeats the drag and the journal
holds that transform. The drag transforms a path of a compound path
selected on its own, as object.transform does, and leaves the art at
least 1e-4 of its width and height.
With Use Preview Bounds on, every hover frame's cursor and every
pointer move measured the selection again, and with Smart Guides on
each selected object too, evaluating their geometry effects each time.
The session now keeps a PreviewMemo, which ToolContext::preview_memo
passes to the tools. selection_bounds, selection_box and the object
bounds that Smart Guides find centers in while hovering read it. The
memo holds the measurements for one key: the document's uid and
revision, the selected objects and Use Preview Bounds. A new key
replaces them. VectorcraftApp::selection_box in the UI keys on the
uid, the revision and Use Preview Bounds. A ToolContext without a
memo measures on every call.
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.
Double-clicking the Shape Builder tool reported that the tool has no
options. The reference app opens Shape Builder Tool Options there.
The dialog sets Consider Open Filled Paths as Closed, Pick Color From
(Artwork or Color Swatches), Cursor Swatch Preview, Selection (Freeform
or Straight Line) and Highlight Fill. The defaults keep today's
behavior. With Consider Open Filled Paths as Closed off, a filled open
path cuts regions as an unfilled one does. With Color Swatches, a merge
fills the new shape with the current fill, and the Left and Right arrow
keys step the current fill through the document's color swatches.
Cursor Swatch Preview shows the current fill and the swatches before
and after it above the pointer. With Straight Line, a drag merges what
the line from its first point to its last crosses. With Highlight Fill
off, merge mode shades no regions.
The options persist like other tools' options. shapeBuilder.merge
takes openFilledAsClosed and pickColorFrom, and shapeBuilder.regions
takes openFilledAsClosed. Gap Detection, "In Merge Mode, Clicking
Stroke Splits the Path" and Highlight Stroke When Editable are not part
of this change.

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.
Holding Alt while drawing with the Paintbrush, or with the Pencil while
Alt key toggles to Smooth Tool is off, closes the path at the release,
but the cursor did not change. The reference app's Paintbrush shows a
small loop while Alt is held, and its Pencil shows a small circle.
Cursor::PaintbrushClose and Cursor::PencilClose show while Alt is held
with the Paintbrush, and with the Pencil while that option is off,
before the press and while drawing. Both tools still borrow the
crosshair, so the closing cursors are drawn as that crosshair with the
PenClose ring. Use Precise Cursors turns them into the plain crosshair,
as it does PenClose.
With Alt key toggles to Smooth Tool on, the Pencil shows the Smooth
cursor while Alt would smooth: with Alt held before a stroke begins to
draw, and through a smoothing drag even after Alt is let go. Before, it
showed the Smooth cursor whenever Alt was held, also during a stroke
that kept drawing, and not during a smoothing drag once Alt was let go.

With View › Snap to Grid on, a whole object moved with the Selection,
Group Selection or Direct Selection tool landed on the grid by
whichever of its two edges or its center was nearest a gridline on
each axis. An object on the grid whose width is an odd number of grid
steps has its center half a step between gridlines, so a short drag
could pull it half a step off the grid: on a 20 pt grid, a 100 pt
square at (100, 100) dragged by (8, 8) moved by (10, 10).
A move now lands the nearer of the two edges on a gridline on each
axis, as the reference app's help describes, and the center no longer
snaps. The square above stays at (100, 100). This changes the rule #769
chose for #740. The plain move and the Shift-constrained one both use
grid_pull, so both change.
Docs: docs/target-app-parity.md (Drawing aids).
A Blob Brush stroke followed the pointer whatever modifier keys were
held. The reference app's shortcut list has Shift constrain the Blob
Brush path horizontally or vertically.
With Shift held during a drag, each point of a Blob Brush stroke now
goes on the horizontal or vertical line through the press point that
is nearer in angle to the pointer, at 90-degree steps from the
Constrain Angle preference, and keeps its distance from the press
point. When the pointer crosses to the other line, the points dragged
since Shift went down move to it, each on its own side of the press
point. Each point reads the Shift state of its own event, so the
points dragged while Shift is up follow the pointer. The stroke still
runs path.blob once on release.
Docs: docs/target-app-parity.md.
object.objectsOnPath.attach took a path inside a compound path, blend,
envelope, repeat or Intertwine group, or a clipping path, as the path
and put it into the new Objects on Path group, so it was no longer a
part of its container. As objects, a blend's key path, a repeat's
source art, an envelope's content and a clipping path were put into
the new group the same way.
The Objects on Path tool highlighted a blend's key path or a clipping
path and attached the selection to it.
objects_on_path::held now finds the container that holds an object.
The command refuses such a path or object with a reason, and the tool
does not highlight it or attach to it. A member of a compound path
given as an object still attaches as its whole compound path. The four
new messages have rows in every complete-message catalog.

An edge hidden on its own (for example with Object > Hide) while its
Live Paint group stays visible could still be highlighted, selected or
stroked, and a hidden edge nearer the pointer kept a visible one from
being picked.
lp_part_at now takes the nearest visible edge (visible_edge_near), inside
and outside the faces, for the hover, the Live Paint Selection click and
the Bucket's Shift-click. The Bucket's Shift-click sends nothing where no
edge is highlighted, and livePaint.strokeEdge also skips hidden edges, so
the Bucket strokes the edge it highlights.
With Select Fills off, or with Alt held, the Live Paint Selection tool
highlighted an edge near the pointer even when the pointer was outside
every face, but a click there looked only for a face under the pointer
and cleared the selection. Outside the faces, the highlight came from
the front-most Live Paint group with an edge in reach, not from the
nearest edge, and it included hidden groups. The Live Paint Bucket's
Shift highlight and Shift-click used the same search.
The hover, the Live Paint Selection click and the Bucket's Shift-click
now call one function. Outside every face it picks the edge nearest
the pointer, within 4 screen pixels, among the visible Live Paint
groups. A click selects or strokes the edge that the highlight shows.
