An appearance is basic with at most one fill and one stroke, none hidden or
with its own opacity, blend mode or effects, and no object effects; Reduce
to Basic keeps the topmost visible fill and stroke. The Layers panel fills
an object's target circle for any non-default transparency (blend mode,
isolation, knockout or an opacity mask: Node::has_default_transparency).
A multi-selection whose objects differ shows "Mixed Appearances" with no
rows. The Appearance panel's object row and the Control bar name the
selection from one source, and type objects are "Type". Expand Appearance
is only in the Object menu. Clear Appearance also resets the object's
opacity and blend mode. Tests cover addFill/addStroke, setItem/removeItem,
clear, reduceToBasic and graphicStyle.apply.

swatch.new takes mode and group; swatch.newGroup takes fromArtwork, toGlobal and includeTints and reports the group's swatches and the paints it linked. Adds a shared radio widget and the ui.newSwatch / ui.newColorGroup openers.

Clicking an Opacity row in the Appearance panel (a fill's or stroke's, or
the object's) opens a popup with the same blend-mode dropdown, opacity
field and slider as the Transparency panel (widgets::opacity_blend), and
edits that item through transparency.set. The blend-mode dropdown draws a
separator between the BlendMode::group() groups, also for the blend-mode
parameters of effect dialogs and inline effect editors. Fills and strokes
of type objects composite with their own opacity and blend mode.

Hollow heads draw as rings (the open arrow as a chevron) and closed paths get
no heads. The stroke stops under each head, so it never shows through a hollow
head or past the tip; stroke.set {arrowAlign: "extend"|"tip"} chooses whether
the tip extends past the end point (default) or sits on it with the stroke
shortened. Line and heads share one paint box (a gradient runs on into the
head) and take the stroke and object opacity once, as one layer on the canvas
and one group in PDF. StrokeLayer.arrow_align is a new defaulted field, so
older files load unchanged. The Stroke panel's Align buttons get two generated
icons and are disabled when the stroke has no head.

Arrowheads, width-profile outlines and dashed line outlines now come from
vectorcraft_effects::stroke (stroke_pieces, line_outline, width_outline), used by
the canvas and PDF export alike; the renderer caches profile outlines too. Width
profiles are a doc-level catalogue (WidthProfile::PRESETS, preset, preset_id,
id_of) shared by stroke.set and the Stroke panel; stroke.set rejects unknown
profile ids and its params doc lists the arrowhead names.

A dash pattern with a negative value (for example [-5, 3], from `stroke.set` or a PDF `d`
operator) was handed to the dasher whenever any value was positive. When the values sum to zero
or less the dasher never advances, so rendering the document hung forever (canvas, screenshot,
PNG/JPEG export, `vectorcraft-cli convert`).
PDF (32000-1 §8.4.3.6) and SVG (`stroke-dasharray`) both define such a pattern as invalid and the
stroke as solid. `Dash::is_dashed` now says whether a pattern draws dashes (finite, non-negative,
not all zero), and the renderer, the width-profile outline, the SVG and PDF exporters and the PDF
importer use it, so an invalid pattern is drawn, written and read back as a solid stroke everywhere
(the PDF exporter used to clamp negatives to 0, writing zero-length dashes).

Clicking a fill or stroke row runs appearance.setActiveItem; the toolbar,
Control bar and Properties proxies and the Color, Swatches, Gradient,
Stroke and Transparency panels show and edit that item, and the gradient
tool's annotator follows it. paint.setFill/setStroke, stroke.set/
setAdvanced, paint.editGradient/setGradientGeom and transparency.set take
item (omitted: the active item, null: the top one). Item edits and the
appearance.* commands address the selected objects' own stacks, so a
group's own fills no longer leak into its contents. Any selection change
clears the active item.

Document::swatches_iter/_mut, swatch_mut, swatch_group_of, remove_swatch and a copy-on-write
walk over linked solid paints (map_solid_paints) cover every colour group.
