Knockout Group is now Knockout {Neutral, Off, On} (old files' true loads as
On, false as Neutral). In a knockout group each child erases what the
children below it drew where it paints, then adds itself, so it composites
against the group's backdrop; neutral plain groups pass their children
through to the enclosing knockout group. transparency.set / object.setProps
take knockout "on"|"off"|"neutral"|bool; transparency.info reports the
state. PDF and SVG write knockout groups as nested soft masks with the same
look (PDF warns); the Transparency panel has a tri-state checkbox.

A group's own stack now stays empty after Clear (and keeps only the rows it had after Reduce to
Basic), so the proxies keep showing the defaults for it. The Layers target-dot helper no longer
takes over the thumbnail function's doc comment.

- A fill row no longer turns stroke edits (stroke.set, setAdvanced, paint.setStroke, gradients) into
a new stroke on a selected group's own stack: an active row only stands for edits of its kind.
- Removing, duplicating or moving items of other objects (`ids`) no longer re-points the active row.
- transparency.set with an item touches the item only for opacity/blend (isolate or knockout alone
is one undo step) and rejects unknown blend modes.

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.

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.

effect.apply, effect.remove, effect.setParams and the new effect.duplicate
take item (omitted: the Appearance panel's active item, else the object;
null: the object's own effects), so the fx button, the Effect menu, Apply
Last Effect and the effect dialogs (effect.dialog {item}) put the effect on
the selected fill or stroke. effect.list reports each object's item effects
and the active item. appearance.addEffect is an alias of effect.apply.
In the Appearance panel, item effect rows sit under their fill or stroke
with working eyes and inline editors, and can be selected for Duplicate
and Delete; a selected effect row is remembered per object.

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.
