Every edit of an object copied its whole appearance (its fills, strokes and effects, about
540 bytes for a basic object) into the new node, though a move leaves it as it is. Over 45
whole-selection moves of 10,000 paths, undo history grew by 589 MB; now 349 MB (41 % less), and
a nudge or a drag of the selection takes 12 ms instead of 15.
- Node::appearance is a vectorcraft_doc::Shared<Appearance>: copy-on-write. A clone shares it,
and the first change through DerefMut copies it (Arc::make_mut). Reads, writes, equality (also
against a plain Appearance) and the saved form are those of the Appearance itself, so call
sites read and change it as before. Sites that build or assign a whole appearance add .into(),
and the few that need a plain copy take (*n.appearance).clone().
- Node::transform changes the appearance only when it has gradients to transform, and pattern
paints are transformed only when there are some: a move no longer copies an appearance it
doesn't change.
The workspace suite (5,301 tests) and clippy pass with the change; the doc and engine suites
pass again after the transform guard.

Double-clicking a Scatter, Art or Pattern brush in the Brushes panel (or the
panel menu's Brush Options...) now opens its options dialog, as Calligraphic
and Bristle brushes already did. OK runs brush.options and every stroke
painted with the brush redraws.
- Scatter Brush Options: Name; Size (10-1000 %), Spacing (10-10000 %),
Scatter (-1000-1000 %) and Rotation (-180-180 deg), each Fixed (the first
value), Random (between the two values) or Pressure (the first value at
the lightest pen pressure, the second at the heaviest); Rotation relative
to Page or Path. Scatter brushes now keep these modes (`modes`); brushes
saved before keep their look (Random where the two values differ).
- Art Brush Options: Name; Width (1-1000 %); Scale Proportionately, Stretch
to Fit Stroke Length or Stretch Between Guides with the guides' Start and
End (% of the art length); the four Directions; Flip Along and Across.
- Pattern Brush Options: Name; Scale (1-10000 %), Spacing (0-10000 %); the
five tiles (Outer Corner, Side, Inner Corner, Start, End) drawn with their
art or None; Flip Along and Across; Stretch to fit, Add space to fit or
Approximate path.
- All three: Colorization (None, Tints, Tints and Shades, Hue Shift with its
Key Color picked from the art's colours, the most used one by default) and
a live preview of a stroke painted with the edited brush.
Brush definitions from files and commands are now kept within these ranges
(Brush::sanitize, also for Calligraphic and Bristle values); unknown modes,
directions, fits or colorization methods are refused. The brush.options and
ui.brushOptions docs list the new params and fields. Tests: the brush model
(modes, pressure, sanitizing, art colours), engine params reaching the
brush and strokes redrawing, junk params in command_sweep, and headless
dialog tests for each dialog.

Double-clicking a brush in the Brushes panel (or the panel menu's Brush
Options…) opens its options. Calligraphic Brush Options: Angle,
Roundness and Size, each Fixed, Random or Pressure with its Variation,
over live previews of the nib and of a stroke. Bristle Brush Options:
Shape and the bristle sliders. OK runs brush.options; strokes painted
with the brush update.
The Paintbrush records the pen pressure along a stroke (path.freehand
takes [x, y, pressure] points), and a Calligraphic brush with Pressure
variation changes its nib along the stroke, from the value less the
variation at the lightest pressure to the value plus it at the heaviest.
Brushes saved before keep their Random variation. Pen pressure doesn't
reach the app on macOS yet (winit 0.30 reports none there).

A group's or layer's own fills and strokes paint every member's geometry, below or above the
members as the new contents slot (Appearance.contents_index) says; its geometry effects reshape
the members as one piece and its raster effects apply to the composite (one combined shadow),
respecting knockout groups. Type's own fills and strokes paint under or over its characters.
Render, SVG/PDF (via bake) and Expand Appearance evaluate them alike.
Commands: appearance.* / effect.* take target: "object"|"contents" and layer ids;
appearance.moveItem moves the Contents slot (from: "contents") or an item across it
(contents); appearance.targetContents selects a group's members. Graphic styles applied to a
group now style the group itself. The Appearance panel shows Contents/Characters rows that
drag, and double-click to target the members or edit the characters' paint.
