With several objects selected whose appearances differ in anything (two
circles whose fills differ but whose stroke and effect are the same),
the Appearance panel showed only "Mixed Appearances": no stroke, effect
or opacity row, so attributes the objects share couldn't be edited
together. It now lists what they share, as the issue describes:
- `vectorcraft_doc::appearance::SharedStack` (with `align`, a stacking-
order longest-common-subsequence match) gives the fills, strokes and
object-level effects every object has an equal copy of, and where each
is in every object's own stack.
- The panel's object row names the objects' common kind ("Path",
"Ellipse"; "Mixed Objects" only when kinds differ, as the Control bar
does), with an italic "Mixed Appearances" row under it when they
differ, then only the shared rows with their usual controls. The
Opacity row reads "Mixed" when opacity or blend mode differ (an edit
sets them all). The object row shows no fill chip when the fills
differ. Rows aren't dragged in a mixed selection: where a row would go
in each of several different stacks isn't one place.
- The engine maps a shared row to each object's own item: the active
item (a row of the first selected object's stack) always does, so the
Color, Stroke and Transparency panels edit every object's matching
item, and the item and effect commands do with `aligned: true`
(appearance.setItem / removeItem / duplicateItem, effect.remove /
duplicate / setParams / lightingPreset, transparency.set), each as
one undo step. moveItem and effect.move refuse aligned rows of
differing stacks. Without `aligned`, explicit indices keep their
meaning for single objects and scripts.
- "Mixed" is added to every catalog.
Tests: the shared stack of the issue's case, of a stroke at another
index, of nothing alike and of equal stacks, and that matches never
cross; editing the shared stroke edits both strokes (at index 1 and 2)
in one undo step that restores both, also through stroke.set on the
active row; removing a shared effect and adding a fill reach both, and
reordering differing stacks is refused; the panel lists kind, note,
Stroke, Feather and Opacity, not Fill, the full stack for alike objects
and "Mixed Objects" for a path and type. The existing object-row test
now expects the kind for two rectangles and the shared rows when their
opacity differs.
