Symbol editing copies the editing layer's art into the symbol before Text Wrap, list numbering and threaded re-flow update that layer, so moving a wrap object in the edit left the symbol, its other instances and the saved file with the old wrap. The edit now syncs the symbol again after those passes, and when that changes the symbol, inline graphics of it are refreshed and the threads holding them re-flow.
- In `shaper::refresh`, replace full document walks with `changed_shaper_groups`,
diffing `before` and `after` layers and short-circuiting on pointer-equal (`Arc::ptr_eq`)
subtrees in O(1).
- Return whether Shaper groups rebuilt or modified artwork (`Result<bool>`),
allowing `Session::edit` to skip the second `cmd::objects_on_path::refresh`
call when no artwork was modified.
- In `textwrap::refresh`, check pointer equality on layers against `before.layers`,
skipping untouched layers in O(1) and checking only modified layers.
A Shape Builder click or drag over a selection of more than 128
segments merged on the UI thread, so the app stopped drawing and
answering until the merge was done. The tool now computes such a
merge on another thread from the map it built for the hover.
Meanwhile the canvas keeps drawing, the touched regions stay
highlighted and the pointer is the busy pointer. When the merge is
done, the tool runs shapeBuilder.merge with the gesture's params as
one undo step, and the command takes the computed shapes when it
would compute the same ones. The web build merges in the command, as
before.
A press while the map is still being built no longer waits for it on
the UI thread: the tool records the gesture and makes it once the map
is there.
Clicks, drags and the Shape Builder's arrow keys made during the
merge, and commands, menu items, the app's own dialogs, saves and tool
or document switches, run after it on the merged art; engine queries
that only read run at once. A change to the selected paths made
outside a command drops the merge. The headless host and ui.pointer
reply once the merge is applied.
The Shape Builder and the Live Paint Bucket keep their map of the
selection over a new revision of the document when the selected paths
and their outlines are unchanged, instead of building it again.
