Commands that read the selection through edit::selected_roots leave
out an object whose group is also selected (edit::roots_of). Fourteen
places that read `ids` kept an object listed together with its group.
Given ids that list an object and a group that holds it, Make Repeat
failed with "no such object", New Symbol failed or stored the object
twice in the symbol, and object.transform moved it twice (20 pt for a
10 pt move).
These places now pass explicit ids through edit::outermost, which
drops an id whose ancestor is also listed, with the filter that
roots_of runs on the selection (now edit::without_inner). Nothing else
is dropped or replaced: unlike roots_of, it keeps layers and
compound-path members. A list without nesting gives the same result as
before. Commands that take both ids and the selection as listed, such
as paint.setFill without item, are unchanged.

On each pointer move of an Alt-drag with the Perspective Selection
tool, Session::preview put the drag's snapshot back and ran
perspective.move with copy again, and persp_edit copied every selected
object again. An Alt-drag of a plane widget with the Perspective Grid
or Perspective Selection tool ran perspective.plane.move with objects
"copy" again, and plane_move copied every object on the plane again.
Both commands now take their copies from preview_copies, as
apply_transform does for the Selection and transform tools: the first
preview copies the objects into a clone of the snapshot, and each later
preview of the same objects on the same snapshot maps only those
copies. The copies keep their ids, and the document, the selection,
the undo step and the journal are the same as before. When the stored
grid still lists attachments of its own, as grids saved before
attachments were kept on the objects do, both commands copy on every
preview as before. With 25,000 rectangles attached to the left plane,
a release build of vectorcraft-cli took a median of 424.8 ms for each
Alt-drag move of the objects after the first preview and takes
328.9 ms with this change. An Alt-drag of the plane's widget took
340.3 ms a move and takes 256.9 ms.

Lock › All Artwork Above and Hide › All Artwork Above went through the
objects above each selected object in its top-level layer, one selected
object at a time. For each object they looked up in a list whether it
was selected or already found, and they computed its bounds again for
each selected object below it until one overlapped it. With 100 tiles
selected under 25,000 rectangles, a release build of vectorcraft-cli
took 6.4 s for Lock, and with all of 5,001 objects selected it took
8.8 s and locked nothing.
The commands now go through each top-level layer that holds a selected
object once, and check each object that is not selected against the
bounds of the selected objects below it. The selected objects and the
objects found are kept in sets, and each object's bounds are computed
once. The objects they lock or hide, the count, the selection and the
undo step are the same as before. On the same documents Lock now takes
under 0.1 s.

Offset Path, Outline Stroke, the Pathfinder panel, Clean Up, Make
Blend, Rasterize and the other commands that #1429's table marks 3,
except Split Into Grid, added, removed or replaced their objects one at
a time, and so did Remove Anchor Points, Redefine Symbol and the
removal of Shaper groups whose source art is gone. Each insertion or
removal moved the later objects of the layer or group. The lookups by
id that followed walked the tree, and every fourth walk rebuilt the
lookup cache. On 25,000 rectangles a release build of vectorcraft-cli
took 29.1 s for Offset Path.
These commands now make their edits with Document::wrap,
Document::insert_beside and Document::remove_many, in one pass over the
children of each layer or group, and Outline Stroke and Expand write
each new object into the place of the object it replaces. A list that
holds an object twice, or an object and another inside it, and that was
edited without an error before, is still edited one object at a time.
The documents, selections and undo steps are the same. On the same
rectangles Offset Path now takes 1.3 s.

These commands removed, moved or copied one row or object at a time:
the Layers panel's Delete Selection, Duplicate Selection, Collect in
New Layer, row drags, Merge Selected, Flatten Artwork and Release to
Layers, and Cut Artboard, Duplicate Artboard and the Artboard tool's
Alt-drags that copy art. Each edit moved the later rows of the same
layer or group to other indices. The next lookup by id then walked the
tree, and after every fourth such walk Document::index_path rebuilt
the whole lookup cache. Release to Layers also walked the document
twice for each new layer to name and color it. With 25,000 rectangles
in one layer, a release build of vectorcraft-cli took 11.9 s for
Duplicate Selection and 17.7 s for Release to Layers.
The commands now remove, move and copy the rows in one pass over each
layer or group, with Document::remove_many and Document::wrap, and
with copy_above, the copy pass of duplicate_in, which Duplicate
Selection and the artboard copies now share. Release to Layers names
its new layers from one walk of the document. Merge Selected checks
the target layer's objects against a set of the listed rows, and
Delete Selection checks the top-level layers against such a set. In a
document whose ids are unique, the rows keep their order, new rows and
layers take the same ids, names and colors, and the selection, the
undo step and the journal are the same. A release build with this
change takes 98 ms for Duplicate Selection and 26 ms for Release to
Layers.

Delete, Cut, Group, Make Compound Path, Make Clipping Mask, Send to
Current Layer, Ungroup and Release Compound Path removed, inserted or
moved one object at a time. duplicate_in inserted one copy at a time;
Duplicate, Copy in the Move, Rotate, Scale, Reflect and Shear dialogs,
Transform Again after a copy, Transform Each with Copy, the perspective
copies and each move of an Alt-drag call it. Each insertion or removal
moved the later objects of the same layer or group to other indices.
The next lookup by id then walked the tree, and after every fourth such
walk Document::index_path rebuilt the whole lookup cache. Each command
did work that grew with the number of objects times the size of the
document: with 25,000 rectangles selected, a release build of
vectorcraft-cli took 7.2 s to group them and 11.5 s to copy them with
object.transform.
Document::remove_many, Document::wrap and Document::insert_beside
remove nodes, wrap them in a new node, or put nodes directly above or
in place of their anchors, in one pass over the children of each
parent. Each finds the nodes with one index_paths call, checks every id
before it changes anything, and clears the lookup cache once. The
commands above use them. The objects keep their order, the copies take
their ids in the same order, and the selection, the undo step and the
journal are the same. duplicate_in still copies one root at a time when
a root is listed twice or lies inside another root. A release build
with this change groups the 25,000 rectangles in 27 ms and copies them
in 121 ms.
