Commands that read `id` and otherwise act on the selection, the highlighted
layer row or a new object read it with a lenient helper, so `{"id": "abc"}`,
`true` or `{}` acted on the selection instead. They now read it with
`object_param`, which refuses any value that is not a non-negative integer
with "`id` must be a whole number" under the command's name and changes
nothing; an omitted or null `id` keeps the default.
Commands: object.isolate, layer.locate, layer.releaseToLayers,
graphicStyle.new and redefine, charStyle and paraStyle new, apply and
redefine, image.info, links.info, links.goTo, links.unembed, shaper.release,
shaper.expand (whose errors now carry their own name),
transparency.editOpacityMask, transparency.viewOpacityMask, symbol.edit, the
object.blend.spine commands, path.curvature and the type commands that read
type ranges.
The Join tool drew a segment between the open ends of two crossing paths
instead of trimming what overhangs the crossing. path.joinScrub now looks for
two crossing open subpaths whose overhanging ends the scrub runs over, cuts
both at the crossing and joins the kept parts there with a corner, in one undo
step. Without a crossing the endpoint join is unchanged.
Drawing a new Pencil or Paintbrush stroke kept the earlier selection: the engine's
`insert_look` selects the new path only when `keepSelected` is on, and with it off left the
selection as it was. Illustrator starts such a stroke by dropping the selection, and the new
stroke is not selected with Keep selected off, so the command now clears the selection after
inserting a new path.
What stays as before: with Keep selected on a stroke selects only the path it draws (the
earlier selection is replaced); a stroke that continues or redraws a selected path with Keep
selected off deselects that path and keeps the rest of the selection. The Blob Brush keeps its
own Keep selected and Merge only with selection options.
`path.freehand`'s documentation, the engine test
`pencil_with_keep_selected_off_leaves_nothing_selected` and the Tool Options test
`the_new_path_is_selected_only_with_keep_selected_on` cover the three cases. Docs: roadmap,
target-app-parity and ui-parity carry the change.
Blob Brush Tool Options gain Angle (-180 to 180 degrees, 0 by default)
and Roundness (0 to 100 percent, 100 by default), with a preview of the
tip and three dabs; a drag in the preview square sets the Angle. The
elliptical tip keeps its angle on the page along a stroke, a 0 percent
tip is drawn 0.1 percent as wide as it is long, and Size set to
Pressure still varies its size. path.blob takes angle and roundness,
and both values are kept with the tool's options.
While a non-round tip drags, the Blob Brush shows the outline of the
area it covers with its length label, and an Alt drag that smooths
shows the Smooth tool's thin line.
Eraser Tool Options' Size takes Fixed or Pressure and a Variation as the
Blob Brush's does: the tool records the pen, and path.eraseRegion outlines
the squashed drag at the pen's widths, stretched back to the tip's angle
and roundness. The pressure parsing and outline move to draw2's common
helpers, shared by both commands.
Blob Brush Tool Options' Size takes Fixed or Pressure and a Variation, as
the brush options' Size does: with Pressure the brush is Size − Variation
wide where the pen presses lightest and Size + Variation where it presses
hardest. The tool records the pen pressure of each point and shows each
step of the drag as wide as the pen pressed there; path.blob takes
[x, y, pressure] points with sizeMode and sizeVariation and outlines the
stroke with that width profile. A stroke without pressure keeps the Size,
and Fixed with no variation stays the default.

A Blob Brush stroke used to merge with every closed path of its fill
color and no stroke that it touched, anywhere in the document, across
layers and groups and past objects of other kinds. It now merges with
the topmost such path it touches, and with the other touched matching
paths in the same group or layer that are next to that path in
stacking order, with no other kind of object between them. Merge only
with selection still limits the candidates to selected paths. The
merged path keeps the topmost path's id and place.
Deleting a point of a finished path with the Curvature tool sent
path.removeAnchor, which refits the two segments that met at the point so
one curve follows them. The path kept the bend of the deleted point
instead of curving through the points that remain.
The tool now sends path.removeAnchor with curvature: true, which uses the
new curvature_remove. Each smooth neighbor takes new handles from its new
neighbors, and an end beside one of them takes its end handle again. A
corner neighbor keeps its handle directions, and its handle on the new
segment scales with the segment's chord. With two points left, the points
that curve lose their handles. Object > Path > Remove Anchor Points and
the Delete Anchor Point tool still refit the curve.
