Commands whose `id` or `ids` the shared check in Session::execute does not
read still parsed them with id_param/ids_param, which drop anything that is
not a non-negative integer, and then acted on the selection or the current
layer. `object.blend.make {"ids": 3}` blended the selection,
`object.envelope.makeWithWarp {"ids": [2, "x"]}` warped the selection,
`graph.setData {"id": "2"}` changed the selected graph and
`layer.newSublayer {"parent": "2"}` added a sublayer to the current layer.
- cmd::named_ids and cmd::named_id read `ids`/`id` as targets does: a value
that is not an object id, or an unresolved step reference, is an error.
- The symbol and brush, Live Paint, Shape Builder and Image Trace, blend,
envelope and mesh, perspective, Liquify, Puppet Warp and graph helpers use
them in place of the lenient readers.
- layer.clippingMask.toggle checks `id`, and layer.newSublayer checks
`parent`, with checked_id before falling back to the highlighted row or the
current layer.
Homography::then_after returned products whose entries could overflow to
infinity or become NaN. A move, transform or grid reproject of type or a
symbol instance whose stored projection has large finite entries stored such
a product, and the type was then drawn flat, since a projection that is not
finite reads as none.
- Homography::checked_then_after returns None when an entry of the product
is not finite.
- project_node composes each type and symbol instance projection with it and
returns false, leaving the object as it is, when one would not be finite;
moves and transforms in perspective and Define Perspective Grid with
reproject then return the horizon error and leave the document unchanged.
- transform_map, attach_homography and size_homography return None for such
a product.
- Edit Text returns the horizon error, and does not enter isolation mode,
when the type cannot be shown flat where it is drawn.
perspective.move takes constrain: true instead of a plane-space
direction. For each object, the command snaps the move to the nearest
axis or 45-degree diagonal of that object's own plane, so a selection on
several planes keeps every object on a line of its plane. The tool sends
the raw pointer with the flag.
On a diagonal, Snap to Grid now moves along the diagonal by the nearer
per-axis correction, so that edge lands on its gridline.
perspective.move takes an optional constrain: [dx, dy], a plane-space
direction. For an in-plane move, Snap to Grid's correction is projected
onto that direction, so a move the Shift key constrains to a plane axis
or a 45-degree diagonal stays on that line when an object edge lies near
a gridline. The Perspective Selection tool sends the direction for
Shift moves and copies. Moves without the param behave as before.
