AutoCAD 2024's SCALE is a uniform 3D scale about the base point: every Z
and elevation scales about the base point's Z (the current ELEVATION for a
point given without one) and every thickness by the factor. cadcraft
scaled X and Y only. The JSON form also takes a Z with the base point.
OFFSET's copy now keeps the source's height: a line's end Zs, a circle's
or arc's centre Z, a polyline's elevation. A circle's or arc's copy has no
thickness and a polyline's keeps it, as AutoCAD makes them.
Grip scaling, ALIGN's scale option and MOCORO stay 2D: their base point is
often a grip or snapped point whose Z cadcraft doesn't keep.

* LISP: entity names answer prompts that pick one object
`command` fed an entity name, alone or as `entsel` returns it (name and
point), to the running command as a pick. Prompts that pick a single
object with a point (MEASURE, DIVIDE, LENGTHEN, PEDIT, BREAK, TRIM and
EXTEND in Standard mode, FILLET, OFFSET, REVCLOUD Object, dimensions…)
only take points, so routines got "Invalid input" or nothing at all.
At such a prompt the name is now entered as its point, and a pick at
exactly that point finds the named object (Session::pick_object), so
the point says where on it, as in AutoCAD. A bare name stands at the
object's DXF group 10 point, the point AutoCAD picks it at: a line's
start, a circle's or an arc's centre, a polyline's first vertex. At an
arc's centre MEASURE runs from the arc's end, as AutoCAD does.

* Keep a named object for its own input and its own space
A name given at a prompt picking one object now holds only while that
input is taken: a later pick at the same point finds what lies there.
A name for an object in another space picks nothing, instead of the
object under its point in the current space.
