8cd0d46d58 Zoom and pan regenerate in the background instead of freezing the window (#903)
* Zoom and pan regenerate in the background instead of freezing the window

A rebuild that only the view asks for (a new 2x zoom band, a pan out of the
built area) now runs on a worker thread while the canvas keeps drawing the
previous display list, scaled by the view uniform. The worker builds the list,
converts it to vertex data and creates the GPU buffers, so the frame that swaps
it in only swaps buffers. One build runs at a time; a result from an older
drawing revision is dropped. Edits, the first build and the web build (no
threads) still rebuild synchronously.

ZOOM no longer calls touch(): it changes the view, not the drawing, and the
bumped revision made every typed zoom a full blocking rebuild (wheel zoom
never did). REGEN, REGENALL and layout switches still touch.

ui.screenshot waits (up to 6 s) for a background rebuild so agents capture
the new view; ui.inspect perf reports "building".

On a hatched 12k-entity DWG (~340k primitives) the longest UI stall per zoom
went from 2-4.5 s to 26-64 ms.

Also: cargo fmt of a comment in engine/src/prompt.rs that was failing the fmt
gate on main.

* Cancel a background rebuild when the view moves on

A view that needs a different display list now cancels the build in flight
and starts one for itself, instead of waiting for the outdated build to land
and only then starting the next. A long scroll through many zoom bands builds
only for where it stops: the list lands about one build after the last step
(2.0-2.3 s on a hatched 12k-entity DWG) instead of up to two, and an outdated
build no longer keeps a core busy.

cadcraft_render::Options gains `cancel` (an Arc<AtomicBool>); a set flag stops
the build at the next entity (block contents included) and the hatch sweep at
its next pattern line, returning a partial list the caller discards. The
canvas's Job sets its flag when dropped, so replacing or dropping a job
cancels it; a cancelled worker sends nothing.

033ee15e01 Fix double-clicking layout viewports creating persistent selection rectangle (#830)
Double-clicking a viewport to enter MSPACE or sheet to enter PSPACE triggers a primary click on the first click that starts an idle selection window (pending_window). When the second click triggers dbl_primary, the handler executed an early return, leaving pending_window open and rendering an unwanted crossing/window rectangle across the screen. Reset pending_window and drag_window on double clicks and suppress primary click dispatch.

26179f7428 Draw object transparency on screen, in exports and in plots (#764)
* Draw object transparency on screen, in exports and in plots

Transparency was read and saved (entity group 440, layer xdata, ByLayer and
ByBlock) but never drawn. Display lists now carry each object's effective
transparency (its own, its layer's, or the block reference's), and:

- the canvas (GPU and CPU paths), ui.render and PNG/SVG exports blend it;
  TRANSPARENCYDISPLAY turns it off on screen and is now on by default, as in
  AutoCAD (initial value 1);
- plots draw it only when "Plot transparency" is on: a page setup option
  (PAGESETUP `plotTransparency`, a checkbox in the Page Setup Manager and the
  Plot dialog), overridable per plot, with PLOTTRANSPARENCYOVERRIDE (0 never,
  1 the setting, 2 always). PDF gets /ExtGState alpha, PNG plots blend, SVG
  uses opacity. Plots without it are byte-identical to before.

The public DXF Reference has no plot layout flag for plot transparency, so
the option is kept in the session and in JSON, not in DXF/DWG.

* Transparency fixes: attributes, PDF overlaps, drag previews

- Attributes draw with their own transparency (their definition's, layer 0
  meaning the reference's layer, ByBlock the reference's) instead of the
  block reference's.
- PDF plots stroke overlapping transparent objects one by one, so they build
  up where they cross as in PNG plots; opaque output is unchanged.
- Drag and rubber-band previews follow TRANSPARENCYDISPLAY.
- Effective transparency is worked out only when it is drawn, reusing the
  layer the property lookup already found.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Transparency: one PDF stroke per transparent primitive; opaque rebuilt previews

- PDF plots never batch two transparent primitives into one path. Block and
  viewport contents share their reference's handle, so the per-object flush
  missed them; each primitive now blends on its own, as in PNG plots and on
  screen. Opaque output is unchanged.
- Previews the session rebuilds with the current properties (rubber bands,
  copies of objects) are drawn opaque again: they carry CLAYER's
  transparency, not the objects'. The GPU drag of the objects themselves
  keeps following TRANSPARENCYDISPLAY.
- Tests for attributes on a transparent reference layer, attributes without a
  definition, and the drag cache across the TRANSPARENCYDISPLAY toggle.

* Selection like AutoCAD: colour highlight and the Options Selection tab

Selecting or hovering an object outlined each filled primitive (TrueType
glyphs, dimension and leader arrowheads, solid hatches, wide polylines)
by the rectangle around its triangles, and dashed everything else. A
selected dimension's text became a row of dashed boxes, one per glyph,
and its closed arrowheads small rectangles.

Selected objects are now redrawn in the selection colour: lines solid,
fills filled half see-through (so the lines and text on a highlighted
hatch stay visible), and the whole object reads as selected, text and
arrowheads included. A wipeout is always outlined, since filling it would
hide the drawing under it.

The Options dialog's Selection tab is laid out as AutoCAD's, with the
settings CADCraft can act on, each one AutoCAD's variable, kept in the
user profile:

- Selection modes: noun/verb selection (PICKFIRST), Shift to add
  (PICKADD), Object grouping (PICKSTYLE bit 1, now saved in the profile).
- Selection effect color (selectionColor, an interface preference; null
  is the theme's).
- Grips: Show grips (GRIPS) and the object selection limit for display of
  grips (GRIPOBJLIMIT, 100; 0 no limit): grips are neither drawn nor
  picked beyond it.
- Selection preview (SELECTIONPREVIEW): the object under the cursor is
  highlighted when a command is active (2) and when none is (1).
- Visual Effect Settings: the selection area effect (SELECTIONAREA,
  WINDOWAREACOLOR 150, CROSSINGAREACOLOR 100, SELECTIONAREAOPACITY 25)
  and the Selection Preview Filter (PREVIEWFILTER 3: 1 objects on locked
  layers, 2 xrefs, 4 tables, 8 multiline text, 16 hatches, 32 groups).

As in AutoCAD these are typed, not on the dialog: HIGHLIGHT (0 shows only
the grips of selected objects; not saved, so every session starts
highlighted), SELECTIONEFFECT (1 the selection colour, 0 dashed lines with
fills outlined along their real boundary) and PREVIEWEFFECT (the preview
dashed 0, thicker 1 or both 2).

Left for later, as CADCraft lacks what they control: lasso, grip tips and
menus, group grips, grips within blocks, associative hatch selection,
command and property preview, PICKDRAG, PICKAUTO and PROPOBJLIMIT.

DisplayList::fill_outlines returns the boundary of the region a filled
primitive covers as closed polylines (edges only one triangle has; the
slab filler's horizontal cuts, which need not line up between trapezoids,
are split at every x on their line and kept where an odd number cover
them), falling back to the bounding box over 600,000 vertices. The GPU
and CPU highlight paths and the drawing comparison overlay share the same
looks.

The new labels have Ukrainian rows (the required catalog); other
languages fall back to English.

e74b276dfd In-place MTEXT editor with formatting toolbar and indent/tab ruler (#532) (#792)
The MTEXT text entry opens a text box on the canvas at the text's location and
width instead of a dialog: font, height, bold, italic, underline, overline,
colour, paragraph alignment, lists, tab and special characters, plus a ruler for
the paragraph's indents and tab stops. Text, per-character formats and paragraph
properties live in engine::mtext_edit (parse and write MTEXT codes, opaque codes
kept verbatim), tested headlessly.

d826450e03 Block Editor on the current drawing; a drawing with authoring elements offers it (stacked on #833) (#885)
* Block Editor: BEDIT, BSAVE, BSAVEAS and BCLOSE for static blocks

BEDIT opens a block definition in the drawing's own tab with its base point
at the origin, and the block's objects are edited with the ordinary commands.
BSAVE writes them back into the definition, so every reference in the drawing
updates (one undo step in the drawing); BSAVEAS saves under a new name;
BCLOSE goes back to the drawing, asking whether to save unsaved changes.

- The drawing waits untouched while the editor is open (blockedit.rs): its
  undo history, selection and views come back on BCLOSE. Objects left
  unchanged are saved back exactly, so no coordinate drifts.
- Files save the drawing outside the editor; autosave keeps the editor's
  unsaved changes in the block; the close/quit prompt's Save puts them into
  the block first.
- Right-click a selected block reference: Block Editor. In the editor the
  canvas is tinted, the base point is marked, and a bar offers Save Block,
  Save Block As and Close Block Editor (also in the right-click menu). The
  Block tool set's Block Editor button is now live. BLOCKEDITOR sysvar.
- Layout and paper-space commands are refused while the editor is open; a
  block can't be saved to contain a reference to itself.
- Dynamic blocks: their data is kept; the editor says it can't edit their
  parameters yet.

BEDIT typed or started from a menu or the Tool Sets with no block reference
selected opens the Edit Block Definition dialog: the drawing's blocks sorted
by name, a preview and the description. OK opens the Block Editor on the
block named; a name no block has yet starts a new block, which BSAVE creates
(`bedit {name, create: true}`). A selected block reference still opens at
once, and JSON calls never open the dialog.

A dynamic block reference with values of its own shows an anonymous block

names its dynamic block in AcDbBlockRepBTag xdata; BEDIT now opens that, as
AutoCAD does. Regression test.

* Block Editor on the current drawing; opening a drawing with authoring elements offers it

A dynamic block's own drawing (model space with authoring elements: its
block record's ACAD_ENHANCEDBLOCK) opened from the UI asks, as AutoCAD does,
"<file> contains authoring elements. Open in Block Editor?" Yes / No /
Cancel. Yes opens the Block Editor on <Current Drawing>: the drawing's own
objects, edited where they are; BSAVE keeps them, BCLOSE without saving puts
the drawing back. <Current Drawing> heads the Edit Block Definition list.
BSAVEAS is not available there.

62fb5ae79a Attributes keep Verify, Preset and Lock position (stacked on #854) (#876)
* Multiline attributes: read, draw and save their text

A multiline attribute (DXF attribute type 2, or 4 for a definition) has its
text as embedded MTEXT after its own groups (`101 Embedded Object`); its own
group 1 is empty. CADCraft read only the own groups, so the attribute drew
nothing, and a save wrote it back empty: its text was lost.

- `Attrib::multiline` keeps the multiline text; `text.value` holds its plain
  text, which ATTEDIT and the other value editors change; an edited value
  replaces the contents (`Attrib::multiline_text`).
- DXF read: ATTRIB and ATTDEF split at the marker; the MTEXT parsing is
  shared with MTEXT entities (`mtext_from`).
- Drawn as multiline text; ZOOM Extents counts it.
- DXF write (2007 and later; earlier versions get one line): attribute type,
  alignment point and the embedded MTEXT, only what differs from unrotated
  text, as AutoCAD writes it.
- INSERT and ATTSYNC give references the definition's multiline text placed
  with them; MOVE/ROTATE/SCALE, Properties rotation and scale, annotative
  scaling and FLATTEN carry it.
- Tests: synthetic multiline ATTDEF and ATTRIB (read, drawn, saved, edited,
  pre-2007 save, damaged embedded groups); engine INSERT, MOVE, ATTEDIT and
  ATTSYNC.

* Attributes keep Verify, Preset and Lock position

ATTDEF/ATTRIB flags 4 (verify) and 8 (preset) and Lock position (group 280
after the tag, DXF 2007 and later) were dropped on save. Without Lock
position AutoCAD lets an attribute be dragged out of its reference, and its
dynamic block actions no longer carry it. A reference's attributes take Lock
position from their definitions, as AutoCAD saves them.

48352f2baf Dynamic block grips: show and drag a dynamic reference's grips (stacked on #878) (#883)
* Dynamic blocks: read parameters and actions from AutoCAD files

A dynamic block's evaluation graph (kept as foreign data since #528) is read
into a typed model, `cadcraft_doc::dynblock`, without changing the kept
data: parameters (linear with value sets, point, visibility states,
lookup, base point; polar, XY, rotation, alignment and flip by geometry)
and actions (stretch with its frame and moved vertices, lookup tables;
move, scale, rotate, flip, array, polar stretch by kind), each with its
graph id and the parameters it follows.

- `blocks.dynamic {name}` returns the model as JSON (handles as hex);
  `blocks.list` marks dynamic blocks.
- Counts and values come from the file: capped by the groups present,
  non-finite numbers and missing members skipped.
- Tests: a synthetic DOOR block (visibility, linear list, stretch, lookup),
  its survival through a save, damaged data, and the engine commands.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Dynamic block references: their values and custom properties

A dynamic block reference's extension dictionary says which dynamic block it
shows (AcDbBlockRepresentation ▸ AcDbRepData) and the values it was given
(AppDataCache ▸ ACAD_ENHANCEDBLOCKDATA, one XRECORD per parameter graph id).
`dynblock::reference` reads them; a reference to the dynamic block itself
has the block's values.

* Dynamic block references: change the visibility state

Choosing a visibility state (or a lookup value whose tables set only
visibility states) in Properties ▸ Custom, or `blocks.reference.set
{handle, name, value}`, changes a dynamic block reference as AutoCAD does:

- The reference gets a new anonymous block: its current one with the
  state's objects shown and the parameter's other objects hidden (matched
  to the dynamic block's objects by their AcDbBlockRepETag element tags).
  The old anonymous block goes when nothing else uses it.
- AutoCAD's link data is written: the new block's record carries
  AcDbBlockRepBTag (the dynamic block's record), copied objects keep their
  element tags, and the reference's AcDbBlockRepresentation data records the
  value (an existing value record is updated; a new one copies another
  reference's record for the same parameter when there is one).
- An attribute whose definition the state hides is written hidden (60).
- Changes CADCraft can't make yet (distances, positions, lookups that set
  them) are refused with a message and change nothing; Properties shows
  only what can change as a dropdown (`CustomProperty::editable`).
- Tests: the synthetic DOOR references (own values and an anonymous block),
  survival through a save, refusals, and the engine command with undo.

* Dynamic block references: distances, positions, stretch and move actions, lookup chaining

Linear distances (snapped to their value sets) and point positions can be
changed; the stretch and move actions that follow them run (listed vertices
or whole objects, multiplier and angle offset), parameters in an action's
selection are carried along, associative hatches refill from their
stretched outlines and the reference's attributes move with their
definitions. Lookup tables run both ways (a changed input gives its table's
lookup value, which sets the other tables' inputs). Connections are read in
either group order. Checked against AutoCAD's own references (*U10, *U12).

* Dynamic block references: record changes in the history as AutoCAD does; full value data for new references

A changed reference's ACAD_ENHANCEDBLOCKHISTORY says what was done to it: a
visibility state or lookup value by property name, a distance or position as
the drag of its grips (GRIPLOC, how far each grip is from where the dynamic
block has it). A reference that had no data gets a record for everything
other references of the same dynamic block have, with its own values.
Templates come only from references of the same dynamic block; anonymous
copies have no units; boundary reactors follow the copies.

* Dynamic block history: record only the grips a change moves

AutoCAD's history holds the user's own drags; a grip that only moved with
another parameter (a stretch carrying it) gets no entry.

* Dynamic block history: a distance by name, as typed in Properties

AutoCAD records a distance typed in Properties as the parameter's name and
value in block units (1071 id, 300 Distance2, 40 40.0), replacing drags of
its grips; positions stay grip drags.

* DWG: dynamic block lookup parameters keep their name and lookup action

AutoCAD writes a lookup parameter's subclass marker as
AcDbBlockLookUpParameter; the DWG bridge reads AcDbBlockLookupParameter and
matches it exactly, so the parameter's name (303) and lookup action (94)
were lost in DWG files and AutoCAD's lookups stopped working (a visibility
change no longer resized the block). The bridge DXF now uses its spelling.

* Dynamic blocks: carried parameter points are in a stretch frame where the block has them

AutoCAD evaluates actions from the dynamic block itself, so a parameter point
another action has moved out of a stretch frame still follows it. Testing the
current position instead changed a stretched label's width when its
visibility changed (Distance2 183.75 became 184.45; AutoCAD keeps 183.75).

* Dynamic block grips: show and drag a dynamic reference's grips as AutoCAD does

A selected dynamic block reference shows its grips: an arrow at each end of a
distance, a square at a position, a down-pointing triangle for a visibility
or lookup list, only those its visibility state lists. Dragging an arrow
changes the distance along the parameter (snapped to its values; a typed
number sets it), a square moves the position, a list grip offers its
choices; actions and lookups follow, with a live preview.

doc: dynblock::grips, drag_grip; grip objects by graph id.
engine: blocks.reference.grips, blocks.reference.grip, Session::start_dyn_grip.
ui: canvas dynamic grips (GRIPDYNCOLOR-like token), list popup.

* Dynamic blocks: read parameters and actions from AutoCAD files

A dynamic block's evaluation graph (kept as foreign data since #528) is read

run_hatchedit read `scale` and `angle` leniently (a non-positive scale or a

undo step and cleared the redo history, applied its valid companion property
or recreated the boundary. HATCH already refuses a non-positive scale. The

a number; absent and null still mean "leave it".

8abc0909f3 MCP: render one area of the drawing, and read its texts (find_text) (#757)
A render of a large drawing (a set of sheets in model space) fits every
sheet in one image, too small to read. `render` takes `window`
[[x0,y0],[x1,y1]]: just that area, 1600 px wide with the window's shape
unless sized (the app's and the headless `ui.render` both; the display list
is built for that view only). `View::of_window` sizes it.

`find_text` (engine command `texts`, read-only) returns the readable text of
TEXT, MTEXT (formatting removed), block attributes and multileaders with
insertion point, height, rotation, style, layer and handle, filtered by
content, layer and a window. FIND selects and can replace; this only
reports, so an agent can find room names, sheet numbers and titles without
reading all the geometry.

On a 39,600-object permit set: 5,861 texts in 0.02 s; one 90 x 59.4 sheet
rendered at 2400 x 1584 in 0.5 s.

8166e4a809 AutoLISP: load and run .lsp routines (fixes #758) (#855)
* AutoLISP: load and run .lsp routines (#758)

CADCraft runs AutoLISP routines. `.lsp` files load with APPLOAD, (load)
or by dropping them on the window, and at startup from the support folder
(acad.lsp once per session or per drawing with ACADLSPASDOC, acaddoc.lsp
per drawing, then S::STARTUP; never from a drawing's own folder).
(defun c:NAME …) defines commands, (autoload) defers loading to first
use, and (expression) and !variable work at the command line and at
prompts. docs/autolisp.md lists what is supported.

The interpreter (crates/engine/src/lisp) reads source with its own
stack and evaluates on an explicit-stack machine, so a routine can stop
for input (getpoint, pause in command) and carry on later on one thread,
deep recursion is an error rather than a crash, and long loops run a
slice per frame (Esc stops them). It follows AutoLISP: 32-bit wrapping
integers, dynamic scope, *error*, vl-catch-all-apply, AutoLISP's error
wording. About 200 built-ins cover the language, command (with pause and
commands left open), entity lists (entget/entmake/entmod/entdel/entlast/
entnext/handent, through the DXF reader and writer's groups, exposed by
cadcraft-io and handed to the engine through a hook), ssget with modes
and filters, tables, system variables, get… input with initget, and
units. A routine is one undo step; each drawing has its own symbols.

Also: keywords typed as _KEYWORD match at prompts; TEXT run by a
routine's command takes one line; DIMENSION records carry their
measurement (42); Prompt::raw shows a get… prompt as written; the
interface asks Session::prompting() (a command's or a routine's prompt)
where it asked whether a command runs, so clicks, right-click and Delete
work at a routine's prompts; getcorner and based get… prompts drag a
rubber band.

Tests: the language, errors, startup files, interactive input, hostile
input (lisp/tests.rs); the #648 corpus, 18/18, when CADCRAFT_LISP_CORPUS
points at it (tests/lisp_corpus.rs); drop, frames and canvas clicks in
the app (ui-egui/tests/lisp_files.rs).

* AutoLISP: bound memory, drop nested values iteratively, guard the per-frame tick

- Cons cells drop with a work list over both car and cdr (and function
  bodies), so a list nested a million deep in its car no longer overflows
  the stack when it goes away.
- Memory caps so a runaway routine fails with a LISP error instead of an
  uncatchable out-of-memory abort: at most 5,000,000 live cons cells
  (counted in Value::cons / Drop, checked every step; cells the drawing's
  variables already held at the run's start don't count against it), no
  string a built-in makes longer than 8 MiB (strcat checks before joining,
  printed text is cut), and a 2 GiB per-run budget for new strings,
  printed text and files read.
- Session::lisp_tick runs under catch_unwind, and so does every slice of
  the LISP machine: a panic ends the routine with "internal error", puts
  the drawing back and leaves the session usable.
- Regression tests for each (deep car nesting, nested functions, the cell
  cap, string length and budget, a panicking built-in in a blocking run
  and in a ticked one).

1c4d0a543f Open damaged DWGs partially and say what was left out (#800) (#859)
Bump acadrust to 0.6.4 and read DWG in its failsafe mode: an object
record the reader can't decode is skipped instead of failing the whole
file. The drawing's new read_notes (never saved) say how many records
were left out and of which types; OPEN echoes them, returns them as
`warnings`, and the app shows the first in the status bar. A file whose
objects stream can't be read at all is still an error.

acadrust 0.6.4 writes a merged table cell's anchor with 173=0 and the
span, so the DXF reader now takes a merge from the span alone. Unknown
records the DWG writer can't write back are dropped before writing.

3b16f2d516 Engine: run the post-command passes from one place (#856)
`execute` and the interactive `finish` each called the group, constraint and
associativity passes in sequence, with slightly different arguments. They now
both call `Session::after_command(before, uid, ok)`, which lists the passes
once, so a pass cannot be added on one path and missed on the other. The
arguments each path passed are unchanged: `execute` passes the document uid and
`undoable && ok`; `finish` passes no uid and `true`.

tests/post_command_passes.rs pins that MOVE and ERASE, run through `execute`
and typed, prune groups, purge/re-solve constraints and update an associative
hatch identically, in one undo step that undo fully reverses.

2f5bbbd68d doc: Space::tab_name / layout / is_paper replace repeated hand-written matches (#888)
* doc: Space::is_paper/layout/tab_name helpers replace hand-written matches

Twenty-seven call sites in 15 files across engine, io and ui-egui matched Space by hand to get
"is this a layout", "which layout" or "Model or the layout's name". Route them
through three small helpers on Space instead. No behaviour change.

This also makes adding a space kind a few-file change.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* doc: keep Space::Model comparisons that no helper shortens; test the helpers

Only the sites that repeated the same match (tab name, layout name,
paper lineweights) go through the helpers; plain Model comparisons and
plot_window's match on (space, plotArea) stay as they were.

* MTEXT: paragraph indents and tab stops are in drawing units

AutoCAD writes \pi, \pl, \pr and tab stops in drawing units, not multiples of the text
height. A file with \pi27.485 on 6-high text in a 120-wide box laid out with a 165-unit first
line indent: the first line vanished and wrapped words landed elsewhere. The JSON mtext
parameters indent, firstIndent, rightIndent and tabs follow (a list's default indent is now
3 text heights, in drawing units).

8e0b867f6c BREAK, BREAKATPOINT and JOIN: leave objects on locked layers alone (fixes #727) (#730)
BREAK and BREAKATPOINT (break_entity) and line/arc/polyline JOIN
(modify::join) removed their source objects and added replacements
without checking the source layer's lock, so a locked line could be cut
or merged into a polyline. ERASE, MOVE, TRIM, FILLET, EXPLODE and the
ellipse/spline JOIN already guard against this.

Both now refuse with the same errors the sibling commands use:
"The object is on a locked layer." (BREAK, BREAKATPOINT, like FILLET)
and "An object is on a locked layer." (JOIN, like the ellipse/spline
join). JOIN refuses the whole request when any selected object is
locked, so a mixed-layer pair keeps its locked original in either
order. The guards sit in the shared functions, so JSON calls with
explicit handles or the selection, the interactive prompts and the
command line all reach them. The interactive commands report the
refusal on the command line.

Tests (crates/engine/tests/break_join_locked_layers.rs, red before the
fix): BREAK and BREAKATPOINT on a locked line by handle and by
selection; BREAK on a locked arc and circle; JOIN of locked lines and
of a locked/unlocked pair in both orders; interactive BREAK and JOIN.
Each checks the drawing is unchanged while locked, and that the same
edit works unlocked (BREAK also undoes and redoes).

f807e65e30 STRETCH: polygon and fence selection (#892)
At "Select objects", CP and WP take a polygon (Enter closes it) whose
inside marks the vertices that move, as a crossing window does; F takes a
fence, and what it crosses moves whole, like objects picked one at a
time. BOX works too, Undo takes back the last point, and the polygon or
fence is drawn while its points are placed.

The JSON form takes `polygon` or `fence` in place of `window`; both are
capped at the selection modes' point limit and refuse non-finite points.

69f2b9724a Save xref layer overrides with the host, in DXF and DWG (fixes #886) (#889)
A colour or freeze set in the host on an xref's layers (xref|layer) was lost on save:
the saved view dropped every xref-dependent symbol, layers included, and the DWG save goes
through the same DXF tags. The reader already keeps such layers when the xref loads.

The xref's layers are now written as xref-dependent LAYER records (DXF Reference, LAYER
group 70: 16 externally dependent, 32 resolved), as AutoCAD does with VISRETAIN = 1, with
the xref linetypes they use (same flags): without them a DWG falls back to Continuous.

5fd23f75fc Command line: a bare system variable name runs SETVAR on it (part of U10) (#799)
* Command line: a bare system variable name runs SETVAR on it (part of U10)

Typing ORTHOMODE, PICKADD and the like at the command line returned
"unknown command". Session::start now falls back to SETVAR with the name
already entered when the text is not a command but is a known variable;
dash, dot and underscore prefixes never mean a variable, and real
commands still win. Read-only variables print their value, and the
transparent form ('OSMODE) resumes the interrupted command.

Checked: fmt, clippy, test, assets, layers and wasm pass; also driven
through the control channel in the running app.

Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

* Tests: every variable name, command collisions and hostile input for bare SETVAR

Covers each variable SETVAR lists: a name that is not a command starts SETVAR
(or prints a read-only value), a name that is also a command keeps the command,
and odd input (lone apostrophes, NUL, wide characters, a 1 MiB name) never
panics and leaves the session usable. Disabling the fix makes all three new
and old tests fail.

mattlafyandClaude Opus 5.5 d134079f11 Xdata travels with its object: COPY, MIRROR, ARRAY and paste keep it (#890)
Other applications' xdata on an entity was kept beside the drawing,
keyed by handle, so a copy (new handle) lost it: a copied hyperlink
(PE_URL) had no link, third-party tags stayed on the original only.
In AutoCAD xdata is part of the object.

Move entity xdata onto the entity as Common::xdata (the same raw
groups); every copy path already clones Common. The DXF reader puts it
there (handle references still noted for remapping), the writer takes
it from the entity, PDF hyperlinks come from the entities. EXPLODE's
pieces of an object don't inherit its xdata. Table record and block
xdata stay in Foreign.

5ce44acfb2 Pick dimensions and multileaders anywhere on their text (#807)
Plain TEXT and MTEXT are picked anywhere inside their box, but a
dimension or multileader was only found near its lines: its hit geometry
is built without text. Hovering or clicking the words of a dimension found
nothing (on a survey plan, 2 of 34 letters of a dimension's text).

A point inside the box around the words, turned with the text, now picks
the object. A dimension with a block, as AutoCAD saves them, is drawn
from that block, so its text box comes from the TEXT and MTEXT in the
block, not from the text the dimension's own geometry would place (on the
same plan that was a different place, eight times smaller). A
multileader's text box comes from its MTEXT layout.

aldozarandClaude Opus 5.5 e9d8462828 Keep the ACIS geometry of 3D solids, regions and bodies on save (ACDSDATA) (#781)
From AutoCAD 2013 on, a 3DSOLID, REGION or BODY doesn't carry its ACIS
geometry: the binary SAB lives in the file's data store section (ACDSDATA),
one ACDSRECORD per entity bound by a 320 handle. CADCraft kept those
entities (as unknown entities, with their handles) but dropped the section,
so a drawing saved as DWG or DXF had empty solids, and saving reported them
as not saved.

- doc: Foreign::data_store keeps the section's groups as read;
  data_store_entities() lists the entities it has records for.
- io: the reader keeps the section; the writer puts it back for files of
  2013 and later (and in the DXF the DWG bridge converts, which acadrust
  reads into the DWG), without the records of entities no longer written.
  Nothing is written for older files or when no record's entity remains.
- engine: not_saved_as(d, version): from 2013 a solid, region or body with a
  data store record isn't reported; saves and document.bytes pass the version
  being written.

On a 39,600-object permit set with 625 3D solids and 2 regions, DWG ->
CADCraft -> DWG now keeps all 627 bodies with byte-identical SAB (before:
none), and the save no longer reports them.

A command started in one drawing kept running after a programmatic NEW or OPEN made another
drawing current. Finishing it there recorded an undo step holding the first drawing, so undo in
the new drawing brought the other drawing back. Session::new_drawing and open_drawing now end a
running command before the new drawing becomes current, as CLOSE and document.switch already do
and as starting NEW from the command line did: its undo step lands in the drawing it started in.
With no command running, nothing changes (the previous drawing keeps its selection).
