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.

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.

Drawing (#674): in stroke-font (SHX) text, East Asian wide characters
from a fallback font fill a square cell from the baseline to the text
height, as a big font's do, instead of being scaled by the fallback
font's Latin cap height (about 1.3-1.5x too large and too widely spaced,
so CJK labels overran their space). A line no longer ends with the
stroke font's letter gap after a fallback glyph.
Interface (#513): a CJK font is installed after the Latin one in every
interface language, not only Chinese, so Japanese or Chinese file,
layout and layer names stop showing as boxes. A Japanese font comes
first unless the interface is Chinese; a craft-fonts face embedded in
the build comes last, for systems (and the web build) without one.

Another program's file can name a $HANDSEED below handles it uses (a DWG
read through the bridge did: its seed was under the handles of its
dimension blocks). The faces a polyface mesh becomes were numbered from the
seed while reading, so they could take handles of records further on in
other lists (another block); within one list duplicates were already
renumbered. A DWG keeps one object per handle, so saving one lost the
duplicates: 15 faces of a block's mesh in a permit set.
Before entities are read, every handle a file uses is now reserved. A file
CADCraft wrote names its own next handle (#495), above which its rebuilt
records are numbered, so it is left to that and resaves stay identical.

Saving regenerated every dimension's anonymous block, even dimensions read
from another program's file and never touched: the definition points went
and other programs then showed CADCraft's drawing of each dimension (a
dimension line split around its text came back whole, for instance).
A dimension still linked to the block it was read with hasn't changed
since: every edit drops the link, and the screen draws that block while it
is there. Its block is now written as read, under its name and handles;
edited and new dimensions are generated as before.
On a 1,013-dimension permit set saved DWG -> CADCraft -> DWG, every
dimension's block now matches the original (before: none).

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.

MCP clients start their servers when they start, usually before CADCraft is
open, and `--connect` refuses to start then. `--lazy` starts the bridge
anyway and reaches the app at the first tool call; until the app answers,
each call fails with how to open it. `--launch` (implies --lazy) opens
CADCraft on macOS with that control port at a call that finds nothing, and
waits up to 30 s. Neither falls back to a headless session (#103).
