Per the upstream review of the XDATA-based storage: the host no longer writes
its own state into the saved file. The marker record under the host-owned OCS
APPID, the on-first-use APPID registration and the verbatim-EED rewrite
handling are removed; the single source of truth is a scene-scoped in-memory
set of entity handles (Scene::reference_only) that dies with the drawing tab,
so a reopened file starts undesignated and the owning plugin re-marks on the
document-opened notification.
All behaviour sites are unchanged, driven by the set: the wire stamp moves
from an XDATA read to a set lookup threaded through the tessellation
pipelines (tessellate_entity and the dimension text path take the handle set
as a plain parameter), and the pick filters, selection retains and
update/erase refusals read Scene::is_reference_only.
Undo keeps the entity-write contract: set mutations are recorded as explicit
first-touch before/after values on each history delta (the parametric-
constraints channel pattern). A designation inside a plugin push_undo scope
joins it, a scope-less change is one step of its own, an idempotent re-mark
records nothing, erasing a designated entity drops the set entry with the
entity, and undo/redo restores entity and designation together.
The round-trip test is inverted: reference_only_designation_is_not_written_
to_dwg_or_dxf now asserts the marker appears in neither format's bytes, that
no OCS APPID or marker record survives a reload, and that the designation
stays live in memory.
Host side of HostApi::set_reference_only: plugin-owned display geometry that
renders and snaps normally but must not be edited or picked by the person at
the screen, while the owning plugin keeps full write access through the host.
- Storage: a human-readable marker value in an XDATA record under the
host-owned OCS APPID (registered on first use; foreign values survive
verbatim; stale verbatim DWG EED is dropped on rewrite), so the flag
round-trips DWG and DXF with the entity and cannot collide with plugin
APPID namespaces.
- Grips: refresh_selected_grips yields none for a reference-only entity and
an active grip edit on a newly designated target is cancelled like a
locked-layer one.
- Picking: a reference-only wire flag extends the snap_only skips in every
hit test, so a click passes through to the editable entity underneath, and
box, window, lasso, fence and select-all gathers skip the designation;
fills, solids and instanced meshes are excluded through the shared
candidate handle set.
- Write policy: built-in user paths treat a reference-only entity like a
locked-layer one (Scene::update_entity / update_entities refuse,
erase_entities skips), while the plugin-owned variants
(update_entity_plugin / erase_entities_plugin, mirroring the
remove_entities editor split) and the whole HostSession surface write
through. The MCP entities read exposes a top-level reference_only boolean
and set_properties refuses with the reference_only failure code.
- Undo: the entity-write contract - a change joins a plugin-opened push_undo
scope, a scope-less change is one undo step of its own, refusals and
idempotent re-marks record nothing.
- Known limit: entities nested inside block instances (the block cache
rebuilds instance wires without the flag).

In a tilted 3D view a grip followed the cursor onto the screen plane
through the orbit target, so a circle or arc jumped to another radius and
a polyline vertex left its plane. A model-space grip now moves in the UCS
XY plane at its own elevation (the screen plane only when seen edge-on).
A solid stays drawn while its grip moves, and its own edges were still
snap candidates: a cone's base radius landed on its own side. The edited
entities are left out of the grip's snap set.

The new pointer op sends moves (canvas pixels, or a world point projected
through the camera the cursor edits with), button presses/releases and
wheel steps in order, and reports the cursor's world point after each, so
grip drags and picks go through the same cursor path as the mouse.
click now projects through that editing camera too (it used the model
camera inside an entered viewport), and the grips read reports each
grip's constraint axis.

A layout opened for the first time - one whose sheet viewport had to be
made, or one created in this session - gets a viewport centred on the
printable area, 0.8 of its width and height, zoomed to the model's
extents, while LAYOUTCREATEVIEWPORT is on. The profile variable takes
ON/OFF or 1/0 and is kept with the settings.

A new drawing is metric with metre insertion units, but its annotation
multiplier stayed at Scene::new()'s unitless 1 while opened files and
CANNOSCALE convert paper millimetres into drawing units (0.001 at 1:1).
Annotative text and dimensions were drawn 1000x too large until the
first scale change, then shrank to their real size and looked gone,
also after switching back to 1:1.
One helper now derives the multiplier from the header; new drawings,
file open and every INSUNITS change (UNITS, the units popup, DWGUNITS,
SETVAR) go through it.

- The Image tab gains an Adjust card: X/Y offset in pixels (-2000..2000)
and X/Y scale (-10..10, tenth steps, a negative scale mirrors, zero keeps
the image's scale) with spinners and Reset, inactive while the image is
stretched; Keep aspect ratio is a switch and makes both scales follow.
- The preview shows the image at its offset and scale, tiled when tiled,
and a stretched image kept to its aspect ratio covers the view.

The web control channel gains a save operation that serializes the

Hatches are drawn before the wires and write depth, so a transparent
hatch above lines in draw order still hid them through the depth test.
Transparent hatches now go to their own renderer drawn after the wires:
the lines behind show through the blend and the lines in front still
win the depth test.

A polyline band was stroked like a pen line, with round caps and round
joins, and each segment as its own path, so corners came out rounded
and overlapping. Bands now use butt caps and mitre joins in one path,
and a tapered band fills each segment's quad so a zero-width segment
stays a thin line.

- The background image texture is not an sRGB view: the image is drawn with
its own colours, as the solid and gradient colours are.
- An entered paper-space viewport shows its named visual style (Realistic,
...) in the render-mode picker, and a mode picked there is recorded as the
viewport's visual style.
- The view_background automation action takes offset=x,y and scale=x,y.

add_entity_clone reset handle, owner and mode but kept the source extension dictionary handle, so a copy claimed a dictionary its document does not own. The clone now gets no extension dictionary, like baked and transformed-block children. Failing-first test included.
Filleting a polyline segment with a line or arc moved the segment's
vertex and left the polyline closed and the other object separate, so a
closed shape bent into an unexpected outline. The polyline is now
opened if closed, cut at the fillet point keeping the picked side, and
the fillet arc and the trimmed line or arc are joined onto it as one
polyline, as the reference does.

The codec keeps dynamic-block, associative and material records intact on
DWG save (strict readers rejected re-saved drawings at BLOCKSCALEACTION,
associative action bodies and MATERIAL records). A checker material
texture no longer rewrites the native map source, so a map with a
procedural texture counts as content whatever its source says.
Valuable parts of #1671 (with opencadcodec#100): measured on 235 sample
drawings re-saved after an edit, a strict reader now rejects 4 instead
of 7; the remaining 4 are R14/R2000 tables, which the PR codec also
fails.

- Gradients: the middle colour sits (horizon - 0.5) viewport widths from the
centre and blends over height viewport heights each side; two colours
blend over a viewport height each side.
- Image backgrounds: offset in device pixels (right, down), negative scale
mirrors, fitted with aspect ratio covers the viewport; the dialog keeps an
image's offset and scale.
- Layouts: a model-space view restored on a sheet asks for the viewport,
enters it and gives it the view's camera, background and visual style;
inside a viewport the view goes there; a paper-space view's background is
kept on the sheet viewport but not drawn; floating viewports draw their
background.
- Background objects no view or viewport uses any more are erased; a view
without a background restored where the viewport already is leaves the
viewport's background.
- The viewport's named visual style (Realistic, ...) shows by name and the
render-mode picker records its style on the viewport record.
