Inside a block, text-bearing and wide wires got their child rank as a
depth override, but fill-only wires stayed at the bare insert level. A
dimension's baked MTEXT with a DIMTFILL background therefore drew its
box in front of its own text whenever the text's rank fell below zero:
cyan boxes with no numbers. Fill-only wires now take the rank as well,
so a background ties with its text and the text pass wins.

A DWF sheet or DGN model is drawn as world-space wires (one line wire per
colour and width, one fill wire per colour) instead of a raster rescaled
to the view, so it stays sharp while zooming instead of showing pixels
until the raster is made again. Colours go through the colour table
mapping, contrast, fade and monochrome; clip boundaries clip the wires.
The wires are drawn and plotted but neither picked nor snapped; the
underlay's own snap geometry still serves object snaps.

One-pixel hairlines keep horizontal and vertical pieces solid, but
slanted pieces and curves are anti-aliased: their pixel steps broke up
into dashes once the raster was scaled to the screen.

- V8 models are placed relative to their global origin (model header).
- A V8 model's extent is the union of its elements' stored ranges; a V7
model's text box is one text height tall.
- Files without a colour table use the standard DGN default table; colour
255 is read from the table's background entry.
- Colours from a file's colour table follow the background: near-white
colours swap with it, and over non-black backgrounds some shades drop a
step.
- DGN contrast pulls towards a pivot taken from the model's own colours,
after the fade, which is blended into the background first.
- Shared cells are read through their full 3D placement, so tilted
instances and 3D definitions are drawn in plan.
- Deleted V8 elements are skipped; lines along the model's extent stay in
the raster.

Every near-white colour turned black on a light background (and near-black
white on a dark one), including true colours. A 255,255,255 solid used as a
white mask became a black block. Now only colour 7 swaps: true colours and
ACI 255 resolve a hair off pure white/black and keep their value on screen
and in plots.

- Add transform_ellipse_geometry helper in scene::view::transform to compute exact principal semi-axes, normal, ratio, and shifted arc parameters under any affine transform (negative scales, reflections, negative rotations, non-uniform scaling, and translations).
- Use transform_ellipse_geometry in block_cache::transform_tangent for TangentGeom::PlanarEllipse so GPU analytical instances and curve endpoints match true WCS positions.
- Update entities::ellipse::apply_transform to use transform_ellipse_geometry for complete scaling, rotation, mirroring, and affine transformations.
- Clean up tangent parameters in to_render for Ellipse so start_param and end_param are consistently unwrapped.
- Add comprehensive unit tests in transform.rs, block_cache.rs, and ellipse.rs verifying negative rotations, negative scales, and distant origins.
flatten_plan 2,289 -> 1,098-1,144 us (-50..-52%); flatten_scene_apply 1,213 -> 789-813 us (-33..-35% vs baseline; -28.5% same-session O2-vs-O1, drift-corrected).
Pre-sizes collect/plan vectors and adds Scene::update_entities so FLATTEN issues one geometry bump per batch instead of per entity; single update_entity keeps its exact bump-per-call semantics.
Follow-up to 0bfd5dcc:
- A clipped block hatch kept its unclipped plane-local outline, which the
viewport plot projection prefers, so fills bled past the XCLIP boundary
on layouts. Rebuild it from the clipped outline.
- insert_spatial_filter / filter_handle run for every INSERT in each
render walk; resolve the xdictionary through the entity link or the
document index only, and leave the whole-object scan to set_insert_clip.

Paste (and WBLOCK, which shares the kernel) kept the source boundary
handles, so the pasted hatch stayed tied to the original outline or to
unrelated handles in another drawing. The COPY remap now lives at the
document level and runs for both.

Resolve the SPATIAL filter through extension-dictionary fallbacks
(missing xdictionary handle, DictionaryWithDefault, case/whitespace
tolerant keys) so clipped INSERTs no longer plot unclipped. The
inverse-block matrix is used as stored; the codec decodes the on-disk
column-major layout (fixed upstream).
The DWF package reader, the DGN stream inflater and the new DGN
ExtendedColors scan each read a zlib/zip payload to its end, so a
crafted or corrupt file could inflate until memory ran out. Cap them:

- Insert > Reference: the PDF Attach button becomes an Attach Underlay menu
(PDF / DWF / DGN); its face runs the last one chosen.
- DWFATTACH, DGNATTACH and ATTACH on a .dwf/.dwfx/.dgn open the Attach
dialog for that kind: sheets or models with thumbnails (one chosen),
placement, path type, file details with the sheet / model size, and for
DGN the conversion units (sub units offer 1 / sub units per master as the
scale).
- DGN V8 true colours come from the ExtendedColors record packed in the
non-model attributes stream; the colour word's high part numbers them.
- A DGN model's extent includes each text's box (its length along the
baseline and 1.5 x its height), as the reference sizes a model.
- DWFx text uses the family named in its embedded (deobfuscated) font.
- DWF contrast pivots at 0.73 once colours are turned over for a dark
background.
- Hairline strokes are drawn solid one pixel wide, and underlay rasters are
made at or below their size on screen so those lines stay unbroken.

- W2D: a stream cut off right after an extended opcode's '(' sliced its
body backwards and panicked.
- DGN V8: the compound-file header was indexed before its length was
known (a short file with the signature panicked), the sector shift was
taken on trust (0 or 1 underflowed `sector / 4 - 1` into an endless
loop), and the DIFAT chain count was unbounded. The header must now be
complete, the shift 9 or 12, and the chain no longer than the file.

- PDFOSNAP, DWFOSNAP and DGNOSNAP are separate; UOSNAP sets them all and
reads 2 while they differ. Enable Snap switches the selected kind's.
- DWFCLIP / DGNCLIP clip their own kind with the kind's prompts and message;
CLIP routes DWF and DGN underlays there; Enter at a corner asks again.
- The right-edge underlay tools show for DWF and DGN too (import is PDF
only).
- Underlay layers: DGN levels (V8 level table, "Default" listed as "0"; V7
used levels named from the level name table), hidden through the layer
override data with the DGN placeholder string first; a plotted DWF has
none.
- V8 colour read from its colour word (by level, index, or a true colour
drawn as its nearest index); 3D V8 elements drawn in plan (lines, line
strings, ellipses and arcs by their orientation, text); a model's extent
includes its text.
- DWF 6 TrueType text (font, height, rotation from the font opcode) and DWFx
glyph runs are drawn; the default W2D colour map is the measured one.
- Contrast pulls lightness towards a per-kind pivot as measured (PDF 0.5,
DWF 0.243, DGN 0.65).
- Zoom extents includes raster images and underlays whose frames are hidden.

Frames: follow the drawing state, DWF/DGN frames, image frame profile, frame-only picking
The codec [patch] to ramox81/cadcodec@ea5edaa is dropped: that commit landed as opencadcodec#63 and main already pins ad16215, which contains it.
A page shown small was drawn from its full-size raster and thin lines broke
up into dots. Once a zoom settles on another quarter-octave step, PDF, DWF
and DGN underlays are rasterised again near their size on screen (never
above the full-size raster), frames are requested until that happens, and
the adjusted-pixel memo is kept per raster size. V7 element weights no longer
widen strokes, matching V8 models.

DWFATTACH / -DWFATTACH and DGNATTACH / -DGNATTACH attach a DWF / DWFx sheet
or a DGN (V7 or V8) model with the reference's prompts; ATTACH routes the
file types to them. The sheet or model is read into vector paths, drawn as a
transparent underlay raster (contrast, fade, monochrome and background
adjustment apply) and offers its geometry to object snaps. Definitions are
kept in ACAD_DWFDEFINITIONS / ACAD_DGNDEFINITIONS, the External References
palette lists and reloads them, and image textures get line-keeping mip
levels so thin underlay lines stay visible when zoomed out.

An image's transparency flag decides whether transparent pixels show what
is behind the image or draw in their stored colour: the image pass and PDF

TRANSPARENCY selects images and asks for the mode, defaulting to the first
image's current one.

- The Frames list shows the drawing's frame state (hide / display and plot /
display but not plot / frames vary), follows commands, undo and document
switches, and lists the mixed state as a disabled item.
- DWFFRAME and DGNFRAME are frame variables of their own, kept in the header,
and FRAME sets them with the others.
- Out-of-range frame values say "Requires an integer between 0 and 2." and
ask again; a set value reports "Regenerating model.".
- IMAGEFRAME is stored in the image variables as bits (2 is written as 3) and
a drawing without them uses the profile value, which setting IMAGEFRAME
updates and the settings file keeps.
- Raster images, PDF underlays and wipeouts are picked on their frame only;
underlay snap geometry is never picked.

DFKai-SB (kaiu.ttf), MingLiU and other early DynaLab fonts assemble each
ideograph from stroke components that only the TrueType instructions move
into place. ttf-parser's `outline_glyph` returns the raw, unhinted `glyf`
outline, so these fonts rendered with missing or displaced strokes
('自' drawn as '目'; 範, 直, 啟, 動 broken). FreeType calls them "tricky"
and always runs the interpreter for them.
Every non-test `outline_glyph` call site in ttf_glyph.rs (`glyph`,
`outline_char` - shared by both native fallback paths -, the web
`build_fallback`, and both `build_shaped` variants) now goes through
`outline_glyph_into`; `outline_char` takes the font data and face index
for that. When skrifa's `require_interpreter()` says the face
is hint-reliant, the glyph is hinted with the TrueType interpreter
(Target::Mono) at 512 ppem and scaled back to font units (x upem / 512);
every other font keeps the exact ttf-parser outline. The decision and the
HintingInstance are cached once per face, keyed by (byte length, face
index, head.checkSumAdjustment) because fontdb may hand out a new buffer
per call. The hinted path is recorded first and replayed only on success,
so a failed draw falls back to ttf-parser without a half-drawn glyph.
skrifa 0.42.1 is already in the lockfile (via hayro / glifo).

Every glyph advanced by the face's letter spacing, including CJK glyphs a
style's big font or the TrueType fallback supplies. Their advances already
carry the gap (big font) or side bearings (TrueType), so with an LFF primary
such as iso each ideograph took 1.33 heights instead of one.
Face::spacing_after(ch) gives the tracking only to glyphs the stroke font
draws itself; every layout path uses it.
The 1.8-height widths in the report were the TEXT bounds estimate counting
UTF-8 bytes; opencadcodec 1109d52 counts characters.

Inventor DWG exports place every sheet block with AcIdBlockReference,
which the codec skipped, so these drawings opened blank. opencadcodec
7c20aa7 decodes it as an INSERT and keeps the viewport each model-space
view reference is bound to.
Those view blocks overlap in model space, so a content viewport now also
hides model-space references bound to a different viewport. The handles
join the viewport's frozen-layer set (entity and layer handles never
collide), which the wire and render-graph visibility checks and every
per-viewport cache key already use.

Review of #1484:
- The underlay's snap geometry became one hidden wire per segment, but
every piece took the whole page's bounding box, so each cursor move
visited every piece. Each piece now gets its own box.
- Assigning unlayered images to the last layer compared Debug strings of
every layered path and text per drawn item (quadratic, formatted anew
each time); the owners are keyed once in a map.
- The `snap` automation op used (0, 0, 0) for a missing point; it now
answers invalid_point. It also left the live snapper's base point set
to the query's; the base point is restored.

The codec and kernel repositories and crates are renamed opencadcodec and
opencadkernel. Inside OCS they are depended on under short keys, so code
reads `codec::`, `kernel::` and the new `graph::` (opencadgraph, the node
graph engine). File-format and protocol spellings stay as they were: the
ACIS product id `acadrust`, the ACADRUST_* switches and the plugin
version keys `acadrust_version` / `acadrust_source`.
A button left of MCP on the command line opens a translucent node graph
over the viewport, with a palette of object, input, math, logic, list,
text and geometry nodes added by click or drag. An object node owns
drawing entities and its rows are the Properties panel's own rows for
them: the single-object page is extracted from refresh_properties as
entity_property_sections, values use the control protocol's
property_json, and writes go through set_property_value with a property
target override, so the panel, MCP and the graph share one read/write
path. A list reaching an object row makes one entity per element. Each
graph action is one undo step; the canvas pans and zooms.

- An inverted clip's roundtrip record goes in the filter's extension
dictionary through the codec's own API (ensure_extension_dictionary /
xrecord / extension_dictionary_handle) instead of a scan of every
object, which the renderer ran for each clipped reference.
- Pin cadcodec 1c3be0c (the DXF writer now links a spatial filter's
extension dictionary, so that record is not left unreferenced) and
cadkernel deb529b; plugin crates and the Python plugin lock follow.
- The XCLIP boundary preview stays f64.

cadkernel at 4134ae3, which follows it; drop the fork patch, move the
plugin-API and web-worker crates and the Python plugin lock to the same
codec so one copy is built.
- "Import as block" with raster images left IMAGE entities without an
image definition: block definition now creates it like add_entity does,
through one shared helper.
- The three preview outlines (attach frame, clip boundary, import area)
stay f64 instead of casting world points to f32.
- Page size / total / PDF scale entries use the catalog's positional
placeholder; the bare {name} form failed to format in 20 locales.
- The Underlay Layers bulb is the SVG layer icon, not a text glyph.
- PDF dialogs use the shared dialog buttons and radios.
- Options opened from a PDF dialog clears its saved state on return.
- Paper-space underlay background reuses the model block handle already
resolved; dead `let _ = i` lines and a misplaced doc comment removed.
