- 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.

An image background not fitted to the screen keeps its own pixel size
(times its scale), centred on the viewport and moved by its offset, as
the reference draws it; tiling repeats it from there.

Measured against the reference: a two-colour gradient reaches its end
colours a viewport beyond the edges, and the bands blend linearly.

The rotation is stored in degrees and turns the bottom-to-top direction
counter-clockwise, measured in pixels; a two-colour gradient blends from
the bottom colour to the top one across the whole viewport.

Restoring a named view gives the model viewport the view's visual style
(the closest render mode), and a 2D wireframe viewport shows no
background, as in the reference.

Color, Gradient and Image at the background prompt open a Background
dialog (None / Solid / Gradient / Image, preview, solid colour, two- or
three-colour gradient with rotation, image file with position and
scale). Apply links the view to a new background object in
ACAD_BACKGROUND; restoring a view gives the model viewport a copy of
it (or none), and saving a view copies the viewport's background.

The missing-fonts list is as wide as its longest name, so its scrollbar
was drawn over the end of every name ("ROMANT.sh").

Their grip code already works in world space, and the dispatch layer
converted the grips through the OCS a second time, so for a normal of
(0,0,-1) the grips (and grip edits) were mirrored across the Y axis.

A polyline with a thickness but no width is drawn as its extrusion edges
alone, and those edges were forced black (the outline colour meant for the
filled tube of a wide polyline). On a dark background the polyline looked
black and changing its colour did nothing. Only a wide polyline's tube
edges are black now.

The two dock tests that build and drive the real view overflowed a
default test thread's stack, and made in parallel their headless
renderers crashed the test process about one run in three.

EXPORTSVG left the plot dialog's SVG device on, so a later EXPORTPDF still
offered a .svg file. The SVG save dialog and plot button texts had no
catalog entries.

#1707 took any snap name typed at a point prompt as an override, so a
prompt offering Center, Tangent, Parallel or None (ARC, ELLIPSE, CIRCLE
TTR, ...) could no longer be answered with that option's name. An option
the prompt offers now wins. The point-step test it copied from MTP is one
helper shared by MTP and the override on both input paths.

#1713 dispatched a captured SPACE as a shortcut whenever it was rebound,
so with SPACE on FINALIZE a space typed into any other text field (layer
names, Properties, find) also ran FINALIZE, and the space it typed stayed
in the command line. Ask whether the command input has focus before
running the binding, and drop the space the field already inserted.

#1692 limited no-trim FILLET to two lines and refused arcs and polyline
segments, which #1558 already filleted without trimming (only the arc is
added). It also turned T/N at the object prompts into silent toggles, so
the Trim option no longer reached its Trim/No trim prompt and the choice
was not saved. Keep the arc bookkeeping it added (the new arc can be
picked next, and stays on the picked layer), restore every pair and the
Trim prompt.
CHAMFER's new no-trim mode starts from and saves the same TRIMMODE value
as FILLET instead of always starting trimmed.

#1688 accepted any degree (falling back to 3 on a malformed value) and
overwrote the degree the codec had clamped to the control-point count, so
a two-point default spline stored degree 3 against a degree-1 knot vector.
Reject a non-integer or out-of-range degree, too few control points for
the degree, a knot vector that is not control_points + degree + 1
non-decreasing values, and weights that are not one positive value per
control point.

#1666 sets group 295 on extrusion history records, which makes the kernel
read the embedded profile and path where they stand and ignore the
matrices. The planar fallback profile (a region-derived LWPOLYLINE) was
stored in its plane's local frame with the frame as matrix, so with the
flag it rebuilt at the origin. Re-express it in its own OCS (normal and
elevation) when the record is built.
Pins the kernel and graph at upstream (opencadkernel#84 merged as f051138)
instead of the ramox81/cadkernel [patch].

#1681 places a dimension's picture block by its insertion point, rotation
and scale. Edits (move/rotate/scale/mirror, copy, paste) transform the
picture's sub-entities in world space, and the codec's dimension transform
moves the insertion point too, so a rotated or copied dimension would get
the placement applied twice. Fold the placement into the subs before the
edit and leave the dimension at the identity placement afterwards.
The picture insert no longer takes the dimension's extrusion: OCS bakes
picture sub-entities in world coordinates, so only the stored insertion
point goes through the OCS. A zero insertion-scale component counts as 1.

The informational clippy job fails on two pre-existing literals
(also failing on main, surfaced on this PR's merge): the trim
tangency test's angle list used 3.14 where pi was meant — use the
constant; the point-cloud light-direction fixture in render.rs uses
a hand-tuned 0.318 component that only looks like 1/pi — keep the
tuned value and allow the lint on that statement.
Resolve conflicts from main's rustfmt pass by taking main's versions of
command.rs, style.rs, view/mod.rs, scene/mod.rs, ui/window/mod.rs and
ui/properties.rs and re-applying this branch's Graphic Attributes changes.
Add the Graphic Attributes strings to the new lo-LA catalog.
