**TEXTFILL marked the drawing modified.** It is an application preference —
it lives in a process global and is snapshotted into settings.json — but it
was missing from the list of names that persist, so setting it dirtied the
open drawing instead and never reached the settings file through that path.
**LTSCALE and CELTSCALE validated differently depending on the door.** The
standalone commands reject a value of zero or less, because a non-positive
linetype scale degenerates every dash pattern in the drawing. `SETVAR LTSCALE
-5` accepted it. A test drives both entry points for both variables and fails
on the SETVAR path without the fix.
**ISAVEBAK, SAVETIME and FILEASSOC were missing from the autocomplete
registry** although all three dispatch, so the command line never offered
them.
**`bg_color` and `paper_bg_color` were dead fields**, always written as `None`
and ignored on load since the model-space configuration superseded them.
Removing them is safe: the config is `#[serde(default)]` and ignores unknown
keys, so existing settings files simply stop carrying them.
One thing the survey flagged that turned out not to be a bug: on the Display
page the model background row hides itself outside Custom mode while the
paper and desk rows do not. That asymmetry is correct — the canvas mode
governs only the model background, and the other two apply in every mode.

Three settings that work, persist, and could only be reached by typing their
name: TEXTFILL, CLIPROMPTLINES and COMMANDLINEFADETIME. The last two govern
how much of the command window is prompt and how long its history lingers —
the kind of thing people fiddle with once and then leave, which is exactly
what a settings dialog is for.
One fix rides along. TEXTFILL is a process-global, so changing it invalidates
the text in every open drawing; the SETVAR path rebuilt only the active tab,
leaving the others rendering the previous setting until an unrelated edit
happened to rebuild them. Both paths now go through
`invalidate_text_everywhere`, so the checkbox and the command cannot disagree.

Options → Selection already carried the pick box, the selection-area effect
and the grip visuals. Four settings behind it were finished, persisted and
reachable only by typing a system variable, and one more was a constant.
**Four that only needed a widget.** `SELECTIONEFFECT`, `SELECTIONPREVIEW`,
`PICKADD` and `PICKDRAG` are all wired end to end already. `SELECTIONEFFECT`
was the odd one: the card's own "Restore Defaults" button resets it, so it
could be turned off by a button and only turned back on from the command
line.
`SELECTIONPREVIEW` is a bitmask and gets one checkbox per bit, which is why
`set_preview_bit` exists rather than two inline expressions — the bits are
the thing this change is most able to get backwards.
The `PICKADD` checkbox is worded as AutoCAD words it, "use Shift to add to
selection", which is the *inverse* of the stored flag. That inversion is
commented at both ends; it reads as a bug otherwise.
**`GRIPOBJLIMIT`.** The limit past which a selection gets no grips arrived
with the selection work as a hardcoded 100, matching AutoCAD's default. It is
now a setting, a slider and a system variable, following `PICKBOX`'s path
exactly. AutoCAD's 0 means "no limit", which the old `>` comparison could not
express, so the read now guards on it — with a test, because zero is the one
value that would otherwise suppress every grip instead of allowing all of
them.
The slider covers 0..=1000, where every useful value lives; the sysvar takes
AutoCAD's full 0..=32767, and a larger value set from the command line parks
the handle at the end while the read-out keeps showing the real number.
**`SelectionPrefs`** replaces the `pick_box` parameter rather than adding
three more. `view_window` already took seventeen positional arguments, and
`pick_add` / `pick_drag_rect` are two adjacent `bool`s that would swap
silently at the call site.
**Two fixes found on the way.** `OPTIONS` and `OP` were registered for
autocomplete but never dispatched, so typing either answered "Unknown
command" and the dialog could only be opened from the start page. And the
`SELECTIONPREVIEW` doc comment had its bits the wrong way round — the code
reads `& 1` for the idle rollover and `& 2` for the in-command one, as
AutoCAD does — which would have put the two new checkboxes' labels backwards.
**Not done, deliberately.** `PICKFIRST` and `PICKAUTO` exist but are always
on, with no variable. `PICKSTYLE` is stored in the header and read by nobody
— group expansion decides from the group's own `selectable` flag — so an
"object grouping" checkbox would control nothing. Associative-hatch selection
does not exist as a selection behaviour. Each needs a behaviour change rather
than an exposure.
Of the ten new strings, en-US and el-GR are translated; the other nineteen
locales carry the English text. Composing them from existing keys, the way
el-GR composes the neighbouring labels, only works for one of the ten —
there is no existing key for "limit", "unlimited", "shift", "rectangle" or
"lasso", and "Grips: Objects" as the label of a numeric limit would be worse
than an untranslated string.

Refresh stale depth bounds after geometry edits, allow orbiting through camera poles, and preserve hidden-line occlusion for selected solids.\n\nFixes #957
Model space appearance now follows the active UI theme instead of a
hardcoded dark background. Canvas mode is user-selectable (Match Theme /
Classic CAD Dark / Custom RGB), with matching controls for the paper
sheet and desk surround backgrounds and grid opacity.
Implements industry-standard CAD system variables, all settable via
command name, SETVAR, and the Options dialog:
- COLORTHEME (0/1 dark/light UI scheme, preserves custom palettes)
- COLORSCHEME (interactive named-theme selection)
- BACKGROUND (THEME/CLASSIC/DEFAULT/DESK presets, RGB triplets)
- SELECTIONAREA, SELECTIONAREAOPACITY (translucent marquee fill)
- WINDOWSAREACOLOR/WINDOWAREACOLOR, CROSSINGAREACOLOR (ACI or theme)
- SELECTIONEFFECT, SELECTIONEFFECTCOLOR (GPU highlight pass, driven by
selection_generation invalidation — no retessellation)
- SELECTIONPREVIEW (bit 0 = idle rollover, bit 1 = in-command hover)
- GRIPSIZE, GRIPCOLOR, GRIPHOT, GRIPHOVER (grip overlay styling)
- Implement `TABLEDIT` command supporting viewport point-picking on cell interiors
- Support overlapping table hit testing with selection cycling and top-table resolution
- Support `/n` and `\n` multiline paragraph breaks (`\P`) in table cell text editing
- Unify text input modes via `InputKind` (`Point`, `SingleToken`, `FreeText`) on `CadCommand`
- Migrate 15+ commands across annotate, draw, insert, layout, and view modules
- Preserve text casing, literal spaces, and bypass arithmetic eval during FreeText input
- Add dedicated `tabledit_tests` and `free_text_entry_tests` test suites
