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
Replace manual key entry with per-row capture cells: clicking + Add
inserts a draft row at the top with its key cell armed, and the next
key combination is recorded and normalized (Ctrl+Shift+S →
CTRL+SHIFT+S). While armed, a dedicated keyboard listener swallows all
input so recorded shortcuts do not execute in the drawing.
Draft rows are transient and confirmed only through an explicit accept
button, so the table never retains empty rows. Duplicate keys and
unrunnable commands are flagged in danger styling with a persistent
warning naming the conflicting command. Added reset-to-defaults with
confirmation, apply-and-exit, a shortcut count, and an unsaved-changes
guard on close.
Keep hidden pre-drag geometry out of snap candidates and avoid empty
scene invalidations. Require stable OTRACK dwell observations and cache
planar-solid visibility during live previews.

Extract the push-undo → per-handle → invalidate → dirty → refresh
contract into one helper on OpenCADStudio. The helper is the single
source of truth for property-op side effects, so future property
handlers can't forget the cache invalidation or the panel refresh.
Note: MATCHPROP now no-ops when the destination selection is empty
(previously it marked the tab dirty and refreshed the panel). This is
a minor correctness improvement; restore the old behaviour with a
2-line guard at the MATCHPROP call site if desired.

Sync current main and companion codec changes before preserving unsupported frame rows, rendering in the entity plane, and sharing final layout metrics with placement preview.
INSERT enumerated all block names in a single prompt string, causing unbounded overlay growth and full-screen occlusion in drawings with many blocks. Replace prompt enumeration with a ranked, incrementally filtered suggestion model: BlockPicker maintains precomputed lower/upper caches and usage ranks (MRU/frequency), filters via O(n) substring scan and partial sorting (select_nth_unstable) to O(k), bounded to CLIPROMPTLINES.
Introduce CLIPROMPTLINES (Integer 0-50, Registry, default 3) for the number of temporary prompt lines above the command window; persist in UserSettings, expose via SETVAR and direct entry, enforce in CommandLine::view. Suggestion count is in direct relation to CLIPROMPTLINES (limit = clip, capped to 50).
Make search live without requiring Enter: add CadCommand::on_live_input, implement for INSERT/MINSERT via picker.set_needle, and wire to command-line input paths (Message::CommandInput, on_command_append_char, on_command_backspace). Updates use upper/lower caches and partial sort for <0.2ms per keystroke on 10k blocks, with debounced block-usage persistence (MRU cap 20, freq cap 200) to avoid I/O thrash. Correct tri_count test helper to use display_from_solid.
