Pin Iced 0.15 so dialogs can measure content before distributing the resolved frame across child panels. Keep the web plugin notice compact and non-resizable.\n\nCloses #582
Use the operating system trust store and Windows proxy settings while keeping TLS verification enabled. Add retryable registry errors with copyable diagnostics.\n\nRefs #563
Cancel stale interaction state across space changes and keep live previews and zoom extents in their active paper/model context.\n\nRefs #539\nRefs #540\nRefs #541
Avoid full document, cache, and GPU rebuilds for entity deltas so add, delete, history, selection, and live polyline edits stay responsive on large drawings.
Replace the raw sentinel input with typed CAD lineweight options so special
values display correctly and unsupported values cannot be entered.
Refs #522
Hold edit leases and compare disk fingerprints before replacement so another editor cannot be silently overwritten.
Offer retry, reload, Save As, or explicit overwrite recovery.
Closes#498
Keep resident wires, draw depths, GPU slabs, and edit history incremental across entity changes. Defer rollover work to avoid cursor jumps on dense drawings.
Replace full-document snapshots with Arc first-touch deltas and batch cache invalidation. Reuse interaction and GPU category caches across unrelated edits.
The embedded DWG preview was the whole drawing fit to a canvas, encoded
as a 24-bit uncompressed DIB (~180 KB at 256²) — the bulk of the gap
between an OCS-saved file and AutoCAD's. Three changes:
- Frame it like the screen. `from_scene` now projects every wire vertex
through the live camera into a viewport-aspect canvas, so the thumbnail
is the current pan / zoom / rotation and only the visible region, not
the full extent. Off-screen / clipped segments don't draw (a `None`
projection or NaN separator breaks the polyline run). Works for any
view. `stamp_thumbnail` passes the model pane's pixel size and the
target version.
- PNG for R2013+ (AC1027+). A line drawing on a flat background is almost
one colour, so PNG collapses to a few KB. PNG previews are only valid
from R2013, so older targets keep a BMP.
- BMP is now 8-bit palettised, BI_RLE8-compressed (was 24-bit raw). The
long single-colour runs of a preview compress to a handful of KB; a
view with >256 colours (rare) falls back to the 24-bit DIB. A full
256-entry palette is written so the reader's `(1<<bpp)*4` pixel-data
offset lands correctly.
Net: the preview drops from ~120 KB to ~2-5 KB on every version.
