Older GPUs without usable DirectX 12 Feature Level 12_0 or working
Vulkan support (e.g. legacy Intel iGPUs and other old parts), and old
GLES drivers whose shader compiler rejects iced's own shaders, crash
at startup or on the first drawing viewport: StagingBelt aborts in
Buffer::get_mapped_range (panic=abort, silent exit) on the DX12 path,
and shader compilation fails inside iced's gradient pipeline on the
GLES path. Selecting a working backend via WGPU_BACKEND before iced
boots avoids both classes.
- Probe each candidate backend (Windows: dx12,vulkan,gl; Linux:
vulkan,gl) in an isolated --gpu-probe child: device request,
staging-style mapped upload, render pipeline creation (its fragment
shader reads a private vec4 array, catching old-Mesa compile
failures), offscreen render and readback. First fully-passing
backend wins; explicit --backend / WGPU_BACKEND / --safe-mode
always win, and Windows keeps preferring DX12/Vulkan (#55).
- Software adapters (WARP/llvmpipe/SwiftShader) are the last resort
before a best-effort GL attempt: slow but alive.
- The crash sentinel names the attempted backend so only implicated
backends are skipped next launch.
- Winning probes report adapter limits; GPUs without shader storage
buffers get the packed compatibility renderer automatically, with
a startup command-line notice so the switch is never silent.
Properties… next to the printer used to open the CUPS web interface in a
browser. It now edits the driver options of the *selected* printer the
way LibreOffice's Properties… does, without leaving the plot dialog:
- CUPS platforms (Linux, any desktop; macOS): an in-line editor lists the
printer's PPD options as `lpoptions -l` reports them — media type,
colour mode, quality, duplex, trays, scaling — with readable choice
labels, Reset / Cancel / Apply. Apply keeps only the choices that differ
from the driver defaults, per printer, in the plot config, and every job
for that printer passes them as `lp -o key=value`. Where CUPS cannot
answer, the desktop's printer settings panel opens instead of a browser.
- Windows: the driver's document-properties sheet (`DocumentPropertiesW`
with prompt, owned by the main window) and, on OK, the result stored as
the user's printing preferences for that printer (`SetPrinter` level 9),
which the job honours. `printui /e` (printing preferences) replaces the
device-properties sheet as the fallback.
The desktop print portal was tried first and dropped: GTK 4's print
dialog loses the preselected printer when the default queue is listed
before it, so the dialog always opened on the wrong printer.
Dialog layout: the modal grows to 940×620; Printer / plotter and Paper
size share a line with their pickers (long queue and media names now fit);
Copies + Properties… and Custom… sit beneath; the custom-sheet editor
labels each margin (Left / Right, Top / Bottom) and shows the unit.
Also recognises `none_device`, AutoCAD's stored spelling for "no plotter",
and writes it back unchanged.
Tests: `lpoptions` parsing and keyword humanising, the editor flow (load,
stale answer ignored, set, apply, remember, reset, error, cancel), device
name round-trips including `none_device`.

- IMAGEEMBED: pack raster images into OLE2FRAME entities so a .dwg is
self-contained; 'Embed Image' entry in the XREF attach menu; control/MCP
op embed_image for external tools; dxf_name for OLE2FRAME queries.
- Scene: populate_images_from_document now rebuilds OLE2FRAME and PDF
underlay models too (they used to vanish after any XREF op).
- Printing: add PRINTER_ENUM_NETWORK pass when listing printers; GDI
spooler fallback (hayro raster at 300 DPI + StretchDIBits) for hosts
whose PDF handler registers no print verb; DEVMODE orientation with a
90-degree raster rotation fallback for v4 drivers; fix the fit-scale
precedence bug that printed blank pages.
- PDF export dialogs on Windows use the async file dialog so the native
overwrite confirmation no longer deadlocks the UI thread.
- Plot dialog: persist the chosen printer (saved on selection) and the
picked plot window across sessions; page setups with no device no
longer reset the output device.
- Community fonts: detect unresolvable .shx references on open and offer
a download from the repository's fonts/ folder (contribution guide in
fonts/README.md); custom font source URL setting for intranet font
servers; downloaded fonts resolve from the per-user fonts directory.
Refresh associations after complete SpaceMouse camera updates and recognize imported paper-space owners without Layout objects. Use kernel containment, intersection, perpendicular and spline tangent solving; pin cadkernel 7ce27f2 and add regressions.
Each menu row is now a single mouse_area that publishes on PRESS instead of a button nested in a mouse_area. iced_aw ContextMenu keeps its overlay element in the widget struct, so every view rebuild wipes the overlay subtree state - including a button's is_pressed between press and release - and release-time clicks published nothing. Headless simulator tests through the real overlay guard row clicks, flyout clicks, the Change Path Type hover trigger, and pin the subtree-reset mechanism. Requires iced_test as a dev-dependency; the Cargo.lock gpu-allocator/windows edge is pinned back to 0.62.2 (see docs/review-context-menu-click-delivery.md).
Include decoded IMAGE/OLE content in the shared PDF plotting path,
with clipping, transforms, transparency, draw order, and resource reuse.
Use named page content for export and printing.
Fixes#1266
Populate the plot-dialog printer list from the Windows spooler cache.
Validate record counts and UTF-16 name bounds before reading the buffer.
