STLOUT/STEPOUT wrote via std::fs and IMPORTOBJ read via std::fs, all
of which fail on wasm32. The export pickers now mirror the PDF path
(pick_*_owned returns a name-only PathBuf; the browser download names
the file) and the write tail swaps fs::write for sys::download_bytes.
OBJ import reads the picked file's bytes directly, like the web open
picker.
Opening by drag-and-drop was dead on the web build: winit never emits
FileDropped there. A wasm-gated io::web_drop module installs DOM
dragover/drop listeners, filters .dwg/.dxf, reads the File bytes
async, and queues them; the existing 50 ms PollWebControl tick drains
the queue into the same open path the picker uses (progress overlay,
recovery, OPFS recent cache).
Also floors the model-space plot sheet: extents smaller than 10 mm
(or the 0x0 paper a fresh unsaved drawing carries) now fall back to
the standard sheet instead of producing a ~3 pt page.
- pdf_export: drop the stale wasm32 gates (printpdf 0.9.1 compiles for
wasm; the memchr/lopdf incompatibility is gone with memchr 2.8.3).
Rendering is portable via render_pdf_bytes; only persistence differs:
atomic temp-file write on desktop, browser download on the web.
pick_pdf_path_owned on wasm returns a virtual path so the existing
message flow works unchanged.
- printpdf moves from the native-only dependency table to the shared one.
- print_to_printer: preview_page_pdf / preview_pages_pdf render the same
bytes and open them in a browser tab on the web (the browser's print
dialog takes over); desktop keeps the temp-PDF + OS-viewer flow.
- sys: open_bytes_in_new_tab (blob URL, popup-blocked falls back to a
download).
- New PlotQuality preset caps embedded raster resolution (High = native,
Normal = 300 DPI, Low = 150 DPI effective); vector output is untouched.
The image resource cache keys on the post-resample dims so one pixels
Arc placed at different effective DPIs embeds per-placement XObjects.
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.
