M10: Print ▸ Properties… opens the printer driver's own settings (#482)

* M5.7: date format and date language for Fill & Sign in the engine * M5: flatten Fill & Sign marks when saving Saving can now bake typed text, marks and signatures into the page, from Preferences or doc_save. The option defaults off, so a normal save still leaves them editable, and other comments and form fields stay. * M4: zoom the Organize page grid The page grid draws its pages at 50% to 300%: toolbar buttons with a percentage that resets to 100%, trackpad pinch or Ctrl/⌘ + wheel about the page under the pointer, and ⌘+ / ⌘− / ⌘0 (which no longer change the hidden page view's zoom while the grid shows). Thumbnails are re-rendered sharper in a few steps as the grid grows, capped so one document's thumbnails stay within 256 MB. The page under the pointer (or the first one in view) stays where it is across a zoom. Co-Authored-By: Claude Opus 5.5 <[email protected]> * M4: zoomed grid pages are rendered at the size drawn A zoomed page grid stretched 132 pt thumbnails, and the stepped detail that was meant to help was capped by a memory budget, so a long document stayed blurry at any zoom. Pages drawn larger than their thumbnails now get a render at exactly the size drawn while they are in view; the thumbnail stands in until it arrives. Only pages in view keep one, so memory no longer depends on the page count, and thumbnails go back to their one fixed size. Co-Authored-By: Claude Opus 5.5 <[email protected]> * M5.7: fill_sign_date_format tool; format and language on fill_sign_add * M5.7: Preferences ▸ Date format for Fill & Sign dates (refs #158) * M5.7: refuse Fill & Sign dates the PDF text font can't hold * M5.7: Spanish labels for Preferences ▸ Date format * M10: Print ▸ Properties… opens the printer driver's own settings CUPS: the queue's PPD job options (with lpoptions defaults), grouped in the Print dialog and sent with this job as lp -o key=value; installable options and what the dialog sets itself are left out. Windows: the driver's Printing Preferences window through printui (no unsafe FFI), saved as the printer's per-user defaults. Headless: printer_options tool and doc_print options. Co-Authored-By: Claude Opus 5.5 <[email protected]> * View: the middle button pans instead of drawing with markup tools egui's drag responses accept every pointer button, so on Windows and macOS a middle-button drag reached the page tools: with Draw (ink) selected it drew a stroke, and other tools cropped, selected or moved. Linux was unaffected because its middle-click auto-scroll already blocks page input. Outside Linux a middle-button drag that starts in the viewport (document or Organize Pages) now pans 1:1 while the button is held, with a Grabbing cursor, and page input is blocked from the press through the release. Linux keeps its latched auto-scroll. Co-Authored-By: Claude Opus 5.5 <[email protected]> * M3: a short page gone to from the Pages panel stays current The current page was whichever page showed most of itself. Going to a short page (a cheque) above a tall one scrolls it to the top, where the tall page below shows more, so the current page and the Pages panel's highlight moved to the tall page instead of the one clicked. The page navigated to now stays current while it is wholly on screen. Co-Authored-By: Claude Opus 5.5 <[email protected]> * M4: page operations from the Pages panel: context menu and drag to reorder Right-clicking a thumbnail offers Extract pages, Cut, Copy and Paste after, on the selection or on the page clicked (which becomes the selection), as the organize grid does. Dragging thumbnails moves the selection, or the page grabbed, to the gap it is dropped on: a bar marks the gap, the page count follows the pointer, and the panel scrolls near its edges. The move is one undoable step; the moved pages stay selected and the current page follows its page. Documents that forbid assembly keep click-only thumbnails. Parity: view.thumbnail-context-ops is shipped, with what it still lacks. Co-Authored-By: Claude Opus 5.5 <[email protected]> * Pages panel: only the primary button drags thumbnails; a drag left over after the panel closed or the document changed is dropped * Fill & Sign dates: German, Bulgarian, Hungarian and Ukrainian month and weekday names, matching the interface languages * uk: keep the author's wording for the flatten setting --------- Co-authored-by: KissT <[email protected]> Co-authored-by: Mark Bartalos <[email protected]> Co-authored-by: samehelhawary <[email protected]> Co-authored-by: Claude Opus 5.5 <[email protected]> Co-authored-by: Cody Vogt <[email protected]> Co-authored-by: William Max & Co. <[email protected]> Co-authored-by: Brandon Thomas <[email protected]>

This removes the artificial surface ceiling behind a mixed-DPI Windows startup crash when opening Outlook PDF attachments. Synthetic regressions cover the observed 8600 × 3423 surface, downlevel adapters and preservation of other device limits.

The grid gained a "+" at every gap that inserts files right there, and on desktop files dropped on the grid go to the gap under the pointer; Insert from file now takes several files in order, converts images and text, and selects what it inserted. File-type detection moved from the shell into `pdfcraft-create` (`source_kind`), with one engine entry point (`Session::convert_to_pdf`) shared by Open, Insert, Create and the new `doc_create_multiple` tool (which can also write one PDF per file).
