* Print: flatten transparent sheets for GDI (v3) printer drivers Windows sends a job for a GDI (v3) driver through its XPS-to-GDI conversion, which fails on soft masks (#6155), prints halos around them (#5838) or prints transparency as black boxes (#5940). XPS (v4) drivers print the same pages correctly. spooler_copy takes a flatten_transparency flag. With it, after greying and before tiling, each sheet that uses transparency is replaced by an opaque picture of itself (spooler::flattened): rendered at 300 dpi, lower for a sheet past 80 MP or 16000 px a side, in tiles of at most 2000 x 2000 px, each an RGB Flate image over white, so no tile reaches Windows' 2^22 px image cap and tiling leaves them alone. The sheet keeps its boxes and rotation; its group and annotations go. Sheets without transparency stay vector. pdfcraft-preflight gets page_uses_transparency, the PDF/A transparency search without counting a transparency group on its own, which Word puts on every page. Both callers pass false until the GDI-driver check lands. * Print: flatten transparent sheets only for a GDI (v3) printer driver spool::xps_driver / spool::gdi_driver read whether the printer's driver renders XPS itself, through craft-print's new xps_driver (storytold/craft-libs#804, winprint storytold/winprint.rs#21). The Print dialog and doc_print pass gdi_driver to spooler_copy's flatten_transparency, so XPS (v4) drivers, PDF printers among them, keep vector sheets. craft-print pinned to the craft-libs#804 branch, winprint to #21's, until they merge. * craft-print 60ede99985ef1e5df87a2aca66ed538eb23dec99: craft-libs main with #804 (xps_driver), winprint bc06a7c4 (#21) * Cargo.lock: the two winprint entries in Cargo's order (by source, after the re-pin)
