deckcraft-metafile (still kurbo + thiserror only, so it builds for wasm): - Text: WMF EXTTEXTOUT/TEXTOUT and EMF EXTTEXTOUTW/EXTTEXTOUTA/SMALLTEXTOUT with the selected font (CREATEFONTINDIRECT, EXTCREATEFONTINDIRECTW: face, signed LOGFONT height, width, weight, italic, underline, strike-out, escapement, charset), text and background colour, background mode, TA_* alignment and TA_UPDATECP, the dx array (ETO_PDY pairs too), ETO_OPAQUE fills and ETO_CLIPPED clips. 8-bit strings decode through their charset (Windows-1252/1250/1251; symbol fonts keep their codes at U+F000; double-byte sets keep their advances). The neutral Item::Text carries a text-space-to-picture transform, so the mapping and escapement are folded in and glyphs are never mirrored. - Brushes: WMF DIBCREATEPATTERNBRUSH, EMF CREATEDIBPATTERNBRUSHPT and CREATEMONOBRUSH, and BS_HATCHED, as Item::Pattern tiles in 96-dpi pixels; WMF PATBLT. The XOR / AND-pattern / XOR see-through shadow of old PowerPoint WMFs draws its pattern in the XOR colour. - MFCOMMENT escapes with an embedded EMF are ignored: PowerPoint draws the WMF's records. - Pattern pixels and text count against the byte budget; strings are capped. deckcraft-render draws text through deckcraft-fonts with the face slide text would use (document_face), symbol fonts mapped as bullets map them (deckcraft_text::symbol_char, now public, with Webdings), per-character fallback, the file's advances, GDI cell metrics for top/bottom alignment, underline/strike-out and synthetic bold/italic. Tiles below 1.5 output pixels per cell are drawn as their average colour. On the 24 corpus slides that show a metafile, mean abs diff against PowerPoint goes from 28.31 to 5.06 (with the OLE/ActiveX preview commits).
