eot() only refused fsType 0x0002 exactly, so 0x0003 (which
FontFace::restricted_licence and file.package already treat as
restricted) and Bitmap embedding only (bit 9, e.g. 0x0200, 0x0208) were
embedded with their glyf outlines. Reuse restricted_licence and also
refuse bit 9, matching VectorCraft's Package (storytold/vectorcraft#782).
New designcraft-pptx crate (L3) and file.exportPptx command (File ›
Export PowerPoint…, CLI --export x.pptx). Each page becomes a slide of
native objects: shapes with fills, gradients, strokes and effects,
pictures cropped like their frames, native tables, and text boxes.
Text keeps DesignCraft's composition by default: composed lines end in
line breaks, justified spacing becomes character spacing, and leading
becomes percentage line spacing (PowerPoint rounds exact spacing to
whole points; its 100% line is 1.2 em for every font). Threaded
stories split at their frames and wrapped lines get their own boxes.
lineBreaks: reflow writes one box per frame in native columns instead.
TrueType fonts are embedded as Embedded OpenType when their licences
allow. Objects PowerPoint can't represent (placed PDF/EPS, type on a
path, some effects) are rasterised through the existing
rasterize_where path.
Checked in PowerPoint for Mac and LibreOffice: on the sample magazine,
word positions match DesignCraft's PDF to within 0.8 pt horizontally
and 1.6 pt vertically.
