* craft-affinity: bounded reader for native Affinity documents, moved from VectorCraft The reader of .af, .afdesign, .afphoto and .afpub files (archive, object stream and document model) as it is in storytold/vectorcraft at 6e873b80 (crates/affinity), under a neutral name. Its corpus tests read the pinned public documents scripts/fetch-affinity-corpus.sh fetches. * craft-affinity: fold in what only PhotoCraft's copy of the reader had From storytold/photocraft at 63b641b5 (crates/affinity), onto the VectorCraft copy: - Special shapes: clouds, hearts, cogs, callouts, arrows, double stars, tears, crescents, diamonds and segments come in as their own outlines, not their bounding ellipse. - Null slots of object lists are charged to the document's work before a list is scanned, on every visit of a shared object (children, attachments, effects, compound operands, page lists, paint lists, gradient colours, text blocks and runs, table cells, tile lists). - A colour or gradient position record is decoded only as far as its components are read. - 16-bit and 8-bit planes are interleaved through tables, not an f64 for each pixel. - Limits::max_pixel_bytes: the caller sets what the pixel layers of one import may hold. - Pixels::cmyka8_to_rgba8 for a caller without colour management. The crate README and docs describe the model on its own terms. * craft-affinity: a callout with a right-to-left box no longer panics; an oversized shape imports as its box Ported from storytold/photocraft#10473 by DJHoltkamp. A callout rectangle clamped its tail with clamp(x0, x1), which panics when the box is stored right to left. A box with finite corners whose size overflows gave infinite or NaN outline points; it now imports as its box with a warning. Also drops the inflated doc.dat once it is parsed.
