* Add craft-figma-rest: a typed model of the Figma REST file JSON The neutral model for design files: the .fig and .sketch readers map onto it and an application's importer takes it. Typed records for the document tree, paints, effects, text styles, layout grids, constraints, export settings and the component and style metadata; every record keeps the fields it has no name for, so a file read and written loses nothing. The vectorNetwork extension is typed and documented with the others. The layer tree is converted level by level in both directions, and the depth and node limits are checked on the JSON before any typed value is built. * craft-figma-rest: Warnings and style_name for the readers that build this shape Moved from FigCraft's REST importer and .fig reader (crates/format/src/rest.rs Warnings, fig.rs style_name), which the .fig and Sketch mappings share. * craft-fig: map the message onto the REST file JSON FigCraft's .fig mapping (crates/format/src/fig/map and fig/text_path.rs at e8b53e33) moved onto craft-figma-rest: rest::to_rest turns a decoded message into the REST API file JSON, with the vector networks layers name by vectorNetworkRef handed over beside it. Connector routing and the text path measure check are the caller's geometry (rest::Geometry; rest::Straight when it has none). The plugin data key under which a writer keeps an outlined stroke is an option. The geometry blob is read with craft_fig::path instead of a second decoder. * craft-fig: an empty overriddenSymbolID is no swap The empty GUID (4294967295:4294967295) in overriddenSymbolID means "no swap". The mapping took it as the main, found no node and made the instance an empty frame; it now keeps the main its symbolData names, in the instance mapping and in the list of mains a file's instances use. Ported from storytold/figcraft#2208. * craft-fig: a swapped nested instance takes its new main's look A nested instance swapped to another main stores the previous main's look on its own node, so the mapping drew that. Each group of the look (fills, strokes, stroke settings, effects, corners) whose stored values are a copy of the previous main's now takes the new main's; a group the node or a row above it changes is kept, and a style link is decided by the topmost layer that names it. Ported from storytold/figcraft#2204 (the fig/map part; the warning's locale entry stays in the app). * craft-fig: a vector point without a corner radius of its own takes the layer's A point whose style sets no cornerRadius, or that has no style, takes the layer's cornerRadius, as the file draws it; a point's own value (an explicit 0 included) still wins. The layer's radius is part of the network cache key, so an instance overriding the radius doesn't share its main's network. Ported from storytold/figcraft#2115 (the fig/map part; its export change stays in the app). * craft-fig: map deep files within a 1 MiB stack The mapping recursed once per level of layer nesting in a frame of about 2 KB (an unoptimised build): 300 nested frames, or a chain of instances of mains holding each other, overflowed a 1 MiB stack before the 256 level limit could stop them, a crash on hostile input. The work on one layer now happens in layer_head and layer_tail, which return before and after its children are mapped, and what they hand over is boxed, so the recursive frame is about 800 bytes. An unoptimised build now maps past the limit on 512 KiB; the limit stays 256. The test at the limit runs on a 1 MiB thread, for frames and for instances, and overflowed before this change. --------- Co-authored-by: Trevor Brown <trevorbrown.dev@gmail.com> Co-authored-by: Giovanni Almeida <gioalmeida07@gmail.com>
