feat(glb): a loader for binary glTF, and images decoded from memory - Crafter.Asset:GLB. GlbAsset::Load reads a .glb from a file or a buffer: - nodes, with their parents; - every mesh's primitives: positions, normals, UV0, tangents (computed when absent), joints, weights (normalized), u32 indices; - skins with their inverse-bind matrices; - materials: PBR, emissive strength, transmission, ior, alpha mode; - images decoded to RGBA8, and samplers; - cameras and KHR_lights_punctual lights; - the raw JSON, and the extras of the scene, nodes, materials and lights. nlohmann/json 3.12.0 is vendored in lib/; only the implementation sees it. - A broken file comes back as an error rather than a crash: - bad magic, truncation, a sparse accessor; - a chunk, view or accessor past its bounds, checked so that nothing wraps round, with 32-bit size_t too; - a stride outside 4..252, or one its elements overlap in; - a reference to something that doesn't exist, or children that form a cycle (found stepping through each node once, however deep); - a path that isn't a file; - an image larger than a texture's 65535 a side. - TextureAsset::LoadPNGFromMemory decodes an image already in memory. LoadPNG refuses images over 65535 a side instead of truncating their size (in its float path, past the end of the pixels). - Tests: GLB.
