	uint32 indices tightly packed (3 * facet_count).

std::vector< uint32_t >	face_materials
	Optional per-face chart ids (size == face_count) forwarded to xatlas as `faceMaterialData` to pin input islands to charts.

uint32_t	vertex_count = 0
	Number of UV "vertices" (= number of unique indexed UV values).

uint32_t	face_count = 0
	Number of triangles.
