-/// A buffer that holds tangent vectors.
-///
-/// Tangent vectors are tightly packed in the array.
-///
-/// Tangent vectors have 4 coordinates: (X,Y,Z) for the vector, W for the sign.
-/// The usual rules of MikkTSpace apply, namely that the bitangent should be
-/// computed as:
-///
-///   bitangent = tangent.w * cross(normal, tangent.xyz);
-///
-/// Refer to the MikkTSpace documentation for more details.
-///
-/// The primitive pointer points to the mesh primitive for which the tangents in
-/// this buffer were computed. When your application loads mesh primitives, it
-/// can scan the cgltfTangetBuffer array outputed by cgltf_compute_tangents() to
-/// see whether tangents were computed for the mesh primitive.

-  cgltf_primitive* primitive; // The primitive these tangents belong to.
-} cgltfTangentBuffer;

-/// Compute tangent vectors for normal-mapped mesh primitives missing them.
-///
-/// cgltf_options can be zeroed out but must be non-null.
-///
-/// cgltf_data is the scene previously loaded by cgltf.
-///
-/// out_tangent_buffers is an output array of tangent buffers, one buffer per
-/// mesh primitive for which tangents were computed.
-///
-/// out_num_tangent_buffers is the number of tangent buffers in the output
-/// array.
