Previously individual strokes were represented by distinct mesh objects no matter how many vertices and materials each stroke has, although the vertex and material counts can be quite small depending on the input scene data. Now stroke meshes are packed into a minimum number of mesh objects, so as to reduce the overheads of Blender object creation.
