Running snaps only saw a block reference's insertion point. Now the objects
inside it snap where they are drawn: nested references and MINSERT arrays are
expanded, placed exactly by the reference's transform (non-uniform scale
turns circles and arcs into ellipses), and hidden objects or objects on layers
that are off are left out. Insertion also snaps to visible attributes.
