One facet's share of a mark, and where on the canvas it was drawn.
A faceted plot nests each facet's elements in a translated <g> inside the
mark group; an unfaceted one puts the elements directly in the group. Both
come back through here, the second as a single facet whose offset is zero,
so callers need no special case.
