Inputs are the fitted shape parameters for the non-empty sets only,
in the order eulerr stores them (x$shapes rows after dropping rows
with NA). The leading shape argument selects which per-set columns are
active: "circle"/"ellipse" consume (h, k, a, b, phi),
"rectangle" consumes (h, k, width, height), "square" consumes
(h, k, side). The remaining vectors must still be provided (NaN
padding is acceptable). When container_* are non-NULL they describe
the fitted universe-box rectangle; in that case the result also carries
the complement region geometry (the area inside the rectangle outside
every shape) and a label anchor for it. Eunoia's decompose_regions
emits this region under the empty Combination whenever the spec
carries a complement and a container is supplied.
