There are several cases where an Action might have
subsettable content, e.g. text, or referenced

Generally, at the metafile renderer, all actions are
'flattened' out, i.e. a meta action rendering the
string "Hello" counts five indices, and a transparent
action containing a metafile with 100 actions counts
at least 100 indices (contained transparency or text
actions recursively add to this value). From the
