An EPS saved for Illustrator 10 keeps its type in the editing data as
legacy text objects (`To` ... `TO`), with no `/AI11Text` slot for the
page's type to go in, so a file whose page had text came in as its page.
Those text objects are now the layers' own: the page's type isn't put
anywhere, and the comparison with the page decides as before. Type the
editing data keeps only as outlines stays outlines, with a note counting
the page's text objects that are.
