The redaction proof now reads a font's /ToUnicode with its /DecodeParms given by reference, and `Metrics::from_dict`, which redaction takes the removed text from, read it only with direct ones. Behind a predictor so described, the two got different text for the same codes, so a copy the redaction rightly left counted as a survivor and the proof failed a sound redaction (`a_unicode_map_behind_parameters_given_by_reference_is_read_alike`). Every stream `from_dict` reads now goes through `Document::with_direct_parms`: the /ToUnicode; a composite font's /Encoding, which sets how its codes split (`cmap_streams_read_their_parameters_given_by_reference`); a subset's program and /CIDToGIDMap, which say which of its CIDs have a glyph (`a_subsets_program_and_cid_map_read_their_parameters_given_by_reference`); and the program a simple font without /Widths is measured with (`a_font_without_widths_measures_with_its_embedded_program`). Read without them, as on `main`, such a font was measured with widths guessed from its name, so redaction removed glyphs the mark doesn't cover and left some it does, and the proof, which also guesses from the name, passed. Redaction now measures such a font with its program. The proof still guesses, so it fails that redaction, as it already does on `main` when the program's parameters are direct.
