{# The index inside a Schuil frame, after the specimen page in the American Specimen Book of Type Styles. Each tile is placed as the specimen placed it, in its units (a pica is 100), and the stylesheet scales the units to the screen. Only brass rule stretches: the frame's fixed pieces sit at the corners and in the middle, and the rule between them takes up the rest. The right half is the left half turned over. A tile with --ax: 1 is placed from the middle of the frame rather than its left edge, and one with --ay: 1 from its foot rather than its head; --m is the tile's turn. #}
