Long description of illustration 'Adjacent Edges with Inline-stacking, continued'

This diagram illustrates case 3d. Four adjacent glyph areas (three Roman letters and a space A) followed by a inline area P containing Arabic glyph areas, the leftmost of which is labelled B. The right edge of A and the left edge of B are outlined. The diagram also shows a tree view of this structure. The root node has five children: the three Roman letters, the space and the Arabic word. The latter is itself a node containing each Arabic glyph, in document order, i.e. reversed from rendered order.
