I consider what you describe as preprocessing that must be completed before any layout can take place. After the preprocessing, you're left with a stream of character glyphs, each with its own metrics adjusted in accordance with the special relationships you describe. At this point you can consider a glyph the same as any replaced, inline element, with intrinsic dimensions and zero margins. David Perrell
