Inline layout is now done by LayoutBlock. Blocks with inline children will split them into line boxes during layout. A LayoutBlock can have zero or more LineBox objects. Each LineBox represents one visual line. A LineBox can have any number of LineBoxFragment children. A fragment is an offset+length into a specific LayoutNode. To paint a LayoutBlock with inline children, we walk its line boxes, and walk their fragments, painting each fragment at a time by calling LineBoxFragment::render(), which in turn calls the LayoutNode via LayoutText::render_fragment(). Hit testing works similarly. This is very incomplete and has many bugs, but should make it easier for us to move forward with this code.
