Here's roughly how this works: - InlineLevelIterator keeps a nesting stack of inline-level nodes with box model metrics. - When entering a node with box model metrics, we add them to the current "leading metrics". - When exiting a node with box model metrics, we add them to the current "trailing metrics". - Pending leading metrics are consumed by the first fragment added to the line. - Pending trailing metrics are consumed by the last fragment added to the line. Like before, the position of a line box fragment is the top left of its content box. However, fragments are placed horizontally along the line with space inserted for padding and border. InlineNode::paint() now expands the content rect as appropriate when painting background and borders. Note that margins and margin collapsing is not yet implemented. This makes the eyes on ACID2 horizontally centered. :^)
