Bring the names of various boxes closer to spec language. This should hopefully make things easier to understand and hack on. :^) Some notable changes: - LayoutNode -> Layout::Node - LayoutBox -> Layout::Box - LayoutBlock -> Layout::BlockBox - LayoutReplaced -> Layout::ReplacedBox - LayoutDocument -> Layout::InitialContainingBlockBox - LayoutText -> Layout::TextNode - LayoutInline -> Layout::InlineNode Note that this is not strictly a "box tree" as we also hang inline/text nodes in the same tree, and they don't generate boxes. (Instead, they contribute line box fragments to their containing block!)
