This is a first (huge) step towards modernizing the layout architecture and bringing it closer to spec language. Layout is now performed by a stack of formatting contexts, operating on the box tree (or layout tree, if you will.) There are currently three types of formatting context: - BlockFormattingContext (BFC) - InlineFormattingContext (IFC) - TableFormattingContext (TFC) Document::layout() creates the initial BlockFormattingContext (BFC) which lays out the initial containing block (ICB), and then we recurse through the tree, creating BFC, IFC or TFC as appropriate and handing over control at the context boundaries. The majority of this patch is just refactoring the old logic spread out in LayoutBlock and LayoutTableRowGroup, and turning into these context classes instead. A lot more cleanup will be needed. There are many architectural wins here, the main one being that layout is no longer performed by boxes themselves, which gives us much greater flexibility in the outer/inner layout of a given box.
