This just removes a random subset of vertical writing mode bits that I grepped for. There's a ton more to do, but it seems best to do it in chunks. The key things for understanding this patch, isWritingModeRoot is always false and isHorizontalWritingMode is always true. Also, we're never flipped* modes of any kind, so we can undo any flipping.
