We now distribute the line-height evenly between the space above and below inline-level boxes. This noticeably improves our baseline alignment in many cases. Note that the "vertical-align: <length>" case is quite awkward, as the extra height added by the offset baseline must count towards the line box height. There's a lot of room for improvement here, but this makes the buckets container on Acid3 show up in the right place, with the right size.
