This patch makes a few changes to the way we calculate line-height: - `line-height: normal` is now resolved using metrics from the used font (specifically, round(A + D + lineGap)). - `line-height: calc(...)` is now resolved at style compute time. - `line-height` values are now absolutized at style compute time. As a consequence of the above, we no longer need to walk the DOM ancestor chain looking for line-heights during style computation. Instead, values are inherited, resolved and absolutized locally. This is not only much faster, but also makes our line-height metrics match those of other engines like Gecko and Blink.
