We currently have the following values for dominant baseline: auto | text-bottom | alphabetic | ideographic | middle | central | mathematical | hanging | text-top

Can any of these be dropped? Are there any missing baselines that we need?

I just dumped the base table for Adobe Devanagari Regular. I could find no evidence of a metric for a hanging baseline. Does any commonly-used font have such a baseline?
