[css-inline] which baseline values are required? #859

Open

Description

@dauwhe

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?

    <BASE>
        <Version value="0x00010000"/>
        <HorizAxis>
          <BaseTagList>
            <!-- BaseTagCount=2 -->
            <BaselineTag index="0" value="ideo"/>
            <BaselineTag index="1" value="romn"/>
          </BaseTagList>
          <BaseScriptList>
            <!-- BaseScriptCount=4 -->
            <BaseScriptRecord index="0">
              <BaseScriptTag value="DFLT"/>
              <BaseScript>
                <BaseValues>
                  <DefaultIndex value="1"/>
                  <!-- BaseCoordCount=2 -->
                  <BaseCoord index="0" Format="1">
