Publisher — pinning / float: Add vertical align to Baseline + x-Height

[Viktor CR]

For typography aligned layout,
it is often required to continue a line in a pinned frame's first line

• sometimes aligned to the Baseline
  
• sometimes to the x-Height (for optical alignment with the typo)
  

Currently, "Inside Top" (to address the alignment of the frame's first line) aligns to the top of a line.

To get the baselines aligned, one can use an offset of the font size of the line, that the frame is pinned to,
however when that size changes after the fact, the alignment is ruined and all frames aligned in this manner would need tedious manual reworking.

Please add the options

• Baseline and
• x-Height

to the "Vertical Align" dropdown in the Pinning panel.
