IIUC we have never made direct use of the 0 base within a font. Rather, we take
the font's total height --between ascent top and descent bottom (font designers
choice with M hight plus any *internal* leading above or below) and that height
is what is alligned TOP, CENTER or BOTTOM.

Meaning that any two fonts with different metrics will ALWAYS allign
differently--there is no common base line extracted from font(s).

Try it with an exaggerated font like Styx Two.

Short of a rewrite of VCL font handling, don't see a bug here, it is doing what
is expected. 

While enhancement to actually align on the 0 base would be at odds with what
other word processors do, don't see much demand there.
