tdf#114556 fix vertical writing emphasis mark position.

1. Calculate emphasis mark offset from base line using
ascender + descender, so it won't be too close or even overlap
with the glyph. It's an approximate for ideographic embox right
or ideographic chraceter face right.

2. CJK Ideographs have different drawing base positions.
Besides, it seems that glyph bound rect isn't consistent among
platforms, so use glyph advance information ( pGlyph->origWidth )
to calculate proper position and center the emphasis mark along
glyph advance axis.
