[XeTeX] XeTeX vertical text layout support (for Linux & win32 users)

[Jjgod Jiang]

Now you can understand what I wished for, if some fonts don't
provide such feature (ex. HanWangMingMedium), or provide
features we don't want to use (ex. AdobeSongStd-Light).We
could have some ways to select or adjust such stuff like
punctation position.

My question is, in which level we should implement these
adjusting feature? TeX level or TeX macro level? or we should
fix the font (or make a second copy of the font) instead?
