[ft] Vertical Text and Rotated Characters

[Darrell Bellert]

Greetings -

I am using freetype2 to render Asian characters in a vertical layout.  
Although I am just beginning this task, I noticed that freetype seems to 
rotate all characters by 90 degrees when rasterizing in a vertical 
layout.  Although this is desirable for latin characters, this is not 
what I want for Asian characters.  I still want Asian characters to 
remain oriented upright and non-rotated.

Is the general assumption that it is the developer's responsibility to 
handle such cases?  So, for Asian character ID's, I should not request 
vertical layout of freetype - yet if I do that, how do I get vertical 
metrics for proper layout?  Is there some missing functionality in 
freetype that I am missing concerning the rotation of some characters in 
vertical layout?  Any pointers or background knowledge would be helpful 
here and greatly appreciated.

Thanks,

Darrell
