Re: A patch for enforcing double-width CJK character display

[黄建忠 <jianzhong.huang@i-soft.com.cn>]

Thanks for reply.
I checked with "text-scale-increase" and it did not work.
When scale happened, the space_width and column_width of frame did not 
changed, I need find another way to get monospace font width after scale.
But I think we can store the default font face to every xftfont_info and 
when scale happened, re-caculate the space width of default face.
Let me try, thanks for the feedback.
