Okay, It was fixed.

Okay. I corrected to "margine" from "margine-right".

Processing of anti-aliasing is system dependence.
Therefore, I think it is better to turn off anti-aliasing. Then, I 
checked WorkingDraft of Font-Module.
At old WorkingDraft, although it seems that there was a property of 
font-smooth, there is no now.

It checked also here. It seems that it is different also by webkit and 
Although a system cause can be guessed, I think that it is very 
difficult to create exact reftest
  in the present condition.

I sent e-mail to Mr. Ishii, but there is still no replay.
