Revert 211664 "Shows Japanese and English mixed queries correctly."

> 
> The cause of vertically-misaligned queries was that
> 1. ASCII characters have 23 pixels in height
> 2. Japanese characters have 17 pixels in height
> 
> pango_layout_get_pixel_size(), which is called in RenderTextLinux::GetStringSize(), returns the above size.
