Re: ["gtk-i18n-list"] Font Rendering backends

Thanks!

Ahhh, the difference is slightly different what I expected
(I expected some hinting or subpixel rendering configuration
is different between terminator and emacs) - the difference
seems to me as if the width of the glyphs are same, but the
height of the characters are different (although the linegap
is still same). It's hard for me to think as the terminator
or emacs invokes the font rasterizer with non-1:1 aspect ratio,
so I have no idea what causes this difference. I want to hear
other experts comment...
