I used to use Hummingbird Exceed on Windows XP as my X server. Now
that I have a Mac, under 2.2, I recently noticed, using xemacs from a
remote machine running Fedora FC9, that the fonts "weren't as pretty as
I was used to". (See, even I know that's a vague and useless
description.)
I did a quick check of Exceed 2007, installed under Parallels, and
confirmed that "things looked different". The font was the same font,
nominally, but something was different: anti-aliasing, subpixels,
hinting, I have no idea. Exceed's font is also taller, but I think
there are other differences.
I haven't done any digging yet. I tried to do some Googling, but these
days, most X usage is apparently local, and it's really hard for a
novice (me) to understand which parts happen on the X client or its
linked libraries and OS, and which parts on the X server and its
OS.
So, before I go digging: Is font rendering one of those things that is
known to be "not yet there" in Xquartz? I saw many discussions about
Apple's IP in font hinting, but I would assume (perhaps wrongly) that
this isn't an issue if the X server and its OS are both from Apple -
especially if it worked before with an X server on Windows.
I've put a screen shot of Xquartz vs. Exceed here:
