修改ttf字体美化显示效果 by cnhnln@linuxfans
fontconfig .org
http://fractal.csie.org/~eric/fontconfig/
首先下载cnhnln制作修改的VeraSansYuanTi （8个都要下）：
http://www.linuxfans.org/nuke/modules.php?name=Site_Downloads&op=geninfo&did=2488
解压，得到8个ttf文件，复制到/usr/share/fonts目录
接着 $sudo gedit /etc/fonts/fonts.conf
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- /etc/fonts/fonts.conf file to configure system font access -->
<fontconfig>
<!--
DO NOT EDIT THIS FILE.
IT WILL BE REPLACED WHEN FONTCONFIG IS UPDATED.
LOCAL CHANGES BELONG IN 'local.conf'.
The intent of this standard configuration file is to be adequate for
most environments. If you have a reasonably normal environment and
have found problems with this configuration, they are probably
things that others will also want fixed. Please submit any
problems to the fontconfig bugzilla system located at fontconfig.org
Note that the normal 'make install' procedure for fontconfig is to
replace any existing fonts.conf file with the new version. Place
any local customizations in local.conf which this file references.

The Bitstream Vera fonts have GASP entries suggesting that hinting be
disabled below 8 ppem, but FreeType ignores those, preferring to use
the data found in the instructed hints. The initial Vera release
didn't include the right instructions in the 'prep' table. Fix this
by disabling hinting manually at smaller sizes (< 8ppem)
