[Fontconfig] blacklist/whitelist grammar and pseudo-bolding

[Qianqian Fang]

hi

I am preparing a font installation script for our bitmap CJK fonts. A 
fontconfig file
was included in the package to allow the use of vector CJK fonts and 
bitmap fonts
simultaneously. This file can be found at
  http://wenq.org/eindex.cgi?85-wqy-bitmapfont.conf

Some friends told me that their fontconfig complained "unknown element: 
selectfont/acceptfont/pattern/patelt"
I guess this selectfont syntax was only supported in recent versions, 
can anyone tell me
which version number is the first one supporting this? is there a better 
way to bypass
this block other than by examining the out put from "fc-list --version" 
and remove the
block from the file in the installation script?

my second question, I am not sure if proper for this list, is how to 
tell if the rendering
engine (freetype2) on a system can generate pseudo-bolding face for a 
bitmap font?
(in that case, I can get rid of the bold face files to save half of the 
space).

thanks
