 The reason I mention freetype and fontconfig is because back-xlib has 
several implementations.
 The oldest one only supports latin character (XDrawString)
 A newer one use XFontStruct to display multibytes character 
(Xutf8DrawString)
 And there is one which use Xft (freetype) and/or fontconfig to draw 
character (XftDrawString16).
 I didn't look into the details of each implementation.
 The first and second one use the Xwindows functions,
 and the third one requires third-party libraries.
 And there are two defaults: GSFontAntiAlias and GSXEnableFontSet.
 So there is four possibilities:
 AntiAlias: NO, FontSet: NO => XDrawString()
 AntiAlias: NO, FontSet: YES => Xutf8DrawString()
 AntiAlias: YES, FontSet: NO => XftDrawString16(), create font cache if 
fontconfig doesn't exist
 AntiAlias: YES, FontSet: YES => unknown

 I think normal user will be very confused why their fonts doesn't work or 
show up in font panel
 because of the defaults and installed libraries.
 Maybe we should at least remind them the freetype and fontconfig is 
required in the document.
