Various facilities in Libxft (which it built atop XRender) will do  
antialiasing, but when used in unintelligent ways can consume vast CPU  
resources.

See my recent post with "Subject: LibXft : xftglyphcore woes" (which noone  
has seen fit to reply to yet :-( ) for how it can go wrong.

 From the plain X Server POV, antialiasing is always going to be hard,  
because to do it you need to know the background color or pixmap, and the  
Xserver does not keep track of how you had earlier set it, so it is up to  
individual toolkits to keep track, and not all of them do.
