XRender is used in a couple places.  Yes, it is used to make semi-transparent 
menus in KDE (which can be done if you're using the Keramik theme.  (in the 
effects, you should be able to enable menu transparency, and adjust a slider 
to select how transparent you want your menus.  It's also used by xft to 
produce anti-aliased text - the edges of letters are actually 
semi-transparent so they blend into their backgrounds.
