MLAA affects all rendering that goes through OpenGL. While the text rendering
for non-GL X apps may be rendered by the ddx using xrendr, the pixmaps end up
going though OpenGL if you are using an OpenGL compositor (gnome
shell/compiz/kwin/etc.). When the application window is composited to the
front buffer by the OpenGL compositor, the MLAA is applied.</pre>
