The X server does it for legacy applications using the 20-year old
X11 font calls. Fonts rendered this way have many limitations, and
are not antialiased. This remains for backwards compatibility.
Modern applications use freetype on the client side, with libraries
such as libXft & pango to handle more complex rendering with newer
features such as anti-aliasing/lcd-optimization.
