I finally got around to get the code from the vcs and have a look at it.

Do you guys have any documentation on Libart? If yes, could you maybe send it to
me, or point me to a web page?

I had a look on the Libart homepage (http://www.levien.com/libart/) and followed
the link to the gnome project from there
(http://developer.gnome.org/doc/whitepapers/canvas/canvas.html). It seems that
GNOME is using libart without anti-aliasing, considering the output examples on
that page.
