There is DGA support as of lib3d-0.1.5.  

WARNING
-------

DGA is currently quite fragile - if you interrupt a running DGA demo,
your screen will not be restored and you will have to do a blind reboot.


GETTING IT TO WORK
------------------

You will need one of the current (3.2) XFree86 X servers
with DGA support.  You can check this by looking in the Extensions
section of `xdpyinfo`.

You will also need the Xxf86dga client-side library.  This should be
auto-detected by the configure script.

DGA requires root priveleges.  Therefore you must either run the
program as root, or make it setuid root.
