Xgl is an Xserver that uses OpenGL for its drawing operations. Xgl engineer David Reveman has posted enhancements to Xgl and a new compositor, 'Compiz' with a request that it be added to the freedesktop.org CVS repository. Some operations like antialiased font rendering is noticeably faster with this technology, and future graphics hardware might only have support for 3D operations and no 2D core any more.
The source code for these packages can be found at http://www.freedesktop.org/Software/Xgl
Even more important, composite is always accelerated with Xgl, and it allows for very nifty effects using OpenGL-enhanced composition / window managers like compiz.
