Read http://www.openbsd.org/papers/eurobsd2005/herrb-hopf.pdf
for an overview of modern X features.

In this paper, there is. You will also find a lot of information on the
wiki pages of various distributions.

Compositing has *nothing* to do with 3D. Xgl also does *not* provide you
with a 3D GUI interface. In fact, there is no 3D GUI interface designed
so far I know of (that has more than accademic use).

Does it? I'm surprised, it's dead slow compared to X for me.
